Working at Heights Travel Restraint Systems 2

Question 1

Which part of the AS/NZS 1891 series covers the selection, use, and maintenance of industrial fall-arrest and travel restraint systems?

Accepted Answer

AS/NZS 1891.4

Answer

AS/NZS 1891.1

Answer

AS/NZS 1891.2

Answer

AS/NZS 1891.3

Question 2

How frequently must a travel restraint lanyard be inspected according to AS/NZS 1891.4?

Accepted Answer

Before each use by the worker, and periodically by a competent person

Answer

Weekly by a competent person on site

Answer

Monthly by the equipment manufacturer

Answer

Annually by a certified height safety inspector

Question 3

What must happen immediately if a travel restraint lanyard shows signs of cuts, fraying, or chemical contamination?

Accepted Answer

It must be tagged, removed from service, and assessed by a competent person before any further use

Answer

It may still be used for travel restraint since it does not arrest falls

Answer

It should be reported and replaced at the next scheduled maintenance cycle

Answer

It may remain in use if a supervisor inspects and approves it verbally

Question 4

Why is the location of the anchor point critical when designing a travel restraint system?

Accepted Answer

Its position combined with the lanyard length defines the worker's maximum reach toward the fall edge

Answer

It determines the colour-coding classification of the system

Answer

It must be directly below the worker to prevent an upward pull on the harness

Answer

It must be located at ground level to allow easy lanyard adjustment

Question 5

When used in a travel restraint system, which type of lanyard is most appropriate?

Accepted Answer

A fixed-length non-energy-absorbing lanyard, as no fall arrest forces should be generated

Answer

An energy-absorbing lanyard to limit peak forces if the restraint is loaded

Answer

A rope-grab lanyard for continuous length adjustment during work

Answer

A retractable self-retracting lanyard for maximum freedom of movement

Question 6

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?

Accepted Answer

A Safe Work Method Statement (SWMS)

Answer

A Job Hazard Analysis (JHA) submitted to the regulator

Answer

A certificate of currency for public liability insurance

Answer

A manufacturer's declaration of conformity for all equipment

Question 7

How does working on a sloped roof surface affect lanyard length calculations in a travel restraint system?

Accepted Answer

A steeper slope generally requires a shorter lanyard as the worker can reach the edge more quickly

Answer

Slope has no effect; calculations are based solely on vertical height

Answer

A steeper slope always permits a longer lanyard because the anchor is positioned higher

Answer

Lanyard length is only affected by the anchor height above ground level
