With mixed full-time & paid on-call, often the officer is the only engineer, so they have double duty. On anything of substance, the chief will probably arrive, but not always. So being able to hear the interior is important. Obviously, there are a lot of variations of staffing and radio needs. My view, as some others agreed, having the pump panel with more than a speaker and mic is important, for those that need/want a vehicle radio there.Interesting.
Our pump operators are only concerned about 1 thing... the guys at the end of the hose lines or incoming water. They aren't command, and they don't need to talk to anyone else. OIC in fact has multiple mobile radio's in the back of the command units for obvious reasons, at the pump panel not the case because the operator is always on the move and a headset is more effective in this position.
