Percolation Tests questions, answered by experts

Asbestos-containing materials are not easily affected by water and do not disintegrate or dissolve when exposed to it. However, porous materials can deteriorate due to water exposure, leading to the release of asbestos fibers into the air. The settling of asbestos fibers can also occur as water makes them heavy, which reduces the risk of airborne exposure, though future disturbance of the materials could cause risk. Wetting asbestos-containing materials does not constitute safe removal, and the proper handling and disposal of asbestos materials should be left to professionals.

Asbestos can be found in many building materials, especially if the materials were installed more than 20 years ago. Asbestos-containing materials (ACM) can include:

Acoustic ceiling tiles
Furnace insulation
Home appliances
Fire-retardant clothing
Cement pipe
Pipe insulation
Wall and ceiling insulation
Vehicle brake pads
Vinyl flooring
Sprayed acoustic ceilings
Stove insulation
Patching compounds
Textured paints
Roofing shingles
Siding

Research a home’s history to determine the time period when it was built and any renovations made since.

No, but it’s common that they do. Gravity furnaces weren’t terribly efficient so wrapping either the ductwork in asbestos, the furnace itself, or both, was something done regularly. This allowed the system to retain more heat. At the time, this greatly enhanced the efficiency of the furnaces but it wasn’t until later that we became aware of just how carcinogenic and dangerous asbestos could be.

Damaged tiles can release asbestos fibers into the air. Anyone in the surrounding area who may inhale the fibers will have them settled in the lining of internal organs. Over time, it may lead to serious health conditions such as lung cancer and mesothelioma.

The only safe way to prevent these conditions is to avoid exposure to asbestos at all costs, even for a short period of time.
