It is used to make plastics and adhesives, and to make other chemicals. It is shipped as a liquefied gas under its vapor pressure Contact with the liquid can cause frostbite. It is easily ignited. Its vapors are heavier than air and a flame can flash back to the source of leak very easily. This leak may be either a liquid or vapor leak. It can asphyxiate by the displacement of air. Under fire conditions the cylinders or tank cars may violent!* rupture and rocket. Prolonged exposure of the cylinders or tank cars to heat or fire may cause the materiaI to polymerize with possible container rupture. This material is a cancer suspect agent on long term exposure to low concentrations. However, this effect has not been demonstrated for single exposures to high concentrations of the material. If material on fire or involved In fire Do not extinguish fire unless flow can be stopped Use water in flooding quantities as fog Cool all affected containers with flooding quantities of water Apply water from as far a distance as possible If material not on fire and not involved in fire Keep sparks, flames, and other sources of ignition away Keep matenal out of water sources and sewers Attempt to stop leak it without hazard Use water spray to knock-down vapors Personnel protection. Avoid breathing vapors Keep upwind Wear self-contained breathing apparatus Wear protective gloves and goggles Do not handle broken packages without protective equipment Approach fire with caution Evacuation If fire becomes uncontrollable or container is exposed to direct flame--evacuate for a radius of 2500 feet If matenal leaking (not on fire), downwind evacuation must be considered VINYL ETHYL ETHER, INHIBITED 4907275 FLAMMABLE LIQUID UN 1302 POLYMERIZABLE Vinyl ethyl ether, inhibited is a clear colorless liquid with an ether-iike odor. It has a flash point of less than -50 deg. F. If the material is subject to heat for prolonged periods or becomes contaminated, it is subject to polymerization with evolution of heat. If the polymerization takes place inside a container, the container may violently rupture, The material is lighter than water and slightly soluble in water its vapors are heavier than air. If material on firs or Involved In fire Do not extinguish fire unless flow can be stopped Use water in flooding quantities as fog Solid streams of water may spread fire Cool all affected containers with flooding quantities of water Apply water from as far a distance as possible Use "alcohol" foam, carbon dioxide or dry chemical If material not on firs and not Involved in fire Keep sparks, flames, and other sources of ignition away Keep material out of water sources and sewers Build dikes to contain flow as necessary Attempt to stop leak if without hazard Use water spray to knock-down vapors Personnel protection Avoid breathing vapors Keep upwind Wear self-contained breathing apparatus Wear boots, protective gloves, and goggles Do not handle broken packages without protective equipment Wash away any material which may have contacted the body wit; copious amounts of water or soap and water Continued on next peg 52 GGC 002330
