This Valve Controls Automatic Sprinkler System and must Always be Kept Open - Safety Signs by Caledonia Signs

Clearly indicate the purpose and operational requirement of a valve within a building’s sprinkler system. This type of valve regulates the water supply to the automatic sprinkler system, and keeping it open is essential to ensure the system can function effectively in the event of a fire. Closing the valve could render the sprinkler system inoperative, significantly increasing the risk of fire damage and endangering lives.

Using this sign helps ensure compliance with fire safety regulations and standards, such as BS EN 12845 (Automatic Sprinkler Systems – Design, Installation, and Maintenance). It serves as a constant visual reminder to building occupants, maintenance staff, and contractors that the valve must remain open at all times. This reduces the risk of accidental or unauthorised closure and supports routine inspection and maintenance practices to keep the fire protection system fully operational.

Placement of the sign is crucial for effectiveness. It should be installed directly above, adjacent to, or on the valve it refers to, at eye level, and in a location free from obstructions. In larger buildings or areas with multiple sprinkler valves, additional directional signage may be used to guide personnel to critical valves. Photoluminescent or reflective signs are recommended in areas with low lighting or where visibility may be reduced during emergencies.

Additionally, displaying this sign promotes a culture of fire safety and preparedness. It ensures that personnel understand the critical nature of the valve, reinforces proper operational procedures, and helps maintain the integrity of the automatic sprinkler system. Consistently visible signage supports compliance, reduces the risk of system failure, and demonstrates the organisation’s commitment to protecting lives and property.
