    • H314-H330-H335

    • In case of H, the pore-forming agent is flammable; in case of cyanide, it emits highly toxic hydrogen cyanide gas; in the case of flammable organic matter burning or exploding; heat produces toxic sulfur oxide fumes

    • Risk of fire and explosion on contact with base(s), combustible substances, reducing agents or water.

    • Explosive when exposed to water

    • Inhalation-Rat LC50: 347 PPM/1 hour

    • highly toxic

    Product Usage

    In manufacture of fertilizers, explosives, dyestuffs, other acids, parchment paper, glue, purification of petroleum, pickling of metal.
