How can the risks posed by health hazards be controlled?
The best methods of controlling exposure to a particular hazard will depend on what it is. In general, methods of control can be placed in four categories: • Engineering controls are methods of designing or modifying plants, processes and equipment so as to minimize workers’ exposure to the hazard. They are preferred because they work independently of workers. • Work and hygiene practices are on-the-job activities that reduce the potential for exposure. • Administrative controls are things like job rotation schedules, work-rest cycles and timing of maintenance procedures, which can be used to limit the amount of time an individual is exposed to a hazard. • Personal protective equipment includes items like respirators, hearing protectors, safety clothing and protective clothing. It can reduce a worker’s exposure but must be used properly to be effective.
