A Duty Holder (DH) provides specific focus on safety and environmental protection management.

DHs have a personal duty of care for personnel under their command or management, for those who, by virtue of their temporary involvement in activities, come within a DH’s area of responsibility (AOR) and for the public who may be affected by their activities.

DHs are accountable for the safety of activities in their AOR and for ensuring that risks are reduced As Low As is Reasonably Practicable (ALARP).

In the execution of their specific responsibilities, DHs are accountable to Secretary of State for Defence (SofS), via their superior DH chain.
