How should friable asbestos removed from elevated heights be transported to the ground?

When dealing with friable asbestos, safety is of utmost importance due to the material's hazardous nature when disturbed. The correct answer emphasizes the need for extreme caution throughout the transportation process. Friable asbestos can easily release dangerous asbestos fibers into the air, which can pose health risks if inhaled.

Transporting friable asbestos with extreme caution involves using proper containment methods and protective gear, ensuring that the material is secured and won’t be disturbed further during movement. This also entails following regulatory guidelines and utilizing appropriate equipment designed for safe handling.

The other options include methods that could compromise safety. For instance, dropping or throwing the asbestos can lead to the release of fibers and create a hazardous environment. Additionally, using a crane, while it might seem practical, generally isn't appropriate for safely transporting friable asbestos without the proper containment measures. Thus, the emphasis on extreme caution is crucial in mitigating risks associated with asbestos handling and adhering to safety protocols.
