Asbestos in Soil: Identifying Risks and Ensuring Safe Remediation Practices

Asbestos in soil is a serious concern. When disturbed, asbestos fibres can spread through the air and create health risks if inhaled. Exposure to these tiny fibres can lead to severe lung conditions like asbestosis and lung cancer.  

Knowing how to identify and safely manage asbestos in soil is essential for protecting both workers and the environment. 

Why Asbestos in Soil is Dangerous 

Asbestos is a natural mineral once widely used in building materials for its heat resistance and durability. Even though it has been banned in many places, asbestos still exists in older buildings, waste areas, and even soil due to old construction or illegal dumping. Over time, asbestos can break down and mix with soil, where it remains hazardous if disturbed. 

When soil containing asbestos is moved or disturbed during digging, construction, or landscaping, the tiny fibres can be released into the air. Once inhaled, they can lodge in the lungs, causing health issues that may not appear until many years later. This is why finding and safely managing asbestos in soil is crucial. 

The Need for Soil Testing for Asbestos 

Identifying asbestos in soil requires specialized testing by trained professionals. Regular soil tests may not detect asbestos; instead, specific asbestos testing methods must be used. Apex Environmental provides asbestos soil testing to help detect and measure asbestos fibres in various types of soil. 

Soil testing involves collecting samples from different areas and depths to determine the level of asbestos present. This information is essential for creating a safe plan to manage or remove the asbestos. Routine testing also helps businesses detect asbestos early, preventing accidental exposure and ensuring safer working conditions. 

Rules for Handling Asbestos-Contaminated Soil 

Strict rules and guidelines exist to ensure asbestos in soil is handled safely. Regulations may differ by country, but they generally require businesses to follow safe practices for managing asbestos. In South Africa, the Asbestos Abatement Regulations under the Occupational Health and Safety Act outline specific rules for handling asbestos safely. 

Only licensed professionals are allowed to manage asbestos in soil. These professionals use protective gear and follow dust control methods to prevent fibres from spreading. Asbestos waste must also be disposed of at approved facilities that can handle hazardous materials safely. Following these guidelines helps protect employees, reduce legal risks, and prevent environmental harm. 

Safe Methods for Cleaning Up Asbestos in Soil 

Once asbestos is found in soil, safe cleanup methods are necessary. Here are some common ways to manage asbestos in soil: 

• Containment & Dust Control: It’s important to keep dust from spreading. Workers may use water to wet the soil and stop fibres from becoming airborne. In high-risk areas, containment materials may be added to lock the fibres in place. 

• Excavation & Removal: If the contamination is severe, removing the soil may be the safest option. Licensed workers carefully dig up the soil and transport it to special disposal facilities. This process requires strict controls to keep asbestos fibres from spreading. 

• Encapsulation & Capping: In some cases, it may be safer to cover or seal asbestos rather than remove it. It involves applying a special coating to the soil that binds the fibres. Capping involves covering the area with a layer of clean soil or concrete to prevent exposure. 

• Ongoing Monitoring: For sites where removal isn’t possible, regular monitoring and controls help manage asbestos safely. Routine checks ensure the asbestos remains contained and doesn’t pose a risk to workers or the community. 

Educating Employees About Asbestos Risks 

Education is a key component in managing asbestos risks in the workplace. Companies should provide training to employees about the dangers of asbestos in soil, how to recognise potential hazards, and the importance of following safety procedures. 

Training programs should cover the following topics: 

• Understanding Asbestos: Employees should learn what asbestos is, where it can be found, and the health risks associated with exposure. 

• Identifying Risks: Workers should be trained to identify signs of potential asbestos contamination, such as old building materials or soil that might have been disturbed during construction activities. 

• Safety Procedures: Employees must know the procedures for reporting suspected asbestos, how to handle potential exposure situations, and the importance of using personal protective equipment (PPE). 

• Emergency Response: Training should include what to do in case of accidental disturbance of asbestos-containing soil, including evacuation procedures and how to contact trained professionals for assistance. 

By educating employees, companies can create a safer work environment and ensure that everyone is aware of the risks associated with asbestos in soil. This proactive approach not only protects individual workers but also helps to foster a culture of safety throughout the organisation.
