A SWMS, short for Safe Work Method Statement, is a specific legal document tied to High Risk Construction Work. Most routine cleaning, such as cleaning a standard office, gym, or retail floor, does not require a SWMS. SWMS is required when the cleaning work itself falls within an HRCW category, such as construction work involving a risk of falling more than 2 metres or work in or near a confined space.
Post-construction cleaning can involve these higher-risk activities because it often takes place on an active construction site, but being on a construction site does not automatically make cleaning work High Risk Construction Work. A construction cleaning service operating across Greater Sydney therefore needs to understand when a SWMS is legally required and prepare one before the relevant high-risk work starts. Getting that line right matters for a facility manager too: expecting a SWMS where it is not required, or missing it where it is, can indicate a misunderstanding of when the document actually applies.
What is a SWMS?
A SWMS, or Safe Work Method Statement, is a safety planning document required for work classified as High Risk Construction Work under the WHS Regulation 2025 (NSW). It sets out the high-risk activity being carried out, the hazards and risks associated with that activity, and the control measures used to manage those risks. In commercial cleaning, a SWMS applies when the cleaning work itself meets the relevant high-risk classification.
A SWMS is intended to be a practical planning and implementation tool, not a document that simply sits in a folder. It must be readily accessible to the workers carrying out the task, their supervisors, and other people who may be exposed to the risks covered by the SWMS. This allows everyone involved to understand the hazards, risks, and control measures before the work begins. Accessibility is therefore an important part of putting a SWMS into practice: a statement that workers cannot access or understand cannot effectively guide the work.
The site-specific nature of a SWMS is also important. A SWMS prepared for one job cannot simply be copied for another without reviewing whether the hazards and controls are still relevant. The risks can change with the location, equipment, work method, and conditions on site. A cleaning contractor working at heights in one warehouse and carrying out work in a confined space at another site needs the controls in each SWMS to reflect the work actually being performed, rather than relying on the same generic template for both.
When does commercial cleaning actually require a SWMS?
Commercial cleaning requires a SWMS when the work involves an activity classified as High Risk Construction Work. For cleaning, this can include construction work involving a risk of falling more than 2 metres, work in or near a confined space, or other activities that fall within the HRCW categories under the WHS regulations. The trigger is the activity and its classification, not the fact that the work is cleaning.
Post-Construction and Builders Cleaning
Post-construction cleaning on an active building site can involve situations where a cleaning contractor needs a SWMS, but being on a construction site does not automatically make every cleaning task High Risk Construction Work. Where the cleaning work itself involves an HRCW activity, such as a risk of falling more than 2 metres, the relevant SWMS must be prepared before that work starts.
High-Level Cleaning at Heights Over 2 Metres
Cleaning that involves construction work with a risk of a person falling more than 2 metres is classified as High Risk Construction Work. This can include certain high-level warehouse cleaning, atrium or high-window cleaning, or other cleaning tasks where the work creates that fall risk. The fall risk, rather than the cleaning method itself, is what brings the work within the SWMS requirement.
Confined-Space Cleaning
Cleaning in or near a confined space can fall within the High Risk Construction Work categories when the work is construction work. Examples may include work in tanks, pits, silos, or other spaces that meet the relevant definition of a confined space. These environments can involve restricted entry and exit and potentially hazardous atmospheres, so the work requires appropriate risk controls and, where it is HRCW, a SWMS before work begins.
Cleaning as a Subcontractor on a Construction Site
A cleaning contractor engaged as a subcontractor on a construction project may need to prepare a SWMS when its work involves High Risk Construction Work. The requirement comes from the nature of the work being carried out, not simply from the contractor’s status as a subcontractor or from being on a construction site. Where the cleaning contractor is carrying out HRCW, the PCBU responsible for that work must prepare, keep, comply with, and review the SWMS, while the principal contractor has duties to ensure the required SWMS is in place for HRCW on the project.
What must a compliant SWMS contain?
A compliant SWMS must cover four core areas: the High Risk Construction Work being carried out, the hazards and risks involved, the control measures used to manage those risks, and how those controls will be implemented, monitored, and reviewed. It must also be site-specific and written so the workers using it can understand it.
01. Identify the High Risk Construction Work
The SWMS must identify the specific High Risk Construction Work being carried out. This could include cleaning work involving a risk of falling more than 2 metres, work in or near a confined space, or another activity that falls within the defined HRCW categories.
02. Identify the Hazards and Risks
The SWMS must set out the hazards created by the high-risk activity and the risks those hazards pose to health and safety. These should relate to the actual work being carried out rather than relying on a generic list of hazards.
03. Describe the Control Measures
The SWMS must explain the control measures that will be used to eliminate or minimise the identified risks. The controls should match the hazards and the way the work will actually be performed on site.
04. Explain How the Controls Will Be Implemented and Reviewed
The SWMS must describe how the control measures will be put into practice, monitored while the work is underway, and reviewed when necessary. If the work changes or the existing controls are no longer suitable, the SWMS needs to be reviewed and revised.
Two Practical Requirements for a SWMS
Site-Specific
A SWMS needs to reflect the actual location, equipment, work methods, and conditions of the job. A generic template may provide a starting point, but it should not simply be reused without checking that the hazards and controls apply to the specific site.
Accessible and Easy to Understand
The SWMS must be readily accessible to the workers carrying out the task and written in a way they can understand and follow. A document that workers cannot access or understand cannot effectively guide the work on site.
