Decomposes above 212 \u00b0F. A suspected carcinogen. Extremely hazardous as a mutagen. Avoid skin contact and inhalation of of vapors. Usually stored frozen (below 32 \u00b0F) in polyethylene bottles that are tightly closed and contained in a metal can. May decomposed during prolonged storage and develop sufficient pressure in a closed container to explode. Keep away from heat, sparks, and open flame."}]
