INTRODUCTION TO OCCUPATIONAL
HEALTH AND SAFETY
HEALTH AND SAFETY
Goal of the Module
This Module provides trainees
with general background information on occupational health and safety, and on the
magnitude and variety of health and safety problems worldwide, and explains the role of
the health and safety representative.
Objectives
 |
At the end of this Module,
trainees will be able to:
(1) explain that occupational health and safety is more than accident
prevention — that it encompasses all aspects of working conditions;
(2) explain why management's
commitment to health and safety is crucial;
(3) explain why training is a
critical component of any health and safety programme;
(4) recognize a number of
occupational hazards and some of the types of work generally associated with those
hazards;
(5) discuss the range of
hazards in their own workplaces.

What is in this Module
 |
|
What is occupational
health and safety?
Occupational health and
safety is a discipline with a broad scope involving many specialized fields. In its
broadest sense, it should aim at:
- the promotion and maintenance of the highest degree of physical, mental and social well-being of workers in all occupations;
- the prevention among workers of adverse effects on health caused by their working conditions;
- the protection of workers in their employment from risks resulting from factors adverse to health;
- the placing and maintenance of workers in an occupational environment adapted to physical and mental needs;
- the adaptation of work to humans.
In other words, occupational
health and safety encompasses the social, mental and physical well-being of workers,
that is the “whole person”.
Successful occupational
health and safety practice requires the collaboration and participation of both employers
and workers in health and safety programmes, and involves the consideration of issues
relating to occupational medicine, industrial hygiene, toxicology, education, engineering
safety, ergonomics, psychology, etc.
Occupational health
issues are often given less attention than occupational safety issues because the
former are generally more difficult to confront. However, when health is addressed, so is
safety, because a healthy workplace is by definition also a safe workplace. The converse,
though, may not be true - a so-called safe workplace is not necessarily also a healthy
workplace. The important point is that issues of both health and safety must be
addressed in every workplace. By and large, the definition of occupational health and
safety given above encompasses both health and safety in their broadest
contexts.
Poor working conditions
affect worker health and safety
- Poor working conditions of any type have the potential to affect a worker's health and safety.
- Unhealthy or unsafe working conditions are not limited to factories — they can be found anywhere, whether the workplace is indoors or outdoors. For many workers, such as agricultural workers or miners, the workplace is “outdoors” and can pose many health and safety hazards.
- Poor working conditions can also affect the environment workers live in, since the working and living environments are the same for many workers. This means that occupational hazards can have harmful effects on workers, their families, and other people in the community, as well as on the physical environment around the workplace. A classic example is the use of pesticides in agricultural work. Workers can be exposed to toxic chemicals in a number of ways when spraying pesticides: they can inhale the chemicals during and after spraying, the chemicals can be absorbed through the skin, and the workers can ingest the chemicals if they eat, drink, or smoke without first washing their hands, or if drinking water has become contaminated with the chemicals. The workers' families can also be exposed in a number of ways: they can inhale the pesticides which may linger in the air, they can drink contaminated water, or they can be exposed to residues which may be on the worker's clothes. Other people in the community can all be exposed in the same ways as well. When the chemicals get absorbed into the soil or leach into groundwater supplies, the adverse effects on the natural environment can be permanent.
Overall, efforts in
occupational health and safety must aim to prevent industrial accidents and
diseases, and at the same time recognize the connection between worker health and safety,
the workplace, and the environment outside the workplace.
Why is occupational health
and safety important?
Work plays a central role in
people's lives, since most workers spend at least eight hours a day in the workplace,
whether it is on a plantation, in an office, factory, etc. Therefore, work environments
should be safe and healthy. Yet this is not the case for many workers. Every day workers
all over the world are faced with a multitude of health hazards, such as:
- dusts;
- gases;
- noise;
- vibration;
- extreme temperatures.
Unfortunately some employers
assume little responsibility for the protection of workers' health and safety. In fact,
some employers do not even know that they have the moral and often legal responsibility to
protect workers. As a result of the hazards and a lack of attention given to health and
safety, work-related accidents and diseases are common in all parts of the world.
Costs of occupational
injury/disease
How much does an occupational disease or accident cost?  |
 |
Work-related accidents or
diseases are very costly and can have many serious direct and indirect effects on the
lives of workers and their families. For workers some of the direct costs of
an injury or illness are:
- the pain and suffering of the injury or illness;
- the loss of income;
- the possible loss of a job;
- health-care costs.
It has been estimated that
the indirect costs of an accident or illness can be four to ten times greater than
the direct costs, or even more. An occupational illness or accident can have so many
indirect costs to workers that it is often difficult to measure them. One of the most
obvious indirect costs is the human suffering caused to workers' families, which cannot be
compensated with money.
