Continue in the practice tool above to load more questions, 50 at a time.

Question 1Boom-type elevating work platform scope of work and boom length determination

Under the WP high risk work licence, what does the boom length of an elevating work platform primarily determine?

  1. The number of operators permitted in the basket
  2. The frequency of annual inspection intervals
  3. The colour coding required on the chassis
  4. The rated capacity and reach envelope of the platform Correct answer.

Explanation

Boom length is a structural and stability parameter. It sets how far the platform can reach and how much load can be carried at each radius, which is why the licence is defined by boom length rather than basket size or chassis type.

Question 2Boom-type elevating work platform scope of work and boom length determination

A boom-type elevating work platform has a boom length of 11 metres. Which statement about licensing is correct?

  1. The operator needs a WP licence because the boom exceeds 11 metres
  2. A dogging licence is sufficient for this platform
  3. The operator needs a WP licence because the boom is 11 metres or more Correct answer.
  4. No licence is needed because the boom is under 15 metres

Explanation

The WP licence applies to boom-type elevating work platforms where the boom length is 11 metres or more. A machine of exactly 11 metres therefore falls inside the licensing requirement, not outside it.

Question 3Boom-type elevating work platform scope of work and boom length determination

How is boom length defined for the purpose of the WP licence?

  1. The length of the boom structure as specified by the manufacturer Correct answer.
  2. The total travel distance the platform can achieve in one charge
  3. The horizontal distance from the chassis to the basket at full reach
  4. The vertical height from ground level to the basket floor at rest

Explanation

Boom length is a manufacturer-specified dimension of the boom structure itself, not a measured reach or height on site. Regulators use that specified figure to decide whether the machine is a licensable boom-type platform.

Question 4Boom-type elevating work platform scope of work and boom length determination

Which machine is outside the scope of the WP licence?

  1. A scissor lift that raises the platform vertically only Correct answer.
  2. A trailer-mounted boom platform with a 14 metre boom
  3. An articulated boom platform with a 16 metre boom
  4. A self-propelled telescopic boom with a 20 metre boom

Explanation

The WP licence covers boom-type platforms, meaning machines whose platform is positioned by a boom. A scissor lift raises its platform on a vertical scissor stack and is therefore not a boom-type machine, regardless of its working height.

Question 5Boom-type elevating work platform scope of work and boom length determination

Why must an operator confirm the boom length before operating an unfamiliar elevating work platform?

  1. To calculate the fuel consumption for the shift
  2. To decide whether the machine requires a licensed operator and what pre-start checks apply Correct answer.
  3. To determine the tyre pressure setting
  4. To select the correct sling type for lifting loads

Explanation

Confirming boom length tells the operator whether the machine is a licensable boom-type platform and therefore whether a WP licence holder must operate it. It also frames the correct pre-start and inspection regime for that class of machine.

Question 6Boom-type elevating work platform scope of work and boom length determination

Where should an operator find the authoritative boom length for a specific machine?

  1. The daily pre-start checklist
  2. The traffic management plan
  3. The site induction handbook
  4. The manufacturer's identification plate or documentation Correct answer.

Explanation

The manufacturer's plate or documentation states the machine's specified dimensions, including boom length. Site documents may reference the machine but are not the authoritative source for that figure.

Question 7Boom-type elevating work platform scope of work and boom length determination

Which activity is within the scope of work of a licensed boom-type EWP operator?

  1. Positioning the basket to allow a task to be performed at height Correct answer.
  2. Designing the structural tie-down for the platform
  3. Rigging a load onto a crane hook at height
  4. Certifying the machine's electrical installation

Explanation

The licensed operator's core task is to safely position and operate the platform so that work can be carried out at height. Rigging, structural design and electrical certification are separate competencies held by other people.

Question 8Boom-type elevating work platform scope of work and boom length determination

A boom-type platform is rated for a maximum of two people. What does this rating relate to?

  1. The licence class held by the operator
  2. The rated capacity of the platform and its load chart Correct answer.
  3. The boom length of the machine
  4. The wind speed at the time of use

Explanation

The number of people permitted in a basket is part of the platform's rated capacity, which the manufacturer sets and records on the load chart. Boom length affects reach and capacity but does not by itself set the person limit.

