ASBESTOS REMOVAL PROCESS: FROM INSPECTION TO DISPOSAL

Asbestos removal is a highly regulated and complex process due to the health risks associated with asbestos exposure. Here’s a detailed guide covering each step from inspection to disposal:

Inspection and Assessment

Initial Inspection:

• UKAS Accredited Asbestos Surveyor: Hire a certified asbestos surveyor to conduct a thorough survey in compliance with the HSE Guidance Note Asbestos: The survey guide (HSG 264). They will identify asbestos-containing materials (ACMs) in the building.
• Sample Collection: The surveyor competently trained (P402) collects samples of suspected materials for laboratory analysis to confirm the presence of asbestos.

Risk Assessment:

• Condition of ACMs: Assess whether the asbestos is friable (easily crumbled and airborne) or non-friable (less likely to release fibres).
• Location and Quantity: Determine the amount and location of ACMs, which helps in planning the removal strategy.

Planning and Notification

Development of Removal Plan:

• Detailed Plan: Create a detailed abatement plan that includes methods for removal, type of protective equipment, and disposal procedures and Risk Assessments.
• Regulatory Compliance: Ensure the plan complies with The Control of Asbestos at Work Regulations 2012, local and national regulations.

Notification:

• Regulatory Bodies: Notify relevant regulatory bodies about the planned asbestos removal with submission of ASB5 for Notifiable works or ASBNNLW1 for some other Asbestos Containing Materials. Obtain other necessary permits and approvals.
• Building Owners: Inform owners about the project, potential risks, and safety measures.

Preparation of the Work Area

Containment:

• Isolation: Seal off the work area using polythene sheeting and create a negative pressure environment with the use of Industry Specific air movers fitted with HEPA filters to prevent asbestos fibres from escaping.
• Decontamination Units: Set up decontamination units for workers to enter and exit the work area safely.

Safety Measures:

• Signage: Post warning signs around the work area to alert individuals of the asbestos hazard.
• Personal Protective Equipment (PPE) and Respiratory Protective Equipment (RPE): Provide workers with appropriate PPE and RPE, including positive pressure respirators, disposable coveralls, gloves, eye protection and footwear.

Removal Process

Wet Removal:

• Dampening: Wet the ACMs to reduce the release of asbestos fibres during removal.
• Careful Removal: Gently remove the ACMs using hand tools. Avoid breaking the materials to minimise fibre release.

Encapsulation (if necessary):

• Sealing ACMs: In some cases, encapsulation might be used instead of removal. This involves applying a sealant to encase the asbestos material, preventing fibre release.

Cleaning and Decontamination

Initial Cleaning:

• HEPA Vacuums: Use HEPA-filtered vacuums and wet cleaning methods to remove asbestos dust and debris from surfaces.
• Visual Inspection: Conduct a thorough visual inspection to ensure no visible debris remains.

Final Cleaning:

• Air Monitoring: Perform air monitoring tests by a fully independent UKAS accredited analytical Laboratory to check for airborne asbestos fibres. Continue cleaning until air quality meets regulatory standards.
• Decontamination: Workers undergo decontamination procedures before leaving the work area.

Waste Disposal

Packaging:

• Sealed Containers: Place removed asbestos materials in double-layered, leak-proof bags or containers. Label them according to regulatory requirements.

Transport:

• Licensed Transporter: Hire a licensed hazardous waste transporter to carry the asbestos waste to a designated disposal facility with completion of a Waste Consignment note for each movement to ensure compliance with the Hazardous Wase Regulation 2005.

Disposal:

• Approved Landfills: Dispose of asbestos waste at approved landfills or waste transfer stations specifically designated to handle hazardous materials.

Final Clearance and Documentation

Clearance Inspection:

• Independent Inspector: Have an independent UKAS accredited analytical Laboratory will conduct a final clearance inspection to ensure the work area is free of asbestos contamination.
• Air Quality Tests: Perform final air quality tests to verify that asbestos levels are within safe limits.

Documentation:

• Records: Maintain detailed records of the entire process, including inspection reports, removal plans, air monitoring results, and waste disposal documents.
• Regulatory Submission: Submit required documentation to regulatory bodies to demonstrate compliance.

Post-Removal Activities

Monitoring:

• Periodic Checks: Conduct periodic checks and air monitoring, if required, to ensure no re-contamination occurs.
• Maintenance: Implement a maintenance plan for any remaining non-friable ACMs that were not removed but are still in place.

Asbestos removal is a meticulous process involving multiple stages to ensure safety and regulatory compliance. Proper planning, execution, and documentation are crucial to effectively manage the risks associated with asbestos exposure.
