Legal issues

The legal status of firecrackers typically stems from their notable effect on noise pollution as well as the issue of their safety, especially when used by children. Devices which are designed to explode at ground level are seen as more dangerous than those with a prolonged burn time and/or an aerial explosion. Proponents of firecracker sales sometimes question the consistency of these laws, pointing out that legal fireworks can also be dangerous due to the risk of high-temperature burns (as in the case of sparklers), and that projectile fireworks intended for aerial use can often legally incorporate a noisemaking explosive device as a last stage. Noise pollution is unwanted human-created sound that disrupts the environment. ... Warning signs, such as this one, can improve safety awareness. ...

Note that firecrackers are virtually all scientifically classed as "low explosives" which burn through deflagration, as opposed to "high explosives" such as dynamite which actually produce a supersonic detonation wave. Some legal definitions nevertheless define banned firecrackers (such as the M-80 in the United States) as "high explosives". Deflagration is a process of subsonic combustion that usually propagates through thermoconductivity (hot burning material heats next layer of cold material and ignites it). ... Dynamite is an explosive based on the explosive potential of nitroglycerin using diatomaceous earth (Kieselguhr) as an absorbent. ...

Novelty noisemakers

In general, novelty noisemakers, such as "party poppers" or "snappers" (usually called "trick noisemakers") are not considered true fireworks, and are legal in many places where fireworks are not.
