Vehicle B. Solvents C. Heavy Metals D. 7apors SECTION II - HAZARDOUS INGREDIENTS The latex is a uniform, synthetic anionic, colloidal dispersion of a high-nolecular-weight copolymer in water. The latex contains no photochemically-reactive solvents -- no volatile organic solvents of any kind. We do not utilize lead, mercury, or any other heavy metal or heavy metal compound in the manufacture of our vinyl chloride/vinylidene chloride/acrylic latexes. Hdwever, due to the ubiquitous nature of these materials, trace quantities (ppn or ppb) can probably be found by using modem analytical techniques. 1. Vinyl chloride/vinylidene chloride/acrylic latex contains residual vinyl chloride rroncsner, a cancersuspect agent. Refer to Section V and addendum attached. 2. The latex contains residual vinyl idene chloride monomer. Vinylidene chloride rroncmer is not as volatile as vinyl chloride rroncmer, but it can be vaporized at elevated temperatures. The proposed T.L.V. for vinylidene chloride is 10 ppm (American Conference of Governmental Industrial Hygienists - 1974). Refer to Section V. 3. The latex is free of sulfur dioxides and oxides of nitrogen. Nor would these materials be expected to be produced during typical drying operations. Water is the primary volatile material given off during the drying cycle. AP00034581 SECTION III - PHYSICIAL DATA Bolling Point fP.; Water - 212UF.

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. Ckir 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 moncmer, 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 recanmended storage temperatures. All storage tanks should be vented to the outside. SECTION V - HEALTHHAZARDDATA Threshold Limit Value 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 monomer is 10 ppm (American Conference of Governmental Industrial Hygienists 1974). Effects of Overexposure vinyl chloride/vinylidene chloride/acrylic latex contains vinyl chloride monaner. a cancer-suspect agent. Open, harrlle, and use under well-ventilated conditions. Refer to O. S. H. h. regulation above. The latex contains residual vinylidene chloride monomer. 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 monccner resulted in sane increased incidence of abdominal tumors. Further experimental testing is being initiated both in Europe and U. S. A. Liquid contact with eyes may cause irritation. Emergency 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 cares in contact with latex. AP00034582 Emergency and First Aid Procedures (continued) 3. AVOID EYE CONTACT - Immediately flush eyes with water for at least 15 minutes. Contact physician.* *NOTE: ihe pH of the latex should be given to the attending physician.

A.) announced the Penranent Vinyl Chloride Health Standard (Title 29 - Labor, Chapter XVII, Part 1910) for reducing worker exposure to vinyl chloride monccner. Hie 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 sure conditions under which residual monomer may 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 ncncrosr 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 monaner is volatile, it is released frem 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 O. S. H. A. Standard for details. Analysis has shown that areas where vinyl monomer might concentrate are: (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 noncmer or adequate protection provided prior to exposure of personnel. (2) In processing areas such as ccrpound preparation, spraying, or coating. Suitable ventilation should be provided. (3) In drying and curing areas. Normal good operating practice in exhausting volatiles may be sufficient. Ihe concentration of vinyl chloride monomer at the mandated exposure limits cannot be detected by odor 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. AP00034584 8100 OAK T ft E E SOUUVAAO B.P. Goodrich Chemical Company 1 OIVIIIQN Of TKt I f. OOOOHICH CflUPIHf C L E V E l AN 0 . 0 N I 0 44131 ftHONE: 218-52 4 - 0 2 0 0 January 6, 1975 RLS-3-75 Gentlemen: Over the past year, our company has attempted to provide our customers with information pertinent to the vinyl chloride monomer issue. Hy June 7, 1974 letter focused on the level of residual vinyl chloride monomer (RVCM) present in cur PVC latex products and described handling and processing conditions where monomer accumulation could occur. A copy of tills letter is enclosed for ready reference. As noted in the reference letter, efforts toward reducing RVCM levels were underway. As a result of this exploratory effort and subsequent process development and design work, we can now project realistic time and monomer level targets for our PVC latex products. This information will doubtless be useful to processors that are now, or will soon begin, formulating planB for in-plant air quality evaluation and improvement actions. A high efficiency process for residual monomer reduction has been selected and is expected to be operational by the third quarter. This timing estimate is based on a current schedule for delivery and installation of new process and control equipment. With design performance, an approximate 100 fold reduction in present RVCM levels will be attained. A 10 fold reduction will be achieved effective January 1, 1975, through process modifications utilizing available equipment. Manufacturing specifications will be changed accordingly and these changes are summarized below. CD PVC LATEX (2) % RVCM - Solids Weight Basis Approximate 1974 Average Target Manufacturing Specifications January 1, 1975 September 1975 0.1# 0.01% (maximum) 0.001% (maximum) (1) Geon Latex products, excluding non-PVG Geon 660 series - includes Hycar 2600X189, a PVC modified acrylic latex. (2) Corresponds to billing weight: % Total Solids % RVCM (wet wt. basis) = % RVCM (solids wt. basis) x 100 AP00034585 2- While the January 1, 1975 specification of Q.Q1% (max.) will apply to all new latex production and subsequent bulk shipments, present warehouse drum inventories will be cleared before drum quantities of the lower RVCM product can be readily supplied. During this period of inventory clearing, we will attempt to supply trial quantities of the 0.01% specification product to drum customers that might want to measure the resulting impact on plant air quality. Such special requests can best be handled through direct communication with your area salesman. The supply projections given here necessarily involve timing estimates that are dependent on equipment deliveries. You will be advised of any complications or delays which could affect these projections. Sincerely, R. L. Steller, Product Director Latex and Specialty Chemicals /p AP00034586
