Independent practice for the knowledge behind RIIWHS204E Work safely at heights: falls duties, the hierarchy of fall controls, scaffolds and EWPs, ladders, fall arrest and rescue. There is no state exam: a registered training organisation assesses theory and a practical demonstration. Rules that differ by state, such as the Victorian OHS Regulations, name the state. The 20 questions, 80% pass mark and 30 minutes are ExamRoo practice settings, not an official format.

5 Most Common Work safely at heights (RIIWHS204E) Sample Questions & Answers

Preview 5 practice questions with answers and explanations that name their source.

Sample Question 1 of 5Fall control duties

Under the model WHS Regulation, what must a person conducting a business or undertaking (PCBU) ensure, so far as is reasonably practicable, about any work that involves a risk of a fall from one level to another?

AIt is carried out from a mobile scaffold with locked castors.
BIt is carried out from a ladder secured at both ends.
CIt is carried out by workers wearing a full body harness.
DIt is carried out on the ground or on a solid construction.
Answer & Source:

Working on the ground or on a solid construction is the first step because it eliminates the fall hazard. Issuing a harness is a lower-order control and comes later in the hierarchy. The duty is set out in WHS Regulation clause 78 and explained in the falls Code of Practice.

Sample Question 2 of 5Fall control duties

A PCBU cannot eliminate a fall risk by working on the ground or on a solid construction. Which control must be provided first if it is reasonably practicable?

AA work positioning system
BA fall prevention device
CA fall arrest system
DAn administrative control such as a permit
Answer & Source:

The model WHS Regulation requires a fall prevention device first, then a work positioning system, then a fall arrest system. A work positioning system or fall arrest system is only provided when the higher control is not reasonably practicable. Administrative controls support these but do not replace them.

Sample Question 3 of 5Fall control duties

Under the model WHS Regulation, when may a PCBU rely on a fall arrest system as the control for a fall risk?

AWhen the work is more than 4 metres above the ground
BWhen the worker holds a high risk work licence
CWhen higher-order controls are not reasonably practicable
DWhen a harness is cheaper to supply than a guardrail
Answer & Source:

Fall arrest systems do not prevent a fall; they only reduce its effects, so they rank last of the three. They are used where neither a fall prevention device nor a work positioning system is reasonably practicable. Height alone or cost does not decide the control.

Sample Question 4 of 5Safe work method statement

Under the model WHS Regulation, construction work is high risk construction work, needing a safe work method statement (SWMS), if it involves a risk of a person falling more than how far?

A1.5 metres
B2 metres
C3 metres
D4 metres
Answer & Source:

Any construction work with a risk of a person falling more than 2 metres is high risk construction work, so a SWMS must be prepared before it starts. The 4 metre figure belongs to scaffolds and the 1.5 metre figure to trenches. Both are common mix-ups.

Sample Question 5 of 5Safe work method statement

A SWMS for work with a risk of falling more than 2 metres states that only administrative controls or personal protective equipment will be used. What must the SWMS also describe?

AThe names of workers who have used the system before
BThe cost of each higher-order control that was rejected
CThe manufacturer of each item of protective equipment
DAll control measures considered in choosing the controls
Answer & Source:

Where only administrative controls or PPE are chosen for work above 2 metres, the SWMS must show all the control measures that were considered, including the fall protection hierarchy in the regulation. This stops lower controls being picked without justification. Cost is not a listed requirement.
