Physical Hazard Database of chemicals

This data base is being compiled under the commission of METI as a basis for the development of technical standards for firework production. Sensitivity/strength test data obtained for powders used in fireworks are compiled in order to estimate their explosion hazard.

The following performance tests for explosives were performed on representative base compositions produced in Japanese firework factories.