Question 9Boom-type elevating work platform scope of work and boom length determination

An operator is asked to use a boom platform to lift a pallet of bricks to a roof. What is the correct response?

  1. Proceed if a spotter watches the load
  2. Proceed if the pallet mass is under the platform's rated capacity
  3. Proceed if the pallet is strapped to the basket rail
  4. Refuse, because elevating work platforms are for personnel and tools, not crane lifting Correct answer.

Explanation

Boom-type elevating work platforms are designed to raise people with their tools and materials, not to act as cranes. Lifting a pallet as a suspended load exceeds the machine's intended purpose and its stability envelope.

Question 10Boom-type elevating work platform scope of work and boom length determination

A platform has a maximum platform height of 12 metres and a maximum outreach of 8 metres. Which dimension is used to establish whether the WP licence applies?

  1. The manufacturer's specified boom length Correct answer.
  2. The combined height plus outreach figure
  3. The 12 metre platform height
  4. The 8 metre maximum outreach

Explanation

Licensing is based on the boom length specified by the manufacturer, not on platform height or outreach figures. Those other dimensions describe performance but do not determine the licence class.

Question 11Boom-type elevating work platform scope of work and boom length determination

Two machines are on site: a 9 metre boom platform and a 13 metre boom platform. How should supervision be arranged?

  1. Both machines may be operated by any trained worker
  2. Neither machine requires a licence if used below 3 metres
  3. Only the 13 metre machine requires a licensed operator Correct answer.
  4. Both machines require a licensed operator because both are boom-type

Explanation

The licensing threshold is a boom length of 11 metres or more. The 9 metre machine falls below that threshold while the 13 metre machine exceeds it, so only the larger machine demands a WP licence holder.

Question 12Boom-type elevating work platform scope of work and boom length determination

An operator must position a boom platform close to a live powerline to complete a task. What is the primary control?

  1. Increase boom length to reach over the lines
  2. Reduce the load in the basket to half capacity
  3. Maintain the legislated safe approach distance and use a spotter Correct answer.
  4. Work only during daylight hours

Explanation

Electrical safety near overhead lines depends on keeping the platform and boom outside the legislated safe approach distance. A dedicated spotter helps the operator maintain that clearance throughout the movement.

Question 13Boom-type elevating work platform scope of work and boom length determination

Why does a longer boom generally reduce the capacity available at the basket?

  1. Longer booms are only permitted with a reduced person count
  2. Longer booms require more hydraulic oil and reduce pressure
  3. Longer booms increase the load moment at a given radius, so capacity must be limited Correct answer.
  4. Longer booms weigh more and increase the machine's stability margin

Explanation

Capacity is governed by the load moment, which is the load multiplied by its distance from the tipping line. A longer boom places the basket further out, raising the moment and forcing a lower permitted load.

Question 14Boom-type elevating work platform scope of work and boom length determination

What does the rated capacity of a boom-type platform represent?

  1. The maximum load the platform can carry at a stated configuration Correct answer.
  2. The maximum wind speed in which the machine may operate
  3. The maximum number of hours the machine may run per day
  4. The maximum slope on which the machine may travel

Explanation

Rated capacity is the manufacturer's declared maximum load for the platform at a specified configuration and radius. It accounts for people, tools and materials combined, and is read from the load chart.

Question 15Boom-type elevating work platform scope of work and boom length determination

An operator is unsure whether a particular task falls within the scope of the WP licence. What is the most appropriate action?

  1. Proceed and note the uncertainty in the shift log
  2. Ask a workmate who holds a rigging licence to take over
  3. Ask the site supervisor to confirm the task and any additional competencies required Correct answer.
  4. Refuse all work until the manufacturer is contacted

Explanation

Scope questions should be resolved through the site's supervision and competency framework before work starts. The supervisor can confirm whether the task is within the licence scope or needs another competency such as rigging or electrical work.

