Vehicle extrication tools and stabilization equipment: how crews free trapped people
What each rescue tool does, why steadying comes first and what to ask locally
Safety Behind the Wheel Foundation built this guide from Insurance Institute for Highway Safety (IIHS) data, Occupational Safety and Health Administration (OSHA) rules, federal electric vehicle safety rules, expert consensus statements and published rescue research from the United States, the United Kingdom and Norway. Every source is listed at the end.
What this equipment does and who uses it
Extrication is the process of removing injured or possibly injured people from a vehicle after a collision [1]. Stabilization comes first. Crews brace the wreck so it cannot roll, slide or tip while they work. Think of the two as one job: make the vehicle safe to work on, then make a path out for the patient.
The equipment falls into three groups:
- Stabilization gear: blocks, wedges, struts, straps and chains.
- Opening tools: hydraulic spreaders, cutters and rams, plus hand tools and saws.
- Lifting and pulling gear: lifting bags, jacks and winches.
Fire departments carry most of it, and EMS crews work beside them. Towing and recovery operators use stabilization and pulling gear to secure and move wrecks. Road agency incident teams and trained workplace responders, such as an industrial plant’s fire brigade, may carry parts of the kit.
Typical scenes include a car on its roof, a vehicle down an embankment, a car under a truck trailer, and a person pinned by a crushed door. This gear is a readiness tool. It sits idle for weeks, then must work on someone’s worst day.
It is professional equipment that takes training. This article explains it so you can understand a scene and ask good questions. It is not a how to guide. Our post crash care guide covers your first minutes. Companion articles cover scene lighting, cones, barriers and spill cleanup.
Why speed and care both matter
In 2024, motor vehicle collisions killed 39,254 people in the United States [4]. Experts estimate that up to 40% of injured patients may stay trapped in their vehicles after a collision [1].
An English trauma registry covering 2012 to 2018 listed 6,983 trapped patients among 63,625 injured patients [2]. Trapped patients died more often (8.9% versus 5.0%) and had higher injury severity scores [2].
Time is part of the story. A study of fire service rescues in the West Midlands region of the United Kingdom asked what slowed crews down [5]. A physical obstruction added about 10 minutes. Each medically trapped patient, someone kept in place because of injury concerns, added about 10 [5, 6]. Quick access cut about 7 minutes, and a car resting on its roof cut about 12 [5]. These are British figures. They show patterns, not U.S. standards. They also show why crews study the whole scene before they pick up a tool.
Experts are rethinking the old goal of keeping a patient perfectly still at any cost. In the English registry, spinal cord injury appeared in 0.71% of extricated patients [2]. A 2025 consensus of 43 experts backed self extrication, where a patient climbs out with guidance, as the preferred first approach [1].
Place matters too. In 2024, 41% of crash deaths in the United States happened in rural areas, and the rural death rate was 1.56 per 100 million miles traveled, against 1.01 in urban areas [7]. Every community needs a clear answer to one question: who will free a trapped person here, and how fast?
Stabilization comes first
A wrecked vehicle may rest on its side or roof, on soft ground, or on top of another vehicle. Spreaders push, cutters shear and rams shove. Those forces can shift a wreck that looks still. So crews make it steady before they open it.
Comparison compiled by Safety Behind the Wheel Foundation
Stabilization gear and common mistakes
| Gear | What it does | Common mistake |
|---|---|---|
| Cribbing (stacked wood or plastic blocks) | Builds a solid base under or beside the vehicle | Uneven stacks, cracked blocks, or a base on soft ground |
| Step chocks and wedges | Fill gaps and stop small movements | Using too few, or leaving gaps |
| Wheel chocks | Stop the vehicle from rolling | Trusting the vehicle’s own brakes instead |
| Adjustable struts | Brace a vehicle on its side or roof | Setting them on weak ground or weak body parts |
| Straps, chains and winches | Tie down, hold or pull a vehicle | Anchoring to parts that can tear or bend |
| Lifting bags and jacks | Raise or shift heavy loads | Lifting without a second support under the load |
Stabilization also protects people outside the car. A review of 106 OSHA cases of tow truck operators killed or badly hurt found that about nine in ten fit two patterns [8]. In one, the operator was struck by traffic, rolling vehicles or equipment. In the other, the operator was caught in or between vehicles, often pinned [8]. The authors urged training on wheel chocking and braking procedures [8]. Safety Behind the Wheel Foundation supports that training for every crew that works around wrecked vehicles.
