Why are plant operators called safety critical workers?

Plant operators are considered safety critical workers because they play a crucial role in managing and overseeing operations that can pose significant risks to health, safety, and the environment. Their responsibilities include monitoring equipment, ensuring compliance with safety protocols, and responding to emergencies. A lapse in their judgment or performance can lead to severe accidents, including injuries or environmental disasters. As a result, their training and adherence to safety standards are vital for maintaining safe operational conditions.
