Foreword
Latin America and the Caribbean are going through a series of major transitions — economic, social, po-
litical, demographic, and epidemiological. One area of public health concern clearly touches on them all,
namely, occupational health.
Until recently, occupational safety and health was relegated to the background, as countries in the region
focused on more visible endemic diseases. Yet, occupational illness and injury is now a leading cause of
morbidity among adults in the region and cannot continued to be ignored. Addressing occupational safety
is extremely complex; it requires dealing with overlapping responsibilities between ministries of labor and
health, and between private insurers and social security institutes. It also requires involvement with busi-
ness associations and unions, international trade negotiators, and environmentalists. Lastly, it requires
making decisions with significant distributional and health consequences.
This study is the result of a joint effort by the IDB's Region 3 and Sustainable Development Departments
which was undertaken to identify the major trends and issues related to improving occupational safety in
Latin America and the Caribbean. It shows that the region has a very high disease burden in this area,
and that economic patterns of employment and public regulatory responses make these health problems
more acute than in Europe or North America. The paper was discussed at an IDB conference entitled
"International Conference on Occupational Safety and Health" in June 2000, and served to draw attention
to these important issues. The study provides a firm grounding from which to address the dearth of poli-
cies in occupational safety, and it will help guide future IDB activities in this sector. It represents one
modest step along the way to a future of safer working conditions and better health in the region.

Introduction
Occupational safety and health (OSH) is in-
creasingly recognized by Latin American and
Caribbean governments and international organi-
zations as an important part of public health.
People spend one-third or more of each day at
work, so working conditions necessarily have a
strong effect on their health. But OSH concerns
extend well beyond the obvious health conse-
quences of work-generated illnesses, accidents,
and deaths. OSH is a key element in the proc-
ess of social and economic development, with
direct and indirect impacts on such areas as the
labor market, labor productivity, household in-
come, poverty, social security systems, interna-
tional trade, and the environment.
The Latin American and Caribbean labor force
is one of the fastest growing in the world. In
1980 there were 112 million workers (IDB,
1982), by 1998 the workforce almost doubled
reaching approximately 202 million (see Table 1
overleaf). The most recent data produced by the
International Labor Organization (ILO, 1998)
show that, despite recent privatization efforts in
the region, the public sector continues to con-
centrate the largest portion of the workforce,
followed by the service sector, manufacturing
and the primary sector. The differentiated
growth experienced by these sectors has
changed the relative distribution and the nature
of the labor force. The percentage of the labor
force employed in the primary sector decreased
by more than 2 percent in the last five years and
in the same period the manufacturing sector
showed a less marked reduction of 1.5 percent.
On the other hand, both the service sector and
the public sector experienced an increase in the
percentage of the workforce employed of 2.5
percent and 0.8 percent respectively.
Although OSH has a direct impact on more than
200 million workers and their families in the re-
gion the situation in the region is far from ade-
quate, largely due to three main factors. First,
there is a general lack of awareness regarding
the importance of a safe and healthy work envi-
ronment. Second, data on occupational acci-
dents, illnesses, and deaths tend to underestimate
the magnitude of the problem. Finally, the region
lacks the institutional capacity and infrastructure
needed to develop and sustain a safe and healthy
working environment. The region's failure to im-
plement or enforce appropriate safety laws
translates into lost production, lost wages, medi-
cal expenses, disabilities, and deaths.
This study describes the health dimension and
some economic aspects of occupational safety in
Latin America and the Caribbean. Section 2
gives a brief description of the main occupational
hazards in the region. Section 3 presents the
available figures about occupational accidents
and diseases in the region. Section 4 explores in
detail the occupational risks in agriculture, min-
ing, and the construction industry. Section 5 dis-
cusses the costs for Latin American and the
Caribbean countries. Section 6 considers policy
actions to improve OSH regulation and to im-
prove compliance with these rules. Section 7
concludes with a discussion of the main results.

