- Intermediate scaffolder licence
- A high-risk work licence class authorising the holder to erect, alter, and dismantle the scaffold types specified in the national competency standard for that class, subject to any conditions.
- Licence condition
- A restriction or requirement attached to a licence, such as the scaffold types permitted or supervision required, which the holder must comply with at all times.
- PCBU duty
- The primary duty of a person conducting a business or undertaking to ensure health and safety so far as reasonably practicable, including safe scaffolding systems, training, and supervision.
- Scaffold plan
- A documented description of the scaffold type, dimensions, load class, foundation, ties, and access, prepared before erection and used to control the work.
- Ground bearing check
- Verification that the soil or surface under base plates can support the scaffold loads without excessive settlement, often requiring soleboards or engineered support.
- Service clearance
- The safe distance maintained between a scaffold and overhead or underground services such as powerlines, confirmed with the asset owner before work begins.
- SWMS
- A safe work method statement setting out the high-risk construction work, the hazards, the controls, and the review arrangements, required before work starts.
- Plumb tolerance
- The permitted deviation of a standard from vertical, specified by the manufacturer or design, commonly checked with a spirit level at each lift.
- Tie installation
- The fixing of scaffold ties to the structure at the spacing set by the design, installed progressively as erection proceeds to maintain stability.
- Dismantling sequence
- Removal of scaffold components in reverse order of erection, working from the top down, with ties removed only as the work descends.
- Duty rating
- The rated load a scaffold platform may carry, commonly light, medium, or heavy, set by the design and displayed at the access point.
- Dead load
- The permanent weight of scaffold components such as standards, ledgers, transoms, planks, and guardrails, which the design must support.
- Live load
- The variable load on a platform from workers, tools, and materials, which must not exceed the duty rating of the scaffold.
- Wind load
- The force on a scaffold from wind, affected by location, height, terrain, and permeability, used by the designer to set tie spacing and restrictions.
- Soleboard
- A timber or engineered pad under a base plate that spreads the standard load over a larger area to keep ground pressure within capacity.
- Scaffold tag
- A label at the access point recording the scaffold ID, duty rating, inspection date, inspector, and status such as safe, incomplete, or do not use.
- Coupler torque
- The tightening force applied to a scaffold coupler, checked with a torque wrench to the value specified by the manufacturer or design.
- Post-event inspection
- An inspection by a competent person after high wind, impact, or alteration, required before the scaffold is used again regardless of the normal inspection cycle.
- Suspension trauma
- A medical emergency that can develop within minutes when a person is suspended in a harness, requiring prompt rescue and monitoring.
- Rescue plan
- A documented, practised, and resourced procedure for recovering a fallen or suspended worker from a scaffold without delay.
- Competent person
- A person with the training, qualification, and experience to perform the specific scaffold task safely, verified through records and observation.
- Toolbox talk
- A short pre-work briefing communicating the scaffold plan, hazards, controls, and any changes to the crew before work begins.
- Wind speed limit
- The maximum wind speed at which a scaffold may be erected, used, or dismantled, set by the manufacturer or design, above which work stops.
- Overhead protection
- A fan, gantry, or catch platform installed where a scaffold adjoins a public way to protect people below from falling objects.
- Scaffold register
- A record of each scaffold's ID, design reference, duty rating, erection date, and inspection history, kept for compliance and audit.
- Hierarchy of control
- The order of risk controls from elimination and substitution through engineering and administrative controls to PPE as the last resort.
- Dynamic risk assessment
- A check at the start of each shift or task that identifies changes in conditions and confirms controls remain effective before work continues.
- Component inspection
- Pre-use and periodic checking of scaffold parts for damage or wear, with defective items tagged and removed from service.
- Fall arrest system
- Equipment that stops a fall, requiring a rated anchor, suitable lanyard, trained user, inspection, and a rescue plan.
- Notifiable incident
- A death, serious injury, or dangerous incident such as scaffold collapse that must be reported to the regulator immediately.
- Height-to-base ratio
- The relationship between a scaffold's height and its base dimensions, which governs stability and may require outriggers or a wider base.
- Induction
- Site-specific training covering rules, scaffold access, emergency procedures, and defect reporting, completed before a worker starts on site.
