What is the first rule to follow when planning an explosive operation?

The primary focus of any explosive operation is the safety of personnel involved, which is fundamental to the first rule of planning such operations. By emphasizing the exposure of the minimum number of people to the minimum amount of explosives for the minimum amount of time, the objective is to reduce potential hazards and risks. This principle prioritizes safety by ensuring that there are fewer individuals in proximity to explosives and limits the exposure duration, thus minimizing the risk of accidents or injuries.

This rule underscores the importance of careful planning and risk assessment in order to protect personnel while accomplishing mission objectives. By adopting strategies that concentrate on reducing exposure, the operation can be conducted more safely and efficiently.

The other options touch on safety and operational procedures but do not encapsulate the overarching principle of minimizing risk through personnel management and exposure time as effectively as the chosen answer.
