A multifunction NFPA escape and ladder belt having multiple functions for firefighter and rescue worker work. The belt includes a front buckle and right and left side buckles, straps coupling the left and right side buckles to the front buckle and to one another. At least one of said straps includes a stitched loop portion formed with a stitching pattern configured to fail, and for the loop portion to unfold, when the side straps are under a sufficient tension load exceeding the breaking strength of the stitching pattern; that failure will occur before a structural failure in any other element or component of the belt. |
