Pyrotechnics

by George Weingart

Pyrotechnic devices combine high reliability with very compact and efficient energy storage, in the form chemical energy which is converted to expanding hot gases either through deflagration or detonation. The controlled action of a pyrotechnic device (initiated by any of several means, including an electrical signal, optical signal or mechanical impetus) makes possible a wide range of automated and/or remote mechanical actions; for example, the deployment of safety equipment and services, precisely timed release sequences, etc. The majority of the technical pyrotechnic devices use propellants in their function, a minority use materials that are classified as primary or secondary explosives to obtain very fast and powerful mechanical (mostly cutting) actions; for example cable cutters, exploding bolts, or similar pyrotechnic fasteners. Individuals responsible for the safe storage, handling, and functioning of pyrotechnic devices are referred to as pyrotechnicians. Explosions, flashes, smoke, flames, fireworks or other propellant driven effects used in the entertainment industry are referred to as pyrotechnic special effects, theatrical effects, or proximate pyrotechnics. Proximate refers to the pyrotechnic device's location relative to an audience. In the majority of jurisdictions, special training and licensing must be obtained from local authorities to legally prepare and use proximate pyrotechnics.

2 reasons to read this: to learn how to safely make and use display fireworks, and to see just how many freedoms we've lost in the last few decades.
