Who is the lowest deviation authority authorized to approve deviations for allowing non-participating personnel within the SDZ?

The authority to approve deviations for allowing non-participating personnel within the Surface Danger Zone (SDZ) is vested in the Senior Commander with a rank of O-7 or higher. This rank signifies a high level of responsibility and oversight, ensuring that any decisions made regarding deviations are taken with the utmost consideration for safety and the potential risks to personnel. The role of a Senior Commander involves comprehensive risk assessment and the capability to implement necessary measures to mitigate danger, which aligns with the responsibilities needed when approving such deviations. This level of authority reflects both the experience and required understanding of the operational environment necessary to make informed decisions regarding safety protocols.

Other positions listed, while important within the range safety structure, do not hold the same level of authority and responsibility as the Senior Commander. The Range Control Officer, Brigade Commander, and Unit Safety Officer all have pivotal roles in range operations and safety management but do not possess the same rank or overarching authority to sanction deviations within the SDZ under the established regulations.
