What is the minimum safe distance required from an impact area during training with high-explosive grenades?

The minimum safe distance required from an impact area during training with high-explosive grenades is 310 meters. This distance is critical to ensure the safety of personnel and equipment not involved in the training exercise. The distance is established based on the characteristics of the grenade's explosion and the potential risk of fragmentation.

Maintaining this distance minimizes the risk of injury from blast effects and shrapnel, which can travel considerable distances depending on various factors including the type of grenade being used and environmental conditions. Safety protocols are designed around this measurement to provide a buffer zone that ensures both personnel safety and operational integrity during training exercises.
