Wikipedia
A pyrotechnician is a person who is responsible for the safe storage, handling, and functioning of pyrotechnics and pyrotechnic devices. Although the term is generally used in reference to individuals who operate pyrotechnics in the entertainment industry, it can include all individuals who regularly handle explosives. For the purposes of disambiguation, however, individuals who handle more powerful materials for commercial, demolition, or military applications are generally referred to as explosive technicians.
