Its vapor and air can form explosive mixtures. In case of fire, explosion fever burns easily. Contact with oxidants strong reaction, and even cause a fire. In case of high fever, can occur polymerization reaction and emit heat and large containers ruptured and caused the explosion. Because of flow, agitation, etc., may generate static electricity. Its vapor is heavier than air, it will spread to the lower Department of considerable local and met the fire will generate a return to burning.
