In keeping with its position as a lead ing producer of vinyl chloride monomer for the merchant market only. PPG In dustries expanded its Lake Charles, Louisiana, vinyl chloride plant in 1969. The Guayanilla, Puerto Rico plant, built in 1971, greatly increased PPG's capacity for making vinyl chloride monomer. A new large tanker, the S.S. Puerto Rican, transports refrigerated vinyl chloride monomer to a newly built ter minal at Paulsboro, New Jersey, where it is stored under refrigeration. PPG produces vinyl chloride monomer by the oxychlorination of ethylene and holds more than 400 domestic and for eign patents on this process. Uninhibited VCM is quite stable and can be routinely shipped, handled and stored provided proper procedures, out lined below, are followed. To prevent polymerization in transit or storage, it is essential that the monomer be protected at all times from contact with air, oxy gen, moisture, catalytic impurities, and light. PPG normally supplies VCM unin hibited. The use of uninhibited VCM eliminates the need for subsequent pro cessing to remove the inhibitor. If re quired, suitable inhibitors will be added. GRADES PPG Industries produces polymergrade vinyl chloride monomer. USES Most vinyl chloride is polymerized to polyvinyl chloride (PVC) or copoly merized with other monomers such as PPG's vinyhdene chloride. thylene;| At the PPG plant in Guayanilla, Puerto Rico, the company's modern 34,000-ton chemical tanker, S.S.

If an inhibitor is included, it may cause local skin burns. Vapor concentrations in work areas should not exceed 200 ppm as a timeweighted average atmospheric concen tration for an 8-hour dav to avoid adverse effects on workmen. High vapor concentrations can cause dizziness and anes thesia. More information appears in Chemical Safety Data Sheet SD-56.

Wash ington, D C 20009 HANDLING AND STORAGE Aluminum and its alloys must not be used in equipment to store or handle vinyl chloride because explosive alumi num chloroalkyls can be formed PPG's \ inv l chloride is made 1 rom ethy lene and contains no detectable amount of acety lene Vm\l chloride made from acetylene by an older process contains traces of acetylene that could react explosively with copper or its alloys to form copper acetylides It :s not sale to use such vinyl chloride in processing equipment con taining copper or brass. Exposure of vinyl chloride to oxygen and air results, after a time, in polymer lormatton This can cause problems in equipment used for storage and transler of monomer. Vinyl chloride should be stored under a blanket of nitrogen with a maximum oxygen content of 10 ppm Fire hazard Vinyl chloride vapor is extremely flam mable Its explosive limits are between 3.6 and 33G by volume - air. Proper ventilation and the elirr .n of igni tion sources are mane in areas u here vapor concentratn -v reach a flammable level. When a .r is un loaded, both the car tank .he un loading pump should be electrically grounded. The major products of combustion in clude toxic and corrosive hydrogen chloride as well as carbon monoxide, and less than 10 ppm of phosgene Only in the very near vicinity of a vinyl chlo ride monomer fire could detectable amounts of phosgene be present Carbon dioxide or dry chemical j- gents extinguish small fires effectively, but no extinguisher is known for large tires Streams of water cannot extin guish a liquid vinyl chloride fire because the monomer does not mix with water and vv ill float on top. Water may be spraved to eooi equipment If the source of the vinyl chloride monomer leak has not been closed off. do not attempt to extinguish a large fire because hot metal can re-ignite an unburned vapor cloud \o one without proper protective respiratory equipment should enter an area where there has been a lire until ^he area has been adequately ventilated Unloading tank cars it rank ear valves are defective or leakv. do not unload.

PACKAGING AND SHIPPING PPG Industries delivers vinyl cb' ' by ship, barge, tank car and tan- There are 3 shipping point .-.c Charles, Louisiana: Guayaniliu, . .erto Rico: and Paulsboro, New Jersey. PPG maintains a fleet of tank cars for vinyl chloride service Nil cars are equipped for top unloading. There are three car sizes. 100.000-pound, 180,000- pound and 220,000-pound net weight Tank trucks hold up to 40,000 pounds Ships and barges hold up to se'er = million pounds. SAMPLES AND SERVICE Samples of \ inyl chloride are on special request in returnable tory-size steel cylinders holding 5 pounds or in cylinders holding 200 pounds. The technical service staff of PPG In dustries Chemical Division is available for consulting on handling, storage and Storage spheres at PPG s Lake Charles Louisiana plant hold thousands of gallons eacn of liquid vinyl ch'cride monomer under pressure Horizontal storage tanks at right serve as cav tanks.
