Percolation Tests FAQs, answered by experts

Typical methods for asbestos removal include encapsulation, enclosure, and complete removal.

According to the National Cancer Institute, asbestos-related diseases can take anywhere from 10 to 40 years for symptoms to appear. The health risks increase with prolonged and heavier exposure. Risk factors also include:

Amount of exposure
Chemical makeup, size, and shape of the asbestos fibers
Length of time a person is exposed to asbestos
Genetic factors
Source of exposure (direct exposure or secondhand exposure from someone directly exposed)

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

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

Do not panic if you are exposed to asbestos. The illnesses associated with asbestos exposure are rare. If you are concerned about exposure, talk to your doctor, especially if you are having any respiratory symptoms, such as coughing or difficulty breathing. They may recommend imaging to get a view of the insides of your organs and determine if scarring or growths are present.
