SWMS & WHS Glossary — Every Safety Term Explained

Administrative Controls — the fourth level of the hierarchy of controls under WHS Regulation 2025. Administrative controls use procedures, training, supervision, signage, and work scheduling to reduce the risk of harm without removing the underlying hazard. Examples include SWMS themselves, toolbox talks, permit-to-work systems, job rotation, exclusion zone signage, and training programs. Administrative controls rely on human behaviour and are therefore less reliable than elimination, substitution, isolation, or engineering controls, which is why the hierarchy places them near the bottom.

Asbestos — a naturally occurring fibrous silicate mineral used widely in Australian building materials before 2003. Any work involving the disturbance of asbestos-containing materials is HRCW under Schedule 1 of WHS Regulation 2025 and requires a SWMS. Asbestos management is governed by Part 8.2 of the Regulation and by the Code of Practice How to Manage and Control Asbestos in the Workplace. Contractors performing asbestos work need specific training (Class A for friable asbestos, Class B for non-friable) and must use air monitoring, personal monitoring, and decontamination procedures. Asbestos-related diseases have latency periods of 20 to 40 years, which is one of the strongest reasons to retain SWMS and exposure records permanently.

Asbestos Management Plan — a documented plan required under WHS Regulation 2025 Part 8.2 for any workplace where asbestos or asbestos-containing material has been identified. The plan must describe the location and condition of the asbestos, the arrangements for managing disturbance risk, the air monitoring schedule, the response to incidental discovery, and the removal arrangements when decommissioning. The plan must be updated when conditions change and reviewed at least every 5 years.

AS/NZS Standards — Australian and New Zealand Standards published by Standards Australia. Standards are technical documents that describe best practice for specific activities and equipment. They are not law in themselves, but regulators and courts use them as the benchmark for what is reasonably practicable under the duty of care. Key standards for construction SWMS include AS/NZS 1891 (industrial fall arrest systems), AS/NZS 2865 (safe working in a confined space), AS/NZS 4024 (safety of machinery), AS/NZS 3012 (electrical installations on construction and demolition sites), and AS/NZS 4576 (guidelines for scaffolding). A SWMS that references the relevant standards shows the regulator that the contractor has considered the authoritative technical guidance, while a SWMS that omits standards references is usually treated as less credible.

AS 1674.1 — the Australian Standard for safety in welding and allied processes, specifically covering fire precautions during hot work. The standard specifies the 11-metre exclusion zone for combustible materials, the fire watch requirements, and the controls for hot work in areas with fire risk. Hot work permits routinely reference AS 1674.1 as the technical basis for the permit conditions.

Competent Person — a person who has acquired through training, qualification, or experience the knowledge and skills to carry out a specific task. The WHS Regulation requires competent persons for several specific activities, including asbestos removal supervision, scaffolding inspection above 4 metres, atmospheric testing in confined spaces, rigging and dogging above specified loads, crane operation, and electrical work on live installations. The test of competency is activity-specific, not general, and a person may be competent for some tasks within their trade but not for others.

Confined Space — defined in WHS Regulation 2025 Regulation 5 as an enclosed or partially enclosed space that is not designed or intended to be occupied by a person, has a limited means of entry or exit, and is at atmospheric pressure. Confined space entry is HRCW under Schedule 1 and requires a SWMS. The work is also governed by Part 4.3 of the Regulation and by AS/NZS 2865-2009. Typical confined spaces on construction sites include tanks, vessels, pits, manholes, ducts, silos, sewers, and enclosed plant rooms during maintenance or commissioning. Atmospheric hazards (oxygen deficiency, flammable gases, toxic gases) are the main fatal hazard in confined space work.

Control Measure — any action taken to eliminate or minimise a risk under the hierarchy of controls. Control measures are the core content of a SWMS under WHS Regulation 2025 section 299, which requires the document to describe the measures to be implemented to control the risks associated with the HRCW. Effective SWMS list multiple controls per hazard, arranged in descending order of the hierarchy, so that the regulator can see the PCBU has considered higher-order controls before falling back on PPE.

