Wheeler* Dai September 7, 1972 Originating Dipt. Attimring hlbr data Subject Dear Don: It was a pleasure to discuss with you by telephone our Environmental Health Program for monitoring vinyl chloride exposures at the South Charleston plant. I As you requested, attached is the calibration curve of J & W Model 55-P Serial No. 7055234 - calibrated on vinyl chloride 6/15/71. Presently, the monitoring program for vinly chloride consists of the following procedures. 1. Air dry and water wash autoclaves, (wash with high pressure water then purge for 1-2 hrs), before entering. 2. Instigate Master Tag Out Procedure(attached). 3. Issue Hazardous Work Permit (attached). 4. Detect oxygen concentration a*id combustible level inside autoclave before entering. (I) 5. Detect vinyl chloride concentration(toxicity) inside autoclave with drager gas detector. (2) , To detect lower concentrations (< lOOppm) of vinyl chloride vapor in the working environment. We use the Analytical Instrument Development, Inc. (AID) portable. uoc 011141 1. No. 505-150-Model GPK - Johnson & Williams Combined Oxygen/ Combustible Gas Indicating Detector. 2. 19/31 - Drager Multi-Gas Detector with No. 100/a Vinyl Chloride Detector Tube. (100-3, OOOppm) .Chromatograph. This instrument is capable of detecting vinyl chloride concentrations in the parts per billion range. Very truly yours, B. L.
