What must be done to minimize dust during the handling of asbestos materials?

Minimizing dust during the handling of asbestos materials is crucial for protecting health and safety. Using water to dampen materials serves as an effective method because it helps to minimize airborne particles that can result from disturbing asbestos. When asbestos is wet, the fibers are less likely to become airborne, greatly reducing the risk of inhalation exposure during handling, removal, or demolition activities.

The other strategies may not be as effective or could have their own limitations. Covering materials at all times can help, but it does not address the dust reduction while handling. Applying strong adhesive may control dust momentarily, yet it does not offer the same direct and immediate effect as dampening. Isolating the area completely could prevent exposure to others, but without addressing the dust itself during handling, it may not sufficiently protect those involved in the asbestos work. Thus, dampening materials with water is the most effective approach among the options for managing dust during asbestos handling.
