This component ensures that the extinguisher has not been accidentally or purposely discharged and verifies that it is ready for use in case of an emergency.

Regularly checking the tamper seal is a straightforward yet essential part of fire extinguisher maintenance. It helps to ensure that the extinguisher remains in a ready state. If the tamper seal is broken or missing, it is an indication that the extinguisher may have been used or tampered with, necessitating further inspection or maintenance. Consequently, this annual check plays a significant role in fire safety protocols, keeping the extinguisher operational and reliable.

Other maintenance tasks, such as pressure testing or an interior cleaning, typically follow different schedules and may not be required annually. Some might be needed every few years depending on the type of extinguisher or manufacturer recommendations, while testing the conductivity of a hose assembly is more specific to certain types of extinguishers, such as CO2 units, not as a standard annual requirement. Thus, the tamper seal check is a definitive action that should happen every year to ensure
