Which of the following activities can damage friable asbestos materials?

The correct choice highlights that air movement, maintenance activities, and vibration from machinery can damage friable asbestos materials. Friable asbestos refers to any asbestos-containing material that can be easily crumbled by hand pressure and can release asbestos fibers into the air when disturbed.

Air movement can disperse asbestos fibers, increasing the risk of inhalation. Maintenance activities often involve the manipulation or handling of materials that may be made of or contain friable asbestos, which can lead to fiber release if the materials are damaged. Similarly, vibrations from machinery can disturb these materials, causing them to break apart and release dangerous fibers.

In contrast, water application can sometimes be used as a precautionary measure to suppress dust and prevent fiber release. Wrapping friable materials in plastic could be a method to contain them and reduce exposure, and regular cleaning, if done properly with appropriate methods and protective equipment, would typically aim to minimize the risks associated with asbestos exposure rather than cause damage.
