Anyone can shed light on the different duty the ambulances
responds to, the different uses of the strobe lights and the
sirens. Lastly, which ambulances are zoned to which hospital.
control will usually dispatch ambulances which are situated near
to the incident site, for example if A221 is located in stn with no
calls and there's an incident few meters away, this particular
ambulance will be dispatched but assuming if A221 is on call then
the next nearest ambulance will be dispatched..
bear in mind that SCDF ambulances can only en-route to the
nearest govt hospitals and NOT private hospitals, an example would
be ambulances from tampines fire stn & changi fire stn would
usually en-route to Changi General Hospital (CGH)..assuming the
call is regarding a child who is have fits, then the ambulance will
en-route to KK..
as for the strobe lights & sirens, every ambulance
dispatched for a 995 call will have their strobe lights on, sirens
would be used when motorists fail to give way and continuous
blaring of the siren means that its a standby case and every minute
counts..
