OSHA decides not to go with TLVs as its standard for exposure to chemicals

OSHA is getting ready to abandon its proposal to use Threshold Limit Values (TLVs) as its standard for exposure limits to chemicals.

OSHA recently decided to maintain its mandatory permissible exposure limits (PELs), rather than switch to the TLVs, designed by the American Conference of Governmental Industrial Hygienists.

Critics of the TLVs have contended that they were scientifically invalid and developed in a way that did not allow sufficient outside input.
