Many buildings contain asbestos, which was used in spray-applied flame retardant, thermal system insulation, and in a variety of other materials. Typically, the part of the building from which asbestos is being removed has to be sealed off in order to prevent contamination of the other areas. Methods of sealing off an area often include the use of Polyethylene film, duct tape and negative air pressure machines which are fitted with HEPA filters. The idea is that the contained area is pulling fresh air in as to not allow asbestos fibers into the surrounding environment.
Removal is not the only means of asbestos abatement. Asbestos and asbestos-bearing materials may be “enclosed” or “encapsulated” to prevent building occupants from being exposed to the fibers. An asbestos-containing building that is to be torn down may have to be sealed (see third picture on right), and to have its asbestos safely removed before ordinary demolition can be performed. The asbestos removal may take longer and cost more than the actual demolition.