Occupational Hazards in Latin America and the Caribbean
Millions of workers in Latin American and Car-
ibbean countries are at risk from exposure to
physical, chemical, biological and psychoso-
cial hazards in the workplace and many of them
are exposed to a combination of these.
Heavy physical workloads or ergonomically
poor working conditions can lead to injuries
and musculoskeletal disorders. Those most af-
fected include miners, farmers, lumberjacks,
fishermen, and construction workers. It is esti-
mated that between 50 percent and 70 percent
of the workforce in developing countries is ex-
posed to these types of hazards.
Other physical hazards such as noise, vibration,
ionizing and non-ionizing radiation, heat and other
unhealthy microclimatic conditions can adversely
affect health. It is estimated that between 10
percent and 30 percent of the workforce in in-
dustrialized countries and up to 80 percent in de-
veloping and newly industrialized countries are
exposed to a variety of these potential hazards.
Dangerous work conditions include activities
that may damage a worker’s health or put
his/her life at risk. Examples include deficiencies
in the design of the workspace, lack of or insuf-
ficient security devices, high level of risk in the
type of work and lack of protective equipment,
procedures, or training.
In addition to physical hazards, workers are ex-
posed to a variety of chemical hazards. Expo-
sure to toxic chemicals poses serious health
threats, potentially causing cancer, respiratory
and skin diseases, as well as adverse effects on
reproductive functions. Workers are often ex-
posed to hazardous chemical agents such as sol-
vents, pesticides and metal dusts.
Exposure to mineral and vegetable dusts rep-
resents other chemical and biological hazards.
For example, silica, asbestos and coal dust cause
irreversible lung diseases, including different
types of pneumoconiosis. Silicosis is the most
widespread cause of occupational lung diseases
such as tuberculosis and lung cancer, but it is
preventable. Vegetable dusts can cause a num-
ber of respiratory conditions (such as byssinosis)
and allergic reactions (such as asthma).
The risk of cancer from workplace exposure is
of particular concern. Around 350 chemical
substances have been identified as occupational
carcinogens. They include benzene, hexavalent
chromium, nitrosamines, asbestos and aflatoxins.
In addition, the risk of cancer also exists from
exposure to physical hazards such as ultraviolet
(UV) and ionizing radiations. The most common
occupational cancers include lung, bladder, skin
and bone cancer, leukemia and sarcomas.
Biological hazards are also widespread. Expo-
sure to biological agents (viruses, bacteria, para-
sites, fungi and molds) occurs in many occupa-
tional environments from agriculture to offices.
The Hepatitis B and C viruses, HIV/AIDS and
tuberculosis infection among healthcare workers,
and chronic parasitic diseases among agricultural
and forestry workers, are examples of these
types of occupational diseases.
Exposure to thousands of allergenic agents,
including vegetable dusts, is a growing cause of
work-related illness. A large number of allergens
have been catalogued which can cause skin and
respiratory diseases (e.g., asthma).
Finally, social conditions at work can also dam-
age workers’ health. Frequently, these condi-
tions manifest themselves in stress and its con-
sequences. Social conditions that can be injurious
to health include inequality and unfairness in the
workplace; management style based on the ex-
clusion of workers from the decision-making
4
process; lack of communication and poor organi-
zation of work; and, strained interpersonal rela-
tionships between managers and employees.
Stress at work has been associated with elevated
risks of cardiovascular diseases, particularly hy-
pertension, and mental disorders.
Some economic activities do not produce health
risks only for people at the workplace, but also
affect the surrounding community through envi-
ronmental contamination. Unquestionably, many
economic activities have seriously contaminated
water, air and foods, which, in turn, have nega-
tively affected the health of surrounding popula-
tions.
DEFINING OCCUPATIONAL RISKS
Occupational health risk can be described as the
possibility of suffering health impairments from
exposure to a hazard that originates in the work-
ing environment. In the risk-assessment litera-
ture, the term hazard typically refers to the
source of risk. The likelihood of harming health
from exposure distinguishes risk from hazard: a
risk is created by a hazard. For example, a toxic
chemical that is a hazard to human health does
not constitute a health risk unless humans are
exposed to it.
In relation to events that affect workers’ health,
it is possible to distinguish between work-related
accidents and occupational diseases. A work-
related accident refers to an event that directly
affects a worker’s health during the perform-
ance of work activities or activities that are di-
rectly connected with work such as commuting.
They usually refer to physical injuries that have a
clear causal relationship between the acute event
and the work activity. Occupational diseases
indicate the pathological process caused by the
repetition of a work-related activity, such as
prolonged exposure to hazards at work whose
effects are only manifest after long periods of
time. The effects on worker’s health are slow
and not clearly linked to work conditions. In
general, many of these diseases have multiple
potential sources, including life-style factors,
which make it difficult to establish whether or
not the condition is directly work related.
Moreover, the long latency period that charac-
terizes many occupational diseases complicates
the determination of the causal relationship be-
tween work, the work environment and the dis-
ease. In the region, recognition of occupational
diseases is further complicated by the lack of
training of health care providers in occupational
medicine.
PROBLEMS SPECIFIC TO
LATIN AMERICA AND THE CARIB-
BEAN
It is often argued that workers in Latin America
and the Caribbean pay a higher toll of deaths and
injuries than in other regions of the world. There
are various factors that have a negative effect
on work safety in the region: the labor market
structure, the availability of resources, unions, the
exposure level and the hazard profile, and the
presence of vulnerable groups in the workforce.
Labor Market: Informal Sector, Small
Enterprises and Unemployment
In Latin America and the Caribbean, a large
proportion of the economically active population
works in the informal sector of the economy,
which includes, according to the ILO definition,
the self-employed, domestic servants and micro-
businesses. Informal employment increased sig-
nificantly in the last decade, growing from 44.6
percent in 1990 to 47.9 percent in 1998 (Lora
and Marquez, 1998; ILO, 1999). In the formal
sector, small and medium enterprises constitute
an important portion of the region’s economies.
Employment in small enterprises (6-20 workers)
represents 25 percent of the total workforce;
small and medium business with less than 100
workers employ 57 percent of the total
workforce in the formal industrial sector (ILO,
1999; Hiba, 1997).
There are a variety of factors that increase ex-
posure to occupational hazards in the informal
sector and in small enterprises. First, when firms
5
are small, the fixed costs of reducing occupa-
tional hazards may be prohibitively high since the
firm cannot benefit from scale economies.
Along with other factors, this leads to the con-
clusion that “generally, the smaller the industry is,
the higher the rate of workplace injury and ill-
ness” (Loewenson, 1994; p.97). Second, when
firms have high turnover, they have less incen-
tive to invest in the training and attention to their
workforce (Foley, 1998). Third, informal eco-
nomic activities may be in sectors that are par-
ticularly hazardous such as construction, agri-
culture and small-scale mining, although other
sectors, like retail sales may be among the less
hazardous. A fourth factor is the absence of
monitoring of work conditions, which is a par-
ticular problem in informal workplaces that, often
by definition, operate outside formal legal stan-
dards and regulation. In such firms, workers are
also less likely to organize and monitor work
conditions themselves. Fifth, workers in informal
firms are less likely to be insured through their
employers. This eliminates the business’ incen-
tive to address occupational hazards as a way to
reduce insurance premiums or avoid litigation.
Sixth, whenever workers are less educated or
informed, they are more vulnerable to occupa-
tional hazards. Often, informal sector workers,
particularly those who work in agriculture or
construction, are among the least well educated.
Finally, particularly vulnerable populations, such
as children and the elderly, are disproportionately
employed in informal activities.
The labor market in Latin America and the Car-
ibbean is also characterized by high unemploy-
ment and underemployment rates and the gen-
eral absence of unemployment insurance, social
security insurance and income maintenance for
the unemployed and for those working in un-
regulated sectors of the economy. As a result
many workers may tolerate hazardous working
conditions rather than risk losing their main
source of income. This makes it difficult for
workers to undertake collective action to im-
prove working conditions, including limiting the
ability to mobilize strikes.
Fewer Resources for Enforcement,
Prevention and Research
Despite the fact that some countries have made
occupational medicine a required subject in
graduate courses for physicians, and that spe-
cialized courses train occupational health physi-
cians, safety engineers and nurses (Bedrikow et
al., 1997), OSH in Latin America and the Carib-
bean is still in its infancy and there are fewer
experts available, less safety equipment, less
monitoring equipment, fewer inspectors and less
enforcement than in developed nations (Delclos
et al., 1999). In addition, OSH research is
probably underfunded. Estimates show that only
about 5 percent of occupational health research
in the world takes place in developing countries,
which clearly demonstrates a severe imbalance,
between the share of the population, the severity
of the problem and the resources available in
these countries (Partanen et al., 1999).
Labor Unions
The history of occupational safety reflects a long
struggle by workers to establish rights to a
healthy working environment and employers who
have sought to deny or limit liability. Unions
have played an important role in helping workers
to solve a number of issues and problems
through collective actions that could not have
been achieved individually. In particular, even
though each individual worker has an incentive to
demand better working conditions, he or she also
faces a high risk of being individually sanctioned
or dismissed by their employer. By contrast,
organized workers are better able to express
their views and make demands. While these
collective actions can be directly against the in-
terests of employers, in many cases they can
promote increases in productivity that serve both
workers’ and employers’ interests. Studies have
shown that, in certain circumstances, unions can
be effective channels of communication and in-
formation for improvements in the organization
of work and productivity increase. Usually, to
play this kind of constructive role, union activities
have to be specific to an industry or firm and the
6
union itself must be accountable to its member-
ship through effective and democratic processes.
However, unions are not always independent
organizations that speak for the interests of their
rank and file, even in highly unionized countries
(Frumkin, 1999; Laurell, 1989). In fact, unions in
Latin America and the Caribbean have a check-
ered history. Some have faced severe repres-
sion under dictators and military regimes, while
others have been coopted to serve political inter-
ests that do not necessarily reflect the best inter-
ests of their membership and have not been im-
mune to the corruption. In many cases, unions
represent only a minority of workers, namely
those employed in formal workplaces. For these
and other reasons, unions in the region may not
have been able to play the same positive role in
improving working conditions as have their
counterparts in more developed countries.
Longer Exposure and Higher Hazard Pro-
file
Occupational risk is determined both by the level
and the duration of exposure to hazards. Work-
ers in developing countries tend to work longer in
the presence of occupational hazards than those
in more developed countries. For example, it is
common for employees in many Latin American
and Caribbean countries to work 50 or more
hours per week. Thus, even when work is done
in environments that are considered safe by
standards established in industrialized countries,
where the typical exposure is a 40-hour work
week, the longer work week may result in expo-
sure levels that exceed safety levels.
To some extent, occupational hazards are related
to national geography and natural resource en-
dowments. For example, particularly dangerous
occupations, like mining, play a relatively large
role in the region because it is endowed with
primary commodities such as tin, copper and
gold. Moreover, high altitude or tropical climates
may exacerbate the risk of certain occupational
injuries or diseases. The impact of such broad
factors varies significantly across occupations,
sectors and types of hazards. An evaluation of
their net impact requires detailed studies, but it
has been argued that the particular geography
and resource endowments of the region exacer-
bate workers’ exposure to occupational risks
(Michaels et al., 1985).
More Vulnerable Groups
In healthy people, exposure to occupational
health hazards may occur up to a certain level
without apparent effects because the human
body has the capacity to deal with such chal-
lenges. However, some individuals can be more
vulnerable because of their physical condition,
age or gender. For example, toxicological evi-
dence suggests that the health effects of expo-
sure to hazardous chemicals are increased by
malnutrition, and that a low protein diet increases
the toxic effects of pesticides (Calabrese, 1978).
A large proportion of Latin America and the
Caribbean is less healthy and, therefore, more
vulnerable to occupational exposure to toxic
chemicals or biological agents. Researchers have
also documented the increased susceptibility of
children and adolescents to toxic substances,
particularly those such as pesticides that affect
growth and development of the reproductive
system (Hunt et al., 1982). In addition, children
and adolescent workers may be at a greater risk
for injuries because of their lack of training and
experience (Root, 1980). Child labor is still
widespread in the region. It is estimated that
there are around 17 million children at work
(Tokman, 1997).
1
Many of the activities they
carry out are dangerous for their health and in-
hibit their development. Documented examples
include child labor in charcoal production in Bra-
zil, gold and coal mining in Colombia and Peru,
and manufacturing fireworks in Guatemala and
Colombia (Salazar, 1998; Harari et al., 1997).

