What must occur if a round exits an approved SDZ during firing?

If a round exits an approved Surface Danger Zone (SDZ) during firing, local firing will cease until the cause of the round out impact is determined. This is critical for ensuring the safety of personnel and property beyond the designated impact area. The cessation of fire allows for a thorough evaluation of the situation to ascertain whether it was due to a malfunction, misfire, or any other unforeseen issue related to the firing. By halting the firing operations, safety measures are reinforced, preventing any potential accidents or injuries that might occur if firing were to continue under uncertain conditions.

In contrast, continuing to fire normally, resuming fire after a short pause, or only reporting the incident without taking immediate action could pose significant risks. These alternatives fail to prioritize the immediate assessment and rectification of the situation which is essential for maintaining a safe training environment.
