Where Asbestos Hazards May Be Found In The Home

As per the document: Consumer Product Safety Commission andEnvironmental Protection Agencyand theAmerican Lung Association (The Christmas Seal People) - Asbestos In The Home
CPSC Document #453

Where Asbestos Hazards May Be Found In The Home

  • Some roofing and siding shingles are made of asbestos cement.
  • Houses built between 1930 and 1950 may have asbestos as insulation.
  • Asbestos may be present in textured paint and in patching compounds used on wall and ceiling joints. Their use was banned in 1977.
  • Artificial ashes and embers sold for use in gas-fired fireplaces may contain asbestos.
  • Older products such as stove-top pads may have some asbestos compounds.
  • Walls and floors around woodburning stoves may be protected with asbestos paper, millboard, or cement sheets.
  • Asbestos is found in some vinyl floor tiles and the backing on vinyl sheet flooring and adhesives.
  • Hot water and steam pipes in older houses may be coated with an asbestos material or covered with an asbestos blanket or tape.
  • Oil and coal furnaces and door gaskets may have asbestos insulation.

Dealing with Debris and Damaged Buildings

As per the EPA - EPA's guidance has been requested on the demolition of structurally unsound buildings damaged by Hurricane Katrina. Various federal regulations apply to building demolition activities. Areas of primary federal concern include asbestos demolition requirements, the proper disposal of electrical equipment containing PCBs (i.e., distribution transformers and capacitors) and storage tanks. EPA recognizes the difficult circumstances faced in demolishing structurally unsound buildings damaged by Hurricane Katrina may make full compliance difficult. However, in any event, you should take the actions set forth below to the extent feasible.

Efforts to restore the damaged areas to their pre-disaster condition often involve removing or repairing damaged structures. There may be a natural tendency at this stage to overlook certain hazards, such as asbestos, that are not immediately life threatening. However, such hazards are serious and may manifest themselves many years from the time of exposure and should be taken into consideration. Given the health hazards associated with asbestos, PCBs, lead, and other harmful substances, it is reasonable that adequate measures be taken during emergency situations to minimize exposure to such materials from the demolition of buildings.

The following guidelines are provided to help minimize the health, safety and environmental risks associated with the demolition of structurally unsound buildings (structures that remain standing but are in danger of imminent collapse). In the case of such buildings it would be unsafe to enter or inspect a structure to determine the amount, types, and location of building materials containing asbestos, PCBs, lead, or other harmful substances. This guidance does not apply to the demolition of hurricane damaged but structurally sound buildings.
This guidance remains in effect through December 31, 2005, and applies only to areas damaged by Hurricane Katrina.

To the extent feasible, efforts should be made to perform the following steps:

Asbestos Safety and Health Topics

As per the Occupational Safety & Health Administration (OSHA) 's website www.osha.gov - Asbestos is well recognized as a health hazard and is highly regulated. An estimated 1.3 million employees in the construction and general industry face significant asbestos exposure on the job. Heaviest exposures occur in the construction industry, particularly during the removal of asbestos during renovation or demolition. Employees are also likely to be exposed during the manufacture of asbestos products (such as textiles, friction products, insulation, and other building materials) and during automotive brake and clutch repair work. OSHA and the Environmental Protection Agency (EPA) asbestos rules are intertwined. The following questions link to information relevant to asbestos in the workplace.

Reduce Exposure to Asbestos

Steps to Reduce Exposure

It is best to leave undamaged asbestos material alone if it is not likely to be disturbed.
Use trained and qualified contractors for control measures that may disturb asbestos and for cleanup.

Follow proper procedures in replacing wood stove door gaskets that may contain asbestos.

If you think your home may have asbestos, don't panic!

Usually it is best to leave asbestos material that is in good condition alone. Generally, material in good condition will not release asbestos fiber. There is no danger unless fibers are released and inhaled into the lungs.

Do not cut, rip, or sand asbestos-containing materials.

Leave undamaged materials alone and, to the extent possible, prevent them from being damaged, disturbed, or touched. Periodically inspect for damage or deterioration. Discard damaged or worn asbestos gloves, stove-top pads, or ironing board covers. Check with local health, environmental, or other appropriate officials to find out about proper handling and disposal procedures. If asbestos material is more than slightly damaged, or if you are going to make changes in your home that might disturb it, repair or removal by a professional is needed. Before you have your house remodeled, find out whether asbestos materials are present.

When you need to remove or clean up asbestos, use a professionally trained contractor.
Select a contractor only after careful discussion of the problems in your home and the steps the contractor will take to clean up or remove them. Consider the option of sealing off the materials instead of removing them.

Asbestos Definitions and Facts

Asbestos - Definition

Asbestos - a fibrous amphibole; used for making fireproof articles; inhaling fibers can cause asbestosis or lung cancer

Asbestos Related Words

Amphibole - a mineral or mineral variety belonging to the amphibole group
Chrysotile - a gray or green fibrous mineral; an important source of commercial asbestos
Tremolite - a white or pale green mineral (calcium magnesium silicate) of the amphibole group used as a form of asbestos

Asbestos Facts

Asbestos is a family of naturally occurring minerals, found in serpentinite and other metamorphic rock

Because of its strength and resistance to heat, asbestos was used for insulation, heat resistant clothing, roofing and fire proofing. It was also used as an additive to ease the manufacture and application of ceiling and wall finishes, tape joint compounds, floor tiles and mastics.

Since many building materials can contain asbestos, remodel and repair activity in residential and commercial structures which disturbs asbestos-containing materials may cause the release of asbestos fibers into the air. There is no known health threat if asbestos-containing materials are in generally good condition and are left undisturbed.

Inhaling airborne asbestos fibers can increase the risk of developing certain lung diseases, including lung cancer, mesothelioma and asbestosis.

In the United States there are many regulations protecting children, employees, tenants, workers and others from exposure to asbestos. These include AHERA (schools), OHSA (workers), ASHARA (public buildings) and NESHAPS (emissions).

Types of Asbestos

There are two types of asbestos containing material:

Friable Asbestos-Containing Materials - contain over 1% asbestos and can be crumbled, crushed or reduced to powder by hand pressure when dry. Common examples of friable asbestos-containing materials are spray acoustic ceilings, acoustic tiles, plaster, pipe and duct wrap, and paper backing of linoleum.

Non-friable Asbestos-Containing Materials - are typically bound up with cement, vinyl, asphalt or some other type of hard binder. Some examples of non-friable asbestos building materials are cement/transite siding, vinyl floor tiles and stucco. Non-friable asbestos-containing material may become friable if it is crushed, crumbled, pulverized, or subjected to sanding, drilling, grinding, cutting, or abrading.
