3. INTRODUCTION
Occupational health is an important branch in community health.
Previously it was thought that its entirely related to factories and mines.
Hence the term “industrial health” and “industrial hygiene” were
common. Now the concept was changed according to concept in the
society/community. Modern concept of “occupational health” now
embraces all types of employment including mercantile and commercial
enterprises, service traders, forestry, agricultural and various other
sectors.

4. DEFINITION
Occupational health is defined in the occupational health and safety
encyclopedia as being concerned with physical, mental & social
wellbeing of man in relation to his work & working environment, his
adjustment to work & adjustment of work to man.
- Forsman(1976)
Occupational health is the branch of medicine dealing with the
prevention and treatment of job related injuries & illness.
- Oxford dictionary

5. AIMS
Promotion and maintenance of high degree of physical, mental &
social wellbeing of workers in all occupation.
Prevention among workers of the departures from health caused by
their working condition.
Protection of workers in their employment from risks resulting from
factors adverse to health.

6. AIMS….
Placing & maintenance of workers in an occupational
environment.
To summarize the adaptation of work to man of each man to
his job.
Joint ILO & WHO committee

7. OBJECTIVES
Promote & maintain highest degree of possible health.
Prevent health declination.
Protect from adverse factors.
Assist the injured & disabled for rehabilitation.

8. Ergonomics
• Ergonomics is the study of men at work
with a view to identify stress factors
operating in work environments and
impairing the physical, mental and
psychological health of workers and
interfering with their work performance.

• Dusts are finely divided solid particles with size ranging from
• 0.1 to 150 microns
• Dust particles larger than 10 microns settle down from the air
rapidly,
• Indefinitely Particles smaller than 5 microns are directly inhaled
into the lungs and are retained there and is mainly responsible for
pneumoconiosis.

26. Classification of dusts

health hazard producing, after a variable period of exposure,
a lung disease known as pneumoconiosis, which may
gradually cripple a man by reducing his work capacity due to
lung fibrosis and other complications.

84. JOURNALABSTRACT
• OCCUPATIONAL HEALTH AND SAFETY IN INDUSTRIES IN
DEVELOPING WORLD
Iftikhar Ahmad1, Abdul Sattar2, Allah Nawaz2 1Department of Community
Medicine, Gomal Medical College, 2Department of Public Administration, Gomal
University, Dera Ismail Khan, Pakistan. ABSTRACT: Current global workforce
stands at about 2.8 billion. Workers spend about one third of their lifetime at
workplace. Workers expect safe working environment as their fundamental human
right. However there are still poor working conditions especially in developing
countries due to lack of practicing simple preventive measures.

85. • The standard of Occupational health and safety available at any work place is
the main determinant of workers’ health. Workers all over the world, face dual
occupational hazards, the traditional as well as novel in the complex work
settings due to rapid industrialization, technological advancement and
globalization, over the last few years. An equally wide variety of chemical,
physical and psychological hazards in production. Occupational health issues
affect individuals, families and communities, as well as the citizens of the
world. All the stake holders including the state, the manager, the employer and
the worker have certain responsibilities to take up medical, engineering and
legislative interventions to make work environment safer.

86. CONCLUSION
Occupational disease not been
neglected and should give proper
attention at time. It’s the main role
of a nurse to work as an educator
and protector in the field of
occupation.
