Double-leg arc-flash resistant shock-absorbing lanyard DBI-SALA 3M 6 ft 1246528C

Fall protection: the arc-flash resistant double-leg lanyard for hot work

3M purchase code: 7012817320, model: 1246528C

This 6 ft double-leg lanyard with built-in energy absorber is designed for work exposed to arc-flash, welding or grinding hazards. Its arc-resistant construction and two-leg configuration protect the worker while allowing permanent attachment when moving at height.

It is fitted with three small zinc-plated spring snap hooks, self-locking, with a 3/4 in / 19 mm gate opening. The double configuration provides 100 % tie-off: one leg is connected to the new anchorage before the other is released, so the worker stays connected at all times.

Its abrasion-resistant Kevlar and Nomex webbing offers excellent resistance to heat and sparks. The common end connects to the worker's harness.

In electrical work, welding and industrial maintenance across Canada, the combined prevention of falls and arc-flash hazards is essential. This 6 ft lanyard links the worker to anchorage points while resisting arc-flash and absorbing the energy of a fall. The internal energy absorber deploys gradually to reduce arrest forces transmitted to the body. The 3M DBI-SALA range combines durability and reliability, delivering a solution that meets the strictest safety standards.

Choosing this arc-flash resistant lanyard means investing in professional-grade equipment suited to electrical and hot work environments.

Important note: In the event of a fall, the absorber deploys to limit arrest forces on the body. Never connect both legs to the same anchorage point to pass an obstacle if it leaves a free leg attached to the harness without the absorber engaged.

We offer a complete range of equipment suited to different work configurations:

1. Harnesses for fall protection.
2. Lanyards.
3. Lifelines & self-retracting straps.
4. Ropes and vertical rope grabs.
5. Connectors and anchors.
6. Roofer kits.
7. Tripods and confined-space lifelines.
8. Horizontal lifeline.
9. Fall protection accessories.

Product highlights: a rugged design for hot work

• This 3M lanyard stands out for its arc-flash resistance and its rugged build. Its main features include:
• Double configuration (2 legs): 100 % tie-off to stay attached while moving between anchorage points.
• Arc-flash resistant: designed for hot work, welding, grinding and electrical work.
• Internal energy absorber: controlled tear-out device that dissipates kinetic energy during a fall.
• Three small zinc-plated spring snap hooks: self-locking, with a 3/4 in / 19 mm gate opening, for a safe and quick connection.
• Kevlar and Nomex webbing: flame-resistant materials offering excellent resistance to heat and sparks.
• 6 ft (1.83 m) lanyard: length suited to common work at height.

How to install and use your double-leg lanyard

Connect the common end fitted with the energy absorber to the dorsal attachment point (D-ring) of your safety harness. Then attach one leg to an approved anchorage point. When moving, first connect the second leg to the new anchorage, check that it is locked, then release the first. Make sure the snap hooks are properly locked at every move.

How to maintain your fall protection equipment

Careful maintenance extends the life of your lanyard and keeps you safe. Before each use, inspect both legs of the webbing for cuts, burns or signs of excessive wear. Check that the self-locking snap hooks work properly. Clean the lanyard with lukewarm water and mild soap if soiled, and let it air-dry away from direct heat sources. Store it in a cool, dry place, away from UV rays and chemicals.

Understanding the fall clearance window

Before using this energy-absorbing lanyard, calculate the fall clearance, that is, the free space required below the anchorage point to arrest a fall before the worker strikes the ground or an obstacle. This clearance window adds up from several elements: the length of the lanyard, the deployment of the energy absorber, the height of the worker, the dorsal D-ring slide and a safety margin. A miscalculation is one of the most common causes of serious injuries at height, even with compliant equipment.

Example for this 6 ft lanyard: the lanyard (6 ft) plus the absorber deployment (4 ft) plus the worker height (6 ft) plus a safety margin (1.5 ft) give a total clearance of about 17.5 ft (5.3 m) below an overhead anchorage. In low-clearance situations, choose a self-retracting lifeline instead.

FAQ: Frequently asked questions about the arc-flash resistant lanyard

Is this lanyard compliant with Canadian standards?

Yes, this product complies with the CSA Z259.11 standard, ensuring its compliance for construction sites and industrial environments in Canada.

What is the capacity of this lanyard?

This lanyard is designed for a worker whose total weight (including tools) does not exceed 254 lb (115 kg).

Why choose an arc-flash resistant lanyard?

Its Kevlar and Nomex webbing resists heat and sparks, making it suited to welding, grinding and electrical work where an ordinary lanyard could be damaged.

What is the required fall clearance with this 6 ft lanyard?

Adding the lanyard (6 ft), the absorber deployment (4 ft), the worker's height (6 ft) and a safety margin (1.5 ft), you need about 17.5 ft (5.3 m) of clearance below an overhead anchorage. At low height, choose a self-retracting lanyard instead.

What happens if my anchorage is at foot level?

This is the most dangerous scenario (fall factor 2): free fall can reach twice the length of the lanyard. This energy-absorbing lanyard is designed to dissipate the energy of a severe fall and reduce arrest forces, making it a suitable choice when the anchorage is at foot level.

Complementary suggestions for the lanyard:

Beyond fall arrest, equip the worker from head to toe: protect their hands with protective gloves (G100), their eyes with safety eyewear (YA12E90801), and their hearing in noisy areas with earplugs (OA1103) or earmuffs (OPH7A); on a traffic worksite, add a high-visibility vest (VV51).

To complete your fall protection system, combine your lanyard with reliable anchors: a connector (FPA826), an anchor (FPAF075N) or a rugged fixed connector (FPA822); attach it to an ExoFit harness (FPH140100XCAL) or the ExoFit model (FPH140100XCA), and post the obligation sign (ECO130) on site.
