Why should you not use cell phones, radios, or other electronic devices during a bomb threat?

• A. They could reveal your location.
• B. These may create a spark.
• C. They could jam communications.
• D. They could fail to function in a threat environment.

Answer: (B)

Electronic devices near a suspected bomb can act as an ignition source. Switches, batteries, or RF transmissions can create a tiny spark or arcing, and many explosive devices are designed to be sensitive to such ignition sources. Because a spark could set off the detonation, the safest practice is to avoid using cell phones, radios, or other electronics in the area. While concerns like revealing your location or interfering with communications can matter in other contexts, the immediate safety risk here is the potential for a spark to ignite the device.
