If an interlock indicator malfunctions, what is the correct action?

• A. Operate the ride with a note in the log.
• B. Tag out and notify maintenance; do not operate until cleared.
• C. Continue operation and report after shift.
• D. Override the interlock to test.

Answer: (B)

Interlock safety systems prevent the ride from starting unless all safety conditions are met. When the interlock indicator malfunctions, you can’t rely on that signal to confirm the safeguards are in place, so the proper action is to tag out the equipment and notify maintenance; do not operate until the issue is cleared. Tagging out means placing a clear, visible tag on the control or equipment (and applying lockout if required) to ensure the ride cannot be started. Maintenance will diagnose and repair the fault and verify the interlock function before the ride is returned to service. This approach prevents accidental startup or engagement of unsafe conditions that could injure riders or staff. Bypassing or delaying action, or attempting to operate with an unresolved interlock fault, compromises safety and could lead to serious harm. Once fixed, follow the proper procedures to reinstate service and document the repair.
