When should SDZs be modified?

The selection that specifies when SDZs (Surface Danger Zones) should be modified is correct because changes in the training scenario, such as incorporating multiple targets or firing points, can significantly impact safety and risk assessments. Each unique setup can create different hazards depending on the location of targets, the angles of fire, and the potential for projectiles to travel outside designated safe areas. Therefore, to ensure the safety of all personnel involved and those in adjacent areas, it is essential to reevaluate and adjust the SDZs accordingly.

By modifying SDZs in response to changes in training dynamics, range officers can maintain compliance with safety protocols and mitigate risks effectively, ensuring a safe training environment. This practice also aligns with best safety management practices within firearms training operations.
