At least one member of every interior firefighting team should be equipped with this specific instrument for communication:

Effective communication is crucial during interior firefighting operations due to the hazardous and chaotic environment. A two-way radio allows for continuous and reliable communication between team members and command. This instrument enables fire personnel to relay real-time information about conditions, hazards, and any changes in the situation, which is essential for maintaining safety and coordinating efforts among team members.

In addition to facilitating direct voice communication, a two-way radio can also help share critical status updates, such as the progress of operations or any need for assistance. As firefighters are often operating in low visibility and high-stress conditions, having a means of communication that allows for prompt responses and immediate updates is vital for the successful management of the incident and the safety of all personnel involved. This is why ensuring that at least one member of every interior firefighting team is equipped with a two-way radio is a key protocol in firefighting operations.
