It is very flammable and can catch on fire by static L.y X'/ti-sn o. wctiut* The following practices are recommended when tanker ships are carrying vinyl chloric LOADING: 3efore loading vinyl chloride, the tanks must be free of oxygen to prevent an explosive mixture being present or a reaction of the oxygen with the vinyl chloride. The ship should have it's own method of analyzing empty tanks fer oxyger*. The tanks must also be clear of the previous cargo to prevent ccr.tanina of the vinyl chloride and the possibility of a reaction between the last cargo `and the vinyl chloride. MIXING WITH OTHER CARGOES: In loading and transferring vinyl chloride, all piping must be clean of previous cargoes, otherwise a reaction might start in the pipe. REACTIONS: Vinyl chloride will react with the oxygen in the air. Care should be taker, than no air enters che tanks through leaky packing on compressors or a leaking suctio flange on the compressor. Phenol or hydrocuinone is added to the vinyl chloride at the time of loading. It's purpose is to prevent small amounts of air from reacting with the cargo. As long as no air enters the tanks, this inhibitor will be available. However, if more air enters the tanks than car. be handled by the inhibitor, you will see a slow build-up in the temperature and pressure of the cargo. If this happens, a reaction is taking place within the tank. In this case, the cargo shculc be vented to maintain a safe pressure and a low temperature. When venting the carg the vapors are much heavier than air and will settle from the vent stack and can burn if they come in contact with dry heat of approximately S00? or open flame. The attached graphs can be used to determine if changes in pressure are due to changes' in temperature or not. The temperature and/or pressure of the tanks should be recorded so that you can be aware of any change in the condition of the cargo. TEN 2888 I 2- - LEAKS: Small leaks car. usually be found by the odor of escaping vinyl chloride. They ir.ay also be found with an explosion tie ter. The fumes are twice as heavy as air and will collect in the bilge or any low part of the ship and form an explosive condition. The insulation on the tanks will usually allow leaking vinyl chloride to flow down the outside of the tank and into the bilge. This is a very dangerous condition. RUPTURE o \ VT/ C . If the tanks containing vinyl chloride should rupture or develop a large leak, the vinyl chloride will escape. As it escapes, it will build static electric! which may ignite the vir.yl chloride. Every effort must be made to stop leaks the tank or piping without welding. If the leak cannot be stopped, the cargo will be cooled as it boils off. This will make the vinyl chloride escape slew and will extend the possibility of fire or explosion. BURNING: Burning vinyl chloride gives off carbon monoxide which is a deadly poison and `hydrogen chloride which is an acid and will burn the lungs. , The crew should stay upwind of the fire. The hydrogen chloride will destroy any wet metal. A large stream of water should be used on the gases coming off of the fire. The fire should not be put out due to the possibility of flashback.