Question 16Boom-type elevating work platform scope of work and boom length determination

Which factor is most relevant when deciding whether a boom platform can be used on a sloping site?

  1. The manufacturer's maximum permitted slope for the machine Correct answer.
  2. The number of outriggers painted on the chassis
  3. The age of the operator's licence card
  4. The colour of the machine's warning decals

Explanation

Manufacturers specify maximum slope and ground-bearing limits for each machine. Operating beyond those limits compromises stability regardless of how the platform is otherwise set up.

Question 17Boom-type elevating work platform scope of work and boom length determination

A boom platform will be used in gusty conditions. What should the operator check first?

  1. The length of the boom relative to the site boundary
  2. The number of staff available to hold the basket steady
  3. The manufacturer's maximum wind speed for the machine and the basket's wind area Correct answer.
  4. The colour of the wind sock at the site entrance

Explanation

Each machine has a manufacturer-specified wind speed limit, and the basket's sail area affects how the platform responds to gusts. Operation must stop when measured conditions exceed those limits.

Question 18Boom-type elevating work platform scope of work and boom length determination

What is the purpose of the emergency lowering system on a boom-type platform?

  1. To raise the machine onto its outriggers
  2. To increase the boom length during normal operation
  3. To allow the basket to be brought down if the primary power fails Correct answer.
  4. To speed up the descent at the end of a shift

Explanation

The emergency lowering function provides a controlled way to return the platform to ground level if the primary power or controls fail while people are aloft. Operators must be trained in its use during familiarisation.

Question 19Boom-type elevating work platform scope of work and boom length determination

When a boom platform is set up on a suspended concrete slab, which check is essential before elevating?

  1. Confirming the slab's construction date only
  2. Confirming the slab's paint colour and finish
  3. Confirming the slab's expansion joint spacing
  4. Confirming the slab's load capacity and the machine's point loads Correct answer.

Explanation

A suspended slab must be able to carry the machine's mass plus the imposed load from people and tools at each point of contact. Point loading under outriggers or wheels is often the governing case.

Question 20Boom-type elevating work platform scope of work and boom length determination

A task requires the operator to reach a point 15 metres horizontally from the chassis. The machine's load chart shows a lower capacity at that radius. What must the operator do?

  1. Add a second person to counterbalance the basket
  2. Ignore the chart because the boom is under 20 metres
  3. Extend the boom fully before moving the basket outward
  4. Reduce the basket load to stay within the charted capacity at that radius Correct answer.

Explanation

Capacity falls as radius increases, so the load in the basket must be reduced to whatever the chart permits at the working radius. Exceeding the charted figure at any radius risks structural failure or tipping.

Question 21Boom-type elevating work platform scope of work and boom length determination

An operator notices the machine's data plate is missing and the boom length cannot be confirmed. What is the safest course of action?

  1. Estimate the boom length by pacing it out and proceed
  2. Operate it only for short lifts under 5 metres
  3. Assume it is below the threshold because it looks small
  4. Take the machine out of service until its specification is verified Correct answer.

Explanation

Without a verified specification the licence class and capacity limits cannot be established. The machine should be withdrawn from service until the manufacturer or a competent person confirms its dimensions and ratings.

Question 22Boom-type elevating work platform scope of work and boom length determination

Why is the load moment, rather than the total basket mass alone, the governing measure for platform stability?

  1. Because mass alone ignores the distance of the load from the tipping line Correct answer.
  2. Because load moment includes the operator's licence class
  3. Because load moment is measured in kilograms
  4. Because mass alone overstates the effect of gravity

Explanation

Stability depends on the turning effect of the load, which is the mass multiplied by its horizontal distance from the tipping line. A lighter load at a long radius can create a greater moment than a heavier load close in.

Question 23Boom-type elevating work platform scope of work and boom length determination

A supervisor asks an operator to use the platform's boom to push a section of formwork into alignment. How should the operator respond?

  1. Comply if a second operator guides the formwork
  2. Refuse, because side loading the boom is outside the machine's design use Correct answer.
  3. Comply if the formwork is light enough to move by hand
  4. Comply if the boom is fully retracted first

Explanation

Boom platforms are designed for vertical and controlled reach movements, not for pushing or pulling external structures. Side loads can damage the boom and destabilise the machine, so the task falls outside the licensed scope.

