Asbestos Removal Services in London and Essex

Non-licensed asbestos removal involves working with asbestos-containing materials (ACMs) that are deemed lower risk and do not necessitate a license from the Health and Safety Executive (HSE). 

Although these tasks don't require a license, they must still be executed safely and in accordance with the Control of Asbestos Regulations 2012 to mitigate the risk of asbestos exposure. 

**Characteristics of Non-Licensed Work** 

Work is classified as non-licensed if it includes non-friable materials in good condition that will not be intentionally damaged during removal. Non-friable materials are less likely to release asbestos fibers when disturbed, as the fibers are securely encased within a matrix like cement, paint, or plastic. The necessity of a license is determined by the associated risk of the work. 

**Common Non-Licensed Materials and Tasks** 

Various common ACMs and tasks typically fall under the non-licensed category, as long as they are handled with care: 

- **Asbestos cement products:** This includes items like roof sheeting and rainwater goods, provided they are removed intact without breaking them apart. This holds true even if the material is weathered but not significantly damaged. 

- **Textured decorative coatings:** The removal of these coatings can be classified as non-licensed if done carefully, such as by cutting around the backing board to ensure intact removal. 

- **Vinyl floor tiles:** Generally considered lower risk for non-licensed asbestos removal. 

- **Loosely fixed Asbestos Insulating Board (AIB) panels:** Tasks to access maintenance areas, like pipework or lighting repairs, can be non-licensed if the panels are simply unscrewed and removed with care. 

- **Encapsulation of ACMs:** If the materials are in good condition, encapsulation may be considered a non-licensed activity. 

**Important Considerations** 

Even for non-licensed work, proper training is crucial. Some non-licensed asbestos removal projects might still need to be reported to the local council or HSE, especially if the removal site is large or if the asbestos cement is in poor condition. It’s vital to implement appropriate control measures to prevent exposure. Misidentifying materials can pose significant risks; for example, a garage ceiling could either be asbestos cement (non-licensed) or Asbestos Insulation Board (potentially licensed), and sampling is often required to confirm the material type. 

Sterling Environmental Group, as a competent asbestos contractor, can provide guidance through risk assessment to determine if the work will be classified as non-licensed asbestos removal.

Licensed asbestos removal in the UK is a highly regulated process mandated by the Control of Asbestos Regulations 2012, primarily due to the severe health risks associated with asbestos fibres. This type of asbestos removal is reserved for more hazardous asbestos-containing materials (ACMs) that are likely to release fibres when disturbed.

Common asbestos removal methods prioritize safety and aim to minimize fibre release. Here's an overview of widely used techniques:

Wet Removal Method

The wet removal method is a standard technique where asbestos-containing materials (ACMs) are saturated with water or another wetting agent before and during removal. Wetting the ACMs prevents asbestos fibres from becoming airborne, which is especially effective for friable materials like asbestos insulation or spray-applied coatings.

Enclosure

Enclosure involves constructing airtight barriers around asbestos materials to contain fibers. This technique is useful for large areas, such as entire buildings or rooms, and air tests are performed to ensure the enclosure keeps the area safe.

Careful Disassembly

Careful disassembly involves taking apart structures containing asbestos piece by piece to minimize fibre release. Workers use hand tools instead of heavy machinery to avoid excessive disturbance.

Injection and Foaming

Injection and foaming involve injecting foams or wetting agents into ACMs. This method is similar to wet removal but uses injectors to pump the materials directly into the ACMs.

Other Considerations

Air Quality Monitoring: Continuous air quality monitoring is conducted inside and outside the sealed area to detect potential fibre leaks.  Isolation of HVAC Systems: Heating, ventilation, and air conditioning systems in the affected zone are temporarily shut down or sealed off.

When is a License Required?

A license from the Health and Safety Executive (HSE) is required for work involving:

Friable asbestos materials: These are materials that can be easily crumbled by hand, such as asbestos insulation, coatings, and lagging.

Work that is likely to disturb asbestos: This includes activities that may break up ACMs or cause them to become airborne, even if the material itself is not friable.

Certain types of Asbestos: Asbestos Insulating Board (AIB), Asbestos Thermal Insulation, Asbestos Paper: While some work can be non-licenced asbestos removal, many applications require a licensed contractor.

The Role of Licensed Contractors

Licensed asbestos removal contractors are specifically trained and certified to handle these high-risk materials safely. They must adhere to strict protocols for containment, personal protective equipment (PPE), air monitoring, decontamination, and waste disposal.
