What does a durable 2x3 weatherproof label indicate for fire extinguishers?

A durable 2x3 weatherproof label on fire extinguishers serves as an essential tool for communicating vital maintenance and testing information. This label typically details the inspection dates, maintenance records, and any relevant service history, ensuring that the extinguisher is up to code and functioning properly. Regular maintenance is critical in ensuring that the extinguisher will perform effectively in the event of a fire, making this label an important safety feature.

In comparison, other options do not accurately represent the primary purpose of the weatherproof label. For instance, while knowing the type of extinguisher is important, it is usually indicated on the extinguisher itself or in accompanying documentation rather than specifically on this label. The expiry date is generally not placed on the 2x3 label but instead marked directly on the extinguisher or its documentation, as is the manufacturer location, which is also not typically included in this context.
