The Department of Labor, Occupational Safety and Health Ad ministration (OSHA), has proposed new standards to limit ex posure to vinyl chloride monomer (VCM). This regulation is of concern to plants manufacturing VCM and/or polyvinyl chloride (PVC) and plants which process PVC into compounds and/or fabricated products. The regulation has been devised in order to limit exposure to VCM, as it has been suspected of being linked to the incidence of angiosarcoma. Other governmental agencies, such as the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA) are also interested in this problem. The Society of Plastics Engineers, Inc. has scheduled a two day technical conference in order to disseminate informa tion relative to the new regulation, emphasizing the effect on the PVC processor. This RETEC will feature.......... History of the VCM situation relative to its effect on em ployee health. A summary of OSHA, FDA and EPA regulations, current and proposed. Explanation of what the regulations mean to producers, processors and users of vinyl plastic products, Analytical devices and methods of detection and monitoring. Protective equipment. Processing techniques to minimize VCM exposure, Analysis of future needs. Educational displays pertinent to the technical papers. EDUCATIONAL DISPLAYS -- Versailles Terrace Flours: Thursday, Oct. 31 -- 10:00 a.m. -- 12:15 p.m. 2:00 p.m. - 6:00 p.m. Friday, Nov. 1 -- 10:00 a.m. -- 12:15 p.m. 2:00 p.m. -- 4:00 p.m. Nature of the Educational Displays will consist of companies supplying equipment for the detection of VCM, protective equipment from VCM exposure, as well as consulting, engin eering and analytical sSrvices relative to VCM. Detection equip ment includes spot and continuous analyzers based on gas chromatography, infrared and colorimetric techniques. For further information, contact E. J. Wickson, Exxon Chemical Co. P.O.

Mantcll * 8:45 a.m. "Monitoring Ambient Vinyl Chloride with In frared Analyzers". Paul A. Wilke, Jr., President Donald S. Lavery /' Wilks Scientific Corporation Abstract: VCM has a characteristic infrared spectrum. Thus, with recently developed selective filter infrared analyzers equip ped with long-path absorption cells, it can be detected in the atmosphere and measured quantitatively in the low parts per million range. The infrared method has high specificity, provides nearly instantaneous measurements and the equipment is simple, requiring a minimum of service and maintenance. Both portable and continuous, multi-sample point infrared VCM analyzers will be described.. 9:15 a.m. "A Continuous Monitor for Vinyl Chloride Monomer, Based Upon an Impregnated, Paper Tape", Byron A. Denenberg, Vice-President MDA Scientific, Inc. Abstract; A self-contained, specific, low-cost, semi-portable, continuous monitor for VCM has been developed. Model 7070 is based upon the use of an impregnated paper tape, supplied in convenient cassettes which produces a color reaction when ex posed to VCM. Continuous recording and both audio and visual alarms are incorporated into the basic design. The monitor and the color reactions will be discussed. 9:45 a.m. "VCM -- What to Expect During an OSHA In spection" Otto White, Jr,, Regional Industrial Hygienist U.S. Department of Labor Occupational Safety and Health Administration New York, N. Y. Abstract: An in-depth view of the typical procedures utilized during an OSHA inspection to determine compliance to the Vinyl Chloride Standard, 29 CFR 1910.93q. Discussion in cludes: recogriTtion and identification of potential vinyl chloride sources, review of vinyl chloride monitoring program and records, evaluation of control methods used to limit airborne concentration of vinyl chloride, assessment of respiratory pro tection program and extent of employees knowledge in relation to exposures in excess of the standard and observation of monitoring. 10:15 a.m. Coffee Break 10:30 a.m. 11:15 a.m. PANEL SESSION: Discussion of questions rela tive to VCM: Sample Collection and analysis.
