Red tags must include which of the following information?

The correct answer pertains to the critical role that red tags play in fire safety management. Red tags are used to identify any impairments or deficiencies associated with a fire extinguisher. This information is vital because it alerts users and responsible personnel that the extinguisher is not in a fully operational condition, indicating necessary repairs or maintenance needed.

Knowing the details of impairments helps to ensure that everyone is aware of the extinguisher’s status, which is especially crucial in an emergency situation where the performance of fire extinguishers can be life-saving. Therefore, including certification details on the red tag serves to confirm that the extinguisher has been inspected and is compliant with safety regulations, further reinforcing its reliability when needed.

The other choices, while relevant to broader fire safety practices, do not specifically address the purpose of the red tags in relation to impairments and operational status. It's essential for red tags to focus on impairments to maintain a clear and effective safety protocol.
