When is asbestos hazardous

If it is left alone and not disturbed, it will not. Asbestos pipe and boiler insulation does not present a hazard unless the protective canvas covering is cut or damaged in such a way that the asbestos underneath is actually exposed to the air. Damage and deterioration will increase the friability of asbestos-containing materials.

If you live in an older home, do a visual check of all your hot water pipes and furnace air ducts. Look to see if the potentially asbestos-containing insulation material is breaking or coming apart. If it is breaking or coming apart, do not disturb it. This may create more asbestos dust that can spread in your home. Keep people and pets away, and consult with an asbestos removal expert before you attempt to remove or seal the material. Some forms of insulation may look like asbestos, but they are actually mineral or fibreglass-based insulation materials that are unlikely to pose a health risk.

To reduce your risk of exposure to asbestos, it is always best to hire a professional to collect and test a sample of the material for asbestos. If you are renovating an older house, be alert to unexpected sources of asbestos.

Get a professional opinion before starting the renovation and hire a professional to conduct the removal. Power sanding floor tiles, plaster walls or partitions made partly from asbestos can release dangerous quantities of inhalable fibres into the air. To find a professional who can test a sample of your material for asbestos, see Directory of Qualified Laboratories in BC www. These contractors use specialized and personal protective equipment and professional methods for removing asbestos dust and disposing of the material safely.

CERCLA authority may be appropriate to respond to the release or potential release of asbestos into the environment. Persons subject to the rule are required to notify EPA at least 90 days before commencing any manufacturing, importing, or processing of asbestos or asbestos-containing products covered under the rule.

These uses are prohibited until EPA conducts a thorough review of the notice and puts in place any necessary restrictions or prohibits use. Asbestos-Containing Materials in Schools Rule Pursuant to the Asbestos Hazard Emergency Response Act AHERA , the Asbestos-Containing Materials in Schools rule requires local education agencies to inspect their school buildings for asbestos-containing building material, prepare asbestos management plans and perform asbestos response actions to prevent or reduce asbestos hazards.

In , this regulation was overturned by the Fifth Circuit Court of Appeals. However, as a result of the Court's decision, only a few asbestos-containing products remain banned.

The regulations require the owner of the building or the operator to notify the appropriate state agency before any demolition, or before any renovations of buildings that could contain a certain threshold amount of asbestos or asbestos-containing material.

However, anyone exposed to asbestos has a higher risk of getting an asbestos disease. All of the asbestos diseases are difficult to treat. Most are impossible to cure. Stopping asbestos fibers from ever entering your lungs is important.

The only cure for most asbestos diseases is to prevent them. The most common test used to learn if you have been exposed to asbestos is a chest x-ray. The x-ray cannot detect the asbestos fibers themselves, but can detect early signs of lung disease caused by asbestos. Other tests, such as lung scanning and computer-aided tomography CAT scan , are also useful in detecting changes in the lungs.

Asbestos is dangerous because it has the ability to break down into microscopically thin fibers. These fibers are so small they can remain airborne for days after they were initially disturbed.
