To achieve maximum human efficiency and machine efficiency.
To reduce sick absenteeism.

4. OBJECTIVES OF 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.
