What type of sign is required at the system control riser supplying an antifreeze loop, dry system, preaction, or auxiliary system control valve?

• A. A Warning Sign
• B. An Information Sign
• C. A Confidential Sign
• D. A Notice Sign

Answer: (B)

The key idea is labeling what system a valve controls at the system control riser. For antifreeze loops, dry pipe, preaction, or auxiliary system control valves, an Information Sign is used because it provides general information about the equipment and its purpose, helping operators quickly identify which system is being controlled. It isn’t signaling a hazard (that would be a Warning), nor is it giving procedural instructions (a Notice), and there’s no need for a Confidential label. So the sign should be an Information Sign.