Question 24Boom-type elevating work platform scope of work and boom length determination

An operator holds a WP licence but is asked to operate a machine whose boom length is later found to be 10.5 metres. What does this mean for the task?

  1. The operator is unlicensed for that machine and must stop
  2. The machine is below the licensing threshold, so the licence is not legally required for it Correct answer.
  3. The machine must be reclassified as a crane
  4. The operator must obtain a second licence class

Explanation

The WP licence applies at a boom length of 11 metres or more. A machine of 10.5 metres sits below that threshold, so holding the licence is not a legal prerequisite for operating it, although other training duties still apply.

Question 25Boom-type elevating work platform scope of work and boom length determination

Which combination best describes the scope of work of a licensed boom-type EWP operator?

  1. Rigging loads and directing crane movements
  2. Operating the platform within its rated capacity and positioning it for tasks at height Correct answer.
  3. Inspecting and repairing hydraulic components
  4. Designing the lift plan and certifying the machine's structure

Explanation

The operator's scope covers safe operation and positioning of the platform within its rated limits. Lift planning, structural certification, rigging and hydraulic repair each belong to other defined competencies.

Question 26Boom-type elevating work platform scope of work and boom length determination

Under the WP licence class, which machines fall within scope?

  1. Truck-mounted crane borers used for lifting personnel
  2. Order-picking forklifts operating in aisles
  3. Scissor lifts with a platform height under 11 metres
  4. Boom-type elevating work platforms with a boom length exceeding 11 metres Correct answer.

Explanation

The WP class covers boom-type elevating work platforms whose boom length exceeds 11 metres. Scissor lifts, order pickers and crane borers are regulated under different licence classes or not licensed at all. The boom length figure is the defining threshold, not platform height or working height.

Question 27Boom-type elevating work platform scope of work and boom length determination

Which measurement determines whether a machine requires a WP licence?

  1. Boom length as specified by the manufacturer Correct answer.
  2. Working height measured to the operator's hands
  3. Overall stowed height of the machine
  4. Platform height at full elevation

Explanation

The WP licence threshold is set by boom length, which is the manufacturer's declared boom measurement for that model. Platform height and working height are different figures and do not decide the licence class. Operators must confirm the boom length from the machine's documentation rather than estimating.

Question 28Boom-type elevating work platform scope of work and boom length determination

A boom platform is rated with a maximum boom length of 11 metres exactly. How is this machine classified for licensing purposes?

  1. It requires no licence because the machine is small
  2. It requires a WP licence because the threshold is 11 metres or more
  3. It falls outside WP because it does not exceed 11 metres Correct answer.
  4. It requires a WP licence only if the platform exceeds 11 metres in height

Explanation

The WP threshold is expressed as a boom length exceeding 11 metres, so a machine of exactly 11 metres does not meet it. Operators should verify the manufacturer's stated boom length rather than rounding up. Where doubt exists, the regulator or manufacturer should be consulted before work proceeds.

Question 29Boom-type elevating work platform scope of work and boom length determination

What is the most reliable source of a machine's declared boom length?

  1. A measurement taken with a tape from the basket
  2. The site supervisor's estimate
  3. The operator's recollection of a similar model
  4. The manufacturer's data plate or specification documentation Correct answer.

Explanation

Boom length is a manufacturer-declared figure recorded on the data plate and in the specification documentation. Physical tape measurement cannot capture the true extended boom length of an articulated or telescopic machine. Estimates and recollection are unreliable and should never determine licence requirements.

Question 30Boom-type elevating work platform scope of work and boom length determination

Which task is outside the scope of work of a licensed boom-type EWP operator?

  1. Using the platform to reach and inspect roof fixings
  2. Positioning the basket beside a wall for painting
  3. Rigging a load to the boom to lift it onto a scaffold Correct answer.
  4. Elevating a worker to install signage on a building facade

Explanation

A boom-type EWP is designed to elevate personnel with tools and materials, not to act as a crane. Attaching loads to the boom for lifting is outside the machine's design purpose and outside the operator's scope. Signage work, inspection and painting from the basket are ordinary uses of the platform.

