LM6 Revised 10-15*76 Methods of Compliance to the Permissible Exposure Limits OSHA Regulation 1910.93 q - Standard for Exposure to VC1 8FG Technical Center OSHA regulation 1910,93d requires that employee exposures to vinyl chloride shall be controlled to 1 ppm or less of-VC! averaged over any 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 arc 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.

Made canvas hoods for containing vapors from leaky valves & gaskets. Installed bench hood for matr. work up. This job is essentially conolete. Stack has been approved for Hydrin. The Geon Vsclets will be tied into this stack. Design is on HOLD. Working on improving performance of existing heating system at a cost of $23,000. No action. Budget estimate complete. Using post polymer ization plus high pressure condensation (4or). Working on layout and detail designs. Completion of first nhase olanned for second Quarter. 1977. 1nsta1 lacion of two new 55 1> ter polys with . blow down tanks and stripping and drying system. 10% complete. Reactors received. Process engineers are seeking a better definition of the orocess. EA approved and shop work started. Starting up In fourth quarter of 1976. Completed. 20% complete. ON HOLD. : Continuing a. Increased number of sampling points to 10. Also tied In wind direction & velocity to area monitoring program. b. Lab GC has been placed on hold because of an insufficient number of erroneous excursions. ! We have not been centrifuging. Centrifuge has been removed from VCM building.
