Safety Lanyard Types and How to Choose the Right One
A safety lanyard looks simple, but the wrong type can leave too much fall distance, load the body incorrectly, or fail to control movement at the edge. The right choice starts with the task, the harness, the anchor, and the manufacturer’s instructions.
Safety lanyards are part of a larger fall protection system. They do not work alone. A suitable setup includes a compatible full body harness, an appropriate anchor point, correct connectors, enough clearance, and a trained person using the equipment as intended.
Shock-absorbing lanyards reduce arrest forces during a fall
Shock-absorbing lanyards are designed for fall arrest. If a worker falls, the energy absorber deploys to reduce the force transferred to the body and anchor system.
They are commonly used when working at height where a fall could occur, such as:
Steel erection
Roof work
Scaffold access
Elevated platforms
Maintenance near unprotected edges
These lanyards typically connect to the dorsal D-ring on a full body harness. The other end connects to a rated anchor or lifeline system. Some versions are single-leg, while twin-leg versions allow continuous attachment when moving between anchor points.
Clearance is critical. The lanyard length, absorber deployment, worker height, harness stretch, and safety margin all add up. If there is not enough fall clearance, another system may be needed, such as a self-retracting lifeline.
Positioning lanyards support hands-free work
Positioning lanyards help hold a worker in place while they work with both hands. They are often used on poles, towers, formwork, and rebar structures.
These lanyards usually connect to side D-rings on a harness or belt designed for work positioning. They are not meant to arrest a free fall unless the manufacturer clearly states that they are part of a fall arrest system.
A positioning setup should limit movement and keep the worker supported. In many tasks, it must be paired with a separate fall arrest system. For example, a worker may use a positioning lanyard to lean into a work area while also staying connected to an overhead fall arrest anchor.
Restraint lanyards keep workers away from the hazard
Restraint lanyards prevent a worker from reaching a fall edge in the first place. They are used when the work can be done without exposing the person to a fall.
This type of lanyard must be short enough, or adjusted correctly, so the user cannot step past the safe limit. A restraint system is not designed to catch a fall. Its value comes from stopping access to the fall hazard.
Common uses include flat roof maintenance, loading areas, and elevated walkways where a fixed anchor point can keep the worker within a safe zone.
Compatibility matters across the whole system
A lanyard must be compatible with every part of the fall protection system. Check:
Harness attachment points
Anchor rating and location
Connector gate type and size
Lanyard length and adjustment range
Edge exposure and swing fall risk
Environmental conditions, such as heat, chemicals, sharp edges, or abrasive surfaces
Connectors should close and lock properly without forcing or side-loading. Avoid mixing equipment unless the manufacturer allows it. Even parts that look similar may not be tested together.
Inspect lanyards before each use
Before using any lanyard, inspect it carefully. Remove it from service if there is doubt about its condition.
Look for:
Cuts, burns, fraying, or broken fibres
Torn stitching or pulled seams
Deployed shock absorbers
Cracked, bent, corroded, or distorted hardware
Damaged labels or missing identification
Contamination from chemicals, paint, oil, or excessive dirt
Connectors that do not close, lock, and release correctly
Follow the inspection schedule in the instructions. Some equipment also requires periodic inspection by a competent person.
How to choose the right lanyard for the task
Start with the work method, not the product catalogue.
Choose a shock-absorbing lanyard when the task needs fall arrest and there is enough clearance for the system to deploy safely.
Choose a positioning lanyard when the worker needs support while working in place, and confirm whether a separate fall arrest system is also required.
Choose a restraint lanyard when the safest plan is to prevent access to the edge or opening.
Then confirm the details with the manufacturer’s instructions. Check the approved attachment points, user weight range, required clearance, connector compatibility, anchor requirements, and limits of use.
The safest lanyard is the one that matches the real task, connects correctly to the harness and anchor, passes inspection, and is used exactly as the manufacturer intended.