Question 31Boom-type elevating work platform scope of work and boom length determination

An operator is asked to use the boom platform to tow a small trailer across the site. What is the correct response?

  1. Agree, provided the trailer is light and the ground is flat
  2. Agree, provided the machine is in the stowed position
  3. Agree, provided a spotter walks behind the trailer
  4. Refuse, because towing is not a function of a boom-type EWP Correct answer.

Explanation

Boom-type elevating work platforms are designed to elevate personnel, not to tow or recover other equipment. Towing attachments and loads can damage the chassis and create stability hazards. The task falls outside the machine's purpose and outside the operator's scope of work.

Question 32Boom-type elevating work platform scope of work and boom length determination

What does the term 'boom length' describe on a boom-type elevating work platform?

  1. The distance from the rear axle to the front of the basket
  2. The length of the boom structure as declared by the manufacturer Correct answer.
  3. The vertical height from the ground to the platform floor
  4. The horizontal distance from the chassis to the basket at full outreach

Explanation

Boom length is the manufacturer's declared measurement of the boom structure itself. It is distinct from platform height, working height and outreach, which describe positions reached rather than the boom's own dimension. Licence class is determined by this declared boom length.

Question 33Boom-type elevating work platform scope of work and boom length determination

Why must an operator confirm the boom length before accepting a machine for work?

  1. To calculate the fuel consumption for the shift
  2. To confirm the machine matches the licence class held and the task requirements Correct answer.
  3. To determine the tyre pressure required
  4. To decide the colour coding for the site tag

Explanation

Confirming boom length establishes whether the machine falls within the operator's licence class and whether it can reach the required work area. Operating a machine outside the licensed class is an offence and creates serious risk. Fuel, tagging and tyre pressures are unrelated to this check.

Question 34Boom-type elevating work platform scope of work and boom length determination

A boom platform has a declared boom length of 14 metres and a maximum platform height of 12 metres. Which figure confirms the machine is in the WP class?

  1. The difference between the two figures
  2. The sum of the two figures
  3. The 12 metre platform height
  4. The 14 metre boom length Correct answer.

Explanation

Licence classification depends solely on boom length, so the 14 metre figure confirms the machine exceeds the 11 metre threshold. Platform height describes reach but does not determine the licence class. Arithmetic combinations of the two figures have no licensing meaning.

Question 35Boom-type elevating work platform scope of work and boom length determination

An operator holds a WP licence and is offered a machine with a boom length of 10 metres. What is the correct action?

  1. Operate it only after notifying the regulator
  2. Operate it, because any boom platform is covered by the WP licence
  3. Decline unless trained and authorised for that machine, as it falls outside the WP class Correct answer.
  4. Operate it only for tasks under two hours

Explanation

A machine with a boom length of 10 metres does not exceed the 11 metre threshold, so it is not covered by the WP class. The operator must not assume the licence extends to it and should seek clarification on the applicable requirements. Operating without the correct authorisation remains unsafe regardless of task duration.

Question 36Boom-type elevating work platform scope of work and boom length determination

Which document should an operator consult to confirm both the boom length and the machine's rated capacity?

  1. The toolbox talk attendance sheet
  2. The manufacturer's operation manual and load chart Correct answer.
  3. The delivery docket from the hire company
  4. The site induction booklet

Explanation

The manufacturer's manual and load chart contain the declared boom length, capacity ratings and operating limits for the specific model. These are the authoritative figures for planning lifts and confirming licence class. Site paperwork and delivery documents do not carry engineering data.

Question 37Boom-type elevating work platform scope of work and boom length determination

Why does increasing boom extension generally reduce the capacity available at the basket?

  1. The machine's tyres flatten under extension
  2. The basket becomes heavier as it moves outward
  3. The hydraulic pump loses pressure as the boom extends
  4. The load moment about the chassis increases with reach Correct answer.

