As a naturally occurring mineral, asbestos possesses unique physical and chemical properties. Not only is it highly durable and heat-resistant but its ability to insulate is unsurpassed by any other substance on Earth including rock wool or fiberglass insulation.
During most of the 20th century, these characteristics made asbestos the material of choice for a wide variety of uses.
Unfortunately, the very properties that made asbestos useful–its heat resistance and insulation potential–add danger. When fibers are inhaled, they can cause serious health problems including mesothelioma (a rare form of cancer that attacks tissue linings), lung cancer and asbestosis.
Asbestos products came into widespread use during the latter part of the 19th century and only declined after its harmful effects on health became known in the late 20th century.
Nevertheless, asbestos was used in thousands of products: from domestic gadgets to heavy machinery. Recognizing which products contain asbestos and what their risks are is vital for anyone involved in renovation, construction or works in industry. This guide provides a comprehensive overview of products that contain asbestos, and their uses as well as the associated risks.
What is Asbestos and Why Was It Used?
Asbestos is a fibrous silicate mineral. These inorganic minerals that are strong like rock but light as cork yet harder than steel on the Mohs scale can have hair-thin crystals producing its most common form–serpentine asbestos. Of the six varieties found in nature today (chrysotile, amosite, crocidolite, tremolite, anthophyllite and actinolite), none is affected by heat, fire or chemicals and all are non-conductors of electricity. Thanks to these properties asbestos soon proved itself as an ideal material for many different applications.
Historically, chrysotile asbestos was used in buildings materials, automotive parts, and even everyday products such as consumer goods. Particularly valued in industries with high ‘imaginable’ temperatures because of its fire-resistant and insulating properties means that asbestos was used for many things. For example, asbestos was used in:
- Block insulation for pipes and boilers
- Fireproofing materials
- Brake linings in vehicles
Asbestos’s advantages led to its extensive usage in all kinds of industries. Nevertheless, the health risks of asbestos exposure were not fully recognized until the second half of the 20th century. By then, millions of people had come into contact with asbestos fibers, resulting in a major public health disaster.
Common Products Containing Asbestos
Because of its insulating and fireproof nature, asbestos was a familiar sight in the home. Some of the most popular items in which asbestos can be found are:
- Insulation: Asbestos is widely used in home insulation, particularly in older homes. This includes pipe insulation, attic insulation, and wall insulation.
- Ceiling Tiles: Many homes built before the 1980s have ceiling tiles that contain asbestos. These tiles were popular because they were fire-resistant and provided good sound insulation.
- Floor Tiles: Asbestos was used in vinyl floor tiles and the adhesive that holds them in place. These tiles are durable and resistant to heat and chemicals.
- Roofing Materials: Asbestos was used in roofing shingles, felt, and tar paper. These materials are durable and resistant to weathering and fire.
- Textured Paints and Coatings: Some older homes have textured paints and coatings that contain asbestos. These were used to create decorative finishes on walls and ceilings.
High-Risk Asbestos Products
Certain asbestos-containing products pose a higher risk due to their friability—the ability to crumble and release fibers into the air. High-risk products include:
- Spray-On Insulation: This type of insulation was commonly used in buildings for fireproofing and soundproofing. It is highly friable and can easily release asbestos fibers when disturbed.
- Pipe Lagging: Asbestos material was used to insulate pipes in industrial and residential settings. Over time, this insulation can deteriorate and release fibers.
- Boiler Insulation: Boilers were often insulated with asbestos to prevent heat loss and protect against fire. This insulation can become friable and release fibers, especially during maintenance.
The danger of these products lies in their friability:
- Friable Asbestos: This type of asbestos can be easily crumbled or reduced to powder by hand pressure. Examples include spray-on insulation and pipe lagging. Friable asbestos is particularly dangerous because it can release fibers into the air with minimal disturbance.
- Non-Friable Asbestos: This type of asbestos is bound in a solid matrix and is less likely to release fibers. Examples include asbestos cement sheets and floor tiles. Non-friable asbestos is generally considered less dangerous, but it can still pose a risk if it is cut, sanded, or otherwise disturbed.
The risks associated with deteriorating or damaged asbestos products are significant. As these materials age, they can become more friable and more likely to release fibers. This is why it is crucial to handle asbestos-containing materials with care and to follow proper safety protocols during removal or repair.
Asbestos in Consumer Goods
Yes, consumer goods can still contain asbestos, although its use has significantly declined due to health risks. Historically, asbestos was used in a variety of products for its heat resistance and durability. Examples include:
- Hair dryers
- Toasters
- Irons
Even today, some imported products might contain asbestos, such as:
- Children’s toys
- Crayons
- Makeup
Current regulations aim to protect consumers. In the U.S., the Environmental Protection Agency (EPA) and the Consumer Product Safety Commission (CPSC) enforce strict guidelines. Products must undergo rigorous safety checks to ensure they are asbestos-free. However, gaps in regulation and enforcement can still pose risks.
Exposure risks from the daily use of items containing asbestos are significant. Asbestos fibers can become airborne and inhaled, leading to serious health issues like mesothelioma, lung cancer, and asbestosis. Even minimal exposure can be dangerous over time, making it crucial to avoid products with potential asbestos content.
