Mine sites harbour a complex array of hazardous materials. From heavy metals to flammable material and asbestos, these contaminants pose significant risks to human health and the environment if they’re not handled properly.
That’s why it’s essential to partner with an experienced mine site clean-up company and start planning early.
The Types of Hazardous Materials We Encounter in Mine Site Clean-Ups in Perth
Heavy metals
Examples: Lead, mercury and arsenic.
These metals can be found in mining waste, contaminated soils, and old equipment. They pose significant health risks, including neurological damage and cancer, and can severely impact local ecosystems.
Chemicals
Examples: Cyanide, sulfuric acid, solvents and nitric acid.
The chemicals used to separate minerals from ore and in downstream processing are often harsh and heavily regulated. Mishandling them in mine site clean-ups can lead to acute poisoning, respiratory issues, and environmental degradation.
Radioactive materials
Examples: Uranium, thorium, potassium and their decay products, radium and radon.
Australia is the world’s third-largest uranium producer. Managing uranium and radioactive waste properly will decrease cancer risks and prevent serious health issues. It’s important to consider the long-term impact of irradiated ore and waste on mine site rehabilitation in Perth.
Asbestos
Sources: Old buildings, fencing, roofing and insulation, and some rocks and soil in Western Australia.
Asbestos fibres can cause severe respiratory diseases, including asbestosis and mesothelioma. Although its import and use has been banned since 2003, we still find it in older mine site clean-ups in Perth and remote areas.
Explosives and flammables
Examples: Fuel, oil, explosive slurry, dry wood, discarded fuel tanks.
Flammable substances require specialised handling and storage to prevent accidents during mine site clean-ups and avoid a catastrophe during mine site rehabilitation. Explosives are a special category of hazardous material with reams of regulation and safe handling requirements.
Handling Hazardous Materials Safely During Mine Site Clean-Ups
Mine site clean-up projects should start well before the mine reaches the end of its useful life. This gives enough time to plan for and mitigate the risks.
As an experienced mine site clean-up partner, we work closely with you to develop efficient, safe and effective plans. Close collaboration ensures we achieve your goals and proactively address concerns raised by the community.
However, with thousands of abandoned sites and tonnes of disused mining equipment dotted around Western Australia, it’s not always possible to plan ahead.
In our experience, these mine site clean-ups are even more complex. Without an accurate record of equipment, processes and substances, we often don’t know exactly what we’re getting into.
Caution is key. We approach every mine site clean-up and mine site rehabilitation in Perth with a conservative, risk-first mindset.
However, our well-developed processes mean the project isn’t held up by endless discussions.
Initial site assessment
We start by conducting comprehensive surveys to locate and identify hazardous substances. This allows us to assess risks and develop detailed plans.
Containment and isolation
Our techniques include using barriers and containment systems to prevent the spread of hazardous materials.
Depending on the nature and severity of the containment risk, we also develop site-specific isolation solutions.
Our goal is to avoid cross-contamination and keep everyone safe. Once we achieve that, we can begin removing the offending material.
Removal, transportation and disposal
Disturbing hazardous material is one of the riskiest stages of the process. We use specialised tools and procedures, and plan transportation routes carefully to minimise risk.
Where possible, we will recycle scrap metal to generate high-grade material for the circular economy. For all other hazardous materials, we adhere to strict regulations and partner with trusted, certified disposal facilities.
Mine site rehabilitation
Mine site clean-ups don’t end when all hazardous material is taken away. That’s merely the tip of the iceberg.
After removing contaminants, cleaning the site and recycling valuable material, we begin the mine site rehabilitation process. Depending on your plans for the site, this could mean repurposing the land, making structures safe for visitors, monitoring the soil for contamination, or all the above.
Safety comes first for everyone
We adhere to rigorous safety protocols to protect our workers and the environment. Personal Protective Equipment (PPE) is tailored to the specific hazardous materials encountered on-site, ranging from respirators and gloves to full-body suits.
In addition to PPE, we implement comprehensive site safety measures:
- Safety Data Sheets (SDS) prepared for all identified hazardous materials
- Comprehensive training to handle hazardous materials correctly
- Emergency response plans to address accidents or spills
- Clear site signage and effective hazard communication
Safety is our top priority. By following strict protocols, we keep everyone safe and exceed compliance standards.
Compliance, Regulations and Penalties
Handling and disposing of hazardous materials in mine site clean-ups is subject to stringent Australian and Western Australian legislation.
The two overarching regulations for hazardous chemicals are:
- Work Health and Safety (General) Regulations 2022
- Work Health and Safety (Mines) Regulations 2022
We won’t go into all the details here. The Mines Regulations, for instance, dedicates over 120 pages to handling and managing hazardous materials.
The key takeaway is that non-compliance with the regulations carries substantial financial penalties.
For example, incorrect disposal of asbestos waste or PPE contaminated with asbestos can attract fines of up to $7,000 for individuals and $35,000 for body corporates. Incorrectly labelling asbestos-contaminated materials carries the same steep penalties.
In other words, you could face fines of $14,000 personally or $70,000 for the company for incorrectly discarding old fencing during a mine site clean-up in Perth.
Each category of hazardous material carries similar penalties. These fines reflect the critical need for proper handling by certified and trained professionals.
Maintaining accurate records of hazardous materials, including their handling and disposal, is also crucial for compliance and transparency.
