Why are plant operators generally regarded as 'safety-critical' workers?

Plant operators are categorized as 'safety-critical' workers primarily due to the nature of their duties, which directly impact health and safety. Their role involves operating heavy machinery and equipment, often in environments where the potential for accidents and injuries is high. The decisions and actions taken by these operators can lead to serious consequences, not just for themselves but also for their colleagues and the general public.

For instance, if an operator misjudges the operation of a forward tipping dumper or fails to adhere to safety protocols, the results could be catastrophic, involving injuries or fatalities. This emphasizes the critical nature of their function in maintaining a safe working environment. Thus, their training and competencies are designed to ensure they can operate machinery safely and effectively, further corroborating their designation as essential personnel in operational safety.
