TLVs (Threshold Limit Values) are subject to periodic updating or changes as published by the American Council of Governmental Industrial Hygienists (ACGIH). PELs (Permissible Exposure Limits) are set by OSHA and may also be subject to periodic updates, but not by ACGIH. Als (Action Levels) and STELs (Short-Term Exposure Limits) are specific types of limit values and are not updated by ACGIH.
