How should you handle a malfunctioning interlock indicator?

• A. Operate the ride normally but monitor closely.
• B. Continue to operate but log the event.
• C. Do not operate the ride; tag out; notify maintenance; document the issue and wait for authorized clearance.
• D. Override the interlock to test.

Answer: (C)

Whenever a safety interlock indicator fails, treat it as a potential safety fault. The interlock is there to prevent the ride from operating under unsafe conditions, and if the indicator isn’t functioning, you can’t rely on it to confirm safe start-up or operation. The proper action is to stop using the ride, tag out the equipment so others can’t operate it, notify maintenance so a qualified technician can diagnose and repair the fault, and document the issue while awaiting authorized clearance to resume service. This sequence ensures the fault is inspected, repaired, and verified by someone with authority before the ride is back in service, protecting riders and meeting safety and regulatory requirements.

Other approaches are risky because they either ignore the safety risk or bypass safeguards. Operating while merely monitoring still leaves the ride in a potentially unsafe state, logging the event without taking corrective action doesn’t fix the problem, and overriding the interlock to test bypasses a critical safety feature and could lead to harm.
