Asbestos, a naturally occurring mineral, was once widely used in construction materials due to its heat-resistant and insulating properties.
Situations in which a person can encounter asbestos in a residential rental or commercial unit can vary.
Older Buildings
Asbestos was widely used in construction materials until the late 20th century, so residential and commercial properties built before the 1980s are more likely to contain asbestos.
This includes buildings constructed for housing, offices, retail spaces, warehouses, and industrial facilities.
Renovation or Repair Work
When renovations or repairs are conducted in older properties, it can disturb asbestos-containing materials.
Removing walls, ceilings, flooring, or insulation can release asbestos fibers into the air, posing a risk to occupants, contractors, and workers.
Deterioration of Materials
Over time, asbestos-containing materials can deteriorate naturally or due to water damage, aging, or mechanical stress.
As the materials degrade, asbestos fibers can become friable (easily crumbled) and be released into the air, increasing the potential for exposure.
Insulation
Asbestos was commonly used for insulation purposes, including pipe insulation, HVAC systems, and boiler rooms.
Residential rentals and commercial units with older insulation systems may still contain asbestos.
Ceiling Tiles and Flooring
Some ceiling tiles and flooring materials, particularly those manufactured before the 1980s, may contain asbestos.
Asbestos fibers can be released into the air when these materials are disturbed or damaged.
Vermiculite Attic Insulation
Vermiculite insulation, often found in older homes, may contain asbestos.
It was commonly used as attic insulation but can pose a risk if disturbed during maintenance or renovations.
Popcorn Ceiling
Popcorn or textured ceilings, popular from the 1950s to the 1980s, frequently contain asbestos.
Sanding, scraping, or disturbing these ceilings can release asbestos fibers into the air.
Asbestos-Containing Products
Asbestos was used in various products, including adhesives, sealants, paints, caulking, and roofing materials.
In some cases, these products may still be present in residential rentals and commercial units, posing a risk if disturbed or deteriorated.
