Extrication "Quick Tip" #9 (X Method)

When it comes to extrications involving "big rigs" our methods must change due to vehicle size, load, and weight. This leads into the X Method for stabilizing tractor trailers (rolling). Obviously if lifting is involved then struts, more cribbing, etc. will be used. I will often see crews attempting to control horizontal movement (rolling) by small wedges or chalks. After training one of the ways we found to increase stabilization on the horizontal plane is with (2) 48'' 4x4s per side (as shown). The X method controls rolling to the front or rear due to the directional pressure of 4x4's placed in this way. This method can be coupled with wedges under the tires but has proved to be a quick method to control the roll. Just another tool for the toolbox.
