Honeywell has issued an Immediate Stop USE Notice for certain models of Miller MightEvac and MightyLite self-retracting lifelines (SRLs) manufactured within a specific time frame. The notice only affects specifically listed models, with identified manufacturing dates or re-certification dates between October 27, 2016 and October 6, 2018. Models outside of this date range, including new units, are not affected by this notice. If your company uses these SRLs check Table 1 in the attached notice to determine whether your SRLs are affected. If so, they should be removed from service immediately. Honeywell is making arrangements for their return and replacement. That information is forthcoming.
