During an alarm activation, what is the immediate action required by the operator?

• A. The operator needs to immediately inform the BDOC controller
• B. The operator must silence the alarm
• C. The operator must reset the system
• D. The operator must log the event with timestamp

Answer: (A)

The immediate action is to inform the BDOC controller. Notifying BDOC at once starts the formal incident response, allowing the supervisor to assess the situation, classify the alarm, and marshal the appropriate responders. Silencing or resetting the alarm before BDOC is notified can bypass procedures or obscure critical information, and while logging the event with a timestamp is important for records, it does not initiate the response process—the alert should come first so the incident is handled under proper oversight.
