During a search, what is the guideline regarding radios and mobile devices?

• A. Do not communicate with radios or other mobile electronic devices until a search area is cleared.
• B. Use radios continuously to coordinate the search.
• C. Keep devices on but set to silent.
• D. Only use landline telephones.

Answer: (A)

In a search within a hazardous environment, controlling ignition sources and preventing contamination spread is essential. Radios and mobile devices are electrical equipment that can become ignition sources in flammable atmospheres and can carry contaminants from the hot zone to clean areas. So the guideline is to avoid using these devices in the search area until it has been cleared and deemed safe. This reduces the risk of ignition and helps keep the team focused, while allowing coordination to resume from outside the hazard once the area is considered safe. Using radios continuously would keep an unnecessary ignition risk and create noise and distraction in the field. Keeping devices on but silent still leaves the potential for accidental transmissions or alarms. Relying only on landline telephones ignores the practical needs of field operations and doesn’t address the ignition risk within the search zone.
