In addition to the risk of fire or explosion, it is irritating to the skin and eyes and may cause burns. Work areas where vinyliderifc ehlbYTde is handled or stored should be well ventilated in order to keep the concentration below the saf lower explosive limit at all times. Over-exposure can lead to anesthesia. It is recommended that concentrations of vinylidene chloride in air b * monitored and maintained at levels below 100 ppm. Vin.y'lidftne^ghloride vapors burn strongly but not violently. Recom- , mended fire extinguishers are foam, carbon dioxide, and dry chemicals, using a water spray for cooling as required. Employees working in areas where vinylidene. chloride is handled or stored should be thoroughly familiar with the hazards associated with its use. Emphasis in training should be placed on the use of personal pro tective equipment, fire-fighting equipment, location of safety equipment, and first-aid measures. SHIPPING Vinylidene chloride, inhibited as required, is shipped in the follow ing containers: Container Tank Cars ICC Specification Pounds, Net (approximate) 105,000 105,000 Tank Trailers 25,000 55-gal drums (non-returnable) 500 5-gal drums (non-returnable) 45 SL 045489 -3- All shipments are made in accordance with ICC regulations. The vapor space in all containers is filled witn nitrogen. Each container bears the ICC red label for FLAMMABLE liquids, and the following warning;lab 1: DANGER*. . EXTREMELY FLAMMABLE LIQUID. . MAY CAUSE BURNS. Keep container closed and away from heat, sparks, and open flame. Use with adequate ventilation. Avoid prolonged breathing of vapor. Avoid contact with skin, eyes, and clothing. In case of contact, immediately remove all contaminated clothing and flush skin and eyes with plenty of water; for eyes,- get'medical attention. UNLOADING TANK CARS ' Applicable instructions for unloading tank cars containing flammabl liquids are set forth in Manufacturing Chemists* Association Manual Sheet TC-4. Also see ICC Regulations, Sec. 74.560 to 74.563 inclusive, for un loading tank cars. Under no circumstances should air be permitted to enter vinyliden chloride tank cars, for this, can lead to the formation of hazardous peroxides^ Accordingly, 5-10 pounds positive nitrogen pressure should always-be left in empty cars. If tank cars are found to be leaking, or to have defective valves. immediately notify Ethyl Corporation, 100 Park Avenue, New York, N. Y., 10017 (Phone area code 212, ORegon 9-2000). STORAGE Vinylidene chloride must be stored away from light or air. It is recommended that positive nitrogen pressure be maintained in the vapor spac Storage areas should.be selected in accordance with local codes or authorities having jurisdiction. Assistance is available from such organizations as National Board of Fire Underwriters and Factory Insurance Association. Tanks, valves, pipes and fittings coming into, contact with vinvlidepe chloride liquid or vapor should be constructed' o3rpte5U5rnIckel." 1C oppe r l and cuppel1 containing alloys, such as brass and monel, should not be use r\b cause of the possible presence of acetylenic compounds. f--------__________ SL 045490 4 Storage tanks should be constructed according to ASME Code, Section VIII, for at least 30 psi maximum design working pressure and full vacuum. Frangible safety discs are recommended instead of relief valves, for corrosion and polymer may render relief valves ineffective. * All liquid inlet lines should enter or extend to the bottom of the vessel. This guards against the accumulation of static electricity. All equipment should be properly grounded. Adequate-diking should be provided under the tank area to confine liquid in case of tank rupture. HAZARDOUS PEROXIDES When vinylidene chloride is stored in the presence of air or oxygen, a peroxide compound of undetermined structure is' formed. Even when an in hibitor is present, oxygen exposure should be avoided, for the inhibitor may be used up and the peroxide compound can still form. Formation of these peroxides is often accompanied by the precipitation of a flocculent vinylidene ctuorloe polymer^ Thg^po-roxide"catb4>e-explosive, and since it is absorbed on the pre- st be regarded as explosive when separated If dry and. containing more than about 15% * , _________ _______etonate from a slight mechanical shock or from heat. Polyvinylidene chloride, free of peroxides, is not explosive. Probable exposure to oxygen, and consequently the possible presence of peroxides, is indicated in two ways: (1) Peroxides decompose to form phosgene, hydrochloric acid and formaldehyde, all of which give off a sharp odor even at low concentrations; (2) the appearance of polymer is anoth r indication of possible oxygen exposure. Confirmation of the presence of peroxide can be determined by the liberation of iodine from a slightly acidified dilute potassium iodide solution. Upon evaporation of vinylidene chloride, residues may remain. These residues, as sometimes found in pipes, lines, laboratory equipment and storage vessels, should be handled with caution for they may contain peroxides. The residues can be rendered inactive by immediately flushing them with wat r. It is recommended that large scale equipment, used on an intermittent basls^ be filled with water when not in use. SPILLS AND LEAKS Spills and leaks should be attended to immediately. Ignition sources should be eliminated from the area. It is recommended that spilled vinylid ne chloride be covered with an absorbing medium, such as sand. After the ab sorbent has soaked up the vinylidene chloride, it can be removed to a safe area. SL 045491 5- The volatility of vinylidone chloride la great enough to allow con centrations exceeding 2% to be present in the air in the immediate area of a spill. Consequently* gas masks or air masks should be worn* SERVICE Ethyl Corporation maintains a technical staff as a service to assure vinylidene chloride customers of a reliable supply of high quality product. Requests for samples* further information* or the assistance f a technical representative are welcomed. Ethyl Corporation Industrial Chemicals Division 100 Park.Avenue ' Ne#< w Yo,r. k, N.
