Why is it important for signage to indicate flow direction at standpipe outlets?

Indicating the flow direction at standpipe outlets is crucial because it directly assists firefighters in understanding the system's operation during an emergency response. Clear signage allows firefighters to quickly determine the correct orientation for connecting hoses, thereby facilitating a more efficient and effective approach to extinguishing fires. In high-stress situations, every second counts, and having a visible indication of how to access the water flow can save valuable time and potentially prevent loss of life and property.

While compliance with local building codes is important, the primary purpose of these signs is not for decoration or aesthetic reasons but to provide essential information that enhances the safety and effectiveness of firefighting efforts.
