This World Day for Safety and Health at Work, make sure your site is safe and free of contamination! Know how a polluted site and building can make your workplace a health risk for your workers and can make you liable to legal penalties, and how remediation services can help.
Key Takeaways
- PCBUs must prioritise environmental remediation and site assessments, as hidden hazards directly impact worker health and safety, regulatory compliance, and legal liability
- Staying compliant requires aligning with ASC NEPM, state EPA legislation, Australian WHS laws, CRC Care guidelines, and the new Workplace Exposure Limits
- Proactive hazard identification protects employees from invisible, long-term health risks, ensuring a safer, productive workplace and mitigating significant financial penalties.
The World Day for Safety and Health at Work, observed every year on 28th April, is a reminder that protecting our workers is paramount. It is not just getting them hard hats and protective vests; with the ever-evolving construction, manufacturing, and industrial scene in Australia, workplace health and safety is often overlooked!
Although this year’s theme covers the aspect of “healthy psychosocial working environment,” you cannot ensure the psychosocial health with unhealthy air and risky workplace settings. In this case, site assessment and remediation services can help ensure worker safety. Let’s see how.
Why Australian Workplaces Need Environmental Remediation for Worker Safety?
As per CRC Care’s 2024 report, Australia has more than 200,000 potentially contaminated sites, the majority of them being located in urban areas. The contamination in these areas, where 75 to 80% of the population lives and works, can impact housing, industry, health, and recreation. This makes the presence of contamination not just an environmental issue but also a WHS issue. So, we cannot simply leave the areas without making sure that the contaminants are remediated.
Why is Remediation Essential for Australian Workplaces?
The health and safety hazards in Australia that specifically need remediation include:
- Airborne contaminants (fumes, dust, gases, vapours)
- Biological hazards (mould, fungi, bacteria)
- Chemical hazards
- Physical contaminants like radiation
Now, considering the workplace safety situation in Australia, most of the aforementioned issues contribute to the following data.
| Metric | Figure | Source |
|---|---|---|
| Worker fatalities in 2024 | 188 | |
|
Serious workers’ compensation claims (2023–24) |
146,700 | Safe Work Australia |
| Industries that accounted for 80% of fatalities in 2024 | Agriculture, Transport, Construction, Manufacturing, Health, Public Administration |
Table 1: Australian Workplace Safety at a Glance
Contaminated site workers are also disproportionately represented under these statistics; however, they are rarely tracked and recorded as a distinct cohort. This shows that Australia, despite having proper applications of the WHS (Work Health and Safety) Act in Australia 2011, is not totally safe from contamination.

