What does the tamper seal on an extinguisher indicate?

• A. It shows the extinguisher has not been tampered with
• B. It shows the unit has recently been serviced
• C. It shows the extinguisher has not been tampered with and is ready for use; break seal only when using
• D. It indicates the extinguisher is expired

Answer: (C)

The tamper seal is a safety indicator on the extinguisher’s pin thatshowsthe unit hasn’t been opened since the last service. It’s meant to deter tampering and to signal that the extinguisher hasn’t been discharged. You should break the seal only when you actually plan to use the extinguisher. If the seal is intact and other indicators—like the pressure gauge reading and the current service tag—are good, the unit is considered ready for use. The seal by itself doesn’t prove recent service or indicate expiry; those are shown on the service tag and by date markings.
