REMOVAL PROCEDURES

Typically it is necessary to relocate some residents temporarily if removal is performed on an occupied building. The part of the building from which asbestos is being removed must be sealed off with critical barriers to prevent contamination into other areas. Sealing off an area usually involves using polyethylene plastic, duct tape and negative air pressure machines which are fitted with HEPA filters. This is done so that the contained area is pulling fresh air in, while not allowing asbestos fibers to reach outside of the containment. With a well setup containment with critical barriers, if some sort of a leak were to occur in the containment, the air would leak inwards rather than outside of the containment.

During asbestos removal, special vacuum called a HEPA vacuum is required for asbestos containment (class H) in order to safely clean all asbestos fibers from the work area.

An asbestos-containing building that is going to be demolished is required to have the asbestos removed before ordinary demolition can be undertaken. In some cases, it can take more time and money for the asbestos removal process than the actual demolition. OSHA (Occupational Safety and Health Administration) must be notified prior to any demolition jobs regardless if asbestos is present or not, and most renovation projects. SCAQMD (South Coast Air Quality Management District) requires a notification for any demolition or renovation job of more than 100 sq. ft.
