What must be done if a control valve is found to be closed during an inspection?

In the event that a control valve is discovered to be closed during an inspection, it is essential to open the valve immediately and verify its proper operation. This practice is crucial because a closed control valve can prevent the sprinkler system from functioning correctly in the event of a fire, posing a significant risk to safety. By opening the valve and ensuring that it operates as intended, you maintain the integrity and readiness of the fire protection system, allowing it to provide the necessary coverage in an emergency situation.

Moreover, checking that the valve operates correctly helps to identify any issues that may require maintenance or adjustment. Regular inspection and testing of control valves are key components of a comprehensive fire safety plan, which ensures that fire suppression systems will perform effectively when needed. Prompt action in this scenario helps to prevent potential failures during a fire emergency.
