Who recommends the exposure limit?

• A. OSHA
• B. EPA
• C. DoD
• D. NIOSH

Answer: (D)

Exposure limits are guidance built from careful review of health effects and hazard data to keep workers safe. The agency that establishes and publishes these recommended exposure limits is NIOSH. They research hazards, evaluate data on how much of a substance or condition people can be exposed to without harm, and issue RELs (recommended exposure limits) accordingly. OSHA, by contrast, enforces enforceable limits in workplaces, often drawing on NIOSH findings when setting its PELs, but its primary role is enforcement rather than making recommendations. EPA focuses on environmental exposure standards, not routine workplace limits, and DoD sets safety practices within the military context. So, the entity that directly recommends exposure limits is NIOSH.
