The prevention of occupational illness is based on three levels. Primary measures
are aimed at preventing the occurrence of disease by eliminating or reducing exposure to occupational hazards which include the following:
• The testing of chemicals prior to their use and substitution of chemicals by less
hazardous chemicals
• Control of hazardous exposure by engineering measures
• Assessments of the hygiene of the workplace
• Worker placement and training
• Use of appropriate protective equipment
At a secondary level, efforts are made to detect sickness at an early stage prior to
the onset of clinical signs as well as symptoms. At this stage, the progress of the
sickness may be slowed/halted/reversed.
The tertiary level of avoidance involves the suitable treatment of any diagnosed
medical condition to minimize the effects of ailment or disability to enable a return
to productive employment.
First Aid
First aid is the first help provided to any person suffering injury/illness to prevent
the condition from deterioration, or to promote recovery from situations that include:
• Injury
• Poisoning
• Burns and scalds
