What is the main purpose of using wet methods during asbestos work?

• A. To minimize fiber release
• B. To improve visibility
• C. To increase fiber dispersion
• D. To shorten work time

Answer: (A)

Keeping materials wet during asbestos work is used to suppress dust and prevent fibers from becoming airborne. Water adds moisture that makes fibers cling together and settle rather than float in the air, which keeps the air clearer and makes containment easier. This directly reduces the risk of inhaling dangerous fibers for workers and others nearby, which is the main goal of using wet methods. While moisture can sometimes help with visibility by reducing dust, and dampening can affect workflow, those are side effects. Wetting primarily works to minimize fiber release, not to increase dispersion or shorten the job.