Code of Practice — published guidance from Safe Work Australia or the relevant state regulator that explains how to meet the requirements of the WHS Act and Regulation. Codes of Practice are admissible in court as evidence of what is reasonably practicable, and a PCBU who follows the Code is presumed to have met the duty of care unless the circumstances require something different. Key codes for construction SWMS include How to Manage Work Health and Safety Risks, Construction Work, Preventing Falls in Housing Construction, How to Manage and Control Asbestos in the Workplace, and Safe Design of Structures. Victoria uses WorkSafe Victoria Compliance Codes rather than Safe Work Australia Codes of Practice, but the function is equivalent.

CPCCWHS1001 — the current national unit of competency for the General Construction Induction Training program, commonly called the White Card. Every worker entering a construction site must hold a current White Card under this unit. The older unit CPCCOHS1001A has been superseded and should not appear in any SWMS or induction record produced in 2025 or later. A SWMS that references the superseded unit signals that the contractor is working from out-of-date source material and will often be returned for revision.

BYDA (Before You Dig Australia, formerly Dial Before You Dig) — a free national referral service that provides plans showing the location of underground infrastructure (gas, water, electricity, telecommunications, sewer, and fibre) before excavation. Contractors obtain a reference number before any ground disturbance and should document it in the SWMS for excavation work. BYDA plans have a standard positional tolerance and do not guarantee completeness, so the contractor must still visually locate services in the tolerance zone using hand excavation or non-destructive digging. The service is accessible by phone on 1100 or online at byda.com.au.

Demolition — the destruction, dismantling, or removal of a structure or a significant part of a structure. Demolition of an element of a structure that is load-bearing or otherwise related to the physical integrity of the structure is HRCW under Schedule 1 of WHS Regulation 2025 and requires a SWMS. Demolition work is also governed by AS 2601 Demolition of structures and typically requires a demolition licence under state building legislation. Pre-demolition asbestos surveys are mandatory for pre-2003 buildings under WHS Regulation Part 8.2, and the asbestos register must be made available to all workers on site.

Duty of Care — the legal obligation under WHS Act 2011 section 19 to ensure, so far as is reasonably practicable, the health and safety of workers and others who may be affected by the work. The duty applies to every PCBU and cannot be delegated or contracted out. Discharging the duty requires the PCBU to identify hazards, assess risks, implement control measures, provide information and training, consult with workers, and monitor effectiveness. A SWMS is one of the practical vehicles for demonstrating that the duty has been discharged for HRCW activities. The duty is not absolute — it requires what is reasonably practicable in the circumstances, balancing the risk against the cost and difficulty of eliminating or minimising it.

Dangerous Incident — defined in WHS Act section 37 as an incident that exposes a person to a serious risk to their health or safety, even if no one was actually injured. Examples include uncontrolled escape of substances, fire, explosion, electric shock, fall of objects from height that could have caused injury, structural collapse, excavation collapse, and gas or water inrush. Dangerous incidents are notifiable under section 35 and must be reported to the regulator immediately, regardless of whether any person was harmed. The SWMS review obligation under Regulation 300 is triggered by dangerous incidents as well as injuries.

Elimination — the first and most effective level of the hierarchy of controls. Elimination removes the hazard entirely from the workplace, so the risk is eliminated rather than merely reduced. Examples include designing out work at height by assembling components at ground level, prefabricating structural elements off-site to eliminate on-site hazards, and substituting a process that generates no hazardous emissions. The WHS Regulation requires elimination to be considered first for every hazard, and if elimination is not reasonably practicable, the next level of the hierarchy must be applied. A SWMS that lists only PPE for a fall hazard, without considering elimination or higher-order controls, is typically criticised by regulators.

