In emergency or disaster rescue, time is life. Rescue hydraulic tools play a vital role in emergency rescue scenarios such as car accidents, earthquake rescue, and building collapse due to their powerful cutting, expansion and support capabilities. Mastering the correct use method can greatly improve rescue efficiency, reduce rescue time, and thus save more lives. This article will introduce how to use rescue hydraulic tools correctly and safely for quick rescue and escape.
Hydraulic expander
Mainly used to expand deformed car doors, carriages, metal frames, etc., to provide escape routes for trapped people.
It can also be used to remove obstacles and increase rescue space.
Hydraulic shears
Used to cut metal structures such as car doors, window frames, guardrails, steel bars, etc., to help rescuers quickly break through obstacles.
The blade is sharp and suitable for cutting high-strength materials.
Hydraulic jack
Mainly used to open narrow spaces, such as flattened carriages, collapsed building gaps, etc., to create living space or rescue channels.
Suitable for supporting unstable building structures to prevent secondary collapse.
Hydraulic combination tools
It has both shearing and expansion functions and is suitable for complex rescue scenarios, such as rapid demolition at car accident sites.
Hydraulic demolition machine
It is used to demolish solid concrete, metal doors and windows, etc., suitable for building rescue and earthquake rescue.
1. Assess the site and formulate a rescue plan
Ensure safety: Before entering the rescue area, confirm whether there are dangers such as secondary collapse, gas leakage, and short circuit in the surrounding environment.
Determine the rescue point: According to the situation on the scene, decide whether to shear, expand or support, and choose the appropriate hydraulic tool.
Comfort the trapped: Inform the trapped people of the rescue process, reduce panic, and avoid secondary injuries caused by struggling.
2. Prepare tools and deploy quickly
Check equipment: Make sure that the hydraulic tools are intact, the hydraulic pump is operating normally, and the connecting pipes are leak-free.
Connect the hydraulic system: Connect the hydraulic shears, expanders or jacks to the hydraulic pump and perform a no-load test.
Choose a stable operating position: Ensure that the force point of the rescue tool is firm and will not collapse or slide due to operating errors.
3. Use tools correctly for efficient rescue
(1) Expand the rescue channel (applicable to car accidents and collapse rescue)
Position the expander: Insert the two arms of the expander into the gap of the deformed car door or metal frame.
Slowly expand: Gradually increase the hydraulic pressure to expand the trapped space to ensure that no secondary injury is caused to the victim.
Fix the channel: After expansion is in place, you can use a top support tool or a wooden block to fix the channel to prevent collapse.
(2) Cut obstacles (applicable to steel bars and metal demolition)
Choose the correct cutting position: Avoid cutting high-strength alloy parts, such as the A-pillar of the car, to prevent damage to the blade or rescue failure.
Cut in place at one time: Make sure that the scissors blade is close to the metal part and cut it at one time to reduce unnecessary repeated operations.
Keep stable: During the cutting process, ensure that the tool is stable with the ground or support surface to prevent reaction force from causing operating errors.
(3) Hydraulic jacking and support (applicable to building rescue and escape from narrow space)
Choose a suitable support point: place one end of the jack on a solid support surface, such as a concrete wall or metal structure.
Slowly pressurize: gradually push the jack to expand the living space and ensure that there will be no secondary collapse due to excessive pressure.
Fixed support: after expanding to a suitable space, wooden boards or other structures can be used to reinforce the support to prevent the structure from shrinking.
Avoid accidental injury to trapped persons
When operating in a narrow space, ensure that the rescue channel is unobstructed to avoid tools hindering the evacuation of personnel.
Maintain stable operation
When applying force with hydraulic tools, rescuers should stand firmly to avoid imbalance due to the reaction force of the tools.
Try to use both hands to operate to ensure that the tools do not slip or lose control.
Maintain equipment regularly
After each rescue, clean the tools and check whether the hydraulic pipes, blades, and pump bodies are damaged.
Replace the hydraulic oil regularly to keep the equipment in optimal working condition.
