Deployment
Ambulances may be staffed by two Emergency Medical Technicians, one Emergency Medical Technician and one paramedic or, rarely, two paramedics. There is also at least one "Chase car" staffed with a paramedic at any given time. Additional Chase-cars are staffed as need dictates. 2010 policy revisions state there must always be one supervisor per operations division but currently no more than two are ever on duty simultaneously. This leaves at least one division without a supervisor on a recurring basis.
