The dynamics of accidents and illnesses at the work place can be understood from
some basic concepts namely: relationship between work and health; the worker with
his pre-existent health status enters into a work place. Factors that influence around
him while at work are hazards which are physical, chemical, biological and
ergonomic in nature. The workers protective mechanism that is available is the
relevant regulations and relevant policies that are in place; with this in mind the focus
of occupational health becomes three pronged; health promotion and maintenance of
the highest degree of physical, mental and social well being of all workers;
prevention of adverse health effects due to work; and, improving working
environment and work to become conducive to health and safety.
