  • Do You Cut the Rocker or Not?

    Received this interesting email from a firefighter asking for my opinion getting a purchase point along the rocker during dash and firewall movement. This is related to the recent Univ of X article on this subject. Thought I'd share it with this Forum to get some other opinions.

    Question:
    Hello Mr. Moore, I'd like to start by congratulating you on your excellent articles and knowledge that you present each month in Firehouse Magazine, its usually one of the first articles I flip to!

    I have recently attended several New Vehicle Rescue Updates, taught by National Rescue Institute in New Hampshire. After reading your fine article on anchor points for a dash roll, i.e. pinching/poking through the rocker channel for a base point for the ram. In the classes I attended, we were cautioned NOT to breach the rocker channel, whereas some newer vehicles contain fuel and electrical lines in this very spot.

    How does the information provided in your article relate to these newer vehicle designs? Or are there alternative methods of creating a bite point for a ram?

    My Reply:
    I completely agree that rescuers should make the effort to not cut or tear into the rocker channel when rolling or jacking a dash. Do what you can to keep this thing together is my advice. When all else fails, you could consider cutting it but more as a last resort than a standard practice.

    Now, I have yet to find a vehicle built that actually runs the fuel and/or electric lines "inside" or "through" the hollow rocker channel. I believe this is a major misconception. These lines can lay right on the rocker under the trim piece or carpeting, or they can be underneath the rocker running along the floorpan. They can also be along side it or on top of it, but I just don't find the gasoline and electric lines "inside" the rocker.

    It's no matter though because what your instructors are really trying to say is that the lines are so close to the rocker that cutting the rocker would in fact cut the lines. So, take it from there!!

    Same here as far as encountering a fuel line in a rocker channel. But, as I always tell people when we are talking about such things, I never take anything for granted. If I had to cut the rocker, I would do so, providing that I had the power disconnected from the battery and sufficient fire protection present "just in case." However, I would avoid cutting the rocker for another reason, that being structural integrity of the vehicle.

    The integrity is already compromised by the crash damage. Even though the vehcile has been stabilized, cutting one of the structural members will likely change how the vehicles weight is distributed and could create some added problems that weren't there before. If I really needed a purchase point on the rocker and could not use a "ram jig", I would probably use the Amkus trick of crimping the rocker with the spreader and then using it hold the base of the ram as I rolled the dash. Before I did that, I might try driving a Haligan point into the rocker and using the duck bill first.

      GM,Ford,and Chrysler all run their fuel lines in close proximity to the rocker panel.Either pinching or cutting the rocker COULD compromise the lines.Both Richard and Ron are well aware of this.My take on the issue is get friendly with either a local mechanic,dealership,or salvage yard.Go check out various types of vehicles.Every incident we respond to presents us with a new set of challenges.The more prepared we are,the more positive the outcome.This forum is a wonderful tool to bring all extricators up another notch on the ladder.As a result of all of your efforts I am constantly adding more "tools" to my toolbox.When I can I try to add to yours.Many of you see more light duty incidents than I.However due to location I probably see more HD incidents than most of you.By playing off everyones strong points our "customers"are the ultimate winners.Thanks to all,and keep posting.T.C.

        If you do decide to cut into the actual rocker channel of a vehicle, realize that it is an 'point-of-no-return' decision. Once cut, you can't put it back together again.

        Make sure that before you cut, you have a Plan B for what to do when that doesn't work. Now you'll have a weakened, two-piece rocker channel that may actually hinder you rather than help you.
