A Class C operator must be on-site at a staffed facility during all hours of operation.

• A. True
• B. False
• C. Only during emergencies
• D. Only at night

Answer: (A)

Having a Class C operator on-site during all staffed hours keeps operations continuously supervised by a qualified person who can monitor instruments, respond to alarms, and carry out safe start-up and shutdown procedures. This presence supports immediate handling of abnormal conditions and ensures compliance with safety and regulations. The idea behind the requirement is that supervision isn’t just for emergencies or nighttime; during any time the facility is staffed, an operator must be available on-site to oversee day-to-day operation and intervene as needed.
