Percolation Tests questions, answered by experts

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

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.

Often found in old insulation, tiles, and roofing materials in pre-1980s buildings.

Regulations require certified professionals for removals and disposal in compliance with local and federal guidelines, ensuring safety and legality.

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.
