Wheele Oofo September 7, 1972 Origmafinp Dipt. Antwring Utttr dot* 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. 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 and combustible level inside autoclave before entering, (1) 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. ucc 064963 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. BLM/us ucc 064964 master tag no.