1
A household survey carried out in Paraguay in 1990
showed that 5% of 12 years old were working (Patrinos and
Psacharopoulos, 1995) and even higher proportions of child
labor were reported in Brazil and Mexico (Forastieri and
Matos, 1993).
7
Women have been joining the workforce in i n-
creasing numbers and currently account for
about 40 percent of the economically active
population in the region (ILO, 1999). Although
the increased participation of women in the labor
force has improved their social and economic
well being, as well as the education and health of
their children (IDB, 1998), women are exposed
to greater health risks than their male co-
workers, and their increased role in the work-
place has not generally been met by an adequate
adaptation of working conditions to gender dif-
ferences (Cabrera, 1978). For example, women
of fertile age are more susceptible to occupa-
tional hazards that affect reproductive functions.
When pregnant, occupational hazards pose risks
to the growing fetus, which may lead to con-
genital defects and miscarriages, as well as long-
term impairments to children’s health and devel-
opment. Women may suffer from musculo-
skeletal disorders when the tasks or equipment
used are designed for the “average man” and not
adjusted to their different builds and physiology.
Women appear to suffer from
specific stress disorders that result from gender
discrimination in the labor market, a double bur-
den of work (workplace and home) imposed by
traditional and cultural roles, and also sexual har-
assment (WHO, 1999). For example, La Botz
(1994) in her study of the maquiladoras (firms
in Mexico’s northern free trade zone) showed
that working conditions for women were worse
than for men. Virtually all supervisors and tech-
nicians were men, while more than three-
quarters of the operational employees were
women. Women were more exposed to toxic
chemicals and dangerous work processes than
men, and sexual harassment was defined as “en-
demic.”

Occupational Accidents and Diseases in
Latin America and the Caribbean
The rate of occupational injury and illness in
Latin America and the Caribbean is difficult to
quantify for two main reasons. First, there is
underreporting of accidents and illnesses in firms
and sectors that are legally obligated to report
these events. Second, a large proportion of the
economically active population is employed in
sectors that are not required to report such inci-
dents. Thus, for a large portion of the workforce
information is not systematically collected.
The ILO is the principal source of statistics in
this area and publishes occupational accident
figures based on the national registration and
notification systems of the majority of the coun-
tries in the world (ILO, 1998). Tables 2 and 3
present ILO data on the number of fatal and
nonfatal occupational injuries and their distribu-

tion across economic activities. International
comparisons are difficult because registration
and notification systems are not consistent
across counties. In some countries the data
cover occupational diseases and accidents asso-
ciated with commuting, whereas in others they
do not. In addition, while for most countries the
figures refer only to the number of compensated
accidents, data for few countries include all re-
ported accidents. In general, it is likely that in-
consistencies are greater in the comparison of
nonfatal than fatal accidents.
Most fatal (43 percent) and nonfatal (50 percent)
occupational accidents occur in manufacturing,
utilities and construction activities. Moreover,
the ratio between the proportion of the
workforce employed in these sectors and the
distribution of accidents shows that workers in
such sectors are twice as likely to suffer acci-
dents. Wholesale and retail trade, hotels, restau-
rants, transport, storage and communications,
financial intermediaries, real estate, renting and
other business activities represent the second
grouping for the number of both fatal (37 per-
cent) and nonfatal accidents (29 percent). In
third place, we have activities in agriculture,
hunting, forestry, fishing, mining and quarrying,
where 11 percent of fatal and 17 percent of non-
fatal accidents take place. The last group is

Table 4 reports the fatality rate for occupational
accidents in Latin America and the Caribbean
for which data are available and compare it to
some nonregional countries such as Canada, the
United States, Finland and South Korea. Over-
all, the average fatality rate in Latin America and
11
the Caribbean is 0.135 per 1,000 workers, which
is just between the rates experienced by the two
biggest countries in the sample: Brazil and Mex-
ico.
3
However, there is a large variation in fatality
rates across the region, which vary from the ab-
sence of fatal accidents reported by Barbados in
1995, to the 0.33 accidents per 1,000 workers
recorded in El Salvador in 1998. The absence of
fatal accidents in Barbados can be explained, at
least partially, by the fact that its economy is
largely based on activities, such as tourism,
which present lower occupational risks. On the
other hand, the low accident rates in countries
like Trinidad and Tobago, and Venezuela may
simply reflect the deficiencies of the reporting
systems since primary extraction plays a large
role in both economies.
Looking outside the region, the occupational fa-
tality rates in established market economies were
significantly lower than the average rate for
Latin America and the Caribbean. In 1997,
Canada experienced a fatality rate that was al-
most half that of Latin America and the Carib-
bean, and even lower rates were recorded in
Finland and the United States. By contrast,
South Korea had a fatality rate in 1998 that was
twice the average for Latin American and the
Caribbean. This could be due to better registra-
tion or a heavier reliance on risky sectors (such
as heavy manufacturing). On the other hand, the
relatively higher fatality rate observed in South
Korea could also be explained by the very rapid
process of industrialization experienced under a
regime that, until recently, was quite repressive
of workers unions and workers’ rights.
Estimates for the Entire Population

2
For example, during the recent gold rush in Brazil, 90% of
gold production was coming from informal mining or
garimpos (Malm, 1998).
3
Since we have weighted the national rate by the number of
workers covered, the importance of the outliers is reduced.
As noted previously, disability compensation
systems in Latin America and the Caribbean do
not cover all sectors of employment. For exam-
ple, occupational accidents in peasant farming,
and domestic and urban informal sector employ-
ment were not included in the figures reported in
Tables 2 and 3. Indeed, Table 4 shows that in-
formation on fatal injuries was based on a rela-
tively small proportion of the workforce; for ex-
ample, accidents were reported for only one third
of the workforce in Brazil and Mexico. How-
ever, even in countries where the workforce is
covered by reporting systems, the poor identifi-
cation of occupational diseases and the legal and
bureaucratic features of the systems, raise ques-
tions about the validity and accuracy of the esti-
mates. For example, Keifer et al. (1996) used a
community questionnaire to estimate the degree
of underreporting in a regional pesticide poison-
ing registry in Nicaragua and showed that even
in a region with a strong emphasis on reporting
illness in targeted conditions, 65 percent of the
cases went unreported.
An important reason for this underreporting is
that the employer’s contribution to the social se-
curity fund for occupational injuries is often ad-
justed for the firm’s actual risk experience as
revealed by reported occurrences (see Appen-
dix). In some countries the insurance premium is
based on the broad rating of risk within the par-
ticular industry; that is, more dangerous indus-
tries have to pay higher premiums than less dan-
gerous industries, but all firms in the same indus-
try pay the same insurance premium. In other
countries the insurance premium is based upon
the safety records of each company, so that if a
firm is able to show that it has few accidents, it
pays lower insurance premiums, even if it be-
longs to one of the more dangerous industries.
This mechanism is designed to encourage em-
ployers to improve safety standards. However,
it encourages underreporting since firms have a

financial incentive to hide these events (Villegas
et al, 1996).

