The fire extinguisher is not just for show
What else is the medic going to do? every call, regardless of nature, gets an response of an ALS capable ambulance. if the call is ALS the medics rides in the back. if it's BLS, the EMT does. if it starts BLS and goes ALS, the crew can switch positions.Do they have a rationale for this? I get wanting every patient to have an ALS assessment/triage to BLS, but do they really need to have medics driving around BLS calls? Seems like a waste of money.
As for the rationale for having an all ALS ambulance system vs a tiered system, that was waaaaay above my pay grade.
