Mk 2 Mod 0

General: The firecracker is used as a practice charge for booby traps and firing de-vices. It produces a loud report accompanied by a bright flash and a considerable quan-tity of smoke, yet it is designed to reduce the hazard from flying particles such as are attendant upon the use of a standard potassium perchorate firecracker or flash salute. The Firecracker Mk 2 Mod 0 contains no high explosive. It is coated with a waterproofing material, yet it should be stored in a dry place.

Installation: The nipple of the coupling base of any standard firing device is pushed through the wax-filled hole in the hollowed end of the firecracker and rotated clockwise until at least two threads of the coupling base are inside the hollowed end.
