Which administrative control involves continuous monitoring of exposure in a controlled EMFR area?

• A. Constant Observation
• B. Fences
• C. Interlocks
• D. Azimuth Blanking

Answer: (A)

Continuous monitoring of exposure in a controlled EMFR area is an administrative control that relies on a trained observer to watch real-time conditions and enforce exposure limits through procedures and supervision. This approach ensures that the area remains within allowable exposure, alarms and deviations are caught immediately, and appropriate actions—like restricting access or stopping work—are taken right away. It depends on human oversight and established protocols rather than altering the physical setup. Fences provide a physical boundary to prevent entry but don’t track or regulate exposure levels. Interlocks are engineering controls that automatically shut off or interrupt emissions when a barrier is breached. Azimuth blanking is a shielding/beam-control technique that limits emission in certain directions. None of these continuously monitor exposure like a designated observer does.
