If you’re planning a renovation or interior demolition in an older building, it’s crucial to arrange for a hazmat inspection before beginning your project. This can help identify hazardous materials, such as asbestos, which is frequently found in older structures.
The issue with materials containing asbestos is the health risks they present. While the mere presence of asbestos isn’t immediately harmful, it becomes dangerous when disturbed. Airborne exposure can lead to serious health conditions, including lung scarring and various cancers associated with asbestos.
Below are some of the most common materials found in buildings that may contain asbestos:
Transite Cement
Transite cement, often referred to as asbestos cement, is a composite made from cement and asbestos fibers. These fibers are shaped into products such as walls and piping.
In Canada, asbestos cement pipes were used for drinking water distribution until the early 1980s. Many of these pipes remain in service in various water systems across the country. However, ingesting asbestos is considered less risky than inhaling it.
Fireproofing Insulation
Fire-retardant insulation was widely used in buildings constructed before the 1990s due to its fire-resistant properties, as asbestos is nonflammable and noncombustible, with a melting point of approximately 1,600 degrees Fahrenheit. It is also an excellent thermal and electrical insulator.
Floor Tiles
Vinyl tiles manufactured in the 1970s and 1980s often contained asbestos due to its durability. Older buildings that have not replaced their flooring may still have asbestos-laden tiles.
Adhesives
Asbestos was frequently added to various adhesives to enhance their strength. It can be found in products such as grout, sealants, putties, and dry powder mixes. One common adhesive containing asbestos is asphaltic cutback, which is a black adhesive used beneath vinyl tiles and flooring.
Roofing Materials
Asbestos is also found in roofing materials, thanks to its durability and fireproofing properties. Damage from severe weather can release asbestos particles into the air, making routine inspections essential.
Textured Coatings
Spray-on coatings, like popcorn ceilings, are another common source of asbestos in buildings. Asbestos was incorporated for fire-retardant purposes and to improve soundproofing.
Rope Seals and Gaskets
Asbestos is often present in rope seals and gaskets used around gas or electric heating appliances due to its fireproof characteristics and low heat transfer rate. However, attempting to replace these appliances without proper precautions can lead to exposure.
Schedule an Asbestos Hazmat Inspection
If you plan to renovate an older building, conducting an asbestos inspection is crucial. Given the widespread use of asbestos for its durability, fire resistance, and soundproofing qualities, it’s likely to be present in structures built before the 1990s. Protect your health by investing in asbestos testing to avoid respiratory issues or lung diseases.