In order to estimate the total number of work-
related impairments in the region we use the
methodology suggested by Takala (1999), which
is based on applying the rates of the population
covered by reporting systems to the whole
workforce. The average rate of fatal occupa-
tional accidents is 0.135 per 1,000 workers and
the estimated workforce in Latin America and
the Caribbean was around 202 million in 1998.
Thus, about 27,270 fatal occupational accidents
are estimated to occur each year in the region.
5
This figure is more than three times larger than
the 7,443 fatal injuries reported in the official
ILO (1998) statistics for the region. Presumably,

4
Other effects of the use of experience-based insurance
premium are discussed in section 6.
5
This figure is very close to the 26,374 fatalities per year in
Latin America and the Caribbean estimated by Takala
(1999) using data from 1994.
27,270 is a conservative estimate of the actual
number of fatal occupational accidents as it is
based on the following assumptions:
? In the workforce covered by reporting sys-
tems all fatal occupational accidents were
reported.
? Fatality rates in the formal and in the infor-
mal sectors of the economy were the same.
? 50 percent of the workforce was employed
in the formal sector of the economy.
The estimate is quite sensitive to these assump-
tions. If any of the above factors is changed, the
estimate rises dramatically. In Table 5, we
modify these parameters so that only half of oc-
cupational fatalities are reported and the rate of
occupational fatalities in the informal sector is

50 percent higher than in the formal sector. Un-
der these assumptions, the estimate of total an-
nual occupational fatalities is 68,147 (see Table 5
and Figure 1).
Table 6 compares the rates of fatal occupational
accidents across different regions of the world
as estimated by Takala (1999). The lowest fa-
tality rate was observed in the established mar-
ket economies: 0.053 per 1,000 workers. If
workers in Latin America and the Caribbean
were exposed to the same risk of dying from
occupational factors as those in the established
market economies, more than 16,500 lives could
have been saved (using the conservative as-
sumptions). Although India, the former socialist
economies of Europe, and China have lower es-
timated fatality rates than Latin America and the
Caribbean, the region’s safety record is better
than that of Sub-Saharan Africa, the Middle
Eastern crescent and other Asia countries and
islands.

for fatal accidents, it is possible to derive a more
likely figure for nonfatal accidents using infor-
mation about fatal accidents. Various studies
have demonstrated that if the reporting system is
reliable, a roughly constant ratio between fatal
and nonfatal accidents exists (see Takala, 1999).
We use two ratios: 1 fatal accident per 750 non-
fatal accident is a conservative estimate and 1
fatal accident per 1,000 nonfatal accidents is the
observed ratio in countries with a more sophisti-
cated reporting system, such as Finland and the
United States (Leigh et al., 1996a; ILO, 1998).
Using this methodology, we conservatively esti-
mate between 20 and 27 million occupational
accidents causing 3 or more days’ absence from
work in Latin America and the Caribbean. A
less conservative estimate, using the alternative
ratio leads to an estimate of 51 to 68 million non-
fatal accidents each year.
Global Burden of Disease Estimates
An alternative way to look at the impact of oc-
cupational hazards and risks on health conditions
is to consider how many of these accidents and
fatalities are avoidable. Leigh et al. (1996b) un-
dertook an ambitious study aimed at estimating
the burden of injuries attributable to occupational
factors in a comparable manner across major
regions.
6
The burden of such injuries was estimated using
direct reports of occupational injury rates in
Scandinavia as a minimum attainable level and
applying them to each region. The study then
used data from some countries to extrapolate the
burden of disease in their respective regions.
Mexican data was used as the basis of the esti-
mates for Latin America and the Caribbean.
The study estimated about 97,700 occupational
fatalities in the region in 1990, which accounted
for 3.2 percent of all deaths (see Table 7).
According to this study, the region has the high-
est share of deaths attributable to occupational
factors in the world, which testifies to the exces-
sive level of life-threatening hazards that work-
ers face in the region. Note that this estimate of
fatalities is almost three times higher than the
figure estimated in the previous section. Given
the different methods that were applied, the fig-
ure of 27,270 fatalities previously calculated must
be viewed as an extremely conservative esti-
mate.
The number of fatalities gives only an imperfect
measure of the severity of the problem because

6
The results of this study are summarized in Murray and
Lopez (1996) and Leigh et al. (1999).
15
occupational fatalities tend to occur earlier in life,
on average, than other causes of death among
adults. Using years of life lost (YLLs) as the
unit of measurement adjusts for this fact and
yields a work-related burden of disease and inju-
ries of 1,973,000 YLLs. Even so, the relative
importance of occupational fatalities increases
only slightly, to 3.5 percent of the total. When
adjusting for the impact of occupational injuries
on quality of life, the share increases further.
Measured in terms of years lived with disabilities
(YLDs), occupational factors represent
1,708,000 YLDs, equivalent to 4.1 percent of the
total. Using these figures, occupational hazards
account for a loss of about 3.7 million disability
adjusted life years (DALYs), representing 3.7
percent of all DALYs in the region. Table 7
ranks the world’s regions according to the bur-
den of disease and injury attributable to employ-
ment. It shows that the established market
economies have the highest proportion of
DALYs attributed to occupational factors, fol-
lowed by China and the former socialist econo-
mies of Europe. Latin America and the Carib-
bean ranks fourth. These results can be ex-
plained by the inverse relationship between eco-
nomic development and the overall burden of
diseases with high DALYs such as those ob-
served in early life.
Murray and Lopez (1996) compared the disease
burden attributable to occupational exposures
with nine other major health risks whose relative
importance for the region is presented in Table 8.
From this perspective, occupational hazards ac-
count for a large share of DALYs that could be
reduced through modifying behavior or environ-
mental factors. It is surpassed only by alcohol
abuse (9.7 percent); poor water supply, sanita-
tion and hygiene (5.3 percent); malnutrition (5.1
percent); and unsafe sex (3.7 percent).
Two caveats should be considered when inter-
preting these figures. First, the estimates of the
burden of diseases are based on notification
systems that cover only a small portion of the
regions; therefore, the results have to be inter-
preted in light of the uncertainty and inaccuracy
of such extrapolations. Second, the estimates of
the risk factors are based on different method-
ologies, making comparisons between risk fac-
tors subject to considerable measurement error.
16
Agriculture, Construction, and Mining
This section explores in greater detail occupa-
tional risks in agriculture, construction, and min-
ing. These three sectors have been chosen for
the particular importance that they have for the
economy of the region and for the relatively
large proportion of occupational injuries and dis-
eases that occur in them. However, the majority
of the epidemiological studies presented in this
section may be subject to so-called “healthy
worker effect” bias. This problem is likely to
affect cross sectional studies producing an un-
derestimate of injury rates because only workers
who are still working (or alive) can be counted
(Monson, 1986). Hence, more accurate studies
would require gathering work histories over time.
OCCUPATIONAL HAZARDS IN
AGRICULTURE: PESTICIDE
POISONING
Until recently, most OSH activities took place in
the industrial sector. However, according to the
latest ILO figures, approximately 19 percent of
the region’s workforce is engaged in agriculture
and other primary sector activities. In some
countries (e.g. Honduras and El Salvador), this
share reaches one third of the total workforce.
Some types of occupational injuries, which are
related to heavy physical work, have the same
general characteristics as the accidents that take
place in the industrial sector. Other types of oc-
cupational accidents and diseases, such as pesti-
cide poisoning, are more specific to the agricul-
ture sector. Moreover, the exposure to these
hazards in the region is aggravated by the pres-
ence of nonoccupational factors such as chronic
parasitic diseases, infectious diseases and mal-
nutrition.
Changes in land use have greatly increased the
use of pesticides in the last decade. Between
1988 and 1993, world pesticide consumption in-
creased by an average of 20 percent across
countries. During the same period, Latin Amer-
ica and the Caribbean experienced an increase
of 40 percent. While, most pesticide consump-
tion occurs in the region’s largest countries (e.g.
Brazil), the intensity of pesticide use is greater in
smaller countries. For instance, Costa Rica con-
sumes 14 kg of pesticide per worker each year;
Panama uses 10 kg per worker; Colombia, 6.0
kg; Mexico, 4.5 kg; Ecuador, 2.5 kg; El Salvador,
2.5 kg; Brazil, 2.3 kg; Honduras, 2.1 kg; and
Guatemala, 1.7 kg. It has been estimated that 5
percent of the people who are economically de-
pendent on agriculture in the region work or live
in areas where intensive pesticide use occurs
(McConnell et al., 1993) and that 99 percent of
all deaths due to pesticide poisoning occur in de-
veloping countries (Kogevinas et al., 1994).
Acute pesticide poisoning is recognized as a
major public health problem in much of Latin
America and the Caribbean (Repetto and Baliga,
1996).
7
Numerous reports have been made of
acute poisoning from pesticides, along with esti-
mates of fatalities. Although poisoning may also
result from intentional ingestion, occupational
exposure appears to be the major cause of acute
pesticide poisoning in the region (Forget, 1991).
For instance, a recent study in Costa Rica
(Leveridge, 1998) showed that occupational ex-
posure was the most frequent cause of pesticide
poisoning (38.5 percent), followed by accidental
situations (33.8 percent) and suicide attempts
(22.5 percent). Furthermore, excessive or im-
proper use of pesticides can also have a negative
impact on the health of the general population

