Pyrotechnics
Pyrotechnics is the controlled use of combustible or explosive compositions to produce effects such as light, heat, sound, flame, or smoke.
Combustion: Combustion is a chemical reaction in which a fuel reacts rapidly with an oxidizer, releasing heat and often light. Pyrotechnic compositions produce effects through controlled combustion.
Fireworks: Fireworks are devices that use pyrotechnic compositions to create visual or auditory effects in the atmosphere. They are the most visible public use of pyrotechnics.
Detonation: Detonation is a reaction that propagates through an explosive material as a shock wave traveling faster than sound. It differs from the subsonic burning used in many pyrotechnic effects.
Fuel: A fuel is a substance that releases energy through a chemical reaction, commonly by oxidation. Fuel supplies the chemical energy released in a pyrotechnic composition.
Fire safety: Fire safety comprises practices and systems that prevent fires and reduce harm when they occur. Burning compositions, hot debris, and ignition sources make fire prevention central to pyrotechnic use.
Oxidizer: An oxidizer is a substance that enables oxidation by accepting electrons or supplying oxygen or another oxidizing agent. Many pyrotechnic mixtures carry their own oxidizer, allowing combustion without relying on air.
Flare: A flare is a device that produces intense light or heat for illumination, signaling, or countermeasures. Pyrotechnic flares turn controlled burning into visible signals or defensive decoys.
High explosive: A high explosive is a material that can detonate, producing a rapidly expanding shock wave. Pyrotechnic compositions are generally designed for effects rather than high-explosive shock.
Ignition: Ignition is the initiation of a combustion reaction by supplying sufficient energy. A pyrotechnic composition needs an ignition source to begin its intended reaction.
Noise pollution: Noise pollution is unwanted or harmful sound that disrupts people, animals, or environments. Loud pyrotechnic reports can disturb communities and wildlife.
