For the emergency stop, which statement best reflects the manual reset requirement?

• A. Manual reset is required
• B. Automatic reset is required
• C. No reset required
• D. Emergency stop is not required

Answer: (A)

Emergency stops are designed to latch and require a manual reset before the system can be restarted. When activated, the stop disables the equipment and stays in the stopped state until an intentional reset action is performed by the operator, ensuring hazards have been checked and conditions are safe before resuming. Automatic reset would allow the system to start again without deliberate confirmation, which is unsafe in flame effects operations. Therefore, manual reset is required.
