An operator must obey a stop signal from who?

• A. Anyone
• B. The supervisor only
• C. The signal person only
• D. The operator

Answer: (A)

Stop signals are a safety control that can come from anyone who observes a hazard, and the operator must respond immediately by stopping. This ensures dangerous movements are halted right away, reducing the chance of injury while a safer plan is established. The authority to direct operations still rests with the signal person or site supervisor in normal workflow, but a stop signal from any worker takes effect instantly to protect people and equipment. After stopping, the operator should assess the situation and await further instructions from the designated person in charge before resuming.
