Description

Acrylonitrile, stabilized appears as a clear colorless liquid with a strong pungent odor. Flash point 32°F. Prolonged exposure to the vapors or skin contact harmful. Density 6.7 lb / gal. Vapors heavier than air. Combustion produces toxic oxides of nitrogen. Requires storage and handling in closed systems. Used in insecticides and to make plastics, fibers and other chemicals. Rate of onset: Immediate Persistence: Minutes to hours Odor threshold: 17 ppm Source/use/other hazard: Plastics, coatings, adhesives industries; dyes; pharmaceuticals; flam gas.;Liquid;COLOURLESS OR PALE YELLOW LIQUID WITH PUNGENT ODOUR.;Colorless to pale-yellow liquid with an unpleasant odor.;Colorless to pale-yellow liquid with an unpleasant odor. [Note: Odor can only be detected above the PEL.]
