  activities being performed.
• Downed Power Lines
• Unstable Structures and vehicles
• Hazardous Materials
• Other?

9
OTHER ASSESSMENT

• Victims outside vehicles (ejection)
• Hot and Cold zones around accident
• Size-up before beginning activity
• READ THE WRECK
• Additional Resources?
• Full protective equipment a must!!
• Set-up Tool Staging Area (Engine Operator or per
  dept. SOPs)
• Supplemental Safety Systems

HAZARD CONTROL

• Stabilize vehicles Create a safe platform for
  extrication work. Cribbing, struts, etc.
  Practical Activity
• Fire prevention and control pull and maintain
  charged, manned hoseline.
• Traffic Control Traffic control must always
  maintain radio contact with command or those
  working at scene.

12
Supplemental Restraint Systems

• 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.

13

• Static Electricity can cause air bags to deploy.
• 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

14

• Air Bag Deactivation Times Cutting the battery
  cables doesnt 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.
• Battery locations Vary based upon make, model.
  Batteries can now be found under hood, in the
  trunk, in the wheel well, and behind the rear
  seat.

15
Hybrid Vehicles

• Avoid ORANGE wires They are part of the high
  voltage system!
• Turn off ignition and remove key to render car
  safe.
• Remember, the SILENT CAR. It may be running and
  can move even if you dont hear it!
• High voltage systems are very safe.

16
Seat Belt Pre Tensioning

• Seat Belt Pre-Tensioner systems Designed to
  pull back seatbelt upon impact in coordination
  with airbag system. A part of the total SRS
  system.
• Normally found mid-height or near the floor in
  the door post. Contains an explosive charge
  similar to shotgun shell. Avoid cutting into
  this as it may go off.
