Which part of the AS/NZS 1891 series covers the selection, use, and maintenance of industrial fall-arrest and travel restraint systems?
Answer: AS/NZS 1891.4
AS/NZS 1891.4 is the standard for selection, use, and maintenance of industrial fall-arrest systems and devices, which includes travel restraint equipment.
How frequently must a travel restraint lanyard be inspected according to AS/NZS 1891.4?
Answer: Before each use by the worker, and periodically by a competent person
AS/NZS 1891.4 requires fall protection equipment to be inspected by the user before each use, with periodic detailed inspections carried out by a competent person.
What must happen immediately if a travel restraint lanyard shows signs of cuts, fraying, or chemical contamination?
Answer: It must be tagged, removed from service, and assessed by a competent person before any further use
Damaged fall protection equipment must be immediately removed from service and must not be used again until assessed by a competent person or destroyed.
Why is the location of the anchor point critical when designing a travel restraint system?
Answer: Its position combined with the lanyard length defines the worker's maximum reach toward the fall edge
The anchor point location and lanyard length together determine the radius within which the worker can move, and therefore whether they can physically reach the fall hazard.
When used in a travel restraint system, which type of lanyard is most appropriate?
Answer: A fixed-length non-energy-absorbing lanyard, as no fall arrest forces should be generated
Since a correctly used travel restraint system prevents falls entirely, energy-absorbing lanyards are unnecessary, and a plain fixed-length lanyard avoids the extra deployed length of an energy absorber.
Under the Work Health and Safety Regulations, what mandatory document must be prepared before commencing high-risk construction work involving working at heights above 2 metres?
Answer: A Safe Work Method Statement (SWMS)
The WHS Regulations require a SWMS to be prepared before any high-risk construction work, including work at heights above 2 metres, is performed.
How does working on a sloped roof surface affect lanyard length calculations in a travel restraint system?
Answer: A steeper slope generally requires a shorter lanyard as the worker can reach the edge more quickly
On a sloped surface, the geometry means a worker can reach the fall edge sooner for a given lanyard length, so calculations must account for slope angle to ensure the worker cannot access the edge.
