Explosion data is information on the explosive properties of a material. Quantitative explosion data is seldom available and is usually given in descriptive terms such as low, moderate or high. The following types of information can be used to describe the explosive hazard of a material: 1. Sensitivity to mechanical impact. This information indicates whether or not the material will burn or explode on shock (for example, dropping a package) or friction (for example, scooping up spilled material). 2. Sensitivity to static discharge. This information indicates how readily the material can be ignited by an electric spark. | Detailed information is available on the properties of commercial explosives. In Canada, the storage, transportation and handling of commercial explosives are strictly regulated under the Explosives Act and Transport of Dangerous Goods Act. Commercial explosives are not regulated by the Controlled Products Regulations [e.g.,: not part of the Workplace Hazardous Materials Information System (WHMIS)]. | Under the U.S. OSHA HAZCOM standard, a chemical is identified as explosive if it causes a sudden, almost instantaneous release of pressure, gas and heat when subjected to sudden shock, pressure or high temperature.
