Asbestos Abatement Technicians

If asbestos is found to be present in a building, technicians assess its condition. When materials such as ceiling tiles or wall panels are determined to be undamaged, trained technicians coat them to seal them. Asbestos is removed only in cases of serious damage because it can cost a building owner a great deal of money and the process can be dangerous when not performed properly. If the materials are damaged, technicians install a covering to keep the fibers from being released into the air of the room.

Asbestos building inspectors collect samples and analyze them under a microscope in a laboratory. If a sample tests positive, the asbestos must be contained or removed in accordance with strict federal and state regulations.

Asbestos abatement technicians who have been trained in a state-approved program remove the asbestos with a variety of tools, procedures, and safety measures. They first prepare an area for work, which involves putting in a series of enclosures and possibly constructing scaffolds. In order to protect themselves and the areas outside of the enclosure, technicians wear disposable protective gear from head to toe and breathe through special masks. Using the "wet method," technicians apply a mixture of water or other wetting agent to the asbestos to prevent the release of particles into the air. They use a variety of hand tools, such as scrapers and guns that spray chemicals, depending on the kind of material being removed. Mechanical tools are never used for fear of spreading fibers into the air. An air monitor continuously takes samples to ensure hazardous particles are few and are kept within the containment area.

Technicians then place the materials in plastic bags and prepare them for transport to a disposal site. Once the work has been completed, inspectors again survey and analyze the site to determine if it has been properly cleaned. If samples still show signs of asbestos, technicians must return to the site to remove any remaining asbestos-containing materials. If the work site is clear, the technicians then take down the enclosures and scaffolds, and the site is again open for use.
