Which of the following is not part of a hoisting safety check?

Cleaning the equipment is not typically categorized as part of a hoisting safety check. The primary aim of a hoisting safety check is to ensure that the equipment and procedures are in optimal condition to prevent accidents and ensure safety during lifting operations.

When inspecting the lifting equipment, one must examine the condition and functionality of hoisting gear such as hooks, chains, cables, and the hoist mechanism itself. This ensures that everything is in proper working order and free from defects.

Checking the load distribution is crucial as it ensures that the weight of the load is balanced and within the lifting capacity of the hoisting equipment. Proper load distribution helps to prevent tipping or swaying during lifting, which can lead to accidents.

Verifying the signal person's instructions is also essential for safety. The signal person communicates vital information to the operator to ensure that lifting operations proceed smoothly and safely. This communication helps to prevent errors that could result in injury or damage.

In summary, while cleaning the equipment is important for maintenance, it does not directly relate to the safety checks required before hoisting operations, making it the correct answer.
