What action does IBD and PTRD primarily focus on?

The action that IBD (Installation and Base Defense) and PTRD (Propellant and Tactical Resource Division) primarily focus on is protecting people. Their core mission is centered around ensuring the safety and well-being of individuals who may be exposed to explosive hazards or risks associated with munitions. This involves implementing safety protocols, training personnel, and maintaining an environment that minimizes risks associated with explosive materials. By prioritizing the protection of personnel, these divisions help to ensure that operational readiness is maintained while simultaneously safeguarding lives.

Moreover, while other options like regulating fire hazards, managing ammunition storage, and assessing detonation risks are important aspects of overall explosive safety, the primary focus remains on the safety of personnel directly involved in handling and working around explosives.
