Final answer:
A safe work practice when using a crane to move a load is to lower the load to the ground first before stepping away. This ensures stability and reduces the risk of accidents.
Step-by-step explanation:
A safe work practice when using a crane to move a load is to lower the load to the ground first before stepping away. This ensures that the load is stable and not suspended in the air, reducing the risk of accidents. It is important to lower the load carefully and secure it properly before leaving the crane unattended.
Raising the load quickly (option B) is not a safe practice as it can lead to instability and potential accidents. Maintaining a clear view of the raised load (option A) is important, but if multitasking is necessary, it's safer to lower the load first before attending to other tasks. Raising the load high enough to clear people walking underneath (option D) is also a safety requirement to prevent any potential injuries.