The costs to employers
of occupational accidents or illnesses are also estimated to be enormous. For a small
business, the cost of even one accident can be a financial disaster. For employers, some
of the direct costs are:
- payment for work not performed;
- medical and compensation payments;
- repair or replacement of damaged machinery and equipment;
- reduction or a temporary halt in production;
- increased training expenses and administration costs;
- possible reduction in the quality of work;
- negative effect on morale in other workers.
Some of the indirect costs
for employers are:
- the injured/ill worker has to be replaced;
- a new worker has to be trained and given time to adjust;
- it takes time before the new worker is producing at the rate of the original worker;
- time must be devoted to obligatory investigations, to the writing of reports and filling out of forms;
- accidents often arouse the concern of fellow workers and influence labour relations in a negative way;
- poor health and safety conditions in the workplace can also result in poor public relations.
Overall, the costs of most
work-related accidents or illnesses to workers and their families and to employers are
very high.
On a national scale, the
estimated costs of occupational accidents and illnesses can be as high as three to four
per cent of a country's gross national product. In reality, no one really knows the total
costs of work-related accidents or diseases because there are a multitude of indirect
costs which are difficult to measure besides the more obvious direct costs.
Health and safety
programmes
For all of the reasons given
above, it is crucial that employers, workers and unions are committed to health and safety
and that:
- workplace hazards are controlled - at the source whenever possible;
- records of any exposure are maintained for many years;
- both workers and employers are informed about health and safety risks in the workplace;
- there is an active and effective health and safety committee that includes both workers and management;
- worker health and safety efforts are ongoing.
Effective workplace health
and safety programmes can help to save the lives of workers by reducing hazards and their
consequences. Health and safety programmes also have positive effects on both worker
morale and productivity, which are important benefits. At the same time, effective
programmes can save employers a great deal of money.

Points to remember |
|
|
In general, health and safety
in the workplace has improved in most industrialized countries over the past 20 to
30 years. However, the situation in developing countries is relatively unclear largely
because of inadequate accident and disease recognition, record-keeping and reporting
mechanisms.
It is estimated that at least
250 million occupational accidents occur every year worldwide. 335,000 of these accidents
are fatal (result in death). (Since many countries do not have accurate record-keeping and
reporting mechanisms, it can be assumed that the real figures are much higher than this.)
The number of fatal accidents is much higher in developing countries than in
industrialized ones. This difference is primarily due to better health and safety
programmes, improved first-aid and medical facilities in the industrialized countries, and
to active participation of workers in the decision-making process on health and safety
issues. Some of the industries with the highest risk of accidents worldwide are: mining,
agriculture, including forestry and logging, and construction.
Identifying the cause of an accident
In some cases, the cause of
an industrial injury is easy to identify. However, very often there is a hidden chain of
events behind the accident which led up to the injury. For example, accidents are often
indirectly caused by negligence on the part of the employer who may not have provided
adequate worker training, or a supplier who gave the wrong information about a product,
etc. The consistently high fatal accident rates in developing countries emphasize the need
for occupational health and safety education programmes that focus on prevention. It is
equally important to promote the development of occupational health services, including
the training of doctors to recognize work-related diseases in the early stages.
Exposure to hazards in the workplace can lead to serious illness. |
 |
 |
- asbestosis (caused by asbestos, which is common in insulation, automobile brake linings, etc.);
- silicosis (caused by silica, which is common in mining, sandblasting, etc.);
- lead poisoning (caused by lead, which is common in battery plants, paint factories, etc.);
- and noise-induced hearing loss (caused by noise, which is common in many workplaces, including airports, and workplaces where noisy machines, such as presses or drills, etc. are used).
There are also a number of
potentially crippling health problems that can be associated with poor working conditions,
including:
- heart disease;
- musculoskeletal disorders such as permanent back injuries or muscle disorders;
- allergies;
- reproductive problems;
- stress-related disorders.
Many developing countries
report only a small number of workers affected by work-related diseases. These numbers
look small for a variety of reasons that include:
- inadequate or non-existent reporting mechanisms;
- a lack of occupational health facilities;
- a lack of health care practitioners who are trained to recognize work-related diseases.
Because of these reasons and
others, it is fair to assume that in reality, the numbers of workers afflicted with
occupational diseases are much higher. In fact, overall, the number of cases and types
of occupational diseases are increasing, not decreasing, in both developing and
industrialized countries.
Identifying the cause of
occupational disease
The cause of work-related
diseases is very often difficult to determine. One factor is the latency period (the fact
that it may take years before the disease produces an obvious effect on the
worker's health). By the time the disease is identified, it may be too late to do anything
about it or to find out what hazards the worker was exposed to in the past. Other factors
such as changing jobs, or personal behaviours (such as smoking tobacco or drinking
alcohol) further increase the difficulty of linking workplace exposures to a disease
outcome.
