During a bomb threat, which devices should be turned off within 300 feet?

• A. Radio only
• B. Phone only
• C. Neither radio nor phone
• D. Radio and phone

Answer: (D)

When a bomb threat is being handled, a key safety practice is to minimize any energy sources that could potentially trigger or influence an explosive device. Radios and phones are common sources of electromagnetic energy and electrical activity in the area around a suspected device. Turning off both a radio and a phone within 300 feet helps reduce the chance that RF energy or a spark could initiate the device, and it also reduces potential interference with emergency operations. Since either device could pose a risk, the safest approach is to power down both.
