Who publishes PELs?

Who publishes PELs?

• A. NIOSH publishes PELs.
• B. ACGIH publishes PELs.
• C. EPA publishes PELs.
• D. OSHA publishes PELs.

Answer: (D)

PEL stands for permissible exposure limit, and in the United States these limits are published by OSHA. OSHA sets legally enforceable exposure limits for hazardous substances, typically expressed as an 8‑hour time-weighted average or a short-term exposure limit, and these appear in OSHA standards. Employers must ensure worker exposures stay at or below these PELs, or face enforcement actions. ACGIH provides TLVs, which are voluntary guidance used by many professionals but not enforceable by law. NIOSH issues RELs as recommendations for guidance, not regulatory limits unless OSHA adopts them as PELs. EPA handles environmental exposure limits in settings like air and water outside of workplace regulations.
