Which method is commonly used to control exposure to asbestos during removal?

Using wet methods to control exposure to asbestos during removal is effective because it helps to suppress dust generation, which is a key concern when handling this hazardous material. Wetting the asbestos-containing material before it is disturbed or removed minimizes the likelihood of airborne particles, thereby reducing the risk of inhalation and exposure for workers and others in the vicinity.

When wet methods are employed, water is typically used to saturate the material, which helps to bind the fibers and keep them from becoming airborne. This is in line with safety regulations and best practices established for asbestos abatement work, where controlling the environment is crucial to protecting health and safety.

Other methods listed, such as dry sweeping, can exacerbate the problem by kicking up more dust and fibers into the air, increasing exposure risk. Using air fresheners does not address the issue of airborne asbestos fibers and is ineffective as an exposure control measure. Evacuating the site temporarily might help in the short term but does not actively mitigate the risk during the removal process itself. Wet methods provide a direct and proactive approach to managing asbestos safely.
