It gives practical advice on how to comply with the law. If you follow the advice you will be doing enough to comply with the law in respect of those specific matters on which the Code gives advice. You may use alternative methods to those set out in the Code in order to comply with the law. However, the Code has special legal status. If you are prosecuted for a breach of health and safety law and it is proved that you did not follow the relevant provisions of the Code, you will need to show that you have complied with the law in some other way or a court will find you at fault. The Regulations and the Approved Code of Practice (ACOP) are accompanied by guidance which does not form part of the ACOP. Following the guidance is not compulsory and you are free to take other action. However, if you do follow the guidance you will normally be doing enough to comply with the law. Health and Safety inspectors seek to secure compliance with the law and may refer to this guidance as illustrating good practice.

The Code of Practice comes into effect on 1 December 2006. Signed D.J. Breen Deputy Chief Executive of the Health and Safety Executive for Northern Ireland 24th November 2006 vi Introduction What is this publication about? 1. This publication provides guidance on how to comply with the Manufacture and Storage of Explosives Regulations (Northern Ireland) 20061 (MSER(NI)) which cover the manufacture, storage and handling of all explosives, including: (a) blasting explosives; (b) propellants; (c) detonators and detonating cord; (d) fireworks and other pyrotechnic articles; (e) ammunition; and (f) other explosive articles such as air bags and seat belt pre- tensioners. 2. The activities covered by MSER(NI) include the manufacture of explosives and intermediate products for on-site mixing and storage. 3. Also covered are handling operations that are not in themselves considered to be “manufacture”. These include: (a) fusing fireworks; (b) assembling fireworks displays from components; and (c) filling shotgun cartridges and other cartridges for small arms. 4. The Regulations do not cover the use or off-site transport of explosives. Who is this publication for? 5. This publication contains material that is relevant to everyone involved in any of the activities described in paragraphs 1-3. Other legislation 6. There are also other general health and safety regulations which apply to the manufacture, storage and handling of explosives. This document gives additional guidance where there are particular issues which need to be considered, for example selecting work or personal protective equipment. 1 Note on terminology 7. The following terms are used in this document: ‘communication’ - the process of deflagration or detonation progressing to adjacent or nearby explosives; ‘deflagration’ – exothermic chemical decomposition of a material in which the reaction front advances into the unreacted material at less than the speed of sound; ‘detonation’ – a chemical reaction that progresses through an explosive at a rate exceeding the speed of sound in the reaction zone; ‘explosives area’ - any area, which may be outdoors or within a building, where explosives are processed or stored; ‘explosives building’ - any building in which explosives are processed or stored; ‘explosives site’ - the whole area covered by the establishment. This is likely to be the same as the area covered by the explosives licence; ‘Hazard Type’ – defines the nature of the hazard arising from an explosive in manufacture and storage conditions (see paragraph 10 and Annex 1 for detailed guidance); ‘initiation’ – the act of causing an explosive
