Recommended Exposure Limits (RELs) are provided by which agency?

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

Answer: (C)

The main concept is identifying who publishes Recommended Exposure Limits for occupational hazards. RELs are provided by NIOSH—the National Institute for Occupational Safety and Health, which is part of the U.S. Centers for Disease Control and Prevention. RELs are health-based guidance intended to help protect workers by suggesting exposure levels to aim for. They are not legally enforceable standards; that role belongs to OSHA, which sets enforceable Permissible Exposure Limits. Other organizations, like ACGIH, publish TLVs as guidelines used by some professionals, and the EPA handles environmental risk standards. So, RELs come from NIOSH.
