Lanyard Clipped to the Guardrail During a Fall
During facade work at a 16-storey office building, a worker on a dual-point platform clips his fall-arrest lanyard to the platform’s aluminium guardrail because the independent safety rope is 1.2 m behind him and he says it restricts movement. The platform is at 11/F. A timber offcut falls onto the platform floor; the worker stumbles against the guardrail, the guardrail deforms, and he falls over the edge. His lanyard arrests him about 1.8 m below the platform. He is conscious but dangling, complaining of dizziness and numbness in his legs. His colleague is on the platform and wants to climb over and pull him back by the lanyard. The platform’s emergency lowering function is working. The safety rope is intact and runs from the roof rig to a separate anchor. Wind is light. The site rescue plan is in the site office, but no rescue kit is on the roof.
1. Identify the fall-protection failures and explain why the guardrail is not an anchorage.

The primary failure is that the worker connected his fall-arrest lanyard to the platform guardrail instead of the independent safety rope. A guardrail is a collective edge-protection barrier; it is not designed, tested or marked as a personal fall-arrest anchorage. It can deform, detach or tip when subjected to the dynamic force of a falling person. In this case the guardrail did deform, which confirms that it could not provide a reliable anchorage. Connecting to the guardrail also created a short lanyard length and a likely swing-fall hazard against the facade or platform structure. The independent safety rope existed and was intact, but the worker chose not to use it because of restricted movement; that is a procedural and supervision failure, not a reason to change the anchorage. The harness should have been checked for fit and correct attachment, and the lanyard should have been connected to a suitable anchorage point on the independent safety rope, with the worker positioned to avoid slack and swing-fall. The platform itself should not be used as the fall-arrest anchor unless the manufacturer specifically provides a certified anchorage point.
2. What are the immediate rescue priorities, and how should suspension trauma be managed?

The colleague should not climb over the guardrail or pull the worker by the lanyard; that could release the arrested fall, damage the deformed guardrail further or cause a second fall. The first priorities are to call emergency services, alert the site rescue team, secure the platform and keep the worker talking. The worker should be reached using a planned rescue method, preferably from the independent safety rope or a dedicated rescue system, with a trained rescuer attached to a separate anchorage. The platform’s emergency lowering function may help bring the platform closer to a safe access point, but it should be used only if it reduces the suspension and does not drag the worker or increase the fall height. Suspension trauma is a risk: the worker should be kept as horizontal as possible after rescue, not forced to stand or walk, and should be monitored for dizziness, sweating, nausea and loss of consciousness. Medical assessment is required even if he appears to recover. The rescue should be recorded and the equipment quarantined for inspection.
3. What preventive and reporting actions should follow the incident?
Read the worked answer
The platform and harness equipment should be withdrawn from service pending inspection. The deformed guardrail, lanyard, harness and safety rope should be examined by a competent person, and the platform should not be used until repaired and re-examined as required. The incident should be reported to site management and the contractor’s safety personnel, recorded in the logbook and accident records, and notified under the applicable statutory accident or dangerous-occurrence procedure. A investigation should establish why the worker believed the safety rope restricted movement and why supervision did not correct the attachment. The rescue plan should be revised to include a roof-level rescue kit, trained rescuers, clear communication and a practice drill. Toolbox talks should cover correct anchorage, lanyard length, swing-fall, harness fitting and the worker’s right to stop work. The site should also review housekeeping, since the falling timber offcut contributed to the event.
