Which of the following is NOT an administrative control for EMFR hazards?

Which of the following is NOT an administrative control for EMFR hazards?

• A. Training
• B. Interlocks
• C. Safe Work Practices
• D. Fences

Answer: (B)

The main idea here is telling apart administrative controls from engineering controls for reducing exposure to non-ionizing radiation (EMFR hazards). Administrative controls involve policies, procedures, training, and scheduling—things that rely on people to follow them. Engineering controls are physical changes or devices that reduce exposure regardless of behavior, like barriers or automatic safety devices. Training and Safe Work Practices are classic administrative controls because they rely on workers’ knowledge and actions to minimize risk. Fences are physical barriers that limit access, which makes them engineering controls. Interlocks are devices built into equipment or access points that automatically prevent operation or exposure when a condition isn’t safe, which is also an engineering control. Therefore, the option that is not an administrative control is the one involving a device that automatically restricts access or shuts off the hazard. Interlocks fit that role, as they enforce safety through a physical mechanism rather than through policy or training alone.
