Asbestos was widely used in building materials throughout the 1900's. Use has decreased significantly since the 1980’s but there are some materials still in production today that contain asbestos. If your home was built prior to 2004, there is a high potential that asbestos-containing materials were used in its construction.
Prior to demolition of a residence constructed prior to January 1, 2004 you are required to hire an accredited inspector to conduct a thorough survey of all materials to be demolished to determine the presence of asbestos. If asbestos is found, it must all be properly removed and disposed of by a DEQ licensed asbestos abatement contractor prior to the demolition.
You can't identify asbestos simply by looking at it. Before conducting any remodeling, you should hire a professional to conduct a survey of possible asbestos-containing materials in your home. To be safe, treat all suspect materials as if they contain asbestos until you get samples analyzed. You should confirm the presence of asbestos by having suspect materials analyzed by a laboratory.
You can find asbestos professionals in the yellow pages or a web search. An accredited asbestos inspector will have completed training and received accreditation through an EPA approved program under the Model Accreditation Program training rules in 40 CFR Part 763.
DEQ strongly recommends that a professional asbestos inspector take samples and send them to a laboratory for analysis. However, if you are the home owner and this is your residence, then you can take a sample yourself. This does not apply when demolition activity is to occur at the residence. To avoid exposing anyone else, only you should be in the room when taking samples.
- Wet down the material with a light water mist before taking the sample. This reduces the potential release of asbestos fibers.
- Do not disturb the material any more than is necessary to take a small sample.
- Place the sample in a clean, air-tight container such as a zip-lock bag or small glass jar. Seal tightly.
- Use a damp paper towel to clean up any material on the outside of the container or that might have spilled onto the floor.
- Clearly label the container, stating where and when the sample was taken.
- Send the sample to a laboratory for analyses. Make sure to take one sample for each different type of suspect material.
- Find a laboratory
If the asbestos-containing material is NOT broken, worn, damaged or disturbed, it poses little or no danger. Asbestos removal involves disturbing the material and possibly releasing asbestos into the air. Leaving asbestos containing material intact is often a safer option.
DEQ strongly recommends against repairing or removing asbestos-containing materials yourself. Removing asbestos properly requires special equipment and detailed training. An individual could cause asbestos fiber contamination throughout your home and neighborhood, exposing your family and others unknowingly. DEQ recommends you hire a licensed asbestos abatement contractor to ensure that the work is done properly.
However, the regulations allow for you to repair or remove asbestos in a house that you own and live in. If you do your own asbestos removal work, you are responsible for following all handling, transport and disposal regulations. Asbestos-containing waste requires special handling and disposal and must be disposed of at a landfill permitted to accept asbestos waste.
DEQ issues licenses to contractors that meet the requirements of Oregon's asbestos program. Make sure the contractor you hire appears on DEQ's list of Licensed Asbestos Abatement Contractors
. Hiring a licensed contractor ensures they have the knowledge to properly remove asbestos-containing materials, use safety equipment, have received specialized training, and their employees and supervisors are certified.
As part of obtaining a license from DEQ, contractors are required to submit the information described below. You should feel free to request this information from contractors to assist you in your selection.
- Registration with the Oregon Construction Contractors Board.
- Registration with the Oregon Business Registry Section of the Corporations Division.
- A list of certified workers and supervisors employed by the company.
- A list of asbestos abatement projects conducted in the prior year.
- A list of all asbestos-related enforcement actions taken against the company.
The following is not required, but would give you added confidence that a contractor is capable of conducting an asbestos abatement project properly:
- A list of all equipment that will be used for asbestos work. That list should include negative air machines, HEPA vacuums, type of respiration equipment they will use, scaffolding, decontamination facilities, disposable clothing.
- Written standard operating procedures and employee protection plans which include specific reference to Oregon OSHA medical monitoring and respirator training programs.
- Air sampling results from previous projects.
- References from previous clients.
There's a good chance you can solve the problems without actually removing the asbestos. Removal is generally the last resort because it involves disturbing the material and releasing more asbestos fibers into the air. In attempting a repair job, you should take a common sense approach to protecting yourself from possible exposure to asbestos fibers. We recommend wearing eye protection and a respirator to minimize breathing in fibers, and protective clothing to minimize further contamination.
- Repairing pipe, furnace and boiler insulation: If the material is moves at the touch or the cover no longer feels firm, the insulation is probably too deteriorated for repair. DEQ recommends you call a Licensed Asbestos Abatement Contractor.
If the insulation is firm and the cover is tight, with very few holes or tears in the insulation (no more than one hole every 1-3 feet of pipe covering) you can consider repairing it yourself. Use a commercial product specifically designed to fill holes and seal damaged areas in asbestos pipe insulation. You can find them at safety supply stores that specialize in selling asbestos-removal products.
- Repairing sprayed-on asbestos-containing walls and ceilings: If the material has never been painted, a coat of penetrating or bridging encapsulant can be sprayed on with an airless sprayer to seal the surface. Do not use a brush or roller. Note: Encapsulant soaks into the wall or ceiling material and firmly adheres it to the sub-surface, making future removal more difficult.
Some commonly found non-friable asbestos-containing materials can be removed relatively safely. You can perform the removal of nonfriable materials yourself or hire a licensed asbestos abatement contractor. These documents offer guidelines on how to remove specific materials safely:
Guidance on how to remove friable asbestos-containing material (popcorn texture, furnace insulation, sheet vinyl and homeowner survey) is available to a homeowner who lives at the residence and would like to perform the removal themselves by contacting DEQ asbestos staff
. This is not
recommended, but allowed.
If you think a significant amount of asbestos has been released in your home:
- Close off the part of the home where the release occurred.
- Close off air ducts and vents.
- Shut windows.
- Tape bottoms of doors to prevent draft.
- Contact a licensed asbestos abatement contractor or DEQ for information on what to do next.
Health impacts that are typically associated with being exposed to asbestos comes primarily from working for long periods of time around very high concentrations of fibers. Your health should not be impacted by a single exposure to asbestos fibers, but if you are concerned, please consult your doctor.
All asbestos-containing waste materials, including all wastes contaminated with asbestos, such as all disposable clothing, respirator filters, safety equipment, materials used for containment, and materials used to clean up the area must be disposed of properly. All waste materials must be placed in double 6 mil plastic bags, labeled as asbestos, and hauled to a landfill approved to accept asbestos.