Explanation

Capacity is limited by the load moment, which is the product of load and horizontal distance from the tipping line. Extending the boom increases that distance and therefore the moment for the same load. The load chart reduces allowable basket load accordingly to preserve stability.

Question 38Boom-type elevating work platform scope of work and boom length determination

A machine's load chart shows a capacity of 230 kilograms at 6 metres outreach and 120 kilograms at 12 metres outreach. A task needs 10 metres outreach with a 150 kilogram basket load. What does this indicate?

  1. The capacity at 10 metres must be checked against the chart before proceeding Correct answer.
  2. The task is acceptable because 150 kilograms is below 230 kilograms
  3. The task is acceptable if the boom is retracted slightly during the lift
  4. The task requires interpolation, so the operator may proceed at their discretion

Explanation

Capacity falls as outreach increases, so the figure at 10 metres lies between the two charted values and must be read from the chart. Assuming the 6 metre rating applies at 10 metres would overload the machine. The operator must confirm the specific rating for the planned configuration before lifting.

Question 39Boom-type elevating work platform scope of work and boom length determination

Which factor most directly determines whether a boom platform can safely travel over a particular section of ground?

  1. The ground bearing pressure and slope relative to the manufacturer's limits Correct answer.
  2. The number of workers standing nearby
  3. The age of the machine's tyres
  4. The colour of the ground marking paint

Explanation

Ground conditions must be assessed against the manufacturer's limits for bearing pressure, slope and surface type. Soft or uncompacted ground can cause the machine to sink or overturn. Markings, bystanders and tyre age do not establish whether the ground can support the machine.

Question 40Boom-type elevating work platform scope of work and boom length determination

An operator needs to reach a work point, but the required outreach exceeds the machine's rated envelope at that height. What is the correct course of action?

  1. Extend the boom slowly to avoid overloading
  2. Position the machine closer or select a machine with sufficient reach Correct answer.
  3. Reduce the basket load and proceed to full outreach
  4. Add counterweight to the chassis

Explanation

The rated envelope defines the combinations of height and outreach the machine can safely achieve. If the work point lies outside it, the machine must be repositioned or a larger machine selected. Operating beyond the envelope, slowing movements or altering counterweight does not make the lift safe.

Question 41Boom-type elevating work platform scope of work and boom length determination

What is the primary purpose of the platform's load chart?

  1. To show the machine's transport dimensions
  2. To record maintenance intervals for the boom
  3. To define safe combinations of load, height and outreach for the machine Correct answer.
  4. To list the names of authorised operators

Explanation

The load chart specifies the maximum allowable load at given heights and outreaches, preserving stability and structural integrity. Operators must read it for each planned configuration. Maintenance schedules, operator lists and transport dimensions appear in other documents.

Question 42Boom-type elevating work platform scope of work and boom length determination

A boom platform is to be used near an excavation edge. Which check is most important before setting up?

  1. Ensuring the operator has a high-visibility vest
  2. Checking that the excavation is fenced with tape
  3. Confirming the spoil pile is neatly shaped
  4. Verifying the ground near the edge can support the machine's outrigger or wheel loads Correct answer.

Explanation

Ground near an excavation edge may be undermined and unable to carry the machine's concentrated loads. The bearing capacity and setback distance must be confirmed before setup. Fencing, spoil shaping and PPE are relevant site controls but do not establish structural ground capacity.

Question 43Boom-type elevating work platform scope of work and boom length determination

What does the term 'working height' add to the platform height figure?

  1. The height of any tools stored in the basket
  2. The height of the chassis above the ground
  3. The distance from the ground to the boom pivot
  4. Approximately two metres representing a person's reach above the platform Correct answer.

Explanation

Working height is commonly taken as platform height plus about two metres to represent a worker's reach. It is a planning figure and is not the licensing measure, which is boom length. Confusing working height with boom length can lead to incorrect assumptions about licence requirements.

Question 44Boom-type elevating work platform scope of work and boom length determination

Which statement best describes the relationship between licence class and machine capability?

