Additionally, it includes checking the condition of hoses and nozzle, as well as ensuring that the extinguisher is easily accessible and visible.

Regular inspections are crucial because they help identify any potential issues that could compromise the extinguisher's effectiveness, ensuring it functions properly when needed. This practice is aligned with the guidelines set forth by the National Fire Protection Association (NFPA) and local regulatory standards.

For example, hydrostatic testing is a more specialized procedure required every five to twelve years, depending on the type of extinguisher, and is not performed annually.
