In one sentence, describe what the following article is about:

Repairs to materials that contain asbestos usually involved either sealing or covering the area to prevent fibers from being released into the air. With such a dangerous carcinogen present, it might seem strange to repair it instead of removing it, but repair is actually the safest option. Removing the materials tends to disturb them more, posing a greater health risk, while repairing the materials to contain the asbestos allows you to live with the materials safely.  Repairs should be conducted by a certified professional to ensure they are done properly. In most cases, a special sealant or covering is applied to the area to keep it from breaking down. Floors containing asbestos might be covered with new flooring to keep fibers from entering the air. Repairs are less expensive than removal, and usually the best all-around option. However, if the materials are already quite damaged, and they'll eventually need to be removed, it's better to spring for removal right away. Applying a sealant or covering can make it more difficult to remove the materials later. After repairs have been conducted, it's still important to be careful around the materials that contain asbestos. Be cautious around the materials in question so you don't end up disturbing them and releasing the asbestos fibers. Take the following measures to live safely with asbestos:  Keep activities to a minimum in the areas that have asbestos. For example, if the walls in your basement contain asbestos, don't spend more time than necessary there.  Don't saw, sand, scrape, drill, or otherwise damage materials that contain asbestos, even after sealant has been applied. Don't use abrasive cleaning materials on materials that have asbestos. Don't vacuum or sweep debris on the floor that might contain asbestos. If further damage occurs, have it repaired by a professional. If you'd simply prefer not to have asbestos-containing materials in the building, you can opt for removal instead of repair. Hire a contractor who has been trained by the EPA. The removal process is more dangerous than the repair process, and if done improperly it can pose a serious health risk to individuals using the building.

Summary:
Have the disturbed material repaired. Live safely with materials that contain asbestos. Consider asbestos removal.
