What is PSSM?
PSSM - physical security and stockpile management - comprises of procedures and actions that are necessary to ensure responsible and safe accounting, storage, transportation and handling of SALW and their ammunition.
International standards have been developed that provide guidance to state actors on the implementation of good practices in PSSM to enhance safety, security, and accountability: these are the International Ammunition Technical Guidelines (IATG) and the Modular Small-arms-control Implementation Compendium (MOSAIC).
These guidelines provide detailed information e.g. on the classifiction of ammunition and explosives according to the United Nations Hazard Classification system, the calculation of the blast perimeter and the therefore required minimum distance between an explosive storage facility and other infrastructure and civilian habitations to prevent material damage, injuries and casualties.
They also give detailed advice on topics such as weapons accounting, including inventory management – as the basis to identify losses or theft. Sound record-keeping also serves as a disincentive for such malpractices.
Effective PSSM enhances local, national, regional and international security as it reduces the risks of diversion, illicit trafficking, and accidental explosions.
