Which three elements are described in the Cardinal Rule for safe operations?

• A. People, time, and explosives
• B. People, money, and equipment
• C. Time, money, and space
• D. Explosives, pallets, and containers

Answer: (A)

The main idea is that safe operations hinge on controlling three factors: people, time, and explosives. In explosives handling, safety comes from who is present, when activities take place, and what explosive material is involved. Limiting who is in the work area (trained personnel only) reduces exposure to risk. Scheduling activities carefully and minimizing rushed timing reduces chances of mistakes or accidents. Controlling which explosives are being used and ensuring proper handling and storage reduces the chance of unintended initiation. These three elements—who is present, when things happen, and which explosives are involved—are what the Cardinal Rule emphasizes. The other options mix in money, equipment, space, pallets, or containers. While those can influence safety, they are not the three elements singled out by this Cardinal Rule in the context of safe operations.
