HSC Construction (VET) key terms

A legal term for the business or organisation that runs work activities. A PCBU must ensure the health and safety of workers and others affected by the work, so far as reasonably practicable.

The legal and moral obligation everyone on a construction site has to act carefully so their actions do not harm themselves or others. Workers must follow safety instructions and report hazards.

A test used in work health and safety law. It asks whether the cost, time and difficulty of controlling a risk are far greater than the risk itself, after considering what is known.

A ranked list of ways to manage risk, from most to least effective: eliminate the hazard, substitute it, use engineering controls, use administrative controls, then rely on personal protective equipment.

Anything with the potential to cause injury, illness or damage, such as an unguarded saw, loose material at height, exposed wiring or slippery ground. Hazards are identified before work starts.

The chance that a hazard will actually cause harm, combined with how serious that harm could be. Risk is assessed by considering likelihood and consequence together.

The action taken to remove or reduce a risk, such as fitting guards, improving ventilation, changing work methods or issuing protective equipment. Controls are reviewed to check they still work.

Clothing and gear worn to reduce exposure to hazards, such as hard hat, safety boots, eye protection, gloves, hearing protection and high-visibility clothing. PPE is the last line of defence.

A standard document supplied with a hazardous chemical that lists its hazards, safe handling, storage, first aid and emergency procedures. Workers must be able to access the SDS for chemicals on site.

A chemical or material that can harm health, such as solvents, adhesives, lead dust or silica dust. It requires labelling, an SDS, safe storage and controls to limit exposure.

Fine dust released when cutting, grinding or drilling concrete, stone or brick products containing crystalline silica. Breathing it can cause serious lung disease, so water suppression and respiratory protection are used.

A written document that sets out high-risk construction work, the hazards involved, the control measures and how they will be applied and monitored. Workers are consulted and sign on to it.

Work defined by work health and safety regulations as needing a SWMS, such as work at height over two metres, demolition, excavation, and work near energised electrical installations or asbestos.

A short, informal safety briefing held with the work crew before or during a shift. It covers current hazards, changes to the work, lessons from incidents and any questions workers raise.

A record made when a worker identifies a hazard that they cannot fix themselves. It tells supervisors what the hazard is, where it is and what harm it could cause, so action can be taken.

A naturally occurring fibrous mineral once used widely in building products. Disturbing it releases fibres that cause serious disease, so it must be identified and removed only by licensed workers.

Any work where a person could fall from one level to another and be injured, including work on ladders, scaffolds, roofs and edges. Fall prevention is required before work begins.

A temporary structure of standards, ledgers, transoms and planks that gives workers a safe platform at height. Only licensed or competent people erect, alter and dismantle it, and it is inspected regularly.

A person who has the training, qualifications, experience and knowledge to safely carry out a particular task, such as inspecting scaffolding or testing electrical equipment.

The procedure for making equipment or services safe before work by switching off, disconnecting, locking and tagging energy sources so they cannot be re-energised accidentally.

The compulsory introduction given to everyone entering a construction site. It covers site rules, hazards, emergency procedures, amenities, first aid and reporting requirements before work starts.

The documented procedure for leaving the site safely in an emergency. It shows assembly points, alarm signals, exit routes and the roles of wardens and first aiders.

The ratio between a drawing measurement and the real size of the building, such as 1:100. It lets tradespeople calculate actual lengths and check dimensions from a scaled plan.

A detailed technical drawing used on site to build the work. It shows plans, elevations, sections, dimensions, materials and construction details needed to complete the job accurately.

A written document that describes the quality, materials, standards and workmanship required for a project. It works with the drawings to define what must be built and how.

A drawing that shows the outside face of a building or wall as seen straight on, without perspective. It shows heights, openings, cladding and roof lines.

A drawing that shows a cut-through view of a building or component, revealing internal construction such as floor build-up, framing, insulation and roof structure.

A line on a drawing with arrows or ticks at each end and a number showing the measurement between two points. Dimensions are read in millimetres unless noted otherwise.

The checks and processes used to make sure work meets the specification, standards and client requirements. It includes inspecting materials, checking dimensions and recording results.

The acceptable amount by which a measurement or finish may vary from the stated requirement. Work outside tolerance is rejected or corrected before it is accepted.

A fault or imperfection in work or materials that does not meet the specification or expected standard. Defects must be reported and rectified before handover.

A tool powered only by the user's own effort, such as a hammer, hand saw, chisel, level or tape measure. Hand tools need regular inspection and correct technique.

A tool driven by electricity, battery, compressed air or fuel, such as a circular saw, nail gun or grinder. Power tools require guards, inspection and safe lead and battery handling.

The routine care that keeps tools safe and accurate, including cleaning, sharpening blades, checking leads and guards, and tagging out faulty equipment. Poorly maintained tools cause injuries and inaccurate work.

The process of marking the position, levels and dimensions of a structure or component on site before construction. Accurate setting out ensures walls, footings and frames are square and correctly placed.

A fixed reference point or level from which heights and positions are measured on a site or drawing. All related measurements are taken from the same datum to keep work consistent.

Checking that surfaces and corners are true: level means horizontal, plumb means vertical, and square means corners form a right angle. These checks keep frames and finishes accurate.

Meeting present needs without compromising resources and the environment for the future. On site this means reducing waste, saving energy and water, and choosing materials wisely.

Planning and controlling how waste is reduced, separated, stored and disposed of on site. Good practice sorts materials for reuse and recycling and keeps hazardous waste separate.

Processing used materials such as timber, metals, concrete and packaging so they can be made into new products instead of going to landfill. It requires correct separation on site.

Measures that stop soil and muddy water leaving a site and polluting drains or waterways. Examples include silt fences, sediment basins and stabilised entry points.

An unplanned event that harms or could harm the environment, such as a chemical spill, fuel leak or sediment discharge. It must be contained and reported immediately.

A material that can be replenished or regrown within a reasonable time, such as plantation timber, bamboo or wool. Choosing renewable materials reduces long-term environmental impact.

Using less energy to achieve the same result, through better design, insulation, efficient equipment and reduced waste. It lowers costs and greenhouse gas emissions.

The exchange of information on a construction site through instructions, drawings, signs, radios and written records. Clear communication prevents errors, rework and safety incidents.

A direction telling a worker what task to do and how to do it, given verbally or in writing by a supervisor. Workers should confirm they understand and ask questions if unclear.

Working cooperatively with others to complete tasks safely and on time, sharing information, helping colleagues and respecting each person's role on site.

The process of addressing disagreements between workers calmly and respectfully so work continues safely. It usually involves listening, clarifying the issue and agreeing on a solution.
