True or False: A TLV® is a regulatory exposure limit set specifically by OSHA.

A TLV® (Threshold Limit Value) is not a regulatory exposure limit set by OSHA (Occupational Safety and Health Administration); rather, it is a guideline established by the American Conference of Governmental and Industrial Hygienists (ACGIH). TLVs are intended to assist in the control of health hazards in the workplace and are based on scientific research and expert judgment regarding exposure levels that are believed to be safe for most workers. While OSHA does set legally enforceable limits known as permissible exposure limits (PELs), TLVs are recommendations that may influence workplace practices but do not have the force of law. Thus, stating that a TLV® is a regulatory exposure limit set specifically by OSHA is incorrect.
