The Defence Ordnance, Munitions and Explosives (OME) Safety Regulator (DOSR)
Part of the Defence Safety Authority (DSA), the Defence Ordnance, Munitions, and Explosives (OME) Safety Regulator (DOSR) regulates the health, safety and environmental protection (HS&EP) of activities involving ordnance, munitions and explosives, military lasers, and major accident control across defence.
What we do
The DOSR regulates OME safety and environmental protection across defence. Our aim is to support safe defence capability by regulating activities involving ordnance, munitions and explosives and promoting continuous improvement in safety and environmental protection performance. We provide regulation, assurance and specialist advice in its areas of responsibility:
- acquisition of ordnance, munitions and explosives (OME)
- in-service and operational OME safety
- explosives licensing and storage
- defence-licensed explosives facilities
- hazard classification of military explosives
- MOD ranges used for trials and live-fire training
- Fieldcraft Training Areas (FTAs)
- military laser systems
- directed energy weapons
- control of major accident hazards on defence establishments (Major Accident Control, MACR)
The DOSR conducts risk-based, third Line of Defence (3LOD) assurance activities to secure compliance with their regulations and to contribute to the overall assessment of HS&EP in defence. We are also empowered to take regulatory enforcement action where necessary, to restore compliance with defence safety and environmental protection regulations and requirements.
Additionally, the DOSR works closely with the UK Health and Safety Executive and other defence regulators to ensure a coordinated approach to safety and environmental protection across defence.
