Vehicle Rescue Tips (Roof Landing) Roof Rollover Accident & Site Assessment

First, the roof overturned car accident

Vehicle rollover is a relatively common event and often causes problems for rescue workers. It is important that we need to identify two types of rollover accidents.

1. The roof structure of the vehicle that has been turned over remains intact

2. The roof structure of the vehicle that is turned over is incomplete

Due to the fact that the roof reinforcement is now better, the incompleteness of the roof structure in the rollover accident is less common, but it can still happen sometimes.

Rescue workers are less trained in this area (especially in the event of a loss of integrity of the roof structure during a roll-over accident). Therefore, rescue workers are not familiar with the rescue programs that can be used.

In this case, the vehicle means :

1 , it is difficult to identify the identity of the injured

2 , the stability is complex

3 , Because the support rod needs to support more important positions, the opening of the rear hatch will be more violent

4 , not much room to make room

5. There aren't many options for making a full open rescue channel

Remember that the options you choose and the space you make up depends on the time available. The physical condition of the injured determines the length of time.

The following points deal with the situation of roof overturning accidents on the roof:

1. Vehicles on the roof may be flipped many times, so consider the dynamics of the vehicle

2. The injured person may be strapped to the seat so that the entire person is in an inverted state.

3 , the force of turning the vehicle may throw out people in the car, so consider the dynamic factors

! Remember - the vehicle on the roof is still a car, so the structure and condition of the vehicle is the same. The location of the vehicle is complex and the plan is limited, but prior training and planning should allow the rescue personnel to have enough confidence to deal with such accidents, just as it is to deal with a car-overground accident.

Second, security and on-site assessment

Upon arrival at the scene of the accident, the commander must complete a full investigation before proceeding. If there are still undetermined hazards in the investigation, do not allow rescue personnel to enter the danger zone without understanding the danger.

Omni-directional survey - need to determine the situation

In addition to the above risk factors, the 360- degree survey must also include the identification of risk factors under the vehicle.

Additional considerations for vehicle landing on the ground

Due to the special nature of such accidents, please pay special attention to:

1 , instability

2. If there is a 12- volt battery under the engine valve cover , it cannot be removed.

3, the exposed catalytic converter and the exhaust system (at a temperature of about 700-900 degrees C)

4. Exposed or damaged high voltage cables or batteries on hybrid or electric vehicles

5 , fuel (or other) leakage risk

Once the investigation is completed, the on-site commander must determine the priority level to ensure that the dangerous situation is addressed, and also adopt control measures to reduce the risk.

When the initial investigation and priority level were determined, the role of the field commander was to maintain the safety of the entire rescue scene. Only by standing in a good position can you view the entire county at any time.

! Remember - Rescue can only be done after completing a 360- degree survey and having identified and communicated all risk factors. As the dynamic and safety-related issues at the rescue site are constantly changing, it is necessary to continue the assessment.
