What is the consequence of using compressed air to blow away asbestos dust?

Answer: B — It can spread harmful fibers

Using compressed air to blow away asbestos dust can indeed spread harmful fibers into the air, creating a significant health risk. Asbestos fibers are microscopic and can easily become airborne when disturbed. When compressed air is used, it can dislodge and lift these dangerous particles, allowing them to circulate in the environment where they can be inhaled by individuals present. This is particularly concerning because inhalation of asbestos fibers can lead to serious respiratory diseases, including asbestosis, lung cancer, and mesothelioma. The other options do not accurately reflect the safety and efficacy of this method. While it may seem like a quick way to remove dust, the consequences far outweigh any perceived efficiency. Safety standards and best practices typically recommend using wet methods or specialized vacuums designed for asbestos removal instead of compressed air to minimize the risk of fiber dissemination.
