Which term refers to substances that prevent corrosion in piping?

• A. Light Hazard Occupancies
• B. Gauge Pressure
• C. Corrosion Inhibitors
• D. ASTM A 234

Answer: (C)

Corrosion inhibitors are substances added to the system water to prevent corrosion of metal piping and sprinkler components. They work by forming protective films on metal surfaces and by adjusting the water chemistry to make corrosion less likely, helping extend the life of residential sprinkler piping in NFPA 13R systems. The other terms aren’t about chemical protection: one is a fire- protection occupancy category, another is a pressure measurement, and the last is a piping fittings standard—none describe substances that prevent corrosion.
