Who is responsible for giving written authorization for spark-producing devices in explosives areas?

The correct choice is the Commanding Officer, as this role entails overarching responsibility for safety and operational decisions within a unit. When it comes to managing risks associated with spark-producing devices in explosives areas, the Commanding Officer ensures that all necessary precautions are taken to maintain safety. This individual holds the authority to evaluate the specific circumstances and potential hazards before granting written authorization, thereby effectively managing the safety protocols within their command.

In the context of explosives safety, the Commanding Officer collaborates with other officers, including the Safety Officer and Explosives Safety Officer, who provide input and recommendations. However, the final decision rests with the Commanding Officer, emphasizing their command responsibility and accountability for the safety of personnel and equipment in high-risk environments.
