Principles, Safety, and a Database of Fireworks

Abstract

Principles and safety of fireworks as well as the database that the authors have been opened to the public are overviewed. First, chemical substances used to make fireworks are explained. Especially, oxidizers, which are solid powders including oxygen, are focused on. The reasons why the oxidants that are currently used have been selected to make fireworks are scientifically explained. Moreover, issues related to combustible substances are explained in detail. Next, the safety of fireworks is outlined. AIST has been addressing this issue for a long time. Various types of laboratory-scale sensitivity tests, evaluation tests for the hazard of spontaneous ignition, and safe production methods are explained. Finally, in “Physical Hazard Database of Chemicals,” a database developed by the authors and opened to the public, the parts related to fireworks are introduced.
