[BLANK_AUDIO] [MUSIC] [MUSIC] Welcome to Training Minutes. My name is Steve White, and I'm a Batallion Chief with the Fishers Fire Department. In this segment, we're going to perform a Dash Roll. A Dash Roll is done when the dash of the truck has come down, trapping the driver or passengers at the legs. To do this, this tactic is most effective because we're operating off a full frame vehicle. Using cutters and rams, we're going to take a section of the upper A post out, make a relief cut in the lower A post, then place a ram to pivot the dash up off the lower extremities of the victim. The same steps and actions that are occurring on the driver's side must also occur on the passenger's side. [NOISE] It's important to get a very deep relief cut on the bottom a-post. This may take more than one cut. A chisel may also be used to expand the relief cut. [SOUND]. [BLANK_AUDIO] Now we wanna take a section of the upper A post. Out of the way, so that when we roll the dash, the upper aid post will clear the roof. It's important to note here that you must be able to form size up, make sure that there is no significant roof damage that will cause the roof to come down on the patient. [INAUDIBLE] [SOUND] Now that the upper and lower a post are cut. We are going to use a ramming action. Again this is gonna be on both sides of the dash. As you can see, rolling the dash was able to gain a great deal of space. When we're doing this operation it's critical to monitor the rams. The rams are gonna be expanding our opening here at the lower post pushing the dash up and also bring the column with it. A lot of times you'll also see movement of the petal, because sometimes we can have an entrapment. With the victims foot between petal and the firewall. Another key point to point out, is that the back of the ram, most rescuers keep an eye on the front of the ram and watch the dash move and see if we're getting enough space and that's important. But we always have to monitor the back of the ram to ensure that it does not kick out during the operation. L brackets, or ram jammers, can also be used. To distribute our push point or to gain space based on the size or length of ram that you have in your cache. That concludes this segment of training minutes. And we'd like to thank Holmatra for sponsoring this
