Threshold Limit Values (TLVs) refer to airborne concentrations of chemical substances and represent conditions under which it is believed that nearly all workers may be repeatedly exposed, day after day, over a working lifetime, without adverse effects. They are OSHA-recommended occupational exposure limits issued by the American Conference of Governmental Industrial Hygienists (ACGIH).
ACGIH has established the Threshold Limit Values (TLVs) for over 600 chemical substances and physical agents, as well as over 30 Biological Exposure Indices for selected chemicals. Many authorities have referred to ACGIH TLVs when setting occupational exposure limits in their own jurisdictions.
It shall be noted that other occupational exposure limits (OELs) are also used in the United States.They shall be included in SDSs if available.
