Vehicle Extrication
Extrication is a process of removing
a trapped occupant from a vehicle that was involved in a
collision. Rescuers use tools, some specialized, and
technique to stabilize and cut apart a vehicle to free
the patient.
We train on the many elements of auto
extrication. The new technologies that are being designed into
vehicles to save fuel and protect the occupants have created
some new concerns for rescuers. In hybrids, high voltage
batteries and cables run throughout these vehicles that create
new dangers to rescuers. Supplemental restraint systems such as
seatbelt pre-tensioners and airbags have evolved into a very
advanced system. Vehicles today can have as many as 12 airbags
and numerous compressed air cylinders hidden beneath the
interior panels.
Knowing how a vehicle is designed has
become an ever-changing issue that we invest a lot of time in
studying. Rescuers must know where to safely approach a vehicle
to remove a victim without causing further harm to the patient
or themselves.
When rescuers respond to a crash scene,
they consider the time of day, weather conditions and the
location. These are important concerns that can help crews
anticipate the crash results. Wet roads, high speed limits, or
deep roadside ditches can dramatically affect the severity of a
crash.
Once on scene, crew will observe the entire
site to ensure that it is safe for rescuers to approach. Leaking
fluids, downed power lines, or injured pedestrians can all pose
risks to crews. Only when the scene is deemed safe, rescuers can
approach. Vehicles often end up in very unstable situations as a
result of a crash. Stabilization is a very important element to
a successful extrication operation. Special struts, wood
blocking, and lifting bags can be used to keep a vehicle from
moving or rocking. This is important to protecting a patient
that could have a spinal cord injury. During this time EMT’s
will make contact with the patient, assessed their injuries and
help determine the safest and fastest way to remove them from
the vehicle.
Many times patients can be removed without
cutting apart the car, but in some instances we must remove
parts of the vehicle to safely extricate the patient. The most
common tool is the Jaws of Life. These are very specialized
hydraulic tools that cut and spread with incredible force.
Common reciprocating saws and hand tools also play a large role
in vehicle extrication.
There is a lot to know and there is even
more to be able to do. The CFD Training Bureau works hard on
providing the best training possible to our members. Vehicles
are brought in from a salvage yard and staged in various crash
scenarios to give rescuers the most realistic training
opportunity possible. Outside instructors and speakers are often
asked to speak to our members to keep them up to speed on the
latest extrication techniques and vehicle technology.
There is a lot of effort put into training
our extrication crews, in order to deliver the best possible
service to the community we serve.
