Asbestos FAQ

What is asbestos and why should I be concerned about it?

Asbestos Fiber

Asbestos Fiber

Asbestos is a mineral that for the last century appears in thousands of products for its insulating, acoustical and fire protective properties. Common products that contain asbestos include pipe insulation, floor and ceiling tile, spray-on insulation, boiler wrap insulation and electrical appliances such as your toaster and hair dryer. Asbestos-containing materials (ACM) are found in many environments including industrial and commercial facilities, schools and universities, and residential properties.

Once the fibers become airborne (usually by disturbing the product that contains them), they are easily inhaled into the lungs. Once in the lungs, these needle-like fibers can penetrate the lung tissue and the lining that holds the lung in place (pleura). This begins the process which can eventually lead to asbestosis, lung cancer, mesothelioma, or various other diseases.

How do I know if my home or facility contains asbestos?

Wall Demolition

The only way to know if your home or facility contains asbestos is to have it inspected by an accredited Asbestos Building Inspector. In fact, all commercial / industrial buildings built before 1981 require an inspection.

Homeowners are not required to have their homes inspected for asbestos; however, renovation work by a contractor requires an asbestos inspection.

What are some examples of materials that contain asbestos?

Common building materials that contain asbestos include pipe insulation (including the wrap on fiberglass insulation), spray-on fire proofing, floor tile, ceiling tile, duct wrap, hard and soft plaster, drywall joint compound, ceramic tile bedding compound, glazing and caulk, light reflector paper, mastic, vermiculite insulation (in exterior walls and attics) and roofing materials.

What is Transite?

Transite originated as trade name created for a line of asbestos-cement products, including boards and pipes. In time it became something of a generic term for other companies’ similar asbestos-cement products, and later an even more generic term for a hard, fireproof composite material, fiber cement boards, typically used in wall construction.

The use of asbestos to manufacture transite phased out in the 1980s. Previously transite made of cement, used varying amounts (12-50%) of asbestos fiber to provide tensile strength (like the steel in reinforced concrete), and other materials. It was often used in furnace flues, shingles, siding, and wallboard for areas where retarding fire is particularly important. Walk-in coolers for large supermarkets, restaurants and butcher shops in the 1960s, 1970s and even the 1980s also used transite. Other uses included roof drain piping, water piping, sanitary sewer drain piping, and HVAC ducts. Because cutting, breaking, and machining asbestos-containing transite releases carcinogenic asbestos fibers into the air, its use has declined. Transite removal and disposal requires the services of an asbestos removal contractor. To see pictures of transite materials click here. For more information   Contact AADS-LLC .

What do I do if my home or facility contains asbestos?

Asbestos Roofing Remediation

Unless the asbestos material is crumbling and in poor condition, it may safer to leave it alone as it is only a health hazard if it becomes airborne. If the material is crumbling or deteriorating, or if you are going to renovate, retaining an asbestos removal contractor is the best course for homeowners, and is required for commercial / industrial buildings.

The EPA and each state have developed helpful documents to aid building owners with their responsibilities. View them through these links or Contact AADS-LLC for more information.:

What is the difference between Abatement and Remediation?

The EPA website defines Asbestos Abatement as the procedures to control fiber release from asbestos-containing materials in a building or to remove them entirely, including removal, encapsulation, repair, enclosure, encasement, and operations and maintenance programs.
Asbestos Remediation is not specifically defined but the consensus is that it is a permanent action to control fiber release that does not include the removal of the ACM.

What should I expect from an asbestos abatement contractor?

Regulatory requirements vary based on the type of material, its condition, the quantity involved, and other factors. Most work involving friable asbestos is performed within  negative pressure enclosures or within a glovebag.

If the work is to exceed 160 square feet or 260 linear feet of friable asbestos-containing materials, the State Asbestos Program must be notified 10 days prior to removal.
