Which NFPA 70E section defines the Hierarchy of Risk Control Methods?

• A. 110.3(H)(3)(3)
• B. 120.6
• C. 105
• D. 111

Answer: (A)

The main idea here is how to manage electrical hazards most effectively by using a prioritized set of controls. The Hierarchy of Risk Control Methods is a structured approach that starts with eliminating the hazard or isolating it, then substituting something less hazardous, followed by engineering controls, administrative controls and safe work practices, and finally using PPE as a last line of defense. NFPA 70E codifies this approach in a specific section, which lays out the order and types of controls to consider and reinforces that higher-level controls should be used before relying on PPE or procedural fixes. Recognizing this hierarchy helps you plan tasks so you address risk at its source and layer protections appropriately. Understanding this section also clarifies how it fits into the overall electrical safety program: it guides decisions on how to perform work, what controls are feasible for a given task, and how to sequence protective measures. Other parts of NFPA 70E cover related topics such as training, establishing an electrically safe work condition, arc flash boundaries, and PPE categorization, but they do not define the hierarchy itself. NFPA 70E section 110.3(H)(3)(3) is the part that defines the Hierarchy of Risk Control Methods.
