RESPONSE TO THE
l Follow all Dept. response policies
l Remember, this is NOT your emergency.
You have been called to assist someone else.

other activities being performed.
– Downed Power Lines
– Unstable Structures and vehicles
– Hazardous Materials
l Victims outside vehicles (ejection)
l Hot and Cold zones around accident
l Size-up before beginning activity
l “READ THE WRECK”
l Additional Resources?
l Full protective equipment a must!!
l Set-up Tool Staging Area (Engine Operator or per
l Supplemental Safety Systems
l Stabilize vehicles – Create a safe platform
for extrication work. Cribbing, struts, etc.
l Fire prevention and control – pull and
maintain charged, manned hoseline.
l Traffic Control – Traffic control must
always maintain radio contact with
command or those working at scene.
l Air Bags – Deployed or not? Location?
– Front Impact Bags – Do Not put yourself between
undeployed bag and patient.
– Side Impact Bags – Normally curtain type from ceiling
or side of seat mounted. Cylinder for systems normally
in A, B, or C post. Avoid!! Pull off trim to expose and
identify location before cutting.
– Rear seat bags – Newer high end cars.
– NO universal marking system. Most, however use
SRS, HPS, IC, SIPS, or “Airbag”.
l StaticElectricity can cause air bags to
l Remember the 5-10-20 Rule:
– 5” away from side air bags
– 10” away from steering wheel air bags
– 20” away from front passenger air bags
l Air Bag Deactivation Times – Cutting the
battery cables doesn’t always work! The
system can still hold a charge! Vary
depending upon make, model of vehicle.
Some older vehicles can hold a charge for
up to 20-30 minutes.
l Battery locations – Vary based upon make,
model. Batteries can now be found under
hood, in the trunk, in the wheel well, and
