Multiple Choice

Describe the hierarchy of controls and how it applies to training safety decisions.

The main idea is using a safety framework that reduces risk by addressing hazards at their source, not just protecting people after the fact. The hierarchy of controls orders protections from most to least protective: elimination, substitution, engineering controls, administrative controls, and PPE. In training safety decisions, you start by asking if the hazard can be removed entirely. If you can cancel or avoid a risky drill element, that’s best. If you can replace it with something less dangerous, that substitution step is next. If the hazard still exists, you look to engineering controls—physical changes to equipment or the environment that reduce exposure, such as barriers, guards, or safer setups. If the hazard can’t be eliminated through engineering, you implement administrative controls—clear procedures, training, supervision, pacing, and written rules to lower risk. Only after these steps do you rely on PPE to protect participants, since PPE doesn’t remove the hazard itself but rather provides a last-line shield. This approach ensures drills are as safe as possible by progressively removing or reducing risk, rather than depending solely on protective gear. The other options miss this layered approach: PPE-only relies on protection rather than reducing risk; administrative controls alone aren’t always sufficient; and substitution is about changing the activity to a safer form rather than, for example, replacing people.
