Extrication 1 Flashcards
As soon as reasonably possible the OIC on scene should devise a plan of extrication that consists of what?
Rapid and immediate
The decision of which stability to use initially is based on what?
Initial level of response and safety
There are generally two types of cut. What are they?
Surrounding cut - The blades fully surround the material to be cut.
Penetrating cut - The blades penetrate the material to be cut.
What % of c-spine injuries result from RTC’s?
50%
Ultra high strength steel has become prevalent in vehicles over recent years. What is it otherwise known as?
Boron
Where possible cut at 45%, this is more efficient when cutting a b-pillar for example, this gives the operator more space in which to work. True or false?
False. Cut at 90 degrees
An effective OIC should foresee problems that may delay extrication and amend the plan as necessary, ensuring any changes are fully communicated. This is done by the process of what?
Anticipate - evaluate - update
What are the primary glass management options
Leave in situ
Controlled breaking
Controlled removal
The most common application for hydraulic rams are what?
Dash lift / roll
Cross ramming
What are tension, torsion and flexion?
Tension - Metal that has been stretched or elongated
Torsion - Metal that has been twisted
Flexion - Metal that has been bent
Establishing a working area around the vehicle involves 2 cordons, what are they?
Inner and outer
What are the dynamic hazards present in an RTC?
Weather conditions
Vehicle stability
Broken glass and sharps
What hazards contribute to the hazardous environment of an RTC?
Extreme weather
Physical hazards (uneven ground / live road furniture)
What must be carried out prior to any extrication work, in order to ensure all hazards are identified and communicated?
360 degree survey
Using a valve key is safe and effective for flat tyre blocking. Before deflating tyres what must you consider?
Rescuers MUST communicate with police prior to deflating tires
Flat tire blocking is not as effective when the vehicle is on sloping or uneven ground
Once the extrication is complete, the car will need to be lifted in order to recover blocks and wedges
A vehicle with flat tires is difficult to move and this will delay reopening of the road (backing up traffic and potentially causing further collisions)
Always deflate tires via the valve. NEVER PUNCTURE A TIRE WITH A KNIFE OR OTHER SHARP INSTRUMENT as this will make it harder to relocate the vehicle (if required), and it may also hinder subsequent police investigations.
