Display pyrotechnics, 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.
The pyrotechnician FOC has three levels: pyrotechnician (which allows work under a supervisor), supervising pyrotechnician, and special effects pyrotechnician (which allows the fabrication of certain types of pyrotechnic devices). Additionally, a special effects pyrotechnician can be endorsed for the use of detonating cord.
Pyrotechnic initiators are often controlled electrically (called electro-pyrotechnic initiators), e.g. using a heated bridgewire or a bridge resistor. They are somewhat similar to blasting caps or other detonators, but they differ in that there is no intention to produce a shock wave. An example of such pyrotechnic initiator is an electric match.
The NASA Standard Initiator (NSI) is a pyrotechnic device used to set off other pyrotechnic devices. It is the central multi-purpose component of a modular system of detonating cords, pyrotechnics and various other explosive charges with many different uses.
For example, the US Environmental Protection Agency has studied the impacts of perchlorate on the environment as well as drinking water. [36] California has also issued guidance regarding perchlorate use. [37] US courts have taken action regarding the use of perchlorate in manufacturing pyrotechnic devices such as flares.

A basic pyrotechnic device. A gerb is a type of firework which produces a jet of sparks, usually lasting between 15 and 60 seconds.It is a thick-walled tube filled with pyrotechnic composition and possessing a choke, which is a narrowing in the tube.
A party popper is a handheld pyrotechnic device commonly used at parties. It emits a loud popping noise by means of a small, friction-actuated explosive charge that is activated by pulling a string. [1] The explosive charge comes from a very small amount of Armstrong's mixture (a highly sensitive explosive) in the neck of the bottle-like shape. [2]
