What is the minimum height for letters on a sign marking a remote fire department connection?

The minimum height for letters on a sign marking a remote fire department connection is established to ensure that the sign is legible from a reasonable distance, especially in emergency situations. A height of 1 inch for the letters strikes a balance between visibility and practicality, making it easy for firefighters and emergency responders to quickly identify the connection point during a fire event. This standard takes into account typical viewing angles and distances that responders may encounter when approaching a building during an emergency.

Choosing a height less than 1 inch would compromise readability, particularly under stressful conditions or when visibility is impaired due to smoke or darkness. Signs that are too small can lead to delays in accessing these critical connections, highlighting the importance of adherence to this minimum height guideline in the NFPA 24 standard.