7
Workers may also be exposed to pesticides in the indus-
trial sector. A recent survey in a firm producing organo-
phosphate pesticides in Guanajuato (Mexico) found that
63% of the workers presented persistent symptoms and
that 15% suffered from acute poisoning from pesticides
(Palacios-Nava et al., 1999).
17
Box 1 – Workers’ Health and Productivity: The Case of Potato Production in Ecuador
In a recent study, Antle et al., (1998), estimated the effect of a policy to reduce pesticides use in potato
production in Ecuador. To examine the health impacts of pesticides use, the authors conducted a survey
of the farm population and a control group not exposed to pesticides, which revealed serious neurobehav-
ioral damage was being caused by exposure to pesticides. Next, they estimated the impact of workers’
health on potato production, which turned out to be negative and statistically significant, indicating that
farmers with higher neurobehavioral problems had higher costs of production per hectares, and thus, lower
productivity. The authors performed a simulation analysis and showed that restricting the use of pesticides
that posed the greatest health risks was a “win-win” policy. In other words, farmers would be healthier and
more productive if the use of some pesticides (e.g. carbofuran) were reduced. Because the productivity
gains obtained from the improvement in workers’ health outweighed the negative productivity effects of the
reduction in pesticide use, both workers and employers would be better off. However, the win-win outcome
can be obtained only when the policy targets the insecticides that pose the greatest health risk. When the
effects of a policy aimed at reducing the use of all pesticides was considered, a trade-off between health
and productivity emerged. In such cases, an increase in workers’ health could only be obtained at the cost
of a reduced harvest.
through the consumption of agricultural products
highly saturated with such chemicals.
Studies in Latin America and the Caribbean indi-
cate that most workers who spray and apply
pesticides do not use adequate protective cloth-
ing. It has been suggested that protective cloth-
ing made of plastic or rubber material is designed
for colder climates and may cause excessive
discomfort in hot, humid climates. Regardless of
the reason, several authors have noted that
safety instructions regarding changes of clothing
and bathing after spraying are not followed prop-
erly in the region (Condarco Aguillar et al., 1993;
Arroyave, 1993). Moreover, illiteracy among
agricultural workers probably reduces the use-
fulness of written or printed instructions.
Table 9 summarizes the studies we have identi-
fied on the occurrence of illnesses associated
with the use of pesticide in the region. Cases of
pesticide poisoning among agricultural workers
are frequent, but rates vary widely. A recent
survey in the state of Yucatan (Mexico) found
that 40 percent of the sample sought health care
in one year because of illnesses due to occupa-
tional exposure to pesticides. A study in Brazil
estimated that lifetime incidence of pesticide poi-
soning among diversified farmers was “only” 12
percent. High levels of pesticide poisoning were
reported by agricultural workers in both Costa
Rica and Nicaragua, but were much lower in the
former (4.5 percent per year) than in the latter
(25 percent per year). Beyond acute poisoning,
pesticide exposure can lead to permanent pe-
ripheral nervous system damage. This was
demonstrated in a study in Ecuador that showed
that exposed agricultural workers had a higher
incidence of neurobehavioral dysfunction than
town residents who were not exposed to pesti-
cides (Cole et al., 1998). It must be noted, how-
ever, that there are conditions in which reduced
pesticide use can lead to actual improvements in
agricultural productivity (see Box 1 below).
OCCUPATIONAL HAZARDS IN THE
CONSTRUCTION INDUSTRY
The construction industry accounts for a large
number of occupational accidents in Latin
America and the Caribbean (Castors de Pontes,
1999). Construction workers perform dangerous
activities such as working on foundations, scaf-
folding, laying concrete and moving earth. The
most common types of accidents are:
? Injuries caused by falls from ladders, lifts
and scaffolds. Falls consistently account for
the greatest number of fatalities in the con-
struction industry. These types of accidents
often involve a number of factors including

unstable working surfaces, the misuse of fall
protection equipment, workers slipping or be-
ing struck by a falling object. Studies have
shown that the use of guardrails, fall arrest
systems, safety nets, covers, and travel re-
striction systems can prevent many such
deaths and injuries.
? Injuries caused by defective or negligently
operated cranes, hoists and derricks. The
most common cause of fatal accidents in this
category is cranes coming into contact with
power lines. Other major causes of crane
accidents include assembly and dismantling
the crane, boom buckling, rigging failure and
upset, and crane overturning. Many of these
accidents are preventable and are usually
caused by poor safety procedures and negli-
gence.
? Accidents related to dangerous equipment,
tools and machines. Moving machine parts
have the potential for causing severe work-
place injuries, such as crushed fingers or
hands, amputations, and burns and blindness,
among others. Equipment with appropriate
design and protective features, along with
training in safe operation, are essential for
protecting workers from many of these
needless and preventable injuries.
? Injuries caused by explosive, corrosive
and poisonous gas. Many operations and
construction projects require the use of com-
pressed gases, which may be combustible,
explosive, corrosive, poisonous, inert or pose
some combination of hazards. The safe de-
sign, installation, operation and maintenance

