(v)ensuring, so far as is reasonably practicable, that such rules and procedures are complied with;

(b)an adequate written specification (whether produced by him or not) is prepared for each shotfiring operation at the quarry to ensure, so far as is reasonably practicable, that when such firing occurs it will not give rise to danger; and

(c)a copy of the specification referred to in sub-paragraph (b) is given to any person upon whom it imposes duties.

(3) The operator shall ensure that operations involving the storage, transport or use of explosives are carried out by—

(b)a trainee under the close supervision of a duly authorised and competent person.

(4) The operator shall ensure that—

(a)such facilities and equipment as are necessary to enable shotfiring operations to be carried out safely are provided;

(b)any vehicle which is provided for use in relation to shotfiring operations is so marked as to be readily identifiable from a distance;

(c)detonators are stored in separate containers from other explosives; and

(d)explosives are kept at all times either in a locked explosives store or under the constant supervision of a suitable person.

(5) The operator shall ensure, so far as is reasonably practicable, that each shotfiring operation is carried out safely and in accordance with the rules required to be made in pursuance of paragraph (2)(a) and any specification required to be prepared in pursuance of paragraph (2)(b).

Supervision of shotfiring and trainee shotfirers and records of appointment

5.—(1) The operator shall take all reasonable steps to ensure that—

(b)all shotfiring operations are carried out under the close personal supervision of the shotfirer.

(2) The operator shall ensure that a record of the appointment at the quarry of any shotfirer or trainee shotfirer is kept at a suitable place until three years after that shotfirer’s employment or trainee shotfirer’s employment at the quarry ends.

(2) A person shall not bring any substance or article (other than explosives) likely to cause an unintended explosion or fire within ten metres of any explosives or take any naked flame within ten metres of any explosives.

(3) A person shall not forcibly remove any detonator lead or other system for initiating shots from a shothole after the shothole has been charged and primed.

(a)unless there is sufficient visibility to ensure that work preparatory to shotfiring, the shotfiring operation and any site inspection after the shot is fired can be carried out safely;

(b)in a shothole which has previously been fired, unless he is dealing with a misfire in accordance with action taken in pursuance of regulation 7(b); or

(c)in any tunnel or other excavation (not being merely a shothole) in the face or side of the quarry for the purpose of extracting minerals or products of minerals.

(5) A person shall not fire a shot—

(a)unless he is a shotfirer or trainee shotfirer; and

(b)other than by means of a suitable exploder;

and for the purpose of this regulation, a safety fuse shall not be deemed to be a suitable exploder.


9.—(1) Subject to paragraph (2), the Secretary of State may, by a certificate in writing, exempt any quarry, part of a quarry or class of quarries, any person or class of persons or any operation or class of operations from all or any of the prohibitions and requirements of these Regulations, and any such exemption may be granted subject to conditions and to a limit of time and may be revoked at any time by a further certificate in writing.
