Asbestos Insulating Board was most commonly used for fireproofing and thermal insulation, but it also had many other uses including common building materials like plasterboard and ceiling tiles. It can be difficult to distinguish between asbestos-insulating board items from non-asbestos material and because of its simplicity, asbestos insulation board can be used in many places throughout buildings for various purposes.
Asbestos insulation board is a product made from raw asbestos fibre mixed with other materials. Asbestos insulating boards are generally made up of 20% to 40% asbestos fibre and a calcium silicate or plaster mixture to give them a more rigid finish. While asbestos insulation board is mainly composed of Amosite (Brown), there are occasions when it may contain Crocidolite, (Blue) or Chrysotile, (White).
Uncontrolled asbestos insulation board removal can lead to airborne asbestos fibre levels. The exposure is 10 fibres per centimetre. This is 100 times more than the legally recognized control limit of 0.01 f/cm3. Uncontrolled asbestos insulation board removal is dangerous because asbestos exposure above the limit is much more hazardous than asbestos exposure below it. It's easy to see that working on asbestos insulation board requires a license. Only those licensed by HSE should be allowed to perform the work.
Good project planning is crucial for the removal of asbestos insulation board. No matter how large the project is. The following are essential for good project planning and assessment of removal requirements.
1. Once all paperwork and fact-finding has been completed, the project must now be notified to the HSE with an exact start date. It is required by law that licensed asbestos removal contractors notify the HSE 14 days before any work is performed. This can be done via their online form ASB5.
2. Before work can begin on the removal of asbestos insulation board, it is necessary to prepare the area. All paperwork must be available on site and ready for inspection, if necessary. All welfare facilities must be available and in compliance with current regulations. Access and work areas must be inspected and verified to be acceptable.
3. All items not required for the project must be removed from the work area. Pre-cleaning the area is required in many cases before the construction of the enclosure. To protect and warn others not directly involved in the asbestos removal process, it is important to have adequate warning signs and barriers.
4. The most important control measures are careful handling and fiber suppression. How the asbestos board was fixed will determine which removal method is used. The screws must be located and then the board should be carefully undressed to avoid any damage. If the asbestos insulation board is nail-fixed, the area that has been nailed should be carefully scored using a knife to minimize disturbance.
5. The asbestos insulation board that has been removed is carefully wrapped or bagged. Continue this process until all boards are removed. As the removal proceeds, any dust or debris that is released should be removed.
6. After all the asbestos insulation board has been removed and wrapped in double bags/wrapped, the time is right for the fine cleaning.
7. After the removal work is complete, the team will conduct a visual inspection of the site to ensure that it is in good condition, that the site's decontamination unit is functional, and that there is no clutter or obvious contamination.
All of these items are essential and it is clear why asbestos insulation board removal costs more than general demolition or removal work for other non-asbestos material. The cost of removing asbestos insulating board varies depending on the project.
