American Conference of Governmental and Industrial Hygienists

The American Conference of Governmental Industrial Hygienists (ACGIH) is a professional organization that sets recommended guidelines to protect workers from health hazards like chemicals, dust, and noise in the workplace. They evaluate scientific data to establish exposure limits, called Threshold Limit Values (TLVs), which help employers and safety professionals create safe work environments. Although these recommendations are not legally binding, they are widely respected and used to promote occupational health and safety standards across various industries.
