Which communication devices should you not use when contacting your supervisor?

• A. Landline phones
• B. Pens
• C. Cell phones, radios, or any other electronic device that could emit electromagnetic signals.
• D. Paper

Answer: (C)

Avoid using any electronic device that can emit electromagnetic signals when contacting your supervisor. In secure or high-risk environments, those signals can interfere with critical equipment, trigger alarms, or reveal your location, creating safety and security risks during incidents. That’s why the instruction targets cell phones, radios, or any other EM-emitting devices. Non-electronic tools like landlines, pens, and paper don’t emit such signals, so they align with procedures for maintaining controlled communications. Always follow your facility’s approved methods for reaching your supervisor.
