Authorised explosives

Fireworks that meet the requirements of BS7114 must also be included in a publication called the UK List of Classified and Authorised Explosives (LOCAL) and more recently by LOCAF (the UK List of Classified and Authorised Fireworks 1999). These lists originate from the Explosives Acts and relate to civilian rather than to military explosives. Thus, the 1994 edition of LOCAL contains articles ascribed to Kimbolton, Pains and Le Maitre. For example, included in the FIREWORKS columns, will be found STANDARD SET PIECE. For this particular entry, the United Nations Serial Number is given as 0336, the Hazard Code is 1.4G, the UK Class and Division is 7.2, while the Competent Authority (HSE) Reference is GB 72411.
