As part of 3M Fall Protection’s on-going commitment to delivering high quality safety equipment, we are notifying our customers of the following information related to the 1110790-96 Delta™ Arc Flash (AF) Harnesses & ExoFit NEX™ Arc Flash (AF) Harness portfolio. Recent testing of 1110790 AF Delta Harnesses and certain part numbers within the Exofit NEX AF harness portfolio returned negative test results on some units. Specifically, the ASTM F887 Arc Flash standard requires that all non-structural components extinguish within 15 seconds. It should be noted that there is variability in Arc Flash testing of webbing-based products. Although not fully understood, it can stem from several contributing factors including positioning, webbing gap to the test torso, environmental elements, arc path, input energy and other possible sources.
