Giải thích
Older buildings may contain asbestos in flooring, mastic, insulation, and similar materials. The BEST practice is to survey or test suspect materials and, if asbestos is confirmed, use a registered/certified asbestos abatement contractor with proper containment, wet methods, and disposal. Option d reflects this. Cutting (a) and dry sweeping (b) release fibers, and assuming materials are asbestos-free (c) risks unlawful, hazardous exposure.
