(d) that appropriate steps are taken to prevent theft of the explosives and detonators or their initiation by an unauthorised person.

11 Prohibited shots
1 No person shall charge or fire a shot at a quarry—
(a) between one hour after sunset and one hour before sunrise;
(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 10(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 getting minerals or products of minerals (a “heading blast”), but this sub-paragraph shall not apply to any quarry at which heading blasts were used at any time during the period of 2 years immediately preceding the coming into force of these Regulations.
