Asbestos, a naturally occurring mineral, was widely used in a variety of materials in the construction of homes during the 20th century. Today, we know that exposure to asbestos can lead to serious health problems, including lung cancer and mesothelioma. If you are living in an older home, it’s essential to be aware of potential asbestos-containing materials (ACMs) and take the necessary steps to manage or remove them. This article will guide you through some key points you should look for and how to identify possible ACMs.
What to Look For
Asbestos was commonly used because of its durability and fire-resistant properties. Here are some typical places it might be found in your home:
- Insulation: Asbestos was often used for thermal insulation in attics and wall spaces, as well as around boilers, ducts, pipes, sheeting, fireplaces, and stoves.
- Flooring and Ceilings: Vinyl asbestos tiles were a popular choice for flooring and ceiling tiles because of their strength and resistance to heat. Additionally, popcorn ceilings, a common feature in homes between the 1950s and the 1980s, may also contain asbestos. Popcorn ceilings have a distinctive, bumpy texture resembling popcorn or cottage cheese.
- Roofing and Siding: Asbestos cement, also known as “CAB” siding, was used in roofing, siding, and around windows because of its weather-resistant properties. CAB siding often has a wavy or straight-lined pattern and is usually grey or white.
- Textured Paint and Patching Compounds: Certain textured paints and patching compounds used on wall and ceiling joints may contain asbestos. Popcorn ceilings commonly contain asbestos.
- Undercoating on Sinks: Older sinks may have an asbestos-containing undercoating, usually a grey or off-white compound applied for noise reduction and insulation.
Identifying Asbestos-Containing Materials
Asbestos cannot be identified by sight alone. However, certain physical characteristics can suggest its presence:
- Age of the House: If your house was built between the 1930s and 1980s, there’s a higher chance it contains asbestos.
- Physical Appearance: Asbestos can sometimes be identified by certain physical properties. Look for:
- Pipe Wrap Insulation: This may look like a white or grey paper-like material wrapped around older pipes, sometimes with a canvas-like wrapping on top.
- Vermiculite: Vermiculite is a pebble-like, pour-in product that is usually gray-brown or silver-gold in color. It was commonly used as insulation in attics.
- Vinyl Floor Tiles: These are often square (9-inch or 12-inch) and could be a variety of colors. They may have a shine or a patterned or marbled appearance.
- CAB Siding: Asbestos cement or “CAB” siding often has a wavy or straight-lined pattern and is typically grey or white.
- Hidden Layers: Sometimes, older vinyl flooring, which can contain asbestos, lies beneath carpets or wooden floors. Check for this by lifting your floor air vent cover. If you find multiple layers, it’s possible that asbestos-containing materials are present.
Remember, if you suspect that materials in your home contain asbestos, do not disturb them. Disturbing ACMs can release asbestos fibers into the air, increasing the risk of exposure.
Professional Help
If you believe your home may have asbestos-containing materials, the safest approach is to seek help from a professional asbestos inspector. They can take samples for lab testing and provide guidance on managing or removing any asbestos found.
