What is the Difference Between PELs and Other Exposure Limits?
PELs are just one type of occupational exposure limit. Other types include Threshold Limit Values (TLVs), published by the American Conference of Governmental Industrial Hygienists (ACGIH), and Recommended Exposure Limits (RELs), proposed by the National Institute for Occupational Safety and Health (NIOSH). While PELs have legal standing, TLVs and RELs serve as guidelines based on the latest scientific research. Each type of limit may vary for the same substance, reflecting different perspectives on acceptable risk levels and protective measures.
