Total Sidewall Removal by ProQuest

VIEWS: 35 PAGES: 3

There are four different overall strategies that could be used to remove the entire sidewall of this vehicle. One strategy would be to have crews remove each door and the B-pillar individually. Another plan would be to have the front door opened and removed then the rear door opened and removed along with the B-pillar. A third technique would assign rescuers to open the jammed rear door at the latch then attack the jammed front door at its hinges.
