I have been evaluating extrication techniques for the last several months where I utilize two tools to simultaneously displace the desired portion of the vehicle. The example for this post will be a dash displacement so we will begin the discussion with the side of the vehicle already being removed.
Step One: Skin the fender and make full relief cuts on the structural fender rail between the suspension hub and the firewall. Then make a full relief cut on the A pillar between the rocker panel and the dash assembly. These two FULL relief cuts take all of the resistance out of the dash assembly and allow lifting and rolling with significantly faster results.
Step Two: Place a hydraulic ram into a roll position and begin the dash roll. The dash will move quickly and with little resistance because of the relief cuts. Have an additional rescuer place the spreader right at the A pillar relief cut and be ready to insert the tool into the cut as soon as the ram opens the cut up.
Step Three: Chase the ram with the spreader. This does two things. It captures the progress of the roll and it prepares the spreader to immediately take over and lift the dash as soon as the ram max’s out or
Step Four: Once the spreader takes over, the ram can be relocated in a more suitable placement for victim removal because the gap between the rocker and the dash assembly is now much larger. This allows the ram rescuer to place the ram in a more vertical application much closer to the A pillar and dash assembly. The ram can now back up the spreader and chase and immediately take over from the spreader when it max’s out or stops being effective. It is rare that this much dash displacement is required, but this technique has been proving itself to be a safer displacement with tremendous movement capacity.

Snowblower Rescue, Hand in the Machine
Believe it or not…. every year, snowblowers cause more than 500 amputations and over 5000 emergency room visits.
Hand in the Machine
Winter has made an appearance in the northern half of the United States. Some areas have even had enough snow to use a snowblower to clear off sidewalks and driveways. Unfortunately, the US Consumer Products Safety Commission (USCPSC) reports that – each year – snow blower operators suffer more than 500 amputations and over 5000 emergency room visits. The vast majority of these injuries occur while trying to clear snow and ice jams from the collection auger or discharge chute.
First off, the snowblower’s engine will need to be shutoff if it is still running. After that, if the unit has a key it needs to be removed and the spark plug as well. This will release the compression in the cylinder. During your initial scene size-up, you need to determine what type of snowblower your victim was using. The two commonly used are a single-stage snow blower, and a two-stage snow thrower. There’s a three-stage blower which is basically a turbo-charged two-stage.
On a single-stage snow blower, an auger (the blades you see in front of the blower) directs the snow straight throw a discharge chute. The auger makes contact with the surface you are clearing so it should only be used on a paved surface. On a two-stage snow thrower the auger collects the snow and a fan then discharges the snow through a chute which throws the snow faster and farther away. The auger on a two-stage thrower does not contact the surface so it can be used over gravel or dirt.
Two stage snowblowers use a gearbox to drive the auger from a shaft on the impeller. Two stage also have a self-propelled transmission with forward and reverse speeds that propel the unit in order to assist the user. Different than a single-stage, there are two distinct stages of snow removal, thus the dual-stage name. In the first stage, the auger collects the snow and transfers it to the center of the machine and back into the impeller, which then throws it up and out of the chute. The auger and impeller, combined with the power of the engine, remove the snow faster by chewing up snow and ice, and then throwing it through the chute.
Conduction is the process by which we lose heat through direct contact between objects. This can occur when sitting on a cold or snow-covered stump or rock. This can also occur when wet clothes come in contact with your body, by touching cold objects with bare hands, or kneeling on snow. This is another reason why you must insulate the victim from the ground.
Electric/Battery Powered Snowblowers
One of the simplest ways to find a free training prop is to keep your eye out on trash days. Snowblowers with a blown engine or locked up auger are commonly found at the crib by homeowners who throw out their out ones. Secondly, many city DPW yards have scrap metal drop off areas, always check there. Third, ask your local outdoor power equipment store or service center. Many of the chainsaws we buy are from these stores so you may even have a relationship with them. Finally, check craigslist. You may have to pay a few bucks but the site is littered with snowblowers, and everything else.

Man vs. Machine Rescue Awareness
Machine rescue runs have new boundaries and every firefighter needs to understand many different techniques.
Man vs. Machine Rescue
Man vs machine can happen in any city across the world and is not limited to large cities or industrial centers. Don’t get complacent and assume that it will never happen while you are on-duty. Consider a teenager stuck in a full bucket toddler swing seat. Do you know the steps to take get that patient out of the swing? How about a person that has their leg stuck in a PVC drainage pipe in a yard during the winter in below freezing weather? These are two of the incidents I personally ran on and several posts on Paul Hasenmeier’s website provided me with enough information in the full bucket swing ran.
However, I did learn several things during my incident.
- Eliminate gravity from the equation. Bring the stretcher over patient can sit on it while you cut the chains.
- We tried cutting the seat with bolt cutters, cable cutters, and wire cutters unsuccessfully.
- Plan D, we moved the patient to the Rescue truck and used hydraulic cutters. Not the best option, but it worked.
- My department used the full bucket swing to find a handheld ratcheting cutter that cut thru it. It’s now on the rescue.
