A chemical explosive is a compound or mixture which, upon the application of heat or shock, decomposes or rearranges with extreme rapidity, yielding much gas and heat. explosive compound was successfully identified [39]. explosive materials as follows: a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such temperature and pressure and at such speed as to cause damage to the surroundings. Chemistry of Explosives Explosives are chemical mixtures or compounds that, when subjected to heat, impact, or shock, are capable of undergoing a rapid decomposition that releases heat and gases, which, in turn, expand to form high pressures. Introduction Many are downloadable. Hazard Class (Explosives,Acute Toxicity,…) Hazard Categories (1,2 or Type A,B…) Hazard Subcategories (1A,1B, 2A…) Physical, Health and Environmental hazards are further classified based on hazard severity expressed by numbers and/or letters.
