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.

According to the Environmental Protection Agency (EPA), you should contact the following officials to report a case of asbestos exposure:

Asbestos subject matter experts in your state
EPA regional office
Toxic Substances Control Act (TSCA) Assistance Information Service Hotline via mail, email, or phone
EPA’s Asbestos Ombudsman via phone or fax

No, an N95 mask will not protect against asbestos and many other hazardous materials, such as carbon monoxide, gas, chemical vapors, and other gases. You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, hire an asbestos abatement professional immediately and avoid the area until they arrive for the inspection.
