Asbestos Abatement Basics

Before removal begins, abatement crews seal off the work area with plastic sheeting and barriers. They often use negative air pressure machines with HEPA filters, which pull air through filters and prevent fibers from escaping into other areas. Entry and exit usually pass through a decontamination unit where workers remove protective clothing and shower. Warning signs mark the area. These steps keep fibers inside the work zone and away from people who are not protected. Well-run projects also plan ventilation and access routes carefully so the containment stays intact throughout the job.

Workers keep asbestos materials wet during removal to reduce airborne fibers. They remove materials in as large pieces as possible, avoiding power tools that create dust. Debris is bagged in heavy, labeled containers and transported to approved disposal sites. Workers wear respirators and disposable suits suited to the job. In some cases, encapsulation or enclosure, which seals or covers the material, is chosen instead of removal. The right approach depends on the material's condition, location and planned use of the space. Crews should also protect surfaces that stay in place.

After removal, the area is cleaned and inspected. Air clearance testing, often performed by an independent consultant, confirms fiber levels are acceptably low before containment is removed. Federal and state rules may require advance notice to regulators for larger projects, and waste must be tracked from the site to disposal. Owners should keep copies of the contract, notification forms, air test results and disposal records. These documents show that the work was done properly and can be important for future renovations or property sales. Ask for them before final payment.

1. 1

   Hire a contractor licensed for asbestos abatement in your state.

2. 2

   Ask whether an independent consultant will perform air clearance testing.

3. 3

   Confirm that required regulatory notifications will be filed before work starts.

4. 4

   Keep all contracts, air test results and disposal records after the project.
