Part 33 Explosives Safety

Section 486 Bootleg

A bootleg is a portion of a drill hole or bore hole that has not been destroyed after detonation of an explosive charge. It may or may not contain explosives. Examination of the bootleg helps to determine if it contains explosives that could cause problems.

When a misfired explosive is discovered in a bootleg, it must be blasted to eliminate it from detonating unexpectedly at some future time.
