Percolation Tests FAQs, answered by experts

If you think you’ve touched asbestos, do not put on a mask. This is important because you may take the asbestos fibers on your hands on trap them in the mask. Make your way to a sink and wash your hands thoroughly. Remove any clothes and seal them in a bag, then take a shower. Call your doctor and let them know you’ve been exposed to asbestos, and make sure you see them as soon as possible. The reason you keep the clothes is in case anyone wants to confirm the presence of asbestos.

Clear the area for access and inform the testing team about the building’s history and renovations.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

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.
