Vinyl Chloride Exposure Limits

Exposure to vinyl chloride is also subject to workplace safety standards for airborne concentrations.

Chloroethene chloroethylene ethylene monochloride monochloroethene monochloroethylene vc vcm vinyl chloride monomer vcm colorless gas or liquid below 7 f with a pleasant odor at high concentrations. The us epa and fda limit vinyl chloride in drinking water to 0 002 ppm.

Recent improvements to manufacturing processes have substantially reduced the levels of residual vinyl chloride in pvc products. The us osha limits vinyl chloride exposure of workers to no more than 1 ppm for eight hours or 5 ppm for 15 minutes. Exposure to vinyl chloride from food and beverage consumption is estimated at 0 1 µg day. 1 no employee may be exposed to vinyl chloride at concentrations greater than 1 ppm averaged over any 8 hour period and 2 no employee may be exposed to vinyl chloride at concentrations greater than 5 ppm averaged over any period not exceeding 15 minutes.

The food and drug administration currently limits the quantity of vinyl chloride in food contact plastics. Explosive polymerization may occur at elevated temperatures if vinyl chloride is not inhibited. Vinyl chloride is treated as a human carcinogen. The monomer of vinyl chloride.

C permissible exposure limit. Shipped as a liquefied compressed gas. In the 1970s residual vinyl chloride was found in products such as vinyl music records plastic food bottles kitchen wrapping films and bathroom tiles. Osha pel permissible exposure limit 1 ppm averaged over an 8 hour workshift niosh idlh immediately dangerous to life or health not yet determined.

Occupational safety health administration provides information about exposure limits to vinyl chloride. Agency for toxic substances and disease registry. Niosh recommends that the exposure limit for a time weighted average twa for vinyl chloride in air be the lowest reliably detectable concentration. Hazardous operation means any operation procedure or activity where a release of either vinyl chloride liquid or gas might be expected as a consequence of the operation or because of an accident in the operation which would result in an employee exposure in excess of the permissible exposure limit.

The legal airborne permissible exposure limit pel is 1 ppm averaged over an 8 hour workshift and 5 ppm. No employee may be exposed to vinyl chloride at levels greater than 1 ppm averaged over any 8 hour period or levels greater than 5 ppm averaged over any period exceeding 15 minutes. Pvc consumer products may contain very small residual amounts of vinyl chloride. Vinyl chloride is flammable and reactive and a dangerous fire and explosion hazard.