Engineering Controls — the third level of the hierarchy of controls. Engineering controls use physical modifications to plant, equipment, or work processes to reduce the risk without requiring behaviour change from workers. Examples include guardrails as the primary fall prevention control, local exhaust ventilation to capture welding fumes at source, trench shoring to prevent excavation collapse, residual current devices on electrical circuits, and machine guarding to prevent contact with moving parts. Engineering controls are more reliable than administrative controls and PPE because they do not depend on workers remembering or complying with procedures.

EWP (Elevating Work Platform) — a mechanical device used to provide temporary access to inaccessible areas, usually at height. Includes boom lifts, scissor lifts, and truck-mounted cherry pickers. Operation of an EWP with a boom length greater than 11 metres requires a high-risk work licence (WP class). Using an EWP does not automatically eliminate the HRCW trigger for fall hazards above 2 metres — a SWMS is still required, and the controls address the specific hazards of EWP operation including overhead powerline proximity, ground condition suitability, wind loading, and fall restraint within the basket.

Excavation — any activity that involves the removal of earth, rock, or other material to form a cavity, trench, or shaft. Excavation to a depth greater than 1.5 metres is HRCW under Schedule 1 of WHS Regulation 2025 and requires a SWMS. Excavation work is also governed by the shoring, battering, and benching requirements under Part 6.3, and by AS 2187 for the specific technical aspects. Underground service strikes are the dominant fatal hazard in excavation work, which is why BYDA plans and visual location of services are mandatory preparation steps.

Exclusion Zone — a designated area where access is restricted to prevent exposure to a hazard. Exclusion zones are administrative controls under the hierarchy, and they must be clearly marked with physical barriers, signage, or both. Common exclusion zones on construction sites include crane swing radii, the area below overhead work, the perimeter of excavations, the area around energised electrical equipment, and the fall zones below working at heights. Exclusion zones must be enforced through supervision, and a zone that is established but not monitored is not effective.

Fall Arrest — a system designed to safely stop a person who is falling from height. Includes full-body harnesses, lanyards, energy absorbers, anchor points, and fall-arrest lines. The system must comply with AS/NZS 1891 series, which covers the technical requirements for components, installation, inspection, and use. Fall arrest is a last-resort control in the hierarchy — elimination (eliminating the need to work at height) and fall prevention (passive controls like guardrails and scaffolding) should be considered first. A SWMS that relies on fall arrest as the primary control for fall hazards, without showing that higher-order controls were considered and rejected, is usually criticised by regulators.

Fall Prevention — passive or engineered controls that prevent a worker from reaching a fall exposure. Includes guardrails, scaffolding with handrails and midrails, catch platforms, safety mesh, and edge protection on roofs. Fall prevention is preferred over fall arrest under the hierarchy of controls because it does not require a fall to occur before the control engages. WHS Regulation 2025 requires fall prevention controls to be considered first where work is performed at height above 2 metres (Victoria applies its own fall prevention provisions under OHS Regulation 2017 Part 3.3).

First Aid — the immediate treatment of injured or ill workers before professional medical help arrives. PCBUs must provide first aid equipment, trained first aiders, and first aid facilities appropriate to the nature of the work and the number of workers. The Safe Work Australia Code of Practice First Aid in the Workplace provides guidance on first aid requirements for different work environments. First aid arrangements should be documented in the SWMS and the WHS Management Plan, including the location of kits, the names of trained first aiders, and the arrangements for calling emergency services.

Fragile Roof — a roof constructed of materials that will not reliably support a person's weight. Common fragile roof materials include asbestos cement sheeting, corroded steel sheeting, fibreglass skylights, and single-layer polycarbonate panels. Work on or near fragile roofs is one of the most common fatal hazard categories in Australian construction, and the SWMS must identify fragile areas and specify the controls — typically physical barricading of fragile sections, safety mesh below, and fall-arrest systems for any unavoidable traverse. AS/NZS 1891.4 and the National Code of Practice for the Prevention of Falls in General Construction apply to fragile roof work.

