Information from exposure monitoring and health surveillance programmes should be used to judge how effective processes and controls such as ventilation or hearing protection are, and to find out exposure levels before workers are harmed. It should compare exposures with established OH&S criteria to see whether levels are exceeded, use health surveillance to detect signs or symptoms of ill health, and measure and monitor exposure to chemical, biological, physical, psychosocial and ergonomic health hazards. Because the effects of exposure can take months or years to appear as symptoms, it should combine health surveillance data with exposure assessment data, and it can add information from workers, including vulnerable groups such as pregnant women and disabled workers, and from surveys to evaluate control effectiveness and find improvements. The confidentiality of personal health surveillance data should be protected.
