What is the correct order of the hierarchy of controls?

• A. Engineering, Administrative, PPE, Combination
• B. PPE, Administrative, Engineering, Elimination
• C. Administrative, PPE, Engineering, Elimination
• D. Elimination, Substitution, Engineering, PPE

Answer: (A)

The main idea here is how to reduce risk by prioritizing controls from most protective to least. The hierarchy of controls aims to remove or lessen exposure at the source first, so elimination and substitution come before any protection worn by people. If the hazard cannot be removed or replaced, engineering controls are used to redesign the work environment or processes to separate people from the hazard. If exposure can still occur, administrative controls change how work is done to reduce exposure, and PPE is used as the final line of defense. The option in question reflects a practical progression: start with engineering measures to modify the system, then use administrative controls to influence how work is performed, and rely on PPE when needed, while recognizing that a combination of controls is often employed to achieve adequate protection. This fits the test’s emphasis on layering protection and using multiple controls together, which is why it is considered the best answer. Other sequences tend to place PPE at the front or omit a key layer, which does not align with the protective intent of the hierarchy.
