'''Pirotehnika''' je nauka о korišćenju meterijala koji imaju sposobnost of undergoing self-contained and self-sustained [[exothermic]] chemical reactions for the production of heat, light, gas, smoke and/or sound. Its [[etymology]] stems from the Greek words ''pyro'' ("fire") and ''tekhnikos'' ("made by art").<ref>[http://dictionary.reference.com/browse/pyrotechnics Pyrotechnics | Define Pyrotechnics at Dictionary.com]</ref> Pyrotechnics include not only the manufacture of [[fireworks]] but items such as [[safety matches]], oxygen candles, [[Pyrotechnic fastener|explosive bolts and fasteners]], components of the automotive [[airbag]] and gas pressure blasting in mining, quarrying and demolition.
Individuals responsible for the safe storage, handling, and functioning of pyrotechnic devices are referred to as [[pyrotechnician]]s.
== Proksimalna pirotehnika ==
Explosions, flashes, smoke, flames, fireworks or other pyrotechnic driven effects used in the entertainment industry are referred to as theatrical special effects, special effects, ili proksimalna pirotehnika. 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.

Many musical groups use pyrotechnics to enhance their live shows. [[Pink Floyd]] were innovators of pyrotechnic use in concerts. For instance, at the climax of their song "[[Careful with That Axe, Eugene]]", a blast of smoke was set off at the back of the stage. Bands such as [[The Who]], [[Kiss (band)|KISS]] and [[Queen (band)#Live performances|Queen]] soon followed with use of pyrotechnics in their shows. [[Michael Jackson]] attempted using pyrotechnics in a 1984 Pepsi advertisement,<ref>[http://news.bbc.co.uk/onthisday/hi/dates/stories/january/27/newsid_4046000/4046605.stm BBC ON THIS DAY | 27 | 1984: Michael Jackson burned in Pepsi ad<!-- Bot generated title -->]</ref> where a stray spark caused a small fire in his hair. German industrial metal band [[Rammstein]] are renowned for their incorporation of a large variety of pyrotechnics into performances, which range from flaming costumes to face-mounted flamethrowers. [[Nightwish]], [[Lordi]] and [[Green Day]] are also known for their vivid pyrotechnics in concert. Many professional wrestlers have also used pyrotechnics as part of their entrances to the ring. ▲

Prikazna pirotehnika, also known as commercial fireworks, are pyrotechnic devices intended for use outdoors, where the audience can be further away, and smoke and fallout is less of a concern. Generally the effects, though often similar to proximate pyrotechnics, are of a larger size and more vigorous in nature. It will typically take an entire day to set up a professional fireworks display. The size of these fireworks can range from 50 mm (2") to over 600 mm (24") diameter depending on the type of effect and available distance from the audience. In most jurisdictions, special fireworks training and licensing must be obtained from local authorities to legally prepare and use display pyrotechnics.
== Potrošačka pirotehnika ==
Consumer pyrotechnics are devices readily available for purchase to the [[general public]] with little or no special licensing or training. These items are considered ''relatively'' low hazard devices but, like all pyrotechnics, can still be hazardous and should be stored, handled and used appropriately. Some of the most common examples of consumer pyrotechnics encountered include recreational [[fireworks]] (including whistling and sparking types), [[model rocket#Motors|model rocket motors]], highway and marine distress [[flares]], [[sparklers]] and caps for toy guns. Pyrotechnics are also indirectly involved in other consumer products such as powder actuated [[nail gun]]s, [[ammunition]] for [[firearms]], and modern [[fireplaces]]. Some types, including [[bird scarer]]s, shell crackers, whistle crackers and flares, may be designed to be fired from a [[12-gauge]] pistol or rifle.
== Bezbednost ==
Pyrotechnics are dangerous and must be handled and used properly. Recently, several high-profile incidents involving pyrotechnics have re-enforced the need to respect these explosives at all times. Proximate pyrotechnics is an area of expertise that requires additional training beyond that of other professional pyrotechnics areas and the use of devices specifically manufactured for indoor, close proximity use.

[[Image:Hazardous Homemade Pyrotechnic Flash Pot.jpg|thumb|250px|Homemade flashpots built without any safety mechanisms]]
A common low-budget pyrotechnic flash pot is built using modified screw-in electric fuses in a common light fixture. The fuses are intentionally blown, acting as ignitors for a pyrotechnic material.
Homemade devices may fail to include safety features and can provide numerous hazards, including:
* A firing circuit using high-power, non-isolated AC line voltage can be a shock hazard to the operator and bystanders.
* The use of high-current fuses as ignitors can cause main circuit breakers and fuses to trip, due to the sudden inrush of hundreds of amperes through a dead-shorted circuit. Switches used to control ignition may be damaged from the high-current surges.
* There may not be indicators or interlocks preventing premature ignition of the pyrotechnic material. Screwing a powder-loaded fuse into an unknowingly powered socket will result in immediate ignition, injuring the operator.
Commercial flash pots include safety features such as warning pilot lamps, preignition grounding, and safing circuits. They also use isolated and low-voltage power sources, and have keyed power connections to help prevent accidental ignition.
