Exposure monitoring analyzes hazardous substances in the air or on surfaces of a workplace, and is complementary to biomonitoring, which instead analyzes toxicants or their effects within workers. A wide array of methods and instrumentation are used in workplace exposure monitoring.
Requests should also be made when employees are exposed to a new hazard or a hazard unregulated by OSHA or when employees are experiencing ill health when their exposure to an agent is below the occupational exposure limits. If multiple hazardous agents or conditions are present in the workplace, an HHE request can be beneficial. Common hazards ...
HAZWOPER applies to five groups of employers and their employees.
