The chemical is a flammable solids (burning generally below 300 ℃, low melting point are flash point below 100 ℃, easy to burn an explosion, burning speed, toxic combustion products), the event of fire, high temperature can cause decomposition of explosions and combustion; with alkali, acid or acid fog exposure will quickly burst into flames; and oxidant mixture can form explosive mixtures; by friction, vibration or impact may cause a fire or explosion; thermal decomposition can produce toxic fumes of nitrogen oxides.
