Range of connectors used for multipin or 'non-standard' connections. The small 3 pin Bulgin plug is used on the Le Maitre Pyroflash system. The larger 8-pin round 'truck plug' allows the connection of 6 dimmer circuits (up to 6A each) via a single multicore cable. This is ideal for carrying multiple dimmed circuits to a moving set-piece or truck. The 8-pin round connector has become a standard for disco lighting systems.

Pyrotechnic device, produced by Le Maitre, which is available as a cartridge which plugs into a flash pot, and when detonated, produces an intense cloud of coloured smoke. Care must be taken as the smoke contains a pigment which can stain light coloured objects or costumes.
Frozen solid carbon dioxide (CO2) at a temperature of -78.5° centigrade which produces clouds of steam-loaded CO2 gas forming a low-lying mist or fog when dropped into boiling water. Although non-toxic, caution is required in the storage and handling of dry ice because of its extreme cold. Water is boiled in a large tank offstage, into which the dry ice is lowered in a basket. Fans and ducts then direct the gas onto the stage. Dry ice does not support life, so care should be taken that small animals, actors etc.are not below the level of the dry ice for more than a few seconds.

Essential tools of the pyrotechnician's trade ! In the UK, they used to be colour-coded according to content (Carbon Dioxide (Black), Water (Red), Foam (Cream), Halon Gas (Green) Powder (Blue)) but now, they're all red with a small label saying what they are. Another great leap forward !.
A generic term for a pyrotechnic device consisting of a small cylindrical container into which pyrotechnic powder has been loaded. At the bottom of the container is an electric match or igniter which, when a large enough electrical current flows through it, produces a spark which ignites the powder. Many companies (such as Le Maitre and Theatre Effects) produce cartridge flash pots which are pre-loaded and sealed, reducing the likelihood of incorrect usage.
(Manufacturer) UK based manufacturer of pyrotechnic devices (Pyroflash brand name), smoke machines and other theatre effects

An electrically detonated pyrotechnic device giving the effect of a loud explosion. Made from gunpowder encased in stout cardboard or string. Must be used within a metal bomb tank. Originally developed in the second half of the 19th century to simulate the sound of cannon, it was often used to call out the volunteer lifeboat crew in an emergency.
(Pyro) Chemical explosive or flammable firework effects with a manual detonation. Usually electrically fired with special designed fail-safe equipment.
There are many different variations of pyrotechnic effects available. The categories are as follows:
Theatrical Flash - a flash and a cloud of smoke
Maroon: produces a very loud bang. Must only be detonated inside a bomb tank covered with a protective mesh.
Gerb: version of the Roman Candle firework, throwing a shower of sparks into the air. Possibly named from the French 'Gerbe' meaning a sheaf of wheat, due to it's shape.
All pyrotechnics should be used with close reference to local licensing laws, and the manufacturers instructions. Professional advice should be sought before the first use of effects.
Some territories only permit licenced pyrotechnicians to use these devices.
A pyrotechnic product which produces a cloud of real smoke when set alight.
