The incorrect technique for minimizing fiber release is using low-speed fans to disperse fibers, as it increases the spread of asbestos. The correct answer is (b).
The technique that is not considered a proper method for minimizing fiber release is using low-speed fans to disperse fibers. Using low-speed fans would likely spread the fibers through the air rather than contain them. Proper techniques for minimizing the release of asbestos fibers include wetting surfaces with water to reduce airborne fibers, encapsulating asbestos-containing materials to prevent releasing fibers, and using proper personal protective equipment (PPE) to protect individuals from inhaling fibers. These methods align with health guidelines to mitigate the dangers associated with asbestos exposure, including lung cancer, mesothelioma, and asbestosis.
So, the correct answer is (b) Using low-speed fans to disperse fibers, as this method exacerbates the spread of asbestos fibers rather than containing or minimizing them.
