Which components make up the cardinal principle?

• A. Maximum safety equipment, maximum time, maximum quantity.
• B. Minimum supervision, minimum paperwork, minimum training.
• C. Minimum number of people, minimum time, minimum amount of explosives or chemical agents.
• D. Protective gear, training, documentation.

Answer: (C)

The principle being tested is about reducing risk by limiting three exposure factors: who is involved, how long the hazard is present, and how much hazardous material is used. In practice, this means keeping the number of people to a minimum, shortening the time a hazard is active, and using the smallest practical amount of explosives or chemical agents. That’s why the best choice describes the minimum number of people, minimum time, and minimum amount of explosives or chemical agents. This approach directly lowers potential casualties, blast effects, and accidental releases by narrowing both the scope and duration of exposure. The other options talk about increasing safety gear or time/quantity, or rely on procedures like training and documentation, but they don’t embody the core aim of limiting exposure and material, which is central to the cardinal principle.
