Liquid vinylidene chloride is irritating to the eyes and skin. The inhibitor can cause local skin irritation or burns unless washed off thoroughly. Since the odor threshold lies between 500 and 1000 ppm, the odor of vinylidene chloride is not an adequate warning to prevent overexposure. Chronic - In recent preliminary animal studies, it has been reported that vinylidene chloride in concentrations higher than the present ACGIH threshold limit value (TLV) of 10 ppm may be carcinogenic to some species of experimental laboratory animals via inhalation. Although these findings are preliminary and incomplete, it is suggested that air concentrations of vinylidene chloride in the work area be maintained below 10 ppm at all times. It is also recormended that the 8-hour time weighted average (TWA) be maintained as far below 10 ppm as practical. Chronic exposure to low concentrations of vinylidene chloride can result in injury to the liver and kidneys. Emergency and First Aid Procedures: Inhalation Overexposure - Remove to fresh air. If not breathing, give artificial respiration, preferable mouth-to-mouth. If breathing is difficult, give oxygen. Call a physician. Eye or skin contact - Imnediately flush with plenty of water (soap and water for skin)for at least 15 minutes. If irritation occurs, consult a physician. Wash contaminated clothing before reuse. Section VIII - Special Protection Information Respiratory protection: Wear NIOSH/MESA - approved non-air purifying respiratory protection where concentrations cannot be maintained below 10 ppm. Establish a respiratory protection program in accordance with the minimum requirements of 29 CFR 1910.134 (May 28, 1975). 073589 Sb Vinylidene chloride monomer (VDC) is a versatile product used with other monomers to make a wide variety of copolymer resins and latices. Properly inhibited and protected from exposure to air, oxygen, water and light, VDC is stable in shipment and storage at ambient temperatures. Correct han dling practices, outlined below must be followed at all times. VDC supplied by PPG Industries' Chemicals Group from its Lake Charles, Louisiana, plant is inhibited with hydroquinone monomethyl ether (HQMME or MEHQ) to prevent polymerization during shipment and storage. It is shipped under a nitrogen blanket to avoid contact with air and to prevent the formation of a peroxide that can act as a polymerization initiator. For most applications, the MEHQ in hibitor in PPG vinylidene chloride need not be removed. If uninhibited monomer is required, however, the MEHQ can be removed by distillation or alkali extraction, GRADES The standard grade of VDC manufac tured by PPG is inhibited with hydroquinone monomethyl ether at ap proximately 200 parts per million. resistance, and impermeability to water vapor and gases. Data on reactivity ratios of VDC copolymerizations with 36 monomers are presented in a booklet, "Vinylidene Chloride Handling, Properties and Reactivity Ratios," Form A-967-120R, available on request from PPG Indus tries' Chemicals Group.

The copolymer resins and latices are formed into films, fibers, coatings and linings. VDC imparts to finished products qualities of flame retardance, chemical Solubility.Reactivity: Vinylidene chloride is practically insoluble in water (0.04 weight % at 20C) but soluble in most organic solvents. Uninhibited, or inhibitor-depleted, vinylidene chloride may polymerize very slowly even in the absence of oxygen. To further retard polymerization, the uninhibited monomer should be maintained in darkness below 14F (- 10C). Uninhibited, or inhibitor-depleted, vinylidene chloride re acts readily with oxygen or air to form a peroxide at temper atures as low as -40For C. 073590 SD Specification and typical analysis; Appearance Color, APHA Vinylidene Chloride, weight % (excluding inhibitor) Acetylene, as C2H2, ppm Specification clear, free of suspended matter 25 maximum 99.6 maximum Typical Analysis clear, free of suspended matter 5 99.9 25 maximum <1 Other Chlorinated Hydrocarbons, no 10 one to exceed this weight % Acidity, as HC1, ppm Peroxide, as H202, ppm 0.25 maximum 10 maximum 10 maximum 0.1 <1 <1 Water, ppm Inhibitor, HQMME*, ppm 50 maximum 180 to 220 30 200 *Hydroquinone monomethyl ether is sometimes referred to as MEHQ (monomethyl ether of hydroquinone). enness, and -- if continued -- to uncon HANDLING AND STORAGE sciousness and, ultimately, death.

The potent tial presence of peroxide can frequently be detected by sharp, acrid odors or by the precipitation of a white flocculent polymer. Dried polymer residues may contain adsorbed peroxide which can be exploded by a slight mechanical shock or by heat. These residues should be handled with extreme caution. Adding water that is at room temperature to polymer residues containing peroxide renders them inactive. However, the hazard may return if the water evapo rates. The peroxide can be destroyed by several washes with a 5 % by volume so lution of methanol in perchlorethylene. Any peroxide present as a precipitate in monomer can be destroyed by mixing with one part perchlorethylenemethanol solution and four parts vi nylidene chloride monomer. Separation and handling of precipitated polymer, and its potentially dangerous adsorbed peroxide, must be done with extreme caution.
