What is the purpose of seals and tamper indicators on fire extinguishers?

The purpose of seals and tamper indicators on fire extinguishers is to confirm tampering or use. These seals are designed to show whether a fire extinguisher has been accessed or used since the last inspection or service. If a seal is broken, it provides a clear visual cue that the extinguisher may no longer be in proper working condition and should be inspected or serviced before being relied upon in an emergency situation. This feature is essential for ensuring that fire extinguishers are ready for immediate use when needed, as it helps safeguard against unauthorized handling and reinforces the importance of maintaining equipment integrity for safety.

Other options may seem relevant, such as indicating pressure or ensuring maintenance, but these functions are not specifically served by seals and tamper indicators. The primary role of these features is to indicate whether the extinguisher has been tampered with, serving as a crucial aspect of fire safety protocols.
