Lanyards & Lifelines

Lanyards and lifelines are the connecting links between a worker's full body harness and the anchorage point — the critical middle component of the personal fall arrest system that determines how far a worker falls before being stopped and how much force is transmitted to the body during arrest. Selecting the right lanyard for the application is not optional; it directly affects both fall clearance requirements and worker safety outcomes. WC Safety reviews MSA Safety's complete lanyard and lifeline lineup, including energy absorbing lanyards, twin-leg Y-lanyards for 100% tie-off, and temporary horizontal lifeline systems for multi-worker fall protection on elevated work surfaces.

Energy absorbing lanyards are the standard connecting device for applications with adequate fall clearance above a lower level. A 6-foot energy absorbing lanyard, when activated during a fall, deploys a shock pack that decelerates the worker gradually, limiting peak arresting force to 900 pounds (the ANSI Z359.13 Class 2 limit) while adding up to 3.5 feet of deceleration distance to the total fall. The total fall clearance required for a 6-foot lanyard — accounting for free fall distance, deceleration distance, harness elongation, and worker height — typically exceeds 18 feet. When fall clearance is insufficient, a self-retracting lifeline is the appropriate alternative.

Twin-leg Y-lanyards provide 100% tie-off capability — the ability to maintain continuous connection to an anchorage at all times, even while transitioning between anchor points. OSHA requires 100% tie-off for workers on elevated walking-working surfaces where movement between anchor points requires disconnection from the primary anchor. MSA twin-leg lanyards feature two independent legs with snap hooks that connect to separate anchor points, allowing the worker to clip to the next anchor before releasing the previous one. Each leg contains its own energy absorber so that fall arrest capability is maintained independently on each connection.

Snap hook compatibility is a critical safety consideration when selecting lanyards. OSHA prohibits the use of non-locking snap hooks and requires that all snap hooks be self-closing, self-locking, and require two distinct actions to open — preventing accidental disengagement (rollout) during work. MSA lanyards use double-action snap hooks that comply with ANSI Z359.1 and OSHA 1910.140 requirements. Snap hook size must be matched to the D-ring or anchor fitting being connected — MSA provides clear compatibility guidance to prevent cross-loading or rollout in field configurations.

Temporary horizontal lifeline systems extend fall protection coverage across a work area when multiple workers need protection simultaneously, or when the work task requires horizontal travel that makes individual vertical anchorage points impractical. MSA's cable temporary horizontal lifeline systems can span up to 60 feet between end anchors and accommodate multiple workers at calculated intervals, providing walking-working surface fall protection for rooftops, structural steel erection, and elevated floor work. End anchors, intermediate supports, and tensioning hardware are included in complete system configurations.

Lanyard inspection before each use is required by OSHA and should cover all webbing and cable components for cuts, abrasion, chemical damage, and UV degradation; all hardware for corrosion, deformation, and proper snap hook function; and the energy absorber pack for any signs of prior deployment. A deployed energy absorber — indicated by torn stitching or extended pack length — means the lanyard was involved in a fall arrest event and must be removed from service immediately. MSA lanyards include clear deployment indicators that make field inspection straightforward.

WC Safety reviews MSA energy absorbing lanyards in single-leg and twin-leg Y-configurations, in web and cable materials, and in standard and leading-edge-rated versions. We also stock complete MSA temporary horizontal lifeline system kits for multi-worker protection on open elevated surfaces.

Frequently Asked Questions

What are lanyards and lifelines used for?

Linking the harness to an anchor, a lanyard uses a shock pack to absorb energy during a fall, and it operates together with the harness, connector, and anchorage.

What anchor strength does OSHA require?

An anchorage used for fall arrest needs to carry 5,000 pounds per attached worker, or else be engineered for a safety factor of two or more under a qualified person.

Self-retracting lifeline or shock-absorbing lanyard - which should I use?

With its quick lock and shorter free fall, an SRL helps at lower heights, whereas a shock-absorbing lanyard wants more clearance below for the energy pack to open fully.

How much fall clearance do I need?

Tally connector length, deceleration distance, harness stretch, the worker's height, and a safety margin; that combined figure must sit under the distance to the level below.

How often must lanyards and lifelines be inspected?

Inspect them ahead of each use, and have a competent person log a documented inspection at least annually, exactly as ANSI Z359 prescribes.

When should I retire fall-protection equipment?

Retire any piece after a fall-arrest event, and likewise when webbing is cut or frayed, hardware turns bent or corroded, or load-impact indicators have deployed.

What makes a complete fall-arrest system?

Anchorage, body harness, and connector - whether that connector is a lanyard or self-retracting lifeline - together form the ABC of fall protection and serve as a set.

At what height is fall protection required?

By OSHA, the usual triggers are 6 feet for construction and 4 feet for general industry at unprotected edges, with lower points around dangerous equipment.

How do I choose an anchor point?

Opt for a rated, compatible anchor and position it overhead when possible; an overhead anchor reduces both the arrest distance and dangerous swing-fall.

Does fall-protection equipment expire?

There is no preset expiration date, so heed the manufacturer's guidance and retire whatever harness or device fails inspection or has been subjected to a fall.
