Which class of operator is responsible for the day-to-day operation, maintenance, and recordkeeping at each facility?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (B)

Operator roles are arranged by how actively they manage the plant. The class responsible for day-to-day operation, maintenance, and keeping records is the on-site operator. This role is trained to monitor and control processes, respond to changing conditions, perform routine inspections and preventative maintenance, and maintain logs, work orders, and regulatory records. Having the operator who is present on the floor ensures timely adjustments, proper documentation, and quick response to issues, which is essential for safe, compliant, and efficient facility operation. Other roles focus on higher-level oversight, policy, audits, or specialized tasks, rather than the continuous, hands-on duties of running the plant day to day, so they aren’t the best fit for these ongoing responsibilities.
