WAC 212-17-370   Proximate display -- Definitions.  For the purpose of this section the following definitions are used:

     (1) Aerial shell. Usually a cylindrical or spherical cartridge containing pyrotechnic material, a long fuse or electric match wires, and a black powder lift charge.

     (2) Airburst. A pyrotechnic device that is suspended in the air to simulate outdoor aerial fireworks shells without producing hazardous debris.

     (3) Binary system. A two-component pyrotechnic system.

     (4) Black powder. A low explosive consisting of an intimate mixture of potassium or sodium nitrate, charcoal, and sulfur.

     (5) Comet. A pellet of pyrotechnic composition that is ignited and propelled from a mortar tube by a charge of black powder.

     (6) Concussion effect. A pyrotechnic effect that produces a loud noise and a violent jarring shock for dramatic effect.

     (7) Concussion mortar. A device specifically designed and constructed to produce a loud noise and a violent jarring shock for dramatic effect without producing any damage.

     (8) Electric match. A device containing a small amount of pyrotechnic material that ignites when a specified electric current flows through the leads. An electric match is used to initiate pyrotechnics. Electric matches are often incorrectly called squibs.

     (9) Fallout radius. A line that defines the fallout area of a pyrotechnic device.

     (10) Fixed production. Any production performed repeatedly in only one geographic location.

     (11) Flare. A pyrotechnic device designed to produce a single source of intense light for a defined period of time.

     (12) Flash pot. A device used with flash powder that produces a flash of light and is capable of directing the flash in an upward direction.

     (13) Gerb. A cylindrical preload intended to produce a controlled spray of sparks with a reproducible and predictable duration, height, and diameter.

     (14) Integral mortar. A preloaded mortar containing pyrotechnic materials and intended for a single firing only.

     (15) Lift charge. The composition in a pyrotechnic device that propels the effect into the air when ignited.

     (16) Manufacturer. An individual who performs the following:

     (a) Prepares any pyrotechnic material; and

     (b) Loads or assembles any pyrotechnic device.

     (17) Mine. A pyrotechnic device, usually a preload, that projects multiple pellets of pyrotechnic material that produce sparks or flame.

     (18) Mortar. A tube or pot-like device used to direct and control the effect of the pyrotechnic material.

     (19) Proximate audience. An audience closer to pyrotechnic devices than permitted by WAC 212-17-325.

     (20) Pyrotechnic device. Any device containing pyrotechnic materials and capable of producing a special effect as defined in the section.

     (21) Pyrotechnic material. (Articles pyrotechnic.) A chemical mixture used in the entertainment industry to produce visible or audible effects by combustion, deflagration, or detonation.

     (22) Pyrotechnic operator. (Special effects operator.) An individual who has responsibility for pyrotechnic safety and who controls, initiates, or otherwise creates special effects.

     (23) Pyrotechnic special effect. A special effect created through the use of articles pyrotechnic materials and devices. (See also special effects.)

     (24) Pyrotechnics. Controlled exothermic chemical reactions that are timed to create the effects of heat, gas, sound, dispersion of aerosols, emission of visible electromagnetic radiation, or a combination of these effects to provide the maximum effect from the least volume.

     (25) Rocket. A pyrotechnic device that moves by the ejection of matter produced by the internal combustion of propellants.

     (26) Saxon. A pyrotechnic device consisting of a tube that rotates around a pivot point to produce a circular shower of sparks.

     (27) Special effect. A visual or audible effect used for entertainment purposes, created exclusively by articles pyrotechnic.

     (28) Waterfall, falls, park curtain. An effect of a cascade of sparks usually produced by multiple devices fired simultaneously.

     (29) Wheel. A pyrotechnic device that rotates on a central axis consisting of multiple gerbs or rockets attached to a framework.
