ABSTRACT: This paper describes a method for determining the velocity of fragments produced when firework maroon shells explode. Fragment velocities for shells fired in free air and in steel mortar tubes (causing them to rupture) are reported. velocity of plastic shell casing fragments that was recorded (964 m/s) was substantially higher than that measured for steel mortar fragments (512 m/s). The magnitude of the velocities measured indicates the potential hazard associated with these fragments and the need to consider methods of reducing such hazards.
