Life cut short by severed lifeline: OSHA demands action
In a new OSHA alert, the agency warns that lifelines can be severed by an exposed edge DURING a fall! When anchored properly, lifelines are meant to prevent a fall or stop workers from reaching a lower level. Now OSHA wants you to know that a worker wearing a personal fall arrest system may still face a fall hazard. That’s because metal and concrete edges can cut a lifeline!
The latest hazard alert in English and Spanish (OSHA 4414 and OSHA 4415) is prompted by a recent investigation. OSHA found that a worker using a personal fall arrest system was killed in a fall incident. However, the evidence indicated the lifeline was damaged during the fall, not before. OSHA explains that any open side or edge of a floor, roof, deck, platform, or formwork creates this hazard. A lifeline or lanyard could be cut if it contacts that sort of edge during a fall.
Read the fine print
Believe it or not, OSHA’s fall protection regulations address this issue. Both 29 CFR 1910.140 and 1926.502 explain that lifelines must be protected against being cut or abraded. They also mandate that personal fall arrest systems be inspected prior to each use for wear, damage and other deterioration and that defective components be removed from service. Appendix G to 29 CFR 1926 Subpart R has similar wording.
The hazard alert also mentions ANSI Z359.14 - 2021, Safety Requirements for Self‑Retracting Devices for Personal Fall Arrest and Rescue Systems.
Check the label on your lifeline/lanyard
OSHA recommends that you select lifelines and lanyards specifically designed to resist cuts and abrasions and follow the manufacturer’s instructions for use. In fact, some manufacturers have lifelines and lanyards with the “LE” (leading edge) or similar designation. These products are designed specifically for bearing against an edge during an arrest.
For example, some manufacturers have developed self-retracting lanyards (SRL) designed for use around exposed edges (SRL-LE).
Assess the work area and plan ahead
According to OSHA, even when SRL-LE products are used, employers must conduct a safety evaluation and identify where additional protection against sharp or abrasive edges may be needed. The hazard alert offers five suggestions:
- Identify potentially hazardous edges;
- Avoid working in areas where lifelines could contact potentially hazardous edges in a fall;
- Find ways to prevent having anchors at feet level;
- Cover exposed edges in the fall zone to protect lifelines and lanyards; and
- Ensure the protective covering will not be moved by the lifeline or lanyard sliding across it.
If covering the edge is not feasible, OSHA recommends:
- Limiting the fall distance, or
- Using another method to avoid lanyard/lifeline contact with the edge.
Train your workers
Finally, OSHA calls for you to train workers so that they’re aware of the danger and can prevent edge contact and minimize swinging falls. In other words, train your workers:
- Where exposed edges are on the worksite;
- That exposed edges may damage or cut lifelines;
- To follow the manufacturer’s instructions when anchoring SRL at feet level;
- To anchor SRLs vertically overhead when possible;
- To keep a safe distance from the overhead anchor point; and
- To spread out multiple lifelines, when possible, so workers can use the closest lifeline.
Be sure to train workers in a language and vocabulary they can understand.
Keys to remember
It’s not enough to put personal fall arrest systems on your workers and hope falls are prevented. OSHA cautions you that exposed edges can damage or sever lifelines and lanyards. However, a new hazard alert offers ways to combat the hazard.
