Linking the Unplanned Explosions at Munitions Sites Database to the Global Framework on Ammunition

Submitted by Lionel Kosirnik on

Unplanned explosions at munitions sites (UEMS) pose challenges on a global scale as they can occur anywhere. Since 2009, the Small Arms Survey has developed and maintained a database on UEMS, totalling 674 incidents over the period 1979–2024 that resulted in more than 31,000 casualties. These incidents happened in 108 countries across every continent but Antarctica. UEMS generate public health and humanitarian costs, and have long-term socio-economic, financial, and environmental consequences.

Unplanned explosions at munitions sites (UEMS) are a significant safety threat for governments and a major challenge for the international community. A single UEMS incident can result in multiple casualties, millions of dollars' worth of damage to nearby buildings, infrastructure, and homes, as well as harm to the environment. Research conducted by the Survey reveals that these incidents are widespread and increasingly common: in its database, the Survey has recorded more than 674 incidents that occurred since 1979.

Unplanned explosions at munitions sites (UEMS) are accidental explosions of abandoned, damaged, improperly stored, or properly stored stockpiles of ammunition and explosives at munitions sites. UEMS are a persistent and global problem. They are a significant safety concern for the public and a major security challenge for states and societies. Addressing the challenge posed by UEMS requires not only putting in place effective stockpile management practices but also implementing a life-cycle management of ammunition (LCMA) system.

The explosions, at an army barracks, killed over 100 people and destroyed military buildings as well as people’s homes around the site. President Teodoro Obiang Nguema stated that the explosions were “caused by negligence of the unit in charge of storing explosives, dynamite and ammunition at the Nkoa Ntoma military camp”.
