Which statement is true about occupational exposure limits?

• A. They are used to protect workers from overexposure to hazards.
• B. They specify the exact dose that will injure every worker.
• C. They are not used in decision making.
• D. They apply only to biological hazards.

Answer: (A)

Occupational exposure limits are numeric thresholds that set safe exposure levels for hazards in the workplace and are used to prevent overexposure. They provide decision-making benchmarks for monitoring, engineering controls, and protective equipment, helping to keep actual exposures below these limits. They are not a guaranteed dose that will injure every worker—individual sensitivity, duration of exposure, and the combination of hazards mean health effects can occur at different levels for different people. They cover a range of hazards, primarily chemicals and particulates, and while some guidance exists for biological agents, the concept is not limited to biology.
