What is the principle of hierarchy of controls as it relates to TM 12A?

• A. Prioritizing training over equipment safety
• B. Prioritizing elimination, substitution, engineering controls, administrative controls, and PPE in that order
• C. Implementing controls without assessing risks
• D. Focusing solely on personal protective equipment

Answer: (B)

The principle of hierarchy of controls is a foundational concept in safety management and risk assessment, particularly relevant in contexts covered by Technical Manual 12A. This principle emphasizes a systematic approach to addressing hazards by prioritizing the most effective strategies for risk reduction. The correct understanding of this principle involves identifying and implementing controls in a specific order: first, eliminating the hazard entirely if possible; second, substituting the hazard with something less dangerous; third, using engineering controls to reduce exposure; fourth, applying administrative controls to manage how people interact with the hazard; and finally, using personal protective equipment (PPE) as a last line of defense. This order is vital because it focuses on removing the hazard or reducing risk at the source before relying on protections that depend on human actions, which can be less reliable. By following this hierarchy, organizations can ensure they are using the most effective means of safeguarding workers and minimizing potential incidents. Each step in the hierarchy is designed to progressively reduce risk more effectively than the less effective measures that follow it.
