    ... assuming you mean rolling the dash. There are three basic ways to perform this task.

    1. Pushing w/ Rams
    2. Spreading w/ Spreaders
    3. Pulling w/ Spreaders

    Pushing w/ Rams -
    Place ram in door frame, make a relief cut on vertical section of door frame (about half way between floorboard and bottom of dash). Then do this:

    2. Spreading w/ spreaders -

    Make the same relief cut as you did w/ the rams. Make an additional relief at top/center of front wheel well. Place tips of spreader in the 1st relief cut, and spread away. I prefer this method because it (A)does not push the front bumper of the vehicle against the ground, or any object the front of the car may have run into, and (B)leaves a clear pathway for patient removal.

    3.Pulling w/ the spreaders -

    Wrap one set of hurst chains around the steering column, and the other end around the front axle. Place the spreaders on the hood of the car, and connect the chains like this:

    3.Pulling w/ spreaders (cont.) -

    Then, close the spreaders. I'm not a big fan of this method because it takes a little longer, and there's always the urban legend of the steering column ripping off and gutting the patient (although, I've never actually heard of this happening, it still looks like it could). Like this:

    This was all very quick and basic, and, by no means, all inclusive. I would suggest you check out the University of Extrication, and do some YAHOO searches for more info.

    Of course, you truly can "jack a dash" with a... jack!

    In this case, the sawzall made the relief cut. The JackMate spikes are on the seat mount bracket. A few pumps of the handle and the dash was up.

    ... assuming you mean rolling the dash. There are three basic ways to perform this task.
    Never assume anything. For a couple of reasons: 1. People's definitions of tasks vary greatly around the country/world.

    2. There can be the existance of both terms since there is a slight difference in the end result.

    For example, the number 2 option listed by PA Vol is my definition of "jacking" a dash with options 1 and 3 being my definitions of rolling a dash.

    The image posted by Kbud actually demonstrates my point better in that by 'jacking' a dash, the dash assembly comes off the patient in more of a vertical fashion where the 'roll' takes the dash forward and up.

    Also in my experiences in my area, a car that has had the dash jacked vs rolled generally does not have that 'v' shape to it where the front bumper is on the ground. Again if you look back at Kbud's image you will see what I believe to be a relief cut in the area of the top of the front wheel well. I have found that this 'disconnects' the midsection of the vehicle from the front end and allows the dash to move upward more independently than if that cut were not made. This is particularly useful in the scenario of a vehicle with it's front end against an im-movable object such as a tree, pole, wall, etc.

    If this relief cut is made and the front end does not move as much, you cut the risk of shifting the vehicle when the im-movable object shows its strength when pushed against.

    Hopefully that was just a little bit clearer than mud!

    Just a thought to keep in your head for a future run.

    Stay Safe!

    Sorry, I guess I should have said, "assuming you mean methods to get the dashboard off of the screaming person still trapped in the car."

    PA --

    Not trying to take a shot at you directly. Simply trying to make a point in general using your statement as an example to lead off my soapbox lecture.
