What is the minimum withdrawal distance, in feet, for HD 1.3 explosives?

Explanation:
Withdrawal distance is the safety buffer you must stay behind from an explosive to avoid injury from blast, fragmentation, and thermal effects if detonation occurs. For HD 1.3 explosives, safety guidelines specify a minimum protective distance based on how far those hazards can reach under typical conditions. The correct option aligns with that standard minimum distance for this category of material, reflecting the level of protection that the hazard- distance table designates as the lowest acceptable withdrawal. The other figures either don’t meet that required protection or go beyond what the standard minimum prescribes. In real use, you’d consult the hazard-distance chart for the exact payload and configuration to confirm the precise distance.
