How often should pump tank extinguishers be internally examined?

Pump tank extinguishers should be internally examined annually to ensure their functionality and safety. This regular inspection is crucial because it allows for the identification of any potential issues, such as corrosion or leaks, that could compromise the extinguisher's effectiveness in an emergency. Given that these extinguishers are filled with water and may contain additives, their maintenance is essential to maintain the integrity of the internal components and the overall firefighting capabilities.

While other intervals for inspection may be established by various regulatory bodies for different types of extinguishers, the annual examination is standard practice for pump tank extinguishers to ensure they remain ready for use when needed. The importance of this annual check reinforces the commitment to safety and reliability in fire prevention and response efforts.
