Steve White demonstrates basic extrication techniques for cabs of large-sized trucks like big rigs.
[BLANK_AUDIO] [SOUND] [MUSIC] [MUSIC] Welcome to Fire Engineering's training minutes. I'm Steve White, Battalion Chief, Fishers Fire department. In this segment, we're gonna discuss basic extrication through the cab of the truck. Again, building on our principles that you can't take a small vehicle approach. To a big truck rescue. A simple task as moving the door can be very challenging. When we look at certain items such as the mirror, the breather, the grab handle, and the stack. Even looking at the door on size up with the latches, we cannot be sucked into thinking that that's where the Nader is. In this evolution, we're going to attack the door from the Nader side. By opening the door, you can see that the Nader actually latches at the center of the door frame. So that's where our tool work needs to begin when we're doing, doing this tactic. [SOUND] As in any other extra case in evolution, the vehicle is stabilized for four points of contact. We have box curbing. On four points at the front and the back. We're gonna start with gaining access through glass removal. Remember, when we have a victim, it's important to make sure that they're covered with a rescue blanket. Typically our side glass is tempered and can be removed with your standard center punch. When we remove the windshield, it is also a standard laminate. Two-piece laminant. Usually, it's kept in place, by a two-part gasket, which we'll remove, to get the windshield out. [pause] There are several different ways that we can remove the laminated glass, through the gasket. One is pulling the center bead. And making that gasket loose. Ultimately, the goal is we're trying to take it out without having to use a glass tool. Which reduces the amount of small, pieces and particles of glass, that are associated with using a glass tool. As you can see we're working outside the cabin. Having the victim covered, removing of the windshield is relatively simple. In this step, working as a team, we're going to remove the stack. [SOUND]. It's important to remember, we must steady the object before we cut it. (Loud sawing in background.) [SOUND] Dropping the object down under control and carrying it away is a good safe approach. [BLANK_AUDIO] [SOUND] [SOUND] [NOISE] [NOISE] [NOISE]. [NOISE] It's always important to remember that we should never place ourselves between the tool and the vehicle. [SOUND] Now we have all of the obstacles removed from our means of attacking the door with a nader pin. One thing I want to point out in the evolution was that we used a combination of tools, power hydraulics. Sawzalls and chisels which could all be used on these various components. The next step is to attack the ___ in the door and get it removed. One thing that we want to point out is you can see the use of the ladder is pretty critical for rescuer safety. As an alternative you could bring in a flatbed wrecker, which provides a, a base, of stability, for the rescuers when operating their tools. Otherwise we'll be working above our waist, which is where our common point is, for attacking cars, but now we're gonna be a bit higher. We can also do that with an A frame ladder. But by using a flatbed wrecker, we provide a suitable base for our personnel, our equipment, and even to the final step when you remove the victim. Because just imagine trying to get a victim out of that seat with a great deal of height to overcome. The flatbed wrecker, when special called for. Can address a lot of these challenges for rescuers in big truck extrication. [NOISE] To gain access to the niter we're gonna try to gain a purchase point so that we can fit the tips of the spreader between the door and the B post. [SOUND] Gaining access to [UNKNOWN] can be very challenging. So starting at the top of the door frame and tunneling your way down is usually your best approach. Once the nader is exposed, we can either continue attempting to spread were we can gain enough room to get the cutters in to cut the door from the nader. [NOISE] Now come down. [NOISE] There you go. [NOISE]. [xx] [SOUND]. Now that the evolution is done you can see how we removed the door. Attacking from ____ pin really is very challenging. A good alternative option would be to go from the hinge side. So rescue being the science of alternatives, you've gotta be able to take from this evolution what the actual impact over the accident will give you. The use of the flatbed record, again, proved its worth in providing a safe base for rescuers to keep their tools at their waist, not bringing it above their waist. Having a good platform for balance and control. And, had we had a victim. To be able to package and remove onto the platform, to the edge, to awaiting personnel, to take the transport to the hospital. That concludes this segment for Training Minutes.
