Security

The main requirements for the security of explosives are set out in:

• the Explosives Act 1875
• the Control of Explosives Regulations 1991
• the Marking of Plastic Explosives for Detection Regulations 1996

This legislation applies to anyone manufacturing or storing explosives for whatever purpose.

Explosives Act 1875

Section 23 of the Explosives Act requires that anyone storing explosives must take all due precautions to prevent unauthorised access to the explosives. Your licensing authority will be able to provide further advice.

Control of Explosives Regulations

The Control of Explosives Regulations 1991 (COER) cover all explosives used in commercial, military or leisure activities. This includes blasting explosives, detonators, fuses, ammunition, propellants, pyrotechnics and fireworks.

The main provisions of COER are:

• Anyone wanting to acquire or keep certain explosives must have an explosives certificate, issued by the police*
• Duties are placed on anyone wanting to transfer certain explosives to others*
• Anyone who has committed certain offences or been sentenced to certain terms of imprisonment must not acquire, keep, handle or control certain explosives or substances which could be used as explosives
• Occupiers of licensed explosives stores or magazines must appoint someone to be responsible for explosives security
• Comprehensive, accurate and up-to-date records must be kept of certain explosives*
• The loss or theft of explosives must be reported immediately to the police

* Controls on acquisition, transfer and record-keeping do not apply to sporting ammunition, fireworks or many pyrotechnic devices.

Explosives certificate

COER Schedule 1 lists the explosives that, together with smokeless powder, do not require an explosives certificate.

Contact your local police explosives liaison officer for further information on COER and on obtaining an explosives certificate.

Marking plastic explosives

The Marking of Plastic Explosives for Detection Regulations 1996 apply to all explosive substances commonly known as 'plastic explosives' – whether or not they are in explosive articles or devices, or in the form of flexible or elastic sheets.

The main provisions are:

• anyone making plastic explosives has to mark them, ie they have to add (to certain minimum levels) any one of four specified chemical substances chosen to aid detectability
• no one can possess, transfer or import any plastic explosives that are unmarked

The main exceptions are:

• Until 31 July 2012, there are certain specific exceptions for police and military users of plastic explosives
• The Regulations do not cover quantities sufficient for either researching, developing and testing new explosives or explosives detection equipment, or conducting forensic science
