Which of the following is a key safety practice for operating heavy equipment?

Performing a pre-operational inspection before using heavy equipment is a critical safety practice. This inspection involves checking various aspects of the equipment to ensure it is safe to operate, including assessing fluid levels, brakes, lights, and safety features. By conducting this thorough examination, operators can identify any potential issues or hazards that could lead to accidents or malfunctions during operation. This proactive measure helps ensure the safety of the operator and those working in the vicinity, thereby minimizing risks associated with equipment failure.

High-visibility clothing, while important for improving visibility and safety around moving machinery, is not as foundational as ensuring the equipment itself is functioning properly. Conducting random inspections may not provide the structured and consistent safety checks necessary to identify issues before operation. Using machines without maintenance checks introduces significant risk, as it could lead to serious accidents due to equipment failure. Hence, the practice of performing a pre-operational inspection stands out as essential for safe operations in heavy equipment use.
