The Hazards of Asbestos in Older Homes

Asbestos remains a crucial topic for homeowners, especially as the demand for renovation and remodeling continues to grow. It's common for families to ignore the potential hazards of using outdated building materials when they want to update their living areas or increase energy efficiency. Asbestos-containing materials (ACM) may unintentionally be disturbed by home renovations, releasing hazardous fibers into the atmosphere.

Understanding the Hazards of Asbestos Exposure

Ignoring the potential for ACM while renovating is a risk to the health of your family. Asbestos disturbance has serious and frequently delayed repercussions. These tiny threads can cause severe, potentially fatal illnesses if inhaled.

• Lung Diseases: Inhalation of asbestos fibers can lead to serious respiratory disorders, including asbestosis, a chronic lung disease that causes scarring of lung tissue.
• Mesothelioma: An uncommon and deadly cancer that attacks the lining of the heart, abdomen, or lungs, mesothelioma is mostly caused by asbestos exposure.
• Lung Cancer: Exposure to asbestos is linked to an increased risk of lung cancer, particularly in smokers, where the risk is markedly elevated.
• Pleural Thickening: Breathing problems and chest pain may result from asbestos-induced thickening of the pleura, the membrane that surrounds the lungs.

It's important to understand that asbestos-related disease symptoms can take decades to manifest, making early diagnosis and prevention difficult—which explains why preventive inspection is so vital.

Typical Asbestos Signs and Locations in Your Home

Asbestos is normally safe when left undisturbed, but when it is damaged, disturbed, or starts to decay, there is a risk. The age and location of the construction materials are the main "signs":

• Age of the Property: There's a good chance that some of the components in your house contain asbestos if it was constructed before 1980.
• Insulation: One typical source is friable (crumbly) insulation found in basements or attics, especially vermiculite insulation.
• Pipe and Duct Wrapping: Asbestos is frequently found in corrugated or smooth paper-like wrapping or cement-like insulation surrounding boilers, furnace ducts, and hot water pipes.
• Flooring: Before the 1980s, asbestos was often present in nine-by-nine-inch (9"x9") vinyl floor tiles and the mastic used to place them.
• Siding and Roofing: Asbestos cement, which is normally nonfriable (solid) but can release fibers if cut or sanded, is used in cement siding shingles and some roofing materials.
• Textured Paints and Ceiling Finishes: Asbestos is frequently present in popcorn ceilings built prior to the late 1970s.
• Wall Materials: Asbestos may be present in some types of ancient plaster and joint compound used on drywall joints.

Damage is the most alarming indication. Until they are tested, any of these suspected materials should be regarded as dangerous if they are cracked, crumbling, peeling, or water damaged. Never try to remove, drill, sand, or cut these materials yourself.