appropriate codes and standards are essential
to worker safety and health.
While these risks are common to construction in
all countries, the region’s climate (heat and hu-
midity) plus the lack of adequate protection and
training exacerbate risks in this industry (Amaral
et al., 1999). Table 10 presents a summary of
studies that have analyzed occupational hazards
in the region’s construction industry showing just
how dangerous it is to work in this sector. For
example, between October and December 1988
the largest share of all work-related accidents
(i.e. 8.2 percent) in Sao Paulo, Brazil occurred in
the construction industry (Santos et al., 1990).
Studies also found that the construction industry
has the highest occupational risk in Chile (Aso-
ciación Chilena de Seguridad, 1999) and high
injury rates were also reported among builders in
the province of Antioquia, Colombia (Nieto-
Zapato, 1992).
OCCUPATIONAL HAZARDS IN MINES
Primary extractive industry is an important eco-
nomic activity in many countries in Latin Amer-
ica and the Caribbean. It is estimated that cur-
rently there are between 543,000 and 1,039,000
miners in the region, while during the peak of the
gold rush there were more that 1.6 million miners
in Brazil alone (Malm, 1998).
The extractive industry presents a high incidence
of occupational illness and injuries. A mine is an
extremely dangerous environment. Accidents
may occur from collapsing roofs, falls, electrocu-
tion, use of dangerous equipment, and explosives.
Inadequate engineering controls, protective
equipment and medical surveillance compound
the occupational risks of mining and related ac-
tivities in the region (see Table 11). For in-
stance, a study of occupational injury among coal
miners in the province of Antioquia, Colombia,
estimated a rate of 522 accidents per 1,000 full-
time workers per year, while the rate for similar
mining activity in the United States was only 152
accidents per 1,000 workers (Frumkin, 1999).
Silicosis, recognized as a major occupational
health problem among miners, deserves special
attention. It results from the accumulation of
silica dust in the lungs and the reaction of the
tissue to its presence. A strong association be-
tween silicosis and lung cancer after occupa-
tional exposure to dust containing crystalline sil-
ica has been established (Boffetta et al., 1994).
Exposure to silica dust measured among workers
in the crushing plant of a copper mine in Chile
showed that the level of respirable silica dust
was 189.5 mg/m

Table 11 shows that sili-
cosis is a major occupational disease in the re-
gion, which affects between 15 percent and 22
percent of miners in countries like Bolivia, Chile
and Colombia.
Silicosis is not the only health threat faced by
miners. They are also exposed to coal dust that
can cause black lung disease, and high concen-
trations of metals that can cause neurological
damage. Exposure to manganese, for example,
has been associated with a measurably higher
prevalence of abnormalities in physical move-
ment, such as dystonic rigidity and proximal
tremor (Hochberg et al., 1996). The large quan-
tity of mercury released into the environment
during gold extraction, particularly prevalent in
the Amazon region, constitutes an increasing
concern for its potential danger both to the min-
ers and the population living in the immediate

area. Metallic mercury is used for the amalga-
mation of gold, and mercury is released by
evaporation at reburning sites. The first extrac-
tion (burning) is performed in the field by the
garimpos (informal miners) and the second (re-
burning) in gold shops in towns. This practice
may expose workers to health risks from inhaling
elemental mercury. Moreover, mercury is re-
leased in substantial amounts into rivers and
lakes and may accumulate as methylmercury in
aquatic food chains.
Mercury has been used in gold extraction in Bra-
zil, Venezuela, Colombia, Bolivia, Guyana,
Suriname, Ecuador and Peru since the 1980s
(Malm, 1998).
The best documented case is Brazil, where five
million people are estimated to be exposed to
health hazards derived from the occupational use
of mercury. This figure includes people living
along rivers who eat contaminated fish, as well
as those exposed to metallic mercury released in
the mining areas and in the urban shops (Câmara
and Corey, 1992).
21
Whenever mining is done informally, proper
oversight is lacking and occupational hazards
tend to be more severe. And when international
prices of primary products fall, reducing profit
margins, expenditures to protect workers’ health
may be the first ones to be cut. All in all, these
factors make mining one of the riskiest sectors in
the economy.

Costs and Economic Aspects of Occupational Health
Data on the economic consequences of occupa-
tional accidents and diseases are very scarce,
both in developed and developing countries. The
most rigorous available study of the economic
costs of occupational injuries and illnesses at the
national level was produced in the United States,
where it was estimated that they represent ap-
proximately 3 percent of the gross domestic
product (GDP) in 1992 (Leight et al., 1996a).
The ILO and the WHO have produced estimates
of the total burden of occupational accidents
suggesting that their cost may reach as much as
10 percent of the GDP of developing countries
(PAHO, 1999; p.11).
The only information available for Latin America
and the Caribbean derives from the national so-
cial security systems, which include health care
expenditure and pensions for work-related dis-
abilities and deaths. The Pan American Health
Organization (PAHO) has recently produced a
report with information from several Latin
America countries (PAHO, 1998), summarized
in Table 12. The situation among countries var-
ies. In Costa Rica, where the National Insur-
ance Institute covers 68.4 percent of the coun-
try’s workforce, direct expenditures (care and
indemnification for occupational injuries and dis-
eases) and administrative costs amounted to
US$47.9 million in 1995, representing nearly
US$70 per insured worker. In other countries
expenditures were significantly lower. For in-
stance, expenditures in Chile were US$33.80 per
insured person in 1996, and Mexico showed the
lowest expenditure with just US$21.26 per in-
sured worker. Considering data from all the
countries, the average social security expenditure
per insured person amounted to US$30.62 per
year.
Almost nothing is known about the costs borne
by other social actors such as the private sector,
families and the rest of the community. The
“hidden costs” for firms from work-related acci-
dents are estimated to be, on average, four times
the immediate direct costs related to workers
compensation (Heinrich et al., 1980). These hid-
den costs include loss of production due to time
spent recovering, lower productivity upon re-
turning to work, and lost production caused by
the reduction of other workers’ productivity, ei-
ther because their work depends on and com-
plements that of the injured worker or because
the injury reduces morale and increases stress.

In addition, there may be damage to equipment,
machinery, materials, or facilities caused by the
accident and official figures do not include com-
pensation that may be paid out by the firm in ad-
dition to social security.
Second, even when workers or survivors receive
social security benefits due to occupational acci-
dents, these benefits may not compensate them
completely for the economic costs (e.g. loss of
income, extra expenditures on medicine), and
nonmonetary costs (e.g. contribution to home
activities, pain and suffering) incurred. Moreo-
ver, around 50 percent of the regional workforce
is employed in informal activities and is typically
excluded from social security and labor legisla-
tion. Thus, the costs related to this part of the
workforce are primarily borne by the workers
and their families.
Finally, costs for occupational injuries also spill
over to other sectors of the economy. For in-
stance, occupational accidents may increase the
demand for public health services and services
from other welfare agencies. These public
health care services are usually financed out of
general revenues and are borne by taxpayers.
This cost is not easy to estimate. However, a
recent study found that agrochemical poisoning
in Yucatan (Mexico) cost the regional economy
US$2.7 million per year (equivalent to 2 percent
of the value of agricultural production), and 30
percent of this cost was borne by the state medi-
cal system (Drucker et al., 1999).
Table 13 and Figure 2 present some independent
estimates of the economic costs of occupational
accidents and injuries. Using the average social
security expenditure of US$30.62 per insured
worker yields a conservative estimate of US$24
billion in social costs due to occupational acci-
dents and injuries, representing about 1.8 percent
of GDP annually.
After adjusting for certain factors (namely the
actual costs to formal sector workers beyond
social security benefits, the ratio of productivity
to social security costs, and the ratio of external-
ities), we get an alternative estimate of social
costs of about US$55.5 billion. This represents
about 4 percent of annual GDP, which is not
quite as high as the ILO and WHO estimates,
but still represents a considerable cost to society.

