Fire extinguishers that are impaired must use what tagging system?

The red tagging system is used to indicate that fire extinguishers are impaired or out of service. This tagging system is vital for safety, as it alerts personnel that the extinguisher may not function properly in case of a fire emergency. The visibility of the red tag ensures that everyone who encounters the extinguisher is aware of its status and can take appropriate action, such as not relying on it for fire suppression.

The other tagging systems, which include green, yellow, and blue, are designated for different statuses. Green typically indicates that an extinguisher is fully operational, yellow often relates to extinguishers that require servicing or maintenance, and blue is less standard but might represent specific cases or types of equipment depending on the context. Thus, the use of the red tagging system for impaired extinguishers is crucial for maintaining safety protocols and ensuring that fire protection measures are reliable.
