Which item is NOT an engineering control for EMFR hazards?

• A. Azimuth Blanking
• B. Dummy Loads
• C. Interlocks
• D. Electric Shock

Answer: (D)

Engineering controls for EMFR hazards are design features aimed at reducing the worker’s exposure to electromagnetic fields, either by limiting the emitted radiation, absorbing it, or preventing access to it when it could be harmful. Azimuth blanking reduces exposure by suppressing or blocking the RF beam in certain directions or during specific times, so nearby personnel are less exposed. Dummy loads provide a safe sink for RF energy, preventing radiation from escaping into the surroundings when the system is operating or being tested. Interlocks act as safety barriers that prevent the system from emitting RF energy or access from dangerous areas while the system is not safely secured, stopping exposure before it can occur. Electric shock, on the other hand, is a hazard related to contact with live electrical parts and is addressed with electrical safety measures like insulation, grounding, and proper wiring. It does not reduce EMF exposure, so it is not an engineering control for EMFR hazards.
