What should be included on an extinguisher maintenance tag?

• A. Owner's phone number.
• B. Inspection dates.
• C. Initials of the person performing maintenance.
• D. Any repairs or replacements.

Answer: (D)

Extinguisher maintenance tags are meant to document what was done to keep the unit ready for use. The most important item to include is any repairs or replacements, because that directly records actions that affect safety and the unit’s readiness. Knowing that a component was replaced or a repair completed helps inspectors understand the current condition and what further steps, such as recharging, may be needed. An owner's phone number isn't part of the service history. Including inspection dates and the technician's initials is common, but without noting repairs or replacements, the tag wouldn’t tell the full story of what actually happened to the extinguisher.
