The joint international labor organization committee on Occupational health, 1950 defined occupational health as “The highest degree of physical, mental and social well-being of workers in all occupations.”

DEFINITION: DEFINITION:

GOALSGOALS

• To reduce industrial accidents.

• To prevent occupational hazards/ diseases.

• To achieve maximum human efficiency and machine efficiency.

• To reduce sick absenteeism.

OBJECTIVES OF OBJECTIVES OF OCCUPATIONAL HEALTH:OCCUPATIONAL HEALTH:

• To maintain and promote the physical, mental and social well being of the workers.

•   To prevent occupational diseases and injuries.

•   To adapt the work place and work environment to the needs of the workers i.e application of ergonomics principle.

• It should be preventive rather than curative.

It represents a dynamic equilibrium between the worker and his occupational environment.
