Which option best names the Cardinal Principle of Explosives Safety?

• A. A guideline about worker training
• B. A guideline about storage containers
• C. A rule requiring frequent inspections
• D. Cardinal Principle of Explosives Safety

Answer: (D)

The question tests your ability to identify the formal name of the overarching safety principle in explosives handling. The Cardinal Principle of Explosives Safety is the official label used to describe the fundamental rule guiding all safety practices in this area. It isn’t describing a specific guideline about training, storage containers, or inspections—those are individual guidelines or procedures within a safety program. Since the question asks for the name itself, the option that literally states the Cardinal Principle of Explosives Safety is the best answer.