If you are the patient, the sound of blocks being set can feel like delay. It is protection. Tell crews at once if you feel the vehicle move.
The tools that open the way
Many rescues start with simple steps, such as opening a door, moving a seat or guiding a person out. Expert panels favor the simplest, safest and quickest plan [9]. When that is not enough, crews use power tools:
- Spreaders push or pull parts apart, such as a crushed door.
- Cutters shear metal, such as roof posts and door frames.
- Rams push a crushed dashboard or door away from the patient.
- Hand tools, saws and glass tools handle small jobs and fine work.
Many of these tools run on hydraulic pressure, and some on batteries. Researchers say patients who must be freed from wreckage need “cutting and spreading tools” [6]. Rescue gear has become faster and more powerful since the 1950s [1].
In a study with six healthy volunteers, researchers compared roof removal, a B post rip, rapid side door removal and self exit [6]. The B post is the center pillar between the front and rear doors. Roof removal and the B post rip involve cutting the vehicle, and rapid side door removal uses no tools [6]. All three caused similar spine movement in prepared cars, and self exit caused the least [6]. The volunteers were not truly trapped, so the study cannot predict results for injured people [6].
Winch and chain methods exist too. In Norway, a rapid method uses two vehicles, hydraulic tools and chains. One vehicle holds the wreck in place while the other pulls it apart [10]. Of 219 fire departments that answered a survey, 95% had adopted it for passenger cars [10]. The authors work for the group that teaches the method. They said simpler, cheaper tools need safety study first [10].
Modern vehicles change the plan
Modern vehicle design changes how crews get you out. Expert panels say vehicle construction and new technology, such as electric power, should be weighed in every extrication decision [9].
Electric vehicles show why. A federal standard aims to cut deaths and injuries after a collision from battery fluid leaks, battery parts moving into the cabin, shock, fire, explosions and released gases [11]. It requires a warning symbol on or near energy storage devices [11]. Compliance is due September 1, 2027 for vehicles up to about 10,000 pounds, and a year later for heavier ones [11].
Crews also need a map. Federal rules describe a rescue sheet as a quick summary of how a vehicle is built, made for crews at a crash scene and drawn from a longer emergency response guide [12]. The longer guide covers topics such as fires, vehicles under water, fluid leaks, towing and storage [12]. The federal rule on these documents covers electric powered vehicles [12].
Training is the weak link. A national survey of more than 1,000 responders in all 50 states and Washington, D.C., found that over 40% had never had electric vehicle safety training [3]. Towing and recovery responders knew less about electric vehicle fire tactics than firefighters did [3].
Three questions matter at any scene. What is this vehicle? What powers it? Where are the parts we must not cut or lift? You can help answer them. Tell crews what powers your vehicle and what has been added, such as a wheelchair lift, hand controls or extra batteries. Our guide to what to do with an electric vehicle after a serious crash covers the aftermath.
Who decides what to buy, and how to choose
Public fire and EMS chiefs and their governing boards choose gear for their departments. Employers choose for workplace teams. Towing owners and road agencies choose for their own crews. Typical sources are professional emergency equipment suppliers and authorized dealers. Good ones offer demonstrations, training, service and parts. Consumer marketplaces may offer none of these.
A buyer who wants to choose well would ask:
- Which vehicles do we actually respond to? Think cars, electric vehicles, heavy trucks, buses and farm equipment.
- What test does the maker cite, and who ran it?
- Will our neighbors’ tools connect to ours and share batteries when we work together?
- Who trains our crews, and how often do they refresh?
- Who services the tools, how fast, and is a loaner available?
- What will the tools cost to maintain over their full life?
Standards give a floor. When an employer sets up a fire brigade, such as at an industrial plant, OSHA requires a written policy, training that fits the duties, and training at least once a year [13]. That rule does not replace the maker’s manual or technical rescue training. Public departments should be able to say which training standards they follow.
Road agency crews often arrive early to protect the scene. OSHA lists struck by and caught between among the common hazards in highway work zones [14]. Only authorized agencies select and place public traffic control devices.
Limits and common mistakes
Even good equipment fails when people make these errors:
- Rushing or skipping stabilization. A shifting vehicle can hurt the patient and the crew.
