It is an undisputed fact that every work is associated with one or more hazards to safety and health.
Hazards differ, and so do their effects.
Workers may also be exposed to biological hazards, such as viruses, bacteria, fungi, etc., depending on their work settings. All of these hazards pose risks to workers. Risk surveys are normally carried out to address these hazards. Risk can be defined as the degree of exposure to hazards that would cause occupational accidents or occupational health problems. Further, it would be logical to devise alternative strategies for controlling the risks, and hence for controlling their impact on the enterprise.
