4. Fire department response
We obtained data from The Office of the Fire Marshal related to responses by fire
departments in 2004. Fire departments responded to 33,082 motor vehicle “accidents”
and 2,618 vehicle extrications, not included in the previous number. In addition there
were 116 and 14 responses attributed to a vehicle “accident” and listed as fires with loss
and without loss respectively.
Most of these “accidents” are likely to be HTA reportable collisions. As a result,
we assign 35,830 responses by fire departments to motor vehicle collisions. We assume
that fire departments will respond to all fatal collisions with the remainder of calls going
to injury collisions. Exhibit A-15 shows this allocation and the factors used in the model.
