(4)     A single shot or round of shots being fired by the combined operation of an electrically fired detonator and detonating fuse shall be treated as a miss-fire after the shot firer, having attempted unsuccessfully to fire the detonator, has followed the procedure described in paragraph (2).

57      Partial miss-fires

(1)     A single shot or a round of shots being fired by either the method described in Regulation 56(3) or the method described in Regulation 56 (4) shall be treated as a partial miss-fire if, after detonation has taken place, the single shot or any shot in the round of shots, as the case may be, fails to explode.

(2)     A single shot or a round of shots being fired by the combined operation of igniter cord and safety fuse shall be treated as a partial miss-fire if, after the shot firer has withdrawn after once lighting or attempting to light the igniter cord, the single shot or any shot in the round of shots, as the case may be, fails to explode.

58      General precautions – miss-fires

In the event of a miss-fire, no person shall approach the shot hole or place where the charge was placed until, –

60      Drilling near miss-fires and partial miss-fires

(1)     Any person drilling a hole near a miss-fire or partial miss-fire shall ensure that the hole is drilled in such a manner as to avoid touching or otherwise affecting any unexploded detonator or charge.

(2)     Following a miss-fire the leads or fuse of the detonator shall be attached by a string to the shot firing cable or to some distinctive marker.

61      Dislodging of miss-fires and partial miss-fires

Whenever any detonator and/or unexploded charge has been or may have been dislodged by the firing of another shot a search shall be made by the shot firer for the detonator and/or charge before any worker resumes work and before any further shot is fired at or near that place.

62      Warning of miss-fires and partial miss-fires

In the event of a miss-fire or partial miss-fire, the shot firer concerned shall forthwith give, or cause to be given, warning of the miss-fire or partial miss-fire to all persons approaching or likely to approach the shot hole or place where the charge was placed (as the case may be) and, where the shot firer is not also the appropriate person, notice thereof to the appropriate person.
