This Joint Service Publication (JSP) is a guide to explain the requirements needed to demonstrate that the inherent risks from Ordnance, Munitions and Explosives (OME) are either broadly acceptable or tolerable and as low as reasonably practicable (ALARP) for the MOD, third parties and the environment. JSP 520 applies to all ordnance (weapons, delivery platforms), munitions (missiles, shells, pyrotechnics, mines, bullets, explosive charge) and explosives (propellants, energetic material).

This JSP is to be used by personnel responsible for OME employed by or contracted to the MOD, land, maritime, air and third parties.