Although more is understood
now about some occupational hazards than in the past, every year new chemicals and new
technologies are being introduced which present new and often unknown hazards to both
workers and the community. These new and unknown hazards present great challenges to
workers, employers, educators, and scientists, that is to everyone concerned about
workers' health and the effects that hazardous agents have on the environment.
 |
Points to remember about |
|
|
There is an unlimited number
of hazards that can be found in almost any workplace. There are obvious unsafe working
conditions, such as unguarded machinery, slippery floors or inadequate fire precautions,
but there are also a number of categories of insidious hazards (that is, those hazards
that are dangerous but which may not be obvious) including:
- chemical hazards, arising from liquids, solids, dusts, fumes, vapours and gases;
- physical hazards, such as noise, vibration, unsatisfactory lighting, radiation and extreme temperatures;
- biological hazards, such as bacteria, viruses, infectious waste and infestations;
- psychological hazards resulting from stress and strain;
- hazards associated with the non-application of ergonomic principles, for example badly designed machinery, mechanical devices and tools used by workers, improper seating and workstation design, or poorly designed work practices.
Hazards are often built into workplace. |
 |
Work processes can be designed to prevent accidents and illnesses. Existing hazards should be removed from the workplace. |
 |
Workers do not create hazards
- in many cases the hazards are built into the workplace. The trade union position on
occupational health and safety is to ensure that work is made safer by modifying the
workplace and any unsafe work processes. This means that the solution is to remove the
hazards, not to try to get workers to adapt to unsafe conditions. Requiring workers to
wear protective clothing which may not be suited or designed for the climate of your
region is an example of forcing workers to try to adapt themselves to unsafe conditions,
which is also shifting the responsibility from management to the worker.
It is important for unions to
maintain this position because many employers blame workers when there is an accident,
claiming that the workers were careless. This attitude implies that work can be made safer
if workers change their behaviour or if employers only hire workers who never make
mistakes. Everyone makes mistakes — it is human nature, but workers should not pay
for mistakes with their lives. Accidents do not stop simply by making workers more safety
conscious. Safety awareness may help but it does not remove unsafe work processes or
conditions. The most effective accident and disease prevention begins when work
processes are still in the design stage, when safe conditions can be built into the work
process.
 |
Points to remember |
|
|
A successful health and safety programme requires strong management commitment and worker participation. |
 |
In order to develop a
successful health and safety programme, it is essential that there be strong management
commitment and strong worker participation in the effort to create and maintain a safe and
healthy workplace. An effective management addresses all work-related hazards, not only
those covered by government standards.
All levels of management must
make health and safety a priority. They must communicate this by going out into the
worksite to talk with workers about their concerns and to observe work procedures and
equipment. In each workplace, the lines of responsibility from top to bottom need to be
clear, and workers should know who is responsible for different health and safety issues.
 |
Points to remember
about the importance of management commitment
|
|
|
Effective training is a key component of any health and safety programme. |
 |
Workers often experience
work-related health problems and do not realize that the problems are related to their
work, particularly when an occupational disease, for example, is in the early stages.
Besides the other more obvious benefits of training, such as skills development, hazard
recognition, etc., a comprehensive training programme in each workplace will help workers
to:
- recognize early signs/symptoms of any potential occupational diseases before they become permanent conditions;
- assess their work environment;
- insist that management make changes before hazardous conditions can develop.

A
comprehensive health and safety training programme in each workplace will, among other
more obvious benefits, help workers to recognize any early signs/symptoms of potential
occupational diseases before they become permanent conditions, to assess their work
environment, and to insist that management make changes before hazardous conditions can
develop.
|
Health and safety representative |
 |
As health and safety
representative your role is to work proactively (this means taking action before
hazards become a problem) to prevent workers from being exposed to occupational hazards.
You can do this by making sure management eliminates hazards or keeps them under control
when they cannot be eliminated.
Steps to help you reach your
goals are:
1. Be well informed about the
various hazards in your workplace and the possible solutions for controlling those
hazards.
2. Work together with your
union and the employer to identify and control hazards.
3. Although these Modules
have been developed for the protection of workers, you may occasionally need to share some
of this information with your supervisors and employer in the process of working towards a
safe and healthy workplace.
Being a health and safety
representative is not always easy, but helping to protect the lives of your fellow workers
is worth all the time and effort you put into the job.
Use a variety of sources for information about potential or existing hazards in your workplace. |
 |
 |
Workers in
every occupation can be faced with a multitude of hazards in the workplace. Occupational
health and safety addresses the broad range of workplace hazards from accident prevention
to the more insidious hazards including toxic fumes, dust, noise, heat, stress, etc.
Preventing work-related diseases and accidents must be the goal of occupational health and
safety programmes, rather than attempting to solve problems after they have already
developed.