Hazard — anything that has the potential to cause harm — injury, illness, or damage. Hazards can be physical (fall from height, electrical contact, noise, vibration), chemical (solvent vapours, asbestos fibres, respirable crystalline silica), biological (contaminated water, mould, zoonoses), ergonomic (manual handling, repetitive motion), or psychosocial (fatigue, time pressure, bullying). A SWMS must identify the specific hazards associated with the HRCW under WHS Regulation 2025 section 299, and the hazard identification should be site-specific rather than generic.

Hierarchy of Controls — the ranked order in which control measures should be considered under WHS Regulation 2025. The hierarchy, from most effective to least effective, is elimination, substitution, isolation (or engineering), administrative, and PPE. The regulation requires risks to be eliminated so far as is reasonably practicable, and if elimination is not reasonably practicable, minimised using the remaining levels in descending order. A SWMS should document the controls in hierarchy order, showing that higher-order controls were considered before lower-order alternatives were adopted.

HRCW (High-Risk Construction Work) — the 18 categories of construction work defined in Schedule 1 of WHS Regulation 2025 that require a SWMS before work commences. The categories include work where a person could fall more than 2 metres, work on a telecommunication tower, demolition of a load-bearing structural element, disturbance of asbestos, structural alterations requiring temporary support, confined space entry, excavation deeper than 1.5 metres, tunnelling, use of explosives, work on or near pressurised gas, fuel or refrigerant lines, work on or near energised electrical installations, work in areas with contaminated or flammable atmospheres, tilt-up and precast concrete work, work adjacent to roads or traffic corridors, work around powered mobile plant, work in extremes of temperature, and work in or near water with a drowning risk.

HSR (Health and Safety Representative) — a worker elected by their work group to represent them on health and safety matters under Part 5 of the WHS Act. HSRs have specific powers including the right to inspect the workplace, be consulted on safety decisions, access documents relevant to worker health and safety, and issue provisional improvement notices (PINs) for contraventions. HSRs should be consulted in the preparation and review of SWMS, and a SWMS prepared without consulting the relevant HSR does not meet the consultation requirements under section 47 of the Act. Victoria uses the same Health and Safety Representative role under the OHS Act 2004.

Hot Work — any work that produces sparks, flames, molten material, or sufficient heat to ignite combustible material. Includes oxy-cutting, arc welding, MIG welding, TIG welding, grinding, brazing, soldering, thermal lancing, and heat-bonded waterproofing. Hot work typically requires a permit on managed sites, and the permit references AS 1674.1 for the fire safety controls. The 11-metre exclusion zone for combustible materials, the fire watch requirement for at least 30 minutes after work ceases, and the isolation of smoke detectors are the standard permit conditions.

Improvement Notice — a formal notice issued by a WHS inspector under section 191 of the WHS Act requiring a PCBU to remedy a contravention within a specified timeframe. If a SWMS is missing or inadequate, an inspector can issue an improvement notice requiring the PCBU to prepare or revise it. Failure to comply with an improvement notice is a separate offence under section 193 with its own penalty. Improvement notices are the most common enforcement action on Australian construction sites and are publicly searchable on most state regulator websites.

Prohibition Notice — a more serious notice issued under section 195 of the WHS Act directing that a specified activity cease immediately because it involves or will involve a serious risk to health or safety. Prohibition notices are used when the inspector considers the risk is too high to allow work to continue pending normal compliance action. Failure to comply with a prohibition notice is a separate offence with substantial penalties including imprisonment.

Induction (General Construction) — the mandatory training course for all workers on a construction site, delivered under the national unit of competency CPCCWHS1001. The course covers general WHS awareness, the common hazards on construction sites, and the worker's rights and responsibilities under WHS law. Successful completion results in a General Construction Induction card (the White Card) that is valid nationally and does not expire. The White Card is not a substitute for site-specific induction or SWMS briefing — it covers general awareness only.

