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

Plant operators are considered safety-critical workers because they are responsible for the safe and efficient operation of machinery and equipment that can pose significant hazards to themselves, their coworkers, and the environment. Their decisions and actions directly impact operational safety, including managing risks associated with equipment malfunctions, chemical processes, and emergency situations. Consequently, their training and adherence to safety protocols are essential to prevent accidents and ensure compliance with regulatory standards.
