4/1/75 Methods of Compliance to the Permissible Exposure Limits OSHA Regulation 1910.93 q - Standard for Exposure to VC1 BFG Technical Center OSHA regulation 1910.93q requires that employee exposures to vinyl chloride shall be controlled to l ppm or less of VC1 averaged over arty 8 hour period and that no employee shall be exposed to vinyl chloride at concentrations greater than 5 ppm averaged over any period not exceeding 15 minutes. If exposures are above this, feasible engineering and work practice controls shall immediately be used to reduce exposures to at or below the permissible exposure limits. At the Technical Center we have on going programs in both the engineering and process departments. Written plans for these programs are attached and will be furnished upon request for examination and copying to authorized representatives of the assistant Secretary of Labor and the Director of OSHA. These plans will be updated at least every six months. These plans will also be shown to employees who are exposed in excess of the permissible exposure limits to show them the steps being taken to reduce their exposure to within the permissible exposure limits.