JSA (Job Safety Analysis) — a risk assessment document that breaks a task into steps, identifies hazards at each step, and describes controls. Used for non-HRCW tasks where a SWMS is not legally required but documented risk assessment is useful for training, supervision, or principal contractor acceptance. JSAs are not legally mandated by WHS Regulation 2025, and a JSA does not substitute for a SWMS when HRCW is involved. Also called JHA (Job Hazard Analysis) in some jurisdictions, and JSEA (Job Safety and Environment Analysis) when the document also addresses environmental risks.

JSEA (Job Safety and Environment Analysis) — a JSA with an added environmental risk component. Common in mining, civil infrastructure, and oil and gas operations where environmental controls are regulated alongside worker safety. JSEAs typically follow the same breakdown structure as JSAs — activity, task, hazard, control — with additional columns for environmental hazards and controls.

LOTO (Lock Out Tag Out) — a safety procedure used to ensure that equipment is isolated from its energy sources and cannot be started up unexpectedly during maintenance or repair. Involves physically locking the energy isolation point (circuit breaker, valve, isolator) and attaching a tag identifying the person who applied the lock and the reason for the isolation. Each worker performing isolated work typically applies their own personal lock, which cannot be removed until they personally confirm completion. AS/NZS 4836 covers the electrical application of LOTO, and the procedure is an essential control for maintenance work on energised systems.

Notifiable Incident — an incident that must be reported to the WHS regulator immediately under section 35 of the WHS Act. Includes the death of a person, a serious injury or illness (as defined in section 36), and a dangerous incident (as defined in section 37). The site must be preserved until an inspector arrives or the regulator gives permission to resume work, and the SWMS must be retained for at least 2 years from the date of the incident. Notifiable incidents trigger the SWMS review obligation under Regulation 300.

PCBU (Person Conducting a Business or Undertaking) — the legal entity that owes the primary duty of care under the WHS Act. A PCBU is any person, partnership, or body corporate conducting a business or undertaking, whether alone or with others, and whether or not for profit. Sole traders are PCBUs in their own right. Companies are PCBUs as legal entities, and the officers of the company owe separate duties as officers of a PCBU. Victoria does not use the PCBU term and instead uses employer, which has similar but not identical scope under the OHS Act 2004.

PC (Principal Contractor) — the PCBU with overall management or control of a construction workplace where a principal contractor has been appointed. WHS Regulation 2025 section 309 requires a principal contractor to be appointed for any construction project with a contract price of $250,000 or more. The principal contractor has specific duties including obtaining SWMS from subcontractors, ensuring compliance with SWMS on site, preparing a WHS Management Plan, and coordinating activities between subcontractors.

PPE (Personal Protective Equipment) — the last level of the hierarchy of controls. Includes hard hats, safety footwear, high-visibility clothing, gloves, eye protection, hearing protection, respiratory protection, and fall-arrest harnesses. PPE does not eliminate the hazard — it provides a barrier between the worker and the hazard, and is dependent on correct selection, fitting, wearing, and maintenance. The WHS Regulation requires PPE to be considered only after elimination and higher-order controls have been assessed, and a SWMS that lists PPE as the only control for a hazard is typically criticised.

Permit to Work — a formal written authorisation issued before specific high-risk activities can commence in a controlled area. Common permit types include hot work permits, confined space entry permits, excavation permits, electrical isolation permits, and roof access permits. Permits are not directly mandated by WHS Regulation 2025 but are standard on managed construction, mining, oil and gas, and major hazard facility sites. The permit authorises the activity on a specific day at a specific location, while the SWMS covers the method and controls for the full duration of the work.

Risk Matrix — a grid used to assess risk by combining the likelihood of an event occurring with the severity of its consequences. A 5x5 matrix uses 5 levels of likelihood (rare, unlikely, possible, likely, almost certain) and 5 levels of consequence (insignificant, minor, moderate, major, catastrophic) to produce risk ratings from low to extreme. Best practice is to apply the matrix twice per hazard — once to calculate the inherent risk before controls, and once to calculate the residual risk after controls. The gap between the two ratings shows the effectiveness of the control measures.

