What is the cardinal principle of explosive safety defined as?

• A. Minimum number of people, minimum time, minimum explosives and agents
• B. Maximum number of people, maximum time, maximum explosives and agents
• C. Zero tolerance for any deviation from procedures
• D. Absolute prohibition of all explosive operations except authorized exceptions

Answer: (A)

The heart of explosive safety is to limit risk by cutting down three things that determine how severe an incident could be: how many people could be affected, how long they could be exposed, and how much explosive material is involved. Using the smallest crew necessary, conducting operations in the shortest practical time, and handling only the minimum amount of explosives and agents needed all work together to dramatically reduce the potential impact if something goes wrong. That’s why this option is the best fit: it directly targets reducing exposure, duration, and quantity to keep people and surroundings safer. The other ideas shift risk in the opposite direction or describe policy stances rather than the practical risk-control principle—maximizing people, time, or material increases risk; insisting on zero deviation isn’t the same defined principle; and prohibiting all work except certain exceptions is a policy approach, not the core safety guideline.
