After an annual extinguisher maintenance, which item is typically updated?

• A. Service tag is updated.
• B. The batch number is changed.
• C. Gauge replaced.
• D. The location is changed.

Answer: (A)

Documentation of service is the focus here—the service tag is updated after annual maintenance. This tag stores the key details of the work: the date of service, the technician or company that performed it, and the next due date for inspection or recharge. Updating it creates a visible, reliable record that the extinguisher has been checked and is compliant, making future inspections quick and straightforward. The batch number is a fixed manufacturing identifier and doesn’t change with routine maintenance. The gauge is checked during service but isn’t normally replaced unless there’s a defect. The location isn’t part of the maintenance record and would only change if the extinguisher itself is moved.