- Reaching for power tools first. Researchers note that tools can cause costly vehicle damage, demand people and equipment, tire the crew, and put patients and rescuers at risk [6].
- Skipping training on new vehicle types. An electric vehicle, a bus and a pickup need different plans, and the survey gaps above show why [3].
- Ignoring noise. In a study of 56 firefighters in extrication and collapse training, noise above 90 decibels in the prior 30 minutes went with much higher odds of an injury or near miss [15]. Hearing protection that allows radio talk belongs in the kit.
- Forgetting the person inside. Experts say extrication is a medical intervention. They also agreed that, when practical, a trained person should stay close to the patient to reassure them and explain what is happening [9].
Being trapped can leave a mark. Experts agree it brings strong distress and raises the risk of longer term harm [9]. Our post crash guide lists ways to find support.
The evidence has limits too. Most of the extrication research above comes from the United Kingdom and Norway, and some is expert opinion rather than outcome data [1, 9]. U.S. departments set their own protocols, so ask yours how it applies this evidence.
Keeping equipment ready
Rescue tools must work on the first try. For workplace fire brigades, OSHA requires that fire fighting equipment be maintained and inspected at least annually, and that damaged equipment be removed from service [13]. Good practice for rescue tools follows the same idea, with the maker’s manual setting the details.
A sound upkeep routine looks like this:
- Build the inspection schedule from the maker’s manual, and write it down.
- After every use, clean each tool. Check hoses, couplers, blades and arms for damage and leaks.
- Check battery charge and fluid levels as the manual directs.
- Inspect cribbing for cracks, soaked in oil and rot. Check straps and chains for cuts and fraying. Retire anything damaged.
- Test run tools on a set schedule, not only on calls.
- Log each check and repair, and tag broken tools out of service.
- Train on the same tools with the same partners, and include newer vehicles.
What you can do
When you drive past a scene
Move over and slow down. Crews work close to traffic. Our work zone and move over guide explains how, and the move over laws by state page shows your state’s rule. Do not stop to film. Never try to free a trapped person yourself unless staying put is more dangerous, such as with fire.
When you are in or near a collision
Answer crew questions about pain as clearly as you can. Tell them what powers your vehicle. Let them lead. Rescue can be loud and close, so ask a crew member to explain what is happening.
When you want answers locally
Raise these questions at a public meeting of your fire district, town or county board, or write to your fire chief or county emergency manager.
If you run a small business
A small employer rarely needs its own extrication team. Most call 911. If you set up an in house fire brigade, OSHA’s rule expects a written policy and training at least once a year [13]. Talk with your fire department and a safety professional before you buy rescue equipment.
Frequently asked questions
Can I buy extrication tools for my own use or my neighborhood?
It is not a good idea. These tools take training, and researchers say they can put patients and rescuers at risk [6]. A better plan is to learn first aid and CPR, know how to give your location to 911, and support your local department’s training.
Why do crews sometimes ask me to climb out instead of cutting the car apart?
Experts now favor self extrication as a first approach when it is suitable [1]. In healthy volunteers, it caused less spine movement than the other methods tested [6]. If they ask you to move, they will guide you. If they ask you to stay put, stay put.
Why does it take so long to get someone out?
Crews must steady the vehicle, make the scene safe and plan their cuts. Obstructions and a trapped patient’s condition can add many minutes [5]. Crews are working as fast as safety allows.
Does every fire department have the same equipment and training?
No. Departments choose their own gear and training. A national survey found large gaps in electric vehicle training among responders [3]. Ask your department what it has and how often crews train.
What should I tell responders about my vehicle?
Tell them what powers it, such as gasoline, diesel, hybrid or electric. Mention added equipment, such as a lift or hand controls. Crews may look up a rescue sheet for your model [12]. Do not assume your car has one, since the federal rule on these documents covers electric powered vehicles [12].
The bottom line
Recommendation from Safety Behind the Wheel Foundation
Safety Behind the Wheel Foundation encourages drivers to move over for rescue crews, tell them what powers the vehicle and ask local departments how ready they are. Extrication and stabilization gear exists to give trapped people a fast, careful way out. Crews steady the vehicle first, then open it with the least force that works. Today’s vehicles make training and vehicle information as important as the tools.
You should not do this work yourself. You can move over, tell crews what they need to know, and ask your local department and employer how ready they are.
