To protect against accidental firing, all electrically fired pyrotechnic devices shall be shunted at all times prior to firing. Power sources for firing pyrotechnic special effects devices shall be restricted to isolated batteries or individually isolated, ungrounded generators used for firing purposes only. Commercial or house power may only be used providing the firing system is electrically isolated from the commercial or house power through the use of such items as isolation transformers. Under no condition may commercial or house power be used directly for firing purposes. There should be no radio transmissions in the area where electrically fired pyrotechnic devices are being used.
Static electricity is specifically a problem during periods of low humidity.
Intoxicating liquids, narcotics and other controlled substances shall not be used by any person handling pyrotechnic special effects at any time during their transportation, set-up, firing or removal.