Regulation and Incentives to Promote Occupational Safety
We have shown that the rate of occupational
injuries and diseases in Latin America and the
Caribbean are high. The burden is likely to be
heavier for those who can least afford it, such as
persons employed in informal activities with
lower wages, fewer opportunities for advance-
ment, and that lack compensation for occupa-
tional accidents and diseases. Above all, the
price paid for occupational injury, disease and
death is unnecessary, as countries in other re-
gions show that it is possible to achieve higher
levels of safety.
What, then, should be done to improve safety?
How much should occupational hazards levels be
reduced before the workplace can be considered
safe?
There are two broad views regarding the need
for public interventions to introduce and enforce
OSH standards. Some authors have argued that
in a world of perfect markets and complete in-
formation workers in riskier jobs would receive
higher wages to compensate them for the risk.
Thus, public interventions such as OSH regula-
tion and mandatory insurance for occupational
accidents would be unnecessary. For example,
Thaler and Rosen (1976) developed a theoretical
model, with a perfectly competitive labor market,
risk averse workers, perfect information about
risks of accidents and perfect worker mobility, in
which firms had different risks of accidents but
could influence the probability of accidents by
undertaking safety expenditures. They showed
that under these assumptions, workers’ compen-
sation insurance was unnecessary and govern-
ment regulation was harmful.
However, because there are labor market ineffi-
ciencies and incomplete information reality is
quite different (see Rea, 1981). For example,
employers and insurers may not be able to iden-
tify workers who are accident-prone and this
type of misinformation leads to a problem of ad-
verse selection. Moreover, in the working envi-
ronment there are serious monitoring constraints:
workers do not have the technical capacity to
estimate occupational risk accurately and to
monitor whether employers are taking proper
precautions. Thus, employers may not have
adequate incentives to reduce risks in the work-
place. The presence of involuntary unemploy-
ment undermines the assumption that workers
receive a “fair” compensation for higher risks.
In general, it has been demonstrated that if the
labor market presents imperfections, mandatory
insurance and safety regulation raises the ex-
pected utility of risk-averse workers (Diamond
1977; Oi, 1974). Thus, the state or some collec-
tive agency should be in charge of evaluating
safety and introducing regulations, norms, stan-
dards, incentives, or sanctions to enforce them
when necessary.
HOW MUCH SHOULD OCCUPATIONAL
RISK BE REDUCED?
Even if the need to introduce regulations, norms
and standards to reduce occupational risk is rec-
ognized, it is not clear what the desirable out-
come should be. In some cases, the answer is
simplified because there is no trade-off between
improved safety and costs. When reducing oc-
cupational hazards improves productivity, then
the decision to dedicate funds, provide incentives,
regulate or take legal action is unequivocal. For
example, the study summarized in Box 1 demon-
strates that the loss of productivity in potato pro-
duction from decreasing pesticide use could be
more than offset by the increases in productivity
resulting from improvements in workers’ health.
26
Box 2 – Cost-Effectiveness Study on Health Interventions to Prevent Work Injuries
In a recent paper, the Instituto Mexicano del Seguro Social (Salinas et al., 1999) reviewed the rele-
vance of conducting a cost-effectiveness study to improve safety in the workplace. The study, based
in Northern Mexico in the metal working industry, covered 82,034 workers registered in this type of
industry in 1998. Health interventions were ranked according to the estimated cost-effectiveness,
where effectiveness was measured through the number of healthy life years (HEALY) gained from
each intervention.

Education was revealed to be the most cost-effective intervention and security shoes the least cost-
effective in preventing injuries in the metal-working industry. This type of analysis can help decision-
makers to set priorities between different interventions when resources are constrained and select
the most cost-effective interventions to increase safety at work.
A seemingly attractive approach would be to aim
for the minimum level of risk. However, the
“minimum risk” for occupational hazards is diffi-
cult to define without relating it to some other
objective. If “minimum risk” is defined as “no
risk,” then it is unattainable and could only be
achieved in a society where no one worked
(Murray and Lopez, 1999). In practice, we can
only hope to reach an efficient level of risk, that
is, a level of risk that takes into consideration
both the potential benefits of greater safety along
with the expected costs or problems that emerge
from achieving that reduced level of risk. Alter-
natively, we could aim for some threshold of
risk, for example 1 in a million or “the same risk
as in the average home.” Such thresholds are
difficult to set because they may appear arbi-
trary. But they also fail to address the societal
costs of prevention, which preclude others bene-
ficial uses of those resources. A third option is
to aim for a socially efficient level of risk
where the potential benefits of a marginal im-
provement in safety equal the expected costs
that result from that reduced level of risk.
If the costs of attaining an improvement in occu-
pational safety are trivial and the benefits are
large, the decision to proceed is obvious. How-
ever, in other cases, it becomes more difficult to
judge whether or not safety improvements that
go beyond a certain level of risk reduction cost
more than they are “worth.” Presumably, the
countries of the region have many opportunities
to improve occupational health and safety in
ways that are cost-effective given the general-
ized lack of safety provisions and the excessive
rates of fatalities and nonfatal injuries that were
documented above. Simple measures such as
adequate ventilation and unobstructed work ar-
eas can go a long way toward reducing occupa-
27
tional risks in the region (see Box 2).
However, when policies to reduce occupational
hazards generate a trade-off between workers’
health and productivity or jobs, weighing the
costs and benefits of improved occupational
safety may be difficult, both technically and po-
litically. Some public agencies have sought to be
explicit in quantitatively evaluating the risks that
can be avoided by a particular measure and as-
signing them a monetary value that can be di-
rectly compared to the costs of implementing the
measure. By law, the United States government
is required to perform such quantitative analyses,
which has led to efforts to estimate the “value”
that should be attributed to saving a life. Viscusi
(1993) surveyed the US literature and found that
the implicit value of life was estimated between
US$600,000 and US$16.2 million – a wide range
of values that is also subject to a variety of
methodological, if not ethical, critiques (see, for
example, Dorman, 1996).
When such technical evaluations of occupational
safety measures are undertaken, there are at
least two issues that are rarely addressed, but
which are of great importance. First, an evalua-
tion cannot assume that technology will remain
static. In fact, we know that technology changes
constantly in ways that change the relative costs
of production, generating safer materials and
processes even while it may introduce new and
unknown dangers. But more importantly, estab-
lishing standards and imposing requirements can
actually induce technological advances. Many
examples are available from cases where new
materials have been developed to replace ones
that were harmful to human health or the envi-
ronment, such as PCBs, Freon, and lead in paint.
The second major issue is related to the distri-
bution of benefits and costs. In cases where a
trade-off between worker safety and productiv-
ity occurs, the benefits of improved safety will go
to the affected workers, while the costs of im-
provements may be borne by shareholders
(through reduced earnings), consumers (through
higher prices), and/or other workers (through
higher unemployment). Where the benefits are
large and costs are small, the distributional con-
sequences will be minor. But in cases where the
benefits and costs are of similar magnitudes, dis-
tributional consequences will be of greater i m-
portance and cannot be ignored.
In reality, few decisions about safety measures
and regulations are made purely through techni-
cal analysis. In fact, existing occupational safety
levels are really the outcome of many social
forces, at different levels and in many places.
Workers have struggled for improved working
conditions both through direct negotiation with
firms and business associations and through po-
litical pressure (Dorman, 1996). Collective ac-
tion can solve a number of problems that individ-
ual initiatives cannot. Two of these problems are
related to competitive pressures and information
costs. Competitive pressures make it difficult
for individual firms to take the lead in improving
occupational safety standards when these raise
their costs over those of their competitors. Thus,
collective enforcement of certain occupational
safety standards, by the government or even by
private industry associations, may be the only
way to assure that socially beneficial standards
are followed and “defections” from the common
agreement are limited.
Information costs are another impediment to the
adoption of better occupational safety measures.
It can be costly for a single firm or a single
worker to investigate occupational hazards and
remedies. By banding together in industry asso-
ciations or unions, collective actions can be taken
to research these issues and find effective ways
to better working conditions. “Induced technol-
ogy,” referred to earlier, can be one result of
such collaborations. In many cases, govern-
ments take on this role of improving the amount
and kinds of information that are available to
workers and firms. Ashford (1976) provided a
justification of imposing OSH regulation based on
the argument that these standards represent a
“public good.”
28
Public information about occupational hazards
and collectively established standards can assist
workers in several ways. On the one hand, the
existence of public standards can provide moral
backing to unions or groups of workers who are
trying to negotiate changes with a particular firm
or industry. On the other hand, the provision of
better information can improve decisions made
by workers regarding how much risk they are
willing to assume when taking a job or choosing
careers. One study simulated the effects of
tighter enforcement of safety standards in the
Mexican economy and demonstrated that more
stringent regulations can be beneficial to firms
and workers alike (Maskus et al., 1995). The
authors pointed out that this policy would im-
prove information in the market and better dis-
close the true level of hazards. Thus, tighter
safety standards had a positive impact on work-
ers and firms also benefited because pricing of
goods and wages incorporated more accurately
the occupational hazards of the various indus-
tries. Indeed, this effect was empirically demon-
strated in a study of Quebec’s manufacturing,
showing that the enforcement of occupational
safety and health regulations had a positive ef-
fect on productivity growth in the mid-1980s
(Dufor et al., 1998). Therefore, better occupa-
tional health and safety standards in the region
may benefit both employers and firms.
HOW TO INDUCE COMPLIANCE WITH
OCCUPATIONAL SAFETY
REGULATIONS
Information and promulgation of OSH standards
alone are not enough. Simply passing a law
commanding occupational safety does not auto-
matically reduce workplace hazards. Some
countries in the region have a reasonably com-
plete set of OSH laws and regulation, but en-
forcement is usually erratic and often absent
(see Frumkin and de Câmara, 1991).
Occupational safety agencies have often been
regarded as toothless tigers, unable to achieve
their stated goal because of the small number of
inspectors, few inspections, and the low fines for
noncompliant firms. However, there is some
empirical evidence that regulation, such as exists
in the United States, may have a relatively large
impact on business compliance behavior despite
a low regulatory profile (Well, 1996). These
studies indicate that government regulatory
agencies can substantially change private sector
behavior even with limited resources. This can
happen when firms make compliance decisions
on the basis of potential, rather than actual, pen-
alties. In this case, enterprises that believe they
will be subjected to the maximum possible pen-
alty arising from noncompliance may choose to
comply, even when the chance of detection and
sanction may be relatively small. Another way
that compliance is encouraged is through the
functioning of insurance markets and civil liabil-
ity. For example, industrial accidents that can be
attributed to a failure by the firm to protect
workers may subject that employer to costly liti-
gation and judicial awards, or to increased work-
ers compensation premiums. This suggests that
compliance with safety standards is the outcome
of a large suite of regulatory pressures formed
by workers compensation systems, private insur-
ers and the civil/criminal justice system.
Other important elements to consider are the
financial incentives created when there is insur-
ance for occupational accidents. Typically, the
presence of insurance, if the insurer cannot
monitor the precautions taken by the insured,
generates a problem of ex ante moral hazard.
That is, firms that know they are insured against
loss may take fewer precautions and actually
end up with a higher level of occupational risks.
In the case of insurance for occupational acci-
dents it is argued that there is the possibility of ex
ante “double moral hazard” (Lanoie, 1991) as a
workplace accident depends on precautions
taken by both workers and firms.
However, insurance incentives can also be used
to improve workplace safety. Occupational
safety agencies can promote a higher level of
safety in the workplace when they base the in-
surance premiums paid by the employer on the
firm’s previous safety record. In this case, in-
29
surance provides different incentives. It still de-
creases the cost of an accident to the worker,
which might cause him/her to be less careful, but
it increases the cost of an accident to the firm
because any accident leads to an increase in fu-
ture premiums. The net result depends on the
substitutability or complementarity of precautions
taken by workers and firms, the level of insur-
ance, and the insurance premium and the mar-
ginal increase associated with having a bad oc-
cupational safety record.
Empirical evidence regarding the impact of being
insured in Latin America is, to our knowledge,
limited to a single study for Mexico (Giuffrida et
al. 2000). In that case, workplace safety was not
strongly affected by insurance, at the given level
of experience rating, or at least was offset by the
moral hazard effect for workers and employers.
Since that data was collected, the Mexican So-
cial Security Institute (IMSS) increased the sen-
sitivity of the insurance premium to experience
rate, changing employers’ contribution from a
range of 0.348-10.035 percent to a range of
0.025-15 percent of payroll, going in the sug-
gested direction. And, the anecdotal evidence
from aggregate data (see ILO, 1998) suggests
that this policy has significantly reduced the
number of work-related accidents as reported in
the official registry.
Finally, there may be other factors that lead em-
ployers to be more responsive to occupational
health concerns that are less directly related to
economic incentives. In fact, there is an exten-
sive literature arguing that characteristics of the
firm itself will make it more or less receptive to
internal and external pressures for safer working
conditions. For instance, one study argued that
the most important determinant of a company’s
response to new occupational safety regulations
was its existing “safety culture” (Saari et al.,
1993). This was defined as a combination of the
importance that the company attaches to safety,
and its ability and willingness to take effective
action. Other characteristics of the work envi-
ronment that affect compliance is the degree of
workers’ participation, the presence of labor un-
ions, the relative power of the union, and the un-
ion’s level of internal democracy. In general,
studies in developed nations find that occupa-
tional safety is greater in countries and industries
where there is an open social and political dia-
logue about safe and healthy working conditions.
Also, when unions effectively represent workers,
occupational safety is enhanced both by creating
a favorable climate for protective measures and
by creating mechanisms to ensure compliance
with safety standards. In these terms, occupa-
tional health policies need to explicitly address
improvements in relations between workers and
management, and toward greater “democratiza-
tion” of industrial relations (see Dorman, 1996).

