RTC Flashcards
What are the stages of the team approach?
Safety and scene assessment Stabilisation and initial access Glass management Space creation Full access Immobilisation and extrication Evaluation
What must be done before any work is carried out?
360 degree survey / scene assessment
During the stabilisation and initial access phase, why is it important to stabilise the vehicle?
Stabilise to help facilitate initial access
Creates a a solid working platform
Prevents further deformation of the car
Stabilisation of the vehicle can be done in three stages, what are they?
Manual stability
Blocks and wedges
Supplementary equipment
Flat tyre blocking is controversial, what are the considerations when using this technique
Rescuers must communicate with police prior to deflating tyres
Once extrication is complete the vehicle will need to be lifted to recover blocks and wedges
The vehicle may be difficult to move after causing delays to reopening the road.
When using wedges on an EV what must be considered?
Double wedge incase of spontaneous movement
Fuses
Keys
Incorrect
During stabilisation what are the priorities for a conscious and unconscious casualty?
Conscious - eliminate vehicle movement and protect against further pelvic / spinal trauma (block & chocks + supplementary equipment)
Unconscious - gain rapid access and ensure casualty has a patent airway) (manual stabilisation to allow rapid access for medic, then continue with chocks & block + supplementary equipment)
What are the three options for glass management?
Controlled removal
Controlled breakage
Leave in position / situ
What are the two types of glass we likely to encounter?
Toughened - usually on every window except windscreen
Laminated - usually on the windscreen
As medic when with the OIC during 360 survey what equipment should you grab?
Soft protection
Airbag block
How many points of stabilisation does a car on wheels need and where are they?
7
Opposing front and rear wheels
Under A & C pillars on both sides
Rear of the car (not bumper)
Space creation can be looked at in two ways. What are they?
Internal - seats, head rests, contents
External - b-pillar, doors, hatch
When must you re-check stabilisation of the vehicle?
When weight is added
When weight is taken away
With large vehicles that may be carrying a load
Where should personnel not actively involved in the incident position themselves?
In the tool staging area so the OIC knows what resources they have
What is the full extended length of the hydraulic ram?
1275mm
What pressure do the holmatro tools
operate at?
720 bars
25 bar return
How long are the holmatro hoses?
10m
When would you use 9 points of stabilisation?
When performing a dash roll, two extra points under the b pillars
What are the 4 types of collisions?
Vehicle hitting a object
Occupant hitting the vehicle structure
Occupants internal organs continue to move causing tearing before impacting the abdominal wall
Unrestrained objects in the vehicle hitting the occupant
Signs of a frontal impact
Front airbag deployment Deformation of the front of the car Deformation of the a pillars Casualty trapped by the dash Bullseye (hair and blood)
Signs of a Side impact
Side curtain deployment B pillar deformation Damage to doors Deformation of roof rail Casualty trapped by b pillar Massive intrusion of the b pillar Massive intrusion of the passenger well
Two types of rollover
Roof retains its structure
Roof loses integrity
Signs of a roll over?
All airbags deployed Possible deformation of ABC pillars Damage on all panels Damage to ground & surrounding environment ROPS
What does tension, flexion & torsion?
Tension - stretched / elongated
Flexion - bent
Torsion - twisted
Contents of the paratech airbag kit?
2 airbags 1 pressure regulator 1 controller 2 in line relief safety valve 3 coloured hoses (10m)
Max lifting for paratech airbag?
300m
Max lifting weight for paratech airbags?
24 tonnes (can stack 2 for same weight) 40 tonnes side by side
Where are the Epidermal injection data sheets?
Trauma pack, HSE, control
How to identify an EV?
Charing port Blue badge Possible green area on license plate General appearance Grills (lack of) Orange cable No sound No exhaust
