Vehicle rescue skills (on-site treatment) Disappearance of the roof caused by underwater or near-water rescue & reversal accidents

A. Underwater or near water rescue

Rescuers must work hard to prepare for rescue in all situations and predict the type of accidents that will be performed next. Underwater vehicle rescue has its own set of principles and considers different factors. However, when the situation on the site requires rescue workers to perform rescue operations, is safety and operability feasible?

Without adequate preparation in advance, rescue workers may be negligent in such accidents. "Cross" training or multi-disciplinary training (involving vehicle rescue techniques and underwater rescue) must be part of practical training.

Security entrance

Due to the characteristics of such accidents, the arrival plan for a standard accident site will not be feasible. If a working system is not established, it is impossible to reach the accident site and rescue the injured. The system includes rescue personnel wearing personal protective equipment ( PPE ) that can be used for underwater rescue .

More difficult to carry out the operation is to determine the vehicle's fuel type and isolate the battery to airbags may cause the danger of elimination, refers to the hybrid model. Since the vehicle is located in water, it is also difficult to carry out the stabilization of the vehicle. This will reduce on-site safety and affect the physical condition of the injured. To make room, half of the hydraulic rescue equipment needs to be immersed in water. Are these tools safe and effective in this situation? Not all tools have a design for this purpose, so it is important to understand the limitations of the tool.

Once the entrance is completed, the condition of the injured person needs to be immediately evaluated using dynamics and injury principles and the first priority and second priority investigations should be conducted. But at this time the wounded are in cold and even dangerous waters. This situation increases life-threatening risk factors and therefore requires rapid rescue.

If the accident is foreseeable, it should be prepared in advance as follows: conduct theoretical research studies, formulate practical plans while observing the local standard operating procedures (both principles apply) and select the most appropriate rescue tools so that rescue workers can The final rescue is ready.

Second, the collapse of the roof caused by the collapse of the accident

Due to the reinforcement of the roof, the structural strength of the roof of the roof may be reduced in such accidents. However, this situation does happen, so we need to be prepared.

The initial problems faced are:

1 Difficult to make initial entrance

2 difficult to determine the location of the injured and contact the injured

3 It is difficult to create the ultimate rescue space

For vehicles facing any direction, in general, the team work method is easier for making entrances and determining the condition of the injured.

Stability and initial entry

The stability of the vehicle in this case is more complicated. The gap between the road and the structural components of the vehicle must first be determined. Other extra equipment may be required at this time, such as vehicle stability struts, but the most effective method is to use pads and wedges.

Releasing space in such accidents may only be surrounded by the need to use an emergency support system as an initial fix, as the system can be lifted (if needed) during the rescue process.

Our plan selection will be subject to the method of space evacuation - reversing the limitations of the entry of the vehicle into the car as described in the section of the vehicle.

Glass Management

Due to the damage of the vehicle and its location, the glass treatment will be limited to the removal of damaged glass in the occupied area.

Space vacated method

In order to make room for such accidents, rescue workers need to use the technique described in the “turning over” part lock.

The deformation of the roof means that once the initial entrance is made, rescue workers cannot easily make more room in the car. The use of rams and hydraulic support (with lifting function) is the most efficient method. Once the mandrel or support device is ready, safety cuts can be made in the B and C posts. The jack or support device can then be extended to create more space. See "Clamshell Technology" below.

Shell Technology

This method is intended to increase the working space inside the inverted vehicle, in which case the structural strength of the vehicle is weak. In order to achieve the best results, the shells on both sides of the vehicle body should be peeled off as described above.
