A post indicator valve for a private fire service main must be located at least how far from a building?

• A. 20 ft from the building
• B. 30 ft from the building
• C. 40 ft from the building
• D. 50 ft from the building

Answer: (C)

A post indicator valve on a private fire service main is placed to allow a clear shutoff and to show at a glance whether the valve is open or closed. The distance from any building is regulated to protect the valve from heat and flame exposure and to give firefighters and maintenance crews safe, unobstructed access. The required minimum distance is 40 feet from the building. Placing it closer (20 or 30 feet) would bring the valve into a higher risk area near structures, complicating emergency shutoffs and increasing potential heat or fire impact on the valve. Setting it farther away, such as 50 feet, would still meet the safety goals, but the question asks for the minimum distance, which is 40 feet.
