So if they're dispatched to an interstate MVA, how does this save money and time on the response? Do they just go, do the extrication, then pack up the patient and all their gear and leave?
The typical response that 46 was talking about is a reported interstate MVA at X mile marker, westbound would get a rescue engine or rescue company and a medic going east AND the same response going west, given the unique traffic woes of the NOVA area. Whoever gets access to the scene first is the one that handles the call.
The cost of a rescue truck is considerably less than an engine. The unit is set up to be as autonomous as possible. An interstate MVA would get a rescue company. If there was a report of fire it would also get an engine and a truck as well.
Once on scene if the situation required, additional resources could be called. With the exception of a few certain areas during peak traffic, the response delay wasn't appreciable.
But in my time there, extra help was usually a truck company (brings more men, equipment, can sweep stuff off the road and makes a fine road block) or an ambulance (ambulance so alternate hospitals could be used so as not to flood one ED or to clear the rescue company if it was a busy day for fires or people getting themselves stuck in amazing ways.)
With the capability to extricate and transport multiple patients at once, there isn't need to call for help often on an MVA. (But it does happen occasionally like when somebody plows a car into a house and the structure needs to be stabilized.)
If the rescue was capable of handling the situation it would be the only unit utilized. Even being manpower heavy, it reduces the need to send multiple units on a regular basis. Less maintenence, less fuel, etc.
If you send 1 rescue, you send max 8 guys. 1 vehicle.
If you respond with an engine, (4-5 people) a truck, another 4, and a medic, 2 you would have 10 people average, and 3 vehicles. With the capability to transport only 2 patients.
The situation you described is sending 4 units. How many are often cancelled?
Also from the economic point and my opinion, a rescue pumper is a terrible waste of money. Too much gear, plus a pump, and usually some water. All that will need replaced one day.
You also get more skill dilution. I think there is more proficency to have a couple of medics who perform rescue and truck operations all day then it is to have a couple of medics who have to perform engine, truck, and rescue operations. You just get better at what you do.
I realize everyone does stuff different, because they have different needs, so there is no right or wrong, but it doesn't change the fact that the more stuff you send, the more it costs per incident, and the more you need to handle your volume. The system I was at might not work for your area, but it is always good to compare and share.
Perhaps we should talk about fire ops via PM. This isn't really the forum.
