1. The core significance of vehicle rescue
Vehicle rescue is not only a technical task, but also a key action to protect lives, reduce secondary injuries, and control the impact of accidents. According to statistics, about 1/4 of the trapped people may suffer secondary injuries due to improper operation during the rescue process. Therefore, professional and rapid rescue directly determines the recovery cycle and quality of life of the wounded, and we are not only rescuing the wounded, but also protecting their future life ability.
2. Main accident types and injury characteristics
Common accidents
. Front impact, side impact, rear-end collision, rollover, rollover, overlap, stacking, cliff fall, suspension.
Typical injuries
. Head trauma (glass), neck spine injury, chest squeeze (steering wheel), pelvic and lower extremity fractures.
Rescue focus
. Avoid aggravating cervical spine injuries, internal bleeding, and sharp object punctures during rescue.
3. Introduction to common rescue equipment
equipment | Main uses: |
Hydraulic shears | Shearing A/B/C columns, manufacturing life-saving entrances, opening the "third door" |
Hydraulic expander | Expand the doors, raise the dashboard, and tear apart the body structure |
Hydraulic toppers | Move the instrument panel, top support the body |
Universal shear | Cut steering wheel, pedals, seat |
Pneumatic/electric demolition tools | Assisted demolition, suitable for scenarios without hydraulic sources |
Heavy-duty support kit | Secure the vehicle and prevent movement |
Ball lifting air cushion | Jack up the car body to create space |
Sharp edges/airbag protective cover | Covers sharp areas to prevent accidental ejection of the airbag |
Glass breaker | Quickly clear the window glass |
Spinal plate/KED | Fix the spine of the wounded to avoid aggravating injuries during transportation |
4. Basic rescue process (5 steps)
On-site assessment and control
. Setting up a warning zone (5 meters work circle, 10 meters preparation circle)
. Carry out hazard identification: environment, vehicle, dynamic, and casualty hazards
. When the vehicle is powered off, check the oil circuit, airbags, and battery (especially for electric vehicles)
. The vehicle is stable
. Use of spacers, support bars, heavy kits to secure vehicle stance (rollover, pushover, etc.)
. Immobilization is the basis of rescue, preventing movement from causing secondary injuries
Create a rescue space
. Technicians demolished, safety officers monitored, and medical personnel entered the car to comfort and monitor vital signs
. Common operations: squeezing fenders, expanding doors, pushing off/raising instrument panels, cutting roofs
Fixation and initial medical treatment of the wounded
. Stabilize the cervical spine with a neck brace/KED (30–40% stability only, with a head support at all times)
. Cover the wounded, isolate sharp objects, and pay attention to heat preservation/cooling
Safe transfer
. Slide out to reduce the frequency of spinal movement
. Continuous monitoring until handover to the medical team
5. Safety precautions
. Personal protection: Wear PPE such as helmets, goggles, gloves, and rescue clothing throughout the entire process
. Tool safety: check the hydraulic pipe joints to prevent oil pipe burst and spray; Select a safe station during operation
. Casualty protection: always cover the wounded with a protective cover, and the tool is isolated from the human body by a hard plate
. Teamwork: Clarify the roles of command, safety, medical, operation, and driver, and cooperate with a minimum action team of 6 people
Rescue is not only the application of technology, but also the respect and protection of life.
Every safe and professional rescue may put a life on its feet again.
Please always remember: fix first, then dismantle; protect the wounded and protect themselves; Team collaboration, safety first.
Salute to every rescuer - you are the "life engineers" at the scene of the disaster.