SWMS (Safe Work Method Statement) — a legally required safety document for high-risk construction work under WHS Regulation 2025 section 299. Must identify the HRCW, specify the hazards and risks, describe the control measures, and describe how the controls will be implemented, monitored, and reviewed. Must be prepared before HRCW commences, must be accessible to workers, and must be reviewed when conditions change or after incidents. The SWMS is the central document in Australian construction safety management and is the primary focus of this guide library.

Silica (Respirable Crystalline Silica) — the fine dust produced when silica-containing materials are cut, ground, or drilled. Exposure to respirable crystalline silica causes silicosis, lung cancer, and other serious diseases. The engineered stone ban that took effect on 1 July 2024 across every Australian jurisdiction reflects the scale of the silicosis problem. NSW introduced mandatory silica awareness training for construction workers in September 2024, and other jurisdictions are following. SWMS for silica-producing work must address wet cutting, local exhaust ventilation, respiratory protection, and air monitoring.

Toolbox Talk — a short, informal safety meeting on a specific topic, typically lasting 10 to 15 minutes and held on site at the start of a shift or during a break. Different from a pre-start meeting, which covers the day's work activities — a toolbox talk focuses on a specific safety issue such as a recent incident, a new procedure, a seasonal hazard, or a regulatory change. Toolbox talks are not directly mandated by WHS law but are widely used as a consultation and training vehicle, and the records are often reviewed during audits.

Pre-Start Meeting — the daily safety briefing held before work begins on a construction site. Covers the day's activities, the hazards, the SWMS in effect, the weather and plant checks, the exclusion zones, and the emergency arrangements. Pre-start meetings are not directly mandated by WHS law but satisfy the consultation duty under section 47 of the Act and the SWMS awareness requirement under Regulation 299. Five to ten minutes is the target duration, and the meeting should be documented on a pre-start sheet with attendee list and topics covered.

Unit of Competency — a standardised qualification unit within the Australian Qualifications Framework that specifies the skills and knowledge required for a specific task. The relevant construction units include CPCCWHS1001 (General Construction Induction, the White Card), RIIWHS204E (Work Safely at Heights), RIIMPO320F (Conduct Civil Construction Excavator Operations), TLILIC0005 (Licence to Operate a Boom-type EWP above 11m), and CPCCLSF2001A (Use Small Plant and Equipment). A SWMS that references training requirements should cite the current unit codes rather than superseded units.

White Card — the common name for the General Construction Induction Training card issued under CPCCWHS1001. Required for all workers on a construction site regardless of their trade or role. The card is valid nationally and does not currently expire, although some states have considered introducing renewal requirements. The White Card covers general WHS awareness and does not substitute for site-specific induction or SWMS briefing. Contractors should verify White Card currency as part of the pre-start induction process.

WHS Act 2011 — the Work Health and Safety Act 2011 is the primary WHS legislation in NSW, Queensland, South Australia, Tasmania, the Northern Territory, the ACT, and at the Commonwealth level. Western Australia harmonised with the model WHS framework in 2022. The Act establishes the duty of care, the consultation obligations, the notifiable incident framework, and the enforcement provisions. Victoria operates under the separate Occupational Health and Safety Act 2004, which imposes similar duties with different terminology (employer and employee rather than PCBU and worker).

WHS Management Plan — a project-level safety document required under WHS Regulation 2025 section 309A for construction projects with a contract price of $250,000 or more. Prepared by the principal contractor and describes the systems, procedures, and arrangements for managing WHS on the project. Must include SWMS collection and review arrangements, consultation procedures, incident management, induction verification, site rules, and retention arrangements. The plan sits above individual SWMS in the documentation hierarchy.

Zero Harm — a workplace safety aspiration that no worker should be injured or made ill by their work. While achieving literally zero harm is debated among safety professionals — some argue the goal is unrealistic and drives unhelpful metric behaviour — the underlying principle drives continuous improvement in safety management systems. A well-managed SWMS library, an active consultation framework, and responsive amendment in response to near-misses all contribute to the zero harm direction of travel, even if the absolute target is never permanently achieved on any particular project.
