Which engineering control is for emergency use only are usually installed inside rooms where antennas are located?

• A. Interlocks
• B. Kill Switches/Panic Buttons
• C. AZIMUTH BLANKING
• D. DUMMY LOADS

Answer: (B)

In safety design for high‑power antenna rooms, having a rapid, clearly marked way to shut things down is essential. Kill switches or panic buttons provide exactly that: an immediate means to cut power or RF transmission in an emergency, and they’re placed inside the room so a technician can reach them without delay. They’re intended for urgent use only, to stop hazards fast.

Interlocks are about preventing access or forcing safe conditions when a door opens, not about a quick manual shutdown during an emergency. Azimuth blanking isn’t a direct emergency control; it’s a method for managing antenna exposure, not an evacuation-style shutoff. Dummy loads are used to terminate RF when testing or when the antenna isn’t connected, not for stopping an active incident.