What is the difference between a SWMS, an SDS, and a risk assessment?
A SWMS covers a specific High Risk Construction Work activity, an SDS covers the hazards and safe handling of a specific hazardous chemical, and a risk assessment covers workplace hazards more broadly. They are often confused because all three deal with safety, but each serves a different purpose and is triggered by different requirements.
The three documents answer three different questions. A SWMS answers, “How will this high-risk task be carried out safely?” and applies to High Risk Construction Work. An SDS, or Safety Data Sheet, answers, “What are the hazards of this chemical and how should it be handled safely?” It is provided by the manufacturer or importer for hazardous chemicals. A risk assessment answers, “What could cause harm in this workplace and how will those risks be controlled?” It forms part of the broader WHS process for identifying and managing risks, rather than applying only to high-risk activities.
| Document | What it covers | When it is required | Where it comes from |
|---|---|---|---|
| SWMS | A specific High Risk Construction Work activity, its hazards, risks, and control measures | For High Risk Construction Work | Prepared by the PCBU carrying out the high-risk work |
| SDS | The hazards, handling, storage, and emergency information for a specific hazardous chemical | For hazardous chemicals that require an SDS | Provided by the chemical manufacturer or importer |
| Risk assessment | Workplace hazards and the risks they create, along with how those risks are controlled | As part of the general WHS risk management process | Developed as part of the PCBU’s risk management process |
For a commercial cleaning contractor, all three can apply on the same job. A crew carrying out high-level warehouse cleaning might work under a SWMS for the relevant high-risk activity, have SDSs available for hazardous chemicals used on site, and operate under risk assessments covering the wider hazards of the work. The documents do not replace each other; they cover different parts of the same safety process.
Who is responsible for preparing a SWMS on a cleaning job?
The PCBU carrying out the High Risk Construction Work is responsible for preparing the SWMS before that work starts. For a cleaning job, this will usually mean the cleaning contractor itself when the contractor is carrying out the high-risk work and has the duty to document how that work will be performed safely.
The Cleaning Contractor’s Duty
A cleaning contractor carrying out High Risk Construction Work is a PCBU under WHS law, and the duty to prepare the SWMS sits with the PCBU carrying out that work. The contractor prepares the SWMS before the work begins, keeps it readily accessible to the workers carrying out the task, and reviews it if the work or conditions change. This applies whether the contractor is working independently or as one of several businesses operating on a larger site.
The Principal Contractor’s Role on a Construction Site
On a construction project, the principal contractor has a duty to obtain the SWMS before High Risk Construction Work starts on the site. A cleaning contractor working as a subcontractor therefore prepares its own SWMS for the HRCW it is carrying out, while the principal contractor manages the SWMS as part of its broader responsibilities for the construction site. The principal contractor must also take reasonable steps to ensure the high-risk work is carried out in accordance with the SWMS. The two duties sit alongside each other: the cleaning contractor prepares the SWMS, while the principal contractor has responsibilities for ensuring the required SWMS is in place and that the work is carried out in accordance with it.
Consultation With Workers
A SWMS should be prepared in consultation with the workers who carry out the task, as they can provide practical information about the hazards and how the work will be performed. Where a health and safety representative is involved, they should also be consulted as required. This helps the SWMS reflect the actual work rather than relying only on a manager’s assumptions about how the task will be carried out.
What should a facility manager check about a cleaning contractor’s SWMS practice?
A facility manager should check that a cleaning contractor understands when a SWMS is required, prepares one before applicable high-risk work starts, and can provide it when requested. The important point is not whether a contractor has a SWMS for every job, but whether it understands when the document applies and when it does not.
They Know the Trigger, Not Just the Document
A contractor that treats a SWMS as a blanket requirement for every job may not understand what actually triggers the requirement. A contractor should be able to explain which cleaning activities can involve High Risk Construction Work, such as certain work at heights or work in or near confined spaces, and which jobs are managed through other WHS controls. Understanding where the SWMS requirement applies helps ensure the document is used for the work it is intended to cover.
The SWMS Is Prepared Before Work Starts
A SWMS must be prepared before the relevant high-risk work begins, rather than written afterwards to satisfy a request. A facility manager can ask a contractor how it handles this on a high-risk job and expect a clear process for preparing, communicating, and reviewing the SWMS before work starts.
It’s Site-Specific, Not a Template
A contractor should be able to show that its SWMS reflects the actual site, including its heights, spaces, equipment, work methods, and conditions, rather than relying on a generic template for every job. A SWMS should address the hazards and controls relevant to the specific work being carried out at that location.
They Can Produce It and Explain It
A contractor should be able to provide the relevant SWMS when requested and explain how the workers carrying out the task are made aware of its contents. Since the SWMS needs to guide the work on site, the contractor should have a clear process for communicating the hazards, risks, and control measures to the crew rather than simply keeping the document on file.
Compliance That Knows When a SWMS Actually Applies
A cleaning contractor that prepares a SWMS for every job may not be applying the requirement correctly, while failing to prepare one for genuine High Risk Construction Work can create significant safety and compliance risks. Cleanin prepares a site-specific SWMS where High Risk Construction Work requires one, including applicable work at heights, in or near confined spaces, and other qualifying construction activities across Greater Sydney. Routine cleaning is managed through the WHS controls appropriate to the work being carried out.
