What is the appropriate action if a radio channel becomes overloaded during a mass incident?

• A. Switch to alternate channel or tiered communications per policy, and establish a dedicated channel for incident command.
• B. Defer communications until the channel clears.
• C. Increase power to extend range.
• D. Ignore and continue on current channel.

Answer: (A)

When a radio channel becomes overloaded in a mass incident, the priority is to keep critical command and operations communications clear. Following policy, you should switch to an alternate channel or use a tiered communications approach and establish a dedicated channel for incident command. This preserves a reliable path for command staff to issue orders, share situational updates, and coordinate with responders, even as traffic on the primary channel spikes.

Deferment or extending the same channel won’t help safety or coordination; the incident still requires timely information flow. Increasing power to extend range is not a valid solution here and can cause interference or violate equipment limits. Ignoring the overload and continuing on the same channel jeopardizes everyone’s safety and the effectiveness of the response.
