If an alarm code is displayed during operation, where should you refer to for the proper procedure?

• A. The manual for the specific equipment.
• B. Your memory from training.
• C. A generic safety poster in the site trailer.
• D. Colleagues' informal guidance.

Answer: (C)

Alarm codes are device-specific, so you should refer to the manual for the exact equipment to interpret the code and follow the prescribed steps. The manual shows what the code means, the actions to take, any safety precautions, and whether a shutdown or lockout is required. Relying on memory from training can be risky here because different machines use different codes and procedures. A generic safety poster in the site trailer covers broad safety reminders but doesn’t provide the precise instructions needed to respond to a specific alarm. Colleagues’ informal guidance can be helpful for general concerns but may be outdated or incorrect for this alarm. If the manual doesn’t resolve the issue, follow the site’s escalation or shutdown procedures and inform supervision.
