S. H. A.) announced the Permanent Vinyl Chloride Health Standard for reducing worker exposure to vinyl chloride monomer. In accordance with this action, we have revised the Material^S.afety Data, Sheets for our Geon vinyl chloride latexes. We are enclosing revised Material Safety Data Sheets to be noted and used in place of those which, according to our records, were sent to you previously. Also enclosed is a copy of our L-13 Bulletin, Handling and Storing Latexes, and a copy of a January 6, 1975, letter from Mr. R. L. Steller, Product Director of Latex and Specialty Chemicals. The letter describes the current situation with respect to residual vinyl chloride monomer contained in our Geon vinyl chloride latexes. Please let us know if there are questions. crw Enclosures Sincerely, LA Robert L. Spencer, Technical Service Manager - Latex / /. P 2?. 12 .

Self-contained breathing apparatus should be used in closed areas such as warehouses. Unusual Fire and Explosion Hazards NOTE: Vinyl chloride monomer is explosive in a range of 4% to 22% by volume in air. See page 7 of L-13 Bulletin. Our vinyl latexes are stripped of residual monomer to less than 0.01% by weight (on latex solids weight). At the specification maximum of 0.01% residual monomer, an explosive level cannot be attained in the vapor space of a closed vessel at normal latex storage temperatures. See pages 1 and 5 of L-13 Bulletin for our reccrnmanded storage temperatures. All storage tanks should be vented to the outside. SECTION V - HEALTH HAZARD DATA Threshold Limit va2ue See 0. S. H. A. Chapter XVII, Part 1910, Federal Register, Volume 39, No. 194 (10-4-74) and addendum attached. The proposed T.L.V. for vinylidene chloride moncmer is 10 ppm (American Conference of Governmental Industrial Hygienists 1974). Effects of Overexposure Vxnyl chloride/vinyLidene chloride/acrylic latex contains vinyl chloride rconcxner. a cancer-suspect agent. Open, handle, and use under well-ventilated conditions. Refer to 0. S, H. A. regulation above. The latex contains residual vinylidene chloride ironorner. In 1974, the American Conference of Governmental Industrial Hygienists proposed a T.L.V. of 10 ppm. In October, 1974, reports were received from Europe that exposure of Wistar rats to high concentrations of vinylidene chloride rroncmer resulted in seme increased incidence of abdominal tumors. Farther experimental testing is being initiated both in Europe and U. S. A. Liquid contact with eyes may cause irritation. Einergencu and First Aid Procedures 1. DO NOT INGEST - If ingested, contact physician.* 2. AVOID SKIN CONTACT - Wash thoroughly with cold water any part of the body which comes in contact with latex.

A.) announced the Permanent Vinyl Chloride Health Standard (Title 29 - Labor, Chapter XVII, Part 1910) for reducing worker exposure to vinyl chloride monomer. The standard is detailed in the Federal Register, Volume 39, Number 194, October 4, 1974, pages 35890-35898. As polyvinyl chloride latex is manufactured in the industry today, detectable quantities of vinyl chloride monomer remain in the product. While this may not result in detectable quantities in the general atmosphere in your plant, there are conditions under which residual monomer nay accumulate to measurable amounts. It is the intent of this addendum to indicate the order of magnitude of the trace amounts of residual vinyl chloride monomer presently in our products at the time of manufacture and to point out potential areas of accumulation. Geon latexes contain a maximum of 0.01% (based on latex solids weight) of vinyl chloride monomer. We are working diligently to reduce these trace amounts and progress is constantly being made. Since vinyl chloride monomer is volatile, it is released from the latex gradually in storage and more rapidly under heat of drying and further processing. In all cases, Geon latexes should be opened, handled, and used under well-ventilated conditions. Refer to 0. S. H. A. Standard for details. are: Analysis has shown that areas where vinyl monomer might concentrate (1) In enclosed vessels such as bulk; railcars, bulk trucks, storage tanks, and drums. The air space above the latex should be purged and monitored for vinyl monomer or adequate protection provided prior to exposure of personnel. (2) In processing areas such as compound preparation, spraying, or coating. Suitable ventilation should be provided. (3) In drying and curing areas. Normal good operating practice in exhausting volatiles nay be sufficient. The concentration of vinyl chloride monomer at the mandated exposure limits cannot be detected by cdor so that suitable test equipment and methods must be used as indicated. Intense technical efforts by us are resulting in a rapidly changing situation. As additional information becomes available, we shall keep you informed. AP00031077
