Sprinkler Stop Valve - Safety Signs by Caledonia Signs

An essential fire safety tool used to clearly identify the location of the stop valve for a building’s sprinkler system. The stop valve allows firefighters, maintenance personnel, or trained staff to shut off the water supply to the sprinkler system in case of maintenance, system testing, or accidental discharge. Clear identification of the valve is crucial to ensure quick access during emergencies or routine operations, preventing water damage and ensuring the sprinkler system functions correctly when needed.

Using this sign helps ensure compliance with fire safety regulations and standards, such as BS EN 12845 (Automatic Sprinkler Systems – Design, Installation, and Maintenance). Proper signage reduces confusion during emergencies, supports maintenance procedures, and ensures that only trained personnel operate the valve. It also contributes to building safety by preventing unauthorised tampering, accidental shut-offs, or misuse that could compromise the fire protection system.

Placement of the sign is critical for effectiveness. It should be installed directly above or adjacent to the sprinkler stop valve, at eye level, and in a clearly visible location free from obstructions such as furniture, equipment, or stored items. In larger or complex buildings, directional signs may be used to guide personnel from main access points to the valve. Photoluminescent or reflective signs are recommended in areas where lighting may be low or in case of power failure.

Additionally, displaying a Sprinkler Stop Valve sign promotes a culture of fire safety and preparedness. It ensures that personnel can quickly locate and operate the valve when required, supports compliance with maintenance protocols, and reinforces the organisation’s commitment to protecting lives and property through proper fire protection system management.
