Dave Dalrymple discusses scene-hazard evaulation and reviews ways of stabilizing a vehicle. Sponsored by Holmatro.
[MUSIC] [MUSIC] Hello fellow rescuers, my name's Dave Dalrymple from Roadway Rescue. We're going to be doing some training clips on vehicle rescue today. But first off, just like every other incident, we want to make sure our scene is safe. So what we're going to show you first is a scene assessment, then we're going to stabilise the vehicle. When we're assessing our scenes, remember, we're looking for the big picture, all the way around. We're also looking in close to the vehicles. We're looking for possible clues for entrapment. We're looking for hazards to us. And we're also looking for potential injury to our patients. So we can come back. Put our plan together. And make things happen. Okay. Our stabilization, we're gonna set it up. We're gonna put four points of stabilization underneath the vehicle. We're gonna put two points in front of the rear tires, and we're gonna put two points behind the front tires. We're gonna use a combination of devices here, we're gonna use a rapid stair, and we're gonna use a step chalk. I just put in a rapid stair and start it as tire deflation. John's gonna come in and put a step chalk in, as as well as a tire deflator to deflate the front tire. Once the tire's deflated the car'll be sitting down on a platform. It'll be solid and ready to work for you too work wise. [SOUND] Okay our three stabilization devices that we used today, the first one you're probably the most familiar with, a step chock. Now the reason why it's called a step chock, obviously because the steps themselves are in a stair fashion to slide underneath the vehicle so we can catch different points of the vehicle to make it solid. Some people can also turn this over and use it as a big wedge. Now that's good, because that'll take up a lot of space in a hurry. Now, one of the other devices we used, we also used a rapid stair. Now a rapid stair, in it's fashion, is a little different. Same type of concept though. Something to put underneath our vehicle for our point of contact, but the difference is [COUGH] instead of a wedge going underneath our step [UNKNOWN] to take up space, this, the wedge, actually travels. and how would we set, how would we set up underneath the vehicle would slide underneath the vehicle, the [UNKNOWN] put their foot up against this. And then they would pull this cord, and this would slide up. As it slides up, you'll see it's also locks into the track each time. As it comes up, it wedges itself between the vehicle on the platform and the ground with the Rapid Stair itself. Our third example is a quick chock. Now, how did a quick chock came about? Well, one of the things that we're finding is step chocks on modern vehicles have a tendency to stick further and further out because the vehicle themselves. Have less and less ground clearance. Now, the problem with that is step chalk, as you all know, will stick further out. It'll be a trip hazard. But also, when you try and do some of your door or side evolutions get hung up on that step chalk when the piece of the vehicle actually comes off. This idea, being a platform and then on top of it. A wedge gets inserted, either a four by six wedge, or a six by six wedge on top of the platform. Takes up a lot of space, quickly, but also facilitates this as an operational, much quicker than a step [UNKNOWN]. Basically you can drop the platforms on the ground. Sliding them underneath the vehicle so they're flush with the side of the vehicle itself, and come back with a wedge and take up the space quickly and make the car nice and stable. And actually have a more solid platform than a step shock because of the width of the platform and the width of the wedge itself. Finishing up our stabilization, remember we want to put four points of stabilization underneath the vehicle. Two points behind the front tires, two points in front of the back tires. Once we got the cribbing in place that takes out our, our suspension, we're gonna deflate the tires. Deflating the tires. Drops the vehicle down onto our platform, making it rock solid for our tool evolutions to work. The one thing you need to remember though, modern cars, vehicles, manufacturers are going towards run flat tires. Run flat tires aren't gonna allow us to deflate tires to bring the vehicle down onto the cribbing. We're gonna have to bring the cribbing the rest of the way up to make that solid platform to work off of. Now after we've stabilized the vehicle one of the important things that we need to do today and this is with every incident involving a motor vehicle is wanna secure the power to vehicle. The first step for that is gonna be shut off the ignition, take the key away from the vehicle and that's important because a lot of vehicles today have proximity ignition or proximity keys. That type of key needs to be out, away from the vehicle itself, in fact the best practice is to put it back in your apparatus. Once we've got the key out of the mix we want to make sure we come in and find the 12 volt battery, disconnect it or cut the battery cables depending on what your department's preference is. Both the negative and the positive terminals. After we've done that, we wanna make sure we get our patient covered up and protected. Cause we're gonna be going on to and removing the glass from the vehicle as needed. [MUSIC]
