What should be done if an operator feels unwell before operating the dumper?

If an operator feels unwell before operating the dumper, the most responsible action is to report to a supervisor and refrain from operating. This decision prioritizes the safety of the operator and others on site. Operating heavy machinery while unwell can impair judgment, reaction times, and overall performance, significantly increasing the risk of accidents or injuries. By notifying a supervisor, the operator ensures that the situation can be managed appropriately, which may include assigning another operator to take over or addressing any issues related to the operator's health. This approach aligns with workplace safety protocols that emphasize the importance of being in good health when operating machinery to maintain a safe working environment.
