A "Drain - Must Be Open at All Times, In Case of Fire Do Not Shut Valve Until Fire Is Entirely Out" sign is a safety sign used in buildings with fire sprinkler systems to provide specific instructions regarding the drainage valve associated with the sprinkler system.

The purpose of this sign is to ensure the proper functioning and effectiveness of the fire sprinkler system during a fire emergency. The drain valve is a critical component that allows the system to remove excess water or condensation and maintain its readiness for operation.

The instruction to keep the drain valve open at all times ensures that the fire sprinkler system can perform optimally, preventing potential issues such as clogs, reduced water flow, or impaired sprinkler operation due to stagnant water in the system.

The additional instruction not to shut the valve until the fire is entirely out is vital during a fire incident. Closing the drain valve prematurely could lead to a loss of water pressure in the system, resulting in decreased sprinkler effectiveness and potentially hindering firefighting efforts. Keeping the valve open until the fire is completely extinguished helps maintain continuous water supply to the sprinklers, aiding in controlling and suppressing the fire.

Drain - Must Be Open at All Times, In Case of Fire Do Not Shut Valve Until Fire Is Entirely Out signs are typically installed near the drain valve or in a location where they are easily visible to personnel responsible for building maintenance and fire safety.

Having such signs in place helps ensure the proper operation and functionality of the fire sprinkler system, contributing to efficient fire protection and effective emergency response capabilities in the building.
