Actually I think there are different points being raised here. Its a valid thread. He's not doing the POV vs Rig debate but trying to address some specific concerns about the mechanics of how different agencies implement the procedures they have chosen.
To answer your question about the pager vs radio, different systems have determined different policies. If the vollies are extra manpower, provding supplemental personnel to a paid department or a station that has shifts staffed on site, the policies are going to be very different from the more rural districts where staffing a station just isn't feasible.
In our agency, until you have completed a communications class, no radio, just a pager. We are toned out on a radio with the call address. Whoever is closest to the pt generally will respond directly to the scene. For example, a call yesterday. Call is in the middle of the district. There are two volunteers who live less than a mile from the call. The first responding vol. radios..'Dispatch... 406 responding to ...call address....' Second responding vol. knowing this is a weekday morning and less likely to have a bunch of vol.s responding radios "Dispatch, 4161 responding to Station 1" This lets everyone listening know that she's going to the station to get the ambulance. I'm pulling into the station, because I just happened to be driving past it when the tones went off. I know this volunteer lives on the same road as the call, so I radio.. "4161 from 403. Am arriving Station 1, what is your ETA?" She responds... "4161 divierting to the call address."
It ended up just being the three of us on scene. So, the two first on scene did pt care and transported the pt via the ambulance I drove to the scene to the hospital. I then drove the first vollies car back to the station, got a ride back to the scene and drove the second rig back to the station, put their keys inside the locked station, filled out the call log and then got into my car and drove home.
We do need communication between volunteers because of those types of scenarios which happen frequently. Our district is very spread out with limited roads through it.
My husband works in a paid department. In their system the volunteers are only given pagers. They are instructed to go to the station when they are toned out. They have a staging area within the station where they standby until directed to respond. No need for these volunteers to carry a radio. A pager is perfectly sufficient to their needs. So, is a radio or a pager best? Depends on the situation... same for the POV/Rig debate.. there isn't one solution for every situation.
