When responding to a bomb threat, which equipment may be used?

• A. Mounted long-range cameras or non-electrical communication devices such as landline phones, pens, pencils, and paper.
• B. Batteries and flashlights.
• C. Personal mobile devices.
• D. Wireless radios.

Answer: (A)

In a bomb threat situation, the priority is to minimize anything that could interact with a device or create dangerous signals, while still enabling you to observe and communicate safely. Relying on equipment that is fixed, wired, or non-electrical helps achieve that. Mounted long-range cameras, if part of the facility’s existing wired surveillance setup, allow you to monitor from a distance without introducing new portable electronics into the danger zone. For communication, using non-electrical tools like landline phones (which are wired) and writing materials such as pens, pencils, and paper lets you relay information without generating electrical or radio-frequency emissions.

Portable or battery-powered devices—such as batteries with flashlights, personal mobile devices, or wireless radios—can emit signals or require power that could interfere with a detonator or complicate the response. They also pose additional safety and security risks in a threat environment. So the best-fit approach is to use fixed or non-electrical equipment and established wired communication methods.
