Precautions in electrical firing 63. When using electric detonators, the shot firer shall — (a) when any hole has been charged, keep on his person the operating handle or key of the shot-firing apparatus; (b) not connect the firing cable to detonator wires of any charge or charges until he has completed all firing preparations other than those referred to in paragraphs (c) and (d); (c) except when a photo-electric type of tester is used, not apply any electrical test to the firing circuit otherwise than through the firing cable and from a place of safety; (d) not connect the firing cable to the terminals of the shot-exploder or other firing apparatus until immediately before firing or attempting to fire; and (e) immediately after firing or attempting to fire, disconnect both leads of the firing cable from the shot-exploder or other firing apparatus, and there and then remove the operating handle or key of the shot-exploder or secure the locking arrangement of the shot-firing apparatus and remove the key. 64. Precautions after firing 64. After firing the shot firer shall — (a) except in the case of firing by electricity or with detonating fuse, count, in conjunction with at least one other person, the number of shots exploding, and, unless both he and such other person are certain that all the shots have been exploded, shall not enter or allow any person to enter the places in which the shots have been fired until the expiration of thirty minutes from the time of lighting the fuses; Page 26 Revised as at 6th day of May, 1997 c Explosives Regulations Regulation 65 (b) not approach a charge fired by an electric current which has misfired until after an interval of ten minutes, and provided that the conducting wires have first been disconnected; (c) not enter, or permit or instruct any person to enter, a place where charges have been fired until the fumes caused by the explosion have been dispelled; (d) personally examine the working place for misfires and dangerous ground, and until he has done so and has taken all reasonable steps to make the place safe, not allow any person except those necessary to assist him in making safe, to enter or approach such place; (e) examine every visible drill hole for unexploded explosives, using a copper scraper or wooden stick, and after such examination shall plug such holes with wooden plugs painted red; such plugs shall not again be removed except by himself and temporarily for the purpose of inspection, until he has charged the drill holes in the immediate vicinity; and (f) deal immediately with misfires as described in regulation 6. 65. Suspected misfires 65. Where there is not a good reason to believe that all the charges have fired — (a) if the firing was effected electrically, the circuit shall be tested again and an attempt made to refire the charge before it is approached by any person, and if the attempt fails, the leads shall be disconnected from the exploder and ten minutes shall be allowed to elapse before the charge is approached; or (b) if the firing was effected by safety fuse, the charge shall not be approached by any person until not less than thirty minutes has elapsed since the lighting of the fuse. 66. Misfires 66. In the case of a misfire, the shot firer shall be responsible for taking the following action — (a) no explosives, detonator, detonator wire or fuse shall be withdrawn from the hole; (b) if the bore hole is stemmed and undamaged, the stemming only shall be washed out by means of water under pressure or by compressed air and water applied through a blowpipe of a pattern approved by the Chief Engineer and a new primer inserted and the hole restemmed and blasted or, where water under adequate pressure is not available, the stemming only may be carefully scraped out by means of an instrument made of wood or copper and a new primer inserted and the hole re-stemmed and blasted; or c Revised as at 6th day of May, 1997 Page 27 Regulation 67 Explosives Regulations (c) a new hole shall be drilled parallel to, at least six inches deeper than and not nearer than three feet to the misfired hole, and such new hole shall be charged and fired and the explosives liberated from the misfired hole: Provided that if the direction of the borehole cannot be accurately ascertained, a surface charge may be used. 67. All clear signal 67. The shot firer shall give audible signal after the blasting operation is completed and the period of danger is past. Such signal shall be distinctive and easily distinguished from the warning signal made under paragraph (d) of regulation 60 (1). 68. No blasting operations in hours of darkness 68. No blasting operations shall be carried out between the hours of 6 p.m. and 7 a.m. unless with written authority from the Chief Engineer. PART XI - Dangerous Practices and Accidents 69.

Precautions to prevent accidents 70. During the conveyance, handling, storing, guarding or using of explosives, all persons so engaged shall take all due precautions for the prevention of accidents by fire, explosion or concussion and for preventing unauthorised, incompetent or unfit persons from having access to explosives, and shall abstain from any act which tends to cause fire, explosion or concussion and is not reasonably necessary in connection with such operations, and shall use every reasonable endeavour to prevent any other person from committing such act, and whoever, after being warned, commits any such act is guilty of an offence. 71. Reporting accidents 71.