Hazards in the workplace can
be found in a variety of forms, including chemical, physical, biological, psychological,
non-application of ergonomic principles, etc. Because of the multitude of hazards in most
workplaces and the overall lack of attention given to health and safety by many employers,
work-related accidents and diseases continue to be serious problems in all parts of the
world. Therefore, trade unions must insist that employers control hazards at the source
and not force workers to adapt to unsafe conditions.
Management commitment to
health and safety and strong worker participation are two essential elements of any
successful workplace health and safety programme. The most effective accident and disease
prevention begins when work processes are still in the design stage.

Note to
the instructor
For this exercise, ask
trainees to work in small groups of two to three people. Give several of the pictures in
your text to each group. You will also need a flipchart (or some large sheets of paper
taped to the walls) and markers or a chalkboard and chalks.
Instructions
The pictures below show
different workplaces where a variety of hazards can be found. Ask trainees to look at the
pictures and imagine what sort of problems might exist in each workplace. Write the
trainees' responses for each workplace on a flipchart or chalkboard. Some of the major
hazards associated with each of these jobs are given below.
When you finish discussing
the jobs shown in the pictures, discuss the hazards in the trainees' own workplaces.
Trainees should discuss the questions listed in the section “In you own
workplace” below.
|
Discuss the hazards that
may be associated with these jobs
1. Welder — A welder can
be burnt from the sparks and there is always the danger of the work process starting a
fire. There is the problem of the intense light which can cause permanent eye damage as
well as the fumes given off by the process which can damage the lungs.
2. Mechanic - Depending on
the precise nature of a mechanic's duties, there may be safety problems from cuts and
falls, etc., and exposure to chemical hazards: oils, solvents, asbestos and exhaust fumes.
Mechanics can also have back and other musculoskeletal problems from lifting heavy parts
or bending for long periods.
3. Port worker - Again
hazards depend largely on the nature of the job and in particular the cargo being handled.
Port workers often have no idea of the dangerous nature of the cargo; there may be a sign
on the side of a box or drum, but the information may not be in their language or in words
that make much sense to the average worker. The condition of the cargo is also important
as leaking drums or split bags can be very hazardous for the handlers. Other risks include
falls, cuts, back and other musculoskeletal problems as well as collisions with fast
moving vehicles such as fork-lift trucks or delivery trucks.
4. Textile worker - The
textile worker faces a variety of problems. First there is the problem of safety with many
machines around that are often unguarded, as well as the risk of fire with so much
combustible material in the workplace. Then there are the hazards of noise and vibration.
There is also exposure to dust from the material which can seriously affect the lungs.
Exposure to cotton dust can lead to the occupational disease known as byssinosis.
5. Tractor driver - One of
the most serious problems with tractors is that they often overturn and, if they have no
safety cab, the driver can easily be crushed. Other problems include noise, vibration and
exposure to chemical herbicides and pesticides when being sprayed by tractor.
6. Agricultural worker - When
spraying crops the worker may be exposed to hazardous chemicals contained in the spray.
Many pesticides and herbicides that have been banned in some countries because of their
toxic effects are still used in many developing countries. If spraying takes place on a
windy day, the spray can be breathed into the lungs and blown on to the skin where it can
cause damage. It can also be absorbed into the body through the skin.
7. Electronics assembly
worker - An electronics assembly worker can suffer eye problems from doing close work,
often in poor light. Because such workers sit still for long periods with inadequate
seating, they can also suffer from back and other musculoskeletal problems. For some
workers there are the dangers of solder fumes or solder “flecks” in the eye when
the excess solder is cut off with pliers.
8. Office worker - Many
people may think that office workers have no health and safety problems; this is far from
true. Stress is one of the most common complaints, as well as exposure to chemical hazards
from office machines such as photocopiers. Poor lighting, noise and poorly designed chairs
and stools can also present problems.
9. Construction worker -
Construction workers face a variety of hazards, particularly safety problems such as
falls, slips, trips, cuts, and being hit by falling objects. There are also dangers from
working high up, often without adequate safety equipment, musculoskeletal problems from
lifting heavy objects, as well as the hazards associated with exposure to noisy machinery.
10. Miner - The hazards of
mining are well known and include the ever present danger of dusts, fire, explosion and
electrocution, as well as the hazards associated with vibration, extreme temperatures,
noise, slips, falls, cuts, etc.

Note to the instructor
Now that trainees have begun
to consider the possible hazards in different workplaces, ask them to consider and discuss
the hazards in their own workplaces. Trainees should answer the following questions about
their own workplaces.
(1) Describe the job you do.
(2) What hazards do you know
exist in you workplace?
(3) Are there other
conditions at work that you suspect may be hazardous but you are not sure about?
