Why is it important not to leave a fire extinguisher without a tag or label?

A fire extinguisher must have a tag or label to ensure it meets local and national fire codes and regulations. These tags serve several purposes, such as indicating that the extinguisher has been inspected, maintained, and is ready for use. A missing tag or label may lead to a code violation, which can result in fines or other penalties for the owner. Moreover, it can affect the safety of individuals in the building by creating uncertainty about the extinguisher's functionality.

While other options touch on important aspects of fire safety, they do not capture the immediate regulatory and safety implications associated with a missing tag or label. Maintaining compliance with codes is crucial for fire safety, ensuring that all equipment is properly maintained and available when needed.
