In order to not tie up normal radio frequencies, some technical rescue teams do what instead?

Using small, talk-around radios is an effective strategy for technical rescue teams to manage communication without occupying regular radio frequencies. This approach allows for immediate, local communication among team members without interfering with broader operational channels that other first responders might be using.

The advantage of small, talk-around radios lies in their capacity for short-range communication. This is especially useful in environments where rescues are conducted in confined spaces or areas with complicated layouts, ensuring that team members can stay in contact without causing congestion on primary emergency channels.

While relying on training and minimizing verbal communication could enhance efficiency, it may not always be practical or safe in high-pressure situations where clear communication is paramount. Other channels could help in reducing frequency congestion, but they may not always be readily available or could still lead to confusion if not managed properly. Using cell phones, although it seems like a straightforward solution, can present challenges such as signal loss in certain environments, which can hinder coordinative efforts during critical rescue operations. Thus, the use of small, talk-around radios stands out as a deliberate choice to enhance communication effectiveness while preserving the integrity of standard radio frequencies used in emergency response.