What is Environmental Remediation and Why Does it Involve Risk?
Environmental remediation is a systematic process where appropriate tests are conducted to identify, contain, treat, and remove contaminants from soil, air, groundwater, and buildings. Agencies like us offer services that help restore sites to a safe condition, removing the contamination or sources of contaminants for future use.
Why is it Risky?
- Usually, remediation sites include areas like former industrial land, mining sites, military bases, fuel depots, fire service training grounds, and pre-1990-made buildings with asbestos. Workers on these sites are exposed to the hazards at every phase (from investigation, excavation, to treatment and post-remediation monitoring).
- Poorly managed sites or disturbed sites (usually during renovation or surface cleaning) can spread contamination rather than containing it, creating new WHS risks.
Types of Remediation Work and Associated Hazards
- Building Demolition/HAZMAT Surveys: Friable asbestos, lead paint, and synthetic mineral fibres
- Air and Dust Monitoring: Asbestos fibres and crystalline silica that need NATA-accredited monitoring
- Soil Excavation: Can disturb buried asbestos, hydrocarbon plumes, heavy metals, and generate hazardous dust
- Groundwater Treatment: There is a risk of vapour intrusion from volatile organic compounds and mixed PFAS that are harmful for consumption
- Waste Transport and Disposal: Workers can be exposed to them during loading, including spill risks after or before containment on public roads during transport
- Post-Remediation Monitoring: Dermal and inhalation exposure that can have long-term effects if proper safety measures aren’t undertaken
The Invisible Hazards That Need Site Assessment Before Remediation
Not all workplace hazards are visible to the naked eye. These are the most dangerous threats, and they are often microscopic, where the effects might take years or decades to show up. Here are the ones usually common in almost all Australian States.
*6PPD-Quinone is another emerging contaminant in 2026 that comes from tire wear and should be considered as a hazard that requires remediation as well.
| Contaminant | Exposure Route | Health Risk | Australian Regulatory Status |
|---|---|---|---|
| Asbestos (ACM/friable) | Inhalation | Mesothelioma, lung cancer, and asbestosis | Banned nationally as of 2003 |
| PFAS (PFOS, PFOA, PFHxS) | Dermal, ingestion, inhalation | Liver damage, immune disruption, classified carcinogen (PFOA) / possible carcinogen (PFOS) by WHO IARC (2023) | PFOS, PFOA, PFHxS banned from import/manufacture from 1 July 2025; IChEMS registered |
| Crystalline Silica | Inhalation | Silicosis (irreversible), lung cancer | Engineered stone ban on uncontrolled processing; new WES/WEL list effective 1 Dec 2026 |
| Heavy Metals (lead, arsenic, chromium) | Dermal, inhalation, ingestion | Neurological damage, cancer, organ failure | Regulated under ASC NEPM and WES/WEL list |
| Hydrocarbons / TPH | Inhalation, dermal | Respiratory damage, carcinogenic | Site-by-site risk assessment; CRC CARE National Remediation Framework |
| Volatile Organic Compounds (VOCs) | Inhalation (vapour intrusion) | Central nervous system damage, cancer | Soil vapour extraction required; air monitoring mandatory |
Table 2: Invisible Hazards That Need Site Assessment
Not ensuring proper remediation services and workplace contamination safety for these hazards, if you are running a corporation, will require you to pay compensation, fines due to failure to follow the law, and it can even lead to imprisonment in some cases.
Even if you are not the original polluter, as the new land owner, you might also be held liable for site contamination in some states, as per the “Polluter Pays Principle”. For example, in NSW, the current owner can be held liable if they knew contamination would occur but failed to prevent it. In Queensland and Western Australia, if the original polluter cannot be found, the next person in the hierarchy of responsibility is held liable.
Kwinana (WA), Botany (NSW), or The Port of Brisbane (QLD) are high-density industrial zones, and workplaces in these areas must ensure proper site testing and remediation.
Why Remediation Cannot Be Separated From Workplace Safety
Under Australia’s Model WHS Laws, PCBUs (Persons Conducting a Business or Undertaking) have a duty to minimise or eliminate risks from workplaces. Contaminated sites that are not properly assessed are sites with unknown hazards, and they fail WHS requirements.
This applies to the psychosocial health theme of World Day for Safety and Health at Work 2026. Because working in contaminated sites can make people stressed and uncertain about health impacts. Furthermore, they can also be kept in the dark without adequate communication about exposures, causing more worry.
Australian Regulatory Framework – Things You Should Know
In Australia, site assessment and remediation services are governed by the following federal and state regulations. So, the need to stay compliant with these laws also shows why remediation cannot be separated from workplace safety.
- National Environment Protection (Assessment of Site Contamination) Measure (ASC NEPM): Operates under the National Environment Protection Council Act 1994 (Cth) to provide adequate protection of human health and the environment where site contamination has occurred.
- CRC Care’s National Remediation Framework and Guidance of Australia (NRF): It provides nationally harmonised methods for remediation and management of contaminated sites in Australia
- State-based EPA legislations (Includes: Contaminated Land Management Act 1997 NSW; Environment Protection Act 1993 SA; Environment Protection Act 1986 WA)
- Safe Work Australia’s Model WHS Laws and the duties of PCBUs
- WES to WEL Transition: from 1 December 2026, new Workplace Exposure Limits will replace WES (Workplace Exposure Standards) for airborne contaminants
| Regulator / Body | Role |
| Safe Work Australia | National WHS policy, model laws, WES/WEL list |
| State EPAs (NSW EPA, EPA WA, EPA SA, EPA VIC, etc.) | Contaminated land regulation, remediation oversight, and EPA audits |
| CRC CARE | Research, national remediation guidance |
| ASSEA (Asbestos and Silica Safety & Eradication Agency) | Asbestos and silica policy, national strategy |
| State WHS Regulators (WorkSafe VIC, SafeWork NSW, WorkSafe WA, etc.) | Enforcement, prosecutions, inspections |

What Workers, Employers, and Site Owners Should Do Right Now
Here is what you should do if you belong to one of the following groups of audience.
| Audience | Key Responsibilities & Actions |
|---|---|
| Workers | Know your rights under the Model WHS Laws under the WHS Act (2011) and request site-specific HASPs and SDS (For Victoria, the Occupational Health and Safety Act 2004 is applicable). Ensure PPE fits correctly (especially respirators) and request health monitoring for lead, asbestos, or PFAS. Report unusual odours or site changes immediately. |
| Employers (PCBUs) | Commission Phase 1 & 2 Assessments before work starts. Align monitoring programs with the December 2026 WEL list. Use NATA-accredited consultants like SERS for validation and maintain rigorous records to avoid significant Category 1 penalties. |
| Owners & Developers | Perform environmental due diligence prior to acquisition to mitigate financial liability. Hire EPA-certified practitioners and ensure remediation methodologies strictly protect workers, neighbours, and the public from cross-contamination. |

Frequently Asked Questions
1. How Do I Know if My Building Contains “Legacy” Contaminants Like Lead or Asbestos?
First, review your building’s age. If it was made before 1990, it will require a hazardous materials (HAZMAT) survey, and you will need to register it with your local council or state EPA to identify hidden risks.
2. What is the Difference Between a Phase 1 and a Phase 2 Environmental Site Assessment?
Phase 1 involves historical research and site inspections; Phase 2 requires actual soil, water, or air sampling that is tested in NATA-accredited labs to confirm contamination.
3. Does Professional Indemnity Insurance Cover Me if a Remediation Project Fails?
Standard policies vary depending on the state you’re in; however, hiring certified practitioners like SERS will ensure that your work meets regulatory standards, which is essential for maintaining valid insurance coverage.
4. How Often Should Workplace Air Quality Be Monitored on a Remediation Site?
Monitoring frequency depends on the risk level and contaminants present. However, continuous or daily monitoring is recommended if the site has high-disturbance excavation activities going on.
