cut and separate the wires one at a time with handheld cutters. Be aware that cutting the wires may deploy the SRS.

26

Fender crush technique

crushing the fender with hydraulic spreaders to gain access to the door hinges for cutting or spreading, and door removal. Completing this technique requires one arm of the spreaders to be placed in the wheel well behind the shock/ strut tower, and the other on top of the fender. Fitting the spreader tip edge into the space between the fender and the hood, as well as raising the back end of the spreader slightly above 90 degrees will help prevent the tool from slipping.

27

technique used to create a wider door opening on two door vehicles.

* Reciprocating saw
* Spreaders
* Air chisels

30

Fourth door conversion

A technique that creates an alternate opening on a panel van or work van that only has one operating door for cargo loading and off-loading. Cuts are made between the B and C posts in the side panel, creating a large opening for rescue access and victims removal.
