When should a red tag be used on a fire extinguisher?

A red tag is used on a fire extinguisher to signify that the extinguisher is impaired. This impairment might indicate that the unit is not functioning as intended, such as being damaged, needing maintenance, or having components that have failed. Identifying an extinguisher as impaired is critical for safety, as it alerts users that the extinguisher cannot be relied upon in an emergency situation.

By marking the extinguisher with a red tag, it becomes easily recognizable that immediate attention is needed, whether it calls for repairs or replacement. This system helps ensure that individuals in the vicinity are aware of the extinguisher's status and do not attempt to use it in a situation where it may fail.

In contrast, a fully operational extinguisher would not warrant a red tag, nor would an empty one, as the latter would typically be tagged differently to indicate it needs to be filled. A testing phase for an extinguisher is also not represented by a red tag, as that phase would require tagging that indicates it is out of service for inspection, not necessarily marking it as impaired.
