How can you tell if a fire extinguisher is outdated?

To determine if a fire extinguisher is outdated, it's important to check the manufacturing date or the inspection tags. Most fire extinguishers have a label or tag that lists the date of manufacture. This date is essential because fire extinguishers have a shelf life, typically ranging from 5 to 15 years, depending on the type.

Additionally, inspection tags not only indicate the last inspection date but also provide important information on maintenance and when the next inspection should take place. This helps you ensure that the extinguisher is in compliance with safety regulations and ready for use. Regular maintenance and checks are critical, as an outdated or improperly maintained fire extinguisher may fail to operate effectively in an emergency.

While other options may provide some information, they do not offer the direct evidence that the physical attributes of the tag or label will provide regarding the extinguisher's freshness and readiness for use.
