SAMpowder Posted June 16 Posted June 16 Regarding the types of fireworks, is the following classification accurate? Based on the ignition effect, there are primarily thirteen major categories: spray flower class, rotating class, rotating and ascending class, rocket class, pearl class, small flower class, smoke class, shape toy class, combination fireworks class, incense stick class, friction bomb class and fireworks shells. Specifically they can be further divided into cold light fireworks, fireworks shells, flowerpots, Roman candles, rockets, electric sparklers, stage pyrotechnics, cold flames, instantaneous pyrotechnics, torch pyrotechnics toy pyrotechnics firecrackers stage fountains pyramid fireworks daytime scenery fireworks etc., totaling more than 3000 types. The main types include "fireworks subtitles", "fireworks shells", "flowerpots", "rockets", "large colorful wheels" and "pyramid fireworks". Every year there are dozens to hundreds of different categories and specifications available.
Zumber Posted June 16 Posted June 16 In our country it is classified as a Consumer fireworks and display fireworks where prepared items are permitted to sale to customer and customer ignites it. Display fireworks is a type where prepared items is not sold to customer instead licence holder display person actually arrange display at customers place and safely ignites display items. Consumer and display fireworks are again categorised as a Class 1, 2,3 and so on.....

Cold fireworks/fountain also exists....it uses cotton nitrate plus very few percent of AP and titanium as a spark producing agent pressed in a nozzle less tube it is also termed as a smokeless fountain.

a_bab Posted June 18 Posted June 18 Whoever invented the term "cold fireworks" should have been shot in the knee on the spot. This term is totally misleading; there is nothing cold about the indoor gerbs based on NC with some Ti fines added. Because of the false security this term inspires, there have been a number of tragic accidents because the so-called cold sparks are able to set things on fire just like any spark. And this happened in clubs or other crowded places. These accidents have probably killed over 100 people in total so far. I know of about at least 60 documented deaths. So cold fireworks my ass.
Zumber Posted June 19 Posted June 19 If there is fire there is heat. The term cold doesnt mean that there is no any heat at all....the similar term is smokeless which actually doesnt mean there is no smoke at all it means it produces a little smoke....
a_bab Posted June 19 Posted June 19 (edited) Zumber, please explain what is exactly cold about the NC based fireworks? Edited June 19 by a_bab

It does NOT burn colder and it can still ignite flammable things. People die almost every year because of this stupid term.
Zumber Posted June 20 Posted June 20 They still can be hazardous if safe distance are not observed and the spark come into contact with flammable material.