Conclusion
The countries of Latin America and the Carib-
bean have a very high incidence of occupational
injuries and diseases. This is due, in part, to par-
ticularly high risks in many of the region’s eco-
nomic activities, but also to limited collective ef-
forts to improve workplace safety. In fact, if
workers in Latin America and the Caribbean
were exposed to the same risk of dying from
occupational factors as workers in established
market economies, at least 16,500 lives per year
could be saved.
Furthermore, occupational injuries and illnesses
are seriously underreported in the region, a
problem that is even worse with nonfatal inci-
dents than with fatal ones. This is due to data
collection systems that are restricted to places of
formal employment, to reliance on employers for
notification in the face of incentives that discour-
age such notification, and to regular
misattribution of occupational diseases to other
sources of illness by physicians. More consistent
and standardized injury and disease surveillance
is clearly required.
It is apparent that occupational safety progresses
most rapidly in those economic sectors and firms
that employ vocal and politically organized work-
ers. A review of the limited evidence is suffi-
cient to identify key segments of the region’s
workforce that are poorly represented and who
are at particularly high risk of occupational injury
or death. These workers are occupied in certain
kinds of informal employment, and in agriculture,
construction or mining. Extending occupational
safety standards to these large segments of the
labor force in Latin America
and the Caribbean is problematic because of the
tension that may exist between the need to cre-
ate and preserve jobs and the seemingly less
immediate need of improving working conditions.
This tension exists in all developing nations and
may be expected to continue in the foreseeable
future. Nevertheless, attention to the problem
may allow us to find those areas in which simple
and low-cost actions can improve worker safety
without a negative effect on employment or
wages.
Latin American and Caribbean countries also
illustrate the disparity that often exists between
legislation “on the books” and reality. Some
countries in the region have a relatively complete
set of laws regarding occupational health and
safety, but enforcement is erratic. Legislation
alone cannot improve workplace conditions, and
consequently excessively hazardous conditions
persist. Instead, public policy needs to look be-
yond constitutional guarantees and legal provi-
sions toward a variety of measures that can alter
this situation. Such policies need to support the
generation and dissemination of information re-
garding the importance of occupational safety, its
costs, and its remedies. They also need to iden-
tify safety practices that can benefit both work-
ers and firms. Public policy must pay attention
to finding the most effective ways to induce
compliance with laws – whether through incen-
tives, audits, litigation, or direct supervision. Fi-
nally, public policy can promote safer working
conditions by encouraging and informing the
continuing debates between workers, firms, oc-
cupational health professionals, and regulators.
