What potential hazard can occur from falling ice off the boom?

Falling ice from the boom poses a significant hazard, primarily through the potential to cause injury to workers positioned below. When ice accumulates on the boom, it can become dislodged due to vibrations, temperature changes, or other movements of the crane. If this ice falls, it can fall with enough force to cause serious injuries, ranging from impact injuries to possible fatalities, depending on the size and weight of the ice, as well as the height from which it falls.

Ensuring the safety of workers is critical on any job site, and awareness of potential hazards like falling ice is a fundamental part of this responsibility. Safety protocols often include measures for inspecting and clearing the boom before operation, especially in colder climates where ice might be a concern. The other options do not accurately reflect the realities of operating hoisting equipment in potentially hazardous conditions.
