Under 30 CFR 7.4 and 15, MSHA tests
and approves blasting units and explosive materials as permissible
for use in mines, respectively. Under 30 CFR 57.22606(a), mine
operators of Category III metal and nonmetal mines must notify the
appropriate MSHA District Manager of all nonapproved explosive
materials and blasting units prior to their use. Explosive
materials used for blasting must be approved by MSHA under 30 CFR
part 15, or nonapproved explosive materials must be evaluated and
determined by the District Manager to be safe for blasting in a
potentially gassy environment. The notice must also include the
millisecond-delay interval between successive shots and between the
first and last shot in a round.
