What is a common cause of accidents involving heavy machinery?

Operator error due to a lack of training or attention is a common cause of accidents involving heavy machinery because skilled operation is critical for maintaining safety while using such equipment. Operators must be well-trained not only in the mechanics of the machinery but also in safety protocols, hazard recognition, and emergency procedures. A lack of experience or attention can lead to misjudgments or failure to notice potential hazards, increasing the risk of accidents.

While mechanical failure, environmental hazards, and excessive speed are factors that contribute to accidents, operator error often plays a more significant role because it encompasses the human element of machinery operation. Proper training can effectively reduce the likelihood of accidents caused by human mistakes, making it a primary focus in safety measures within the operating engineer field.