  1. The licence class confirms the operator may operate machines within that class, subject to task-specific competency Correct answer.
  2. The licence class authorises the operator to supervise all high risk work
  3. The licence class guarantees the machine is fit for any task
  4. The licence class certifies the operator to modify the machine's load chart

Explanation

A licence confirms the holder may operate machines within that class, but competency for the specific machine and task is still required. The licence does not authorise modifying load charts or supervising unrelated high risk work. Fitness of the machine is established through inspection and maintenance, not the licence.

Question 45Boom-type elevating work platform scope of work and boom length determination

An operator is planning work at height and must decide between two machines with boom lengths of 12 metres and 16 metres. What is the key licensing consideration?

  1. The 12 metre machine requires a different licence class
  2. Only the 16 metre machine requires a WP licence
  3. Neither machine is covered by the WP class
  4. Both machines fall within the WP class because both exceed 11 metres Correct answer.

Explanation

Both boom lengths exceed the 11 metre threshold, so both machines fall within the WP class. The choice between them then depends on reach, capacity and site conditions rather than licensing. Operators should still confirm the declared boom length from each machine's documentation.

Question 46Boom-type elevating work platform scope of work and boom length determination

Which practice best ensures an operator stays within the licensed scope when machines are swapped during a project?

  1. Asking a workmate who operated the machine previously
  2. Checking each machine's declared boom length against the licence held before use Correct answer.
  3. Relying on the hire company to advise the licence class
  4. Assuming all boom platforms on site are identical

Explanation

Each machine must be individually verified against the licence class before use, because boom lengths vary between models. Relying on hire companies, assumptions or workmate reports does not discharge the operator's duty. The declared boom length on the data plate or documentation is the authoritative check.

Question 47Boom-type elevating work platform scope of work and boom length determination

Why is it insufficient to rely on the platform height alone when determining licence requirements?

  1. Platform height is not the measure used to define the WP licence class Correct answer.
  2. Platform height varies with the weather during the shift
  3. Platform height is only recorded for scissor lifts
  4. Platform height is always greater than boom length

Explanation

The WP licence class is defined by boom length, so platform height cannot establish whether a licence is required. A machine with a modest platform height may still have a boom length above the threshold. Operators must therefore check the declared boom length rather than the height reached.

Question 48Boom-type elevating work platform scope of work and boom length determination

A supervisor asks the operator to use the boom platform to support a suspended scaffold plank while a worker stands on it. What is the correct response?

  1. Agree, provided the machine's capacity is not exceeded
  2. Agree, provided the platform is not elevated above five metres
  3. Refuse, because using the platform to support another work surface is outside its designed purpose Correct answer.
  4. Agree, provided the worker wears a harness

Explanation

The platform is designed to carry persons and materials within the basket, not to support other work surfaces. Using the boom to hold a scaffold plank creates uncontrolled loads and fall hazards. Capacity, height and harness use do not make such an arrangement acceptable.

Question 49Boom-type elevating work platform scope of work and boom length determination

Which combination best reflects the operator's responsibilities regarding boom length and scope of work?

  1. Rely on the site register and operate any machine listed there
  2. Operate any boom platform provided the operator holds a current WP licence
  3. Confirm the boom length, operate only within the licensed class, and use the machine only for its designed purpose Correct answer.
  4. Confirm the boom length and then operate the machine for any task requested by the supervisor

Explanation

The operator must verify boom length, stay within the licensed class and use the machine only for its designed purpose. A supervisor's request or a site register does not override these duties. Holding a WP licence does not extend authority to machines outside the class.

Question 50Boom-type elevating work platform scope of work and boom length determination

An operator measures the boom of a telescopic machine with a tape and obtains 10.8 metres, while the data plate states 12.5 metres. Which figure governs licensing?

  1. The average of the two figures
  2. The data plate figure, because it is the manufacturer's declared boom length Correct answer.
  3. The tape measurement, because it reflects the actual machine
  4. Whichever figure the supervisor prefers

Explanation

The manufacturer's declared boom length on the data plate governs licensing, because tape measurement cannot capture the true extended geometry of the boom. The machine therefore exceeds the 11 metre threshold and falls within the WP class. Discrepancies should be reported and resolved before use.
