Pipe and fittings shall be made of what material?

• A. Wood
• B. Non combustible materials
• C. Plastic
• D. Glass

Answer: (C)

Piping and fittings are chosen to work safely with the system’s fluid, temperature, and installation environment. Plastic piping (such as CPVC or PVC used in many wet chemical kitchen systems) is often selected because it resists the specific extinguishing agent involved, stands up well to corrosion, is lighter and easier to install, and is cost-effective for the typical small-diameter runs in kitchen hood piping. Wood and glass are unsuitable because they’re flammable or fragile and wouldn’t hold up under heat or impact. The idea of non combustible materials is a general safety requirement, but plastic is the practical, code-supported choice in many modern kitchen fire suppression piping applications due to its chemical compatibility and ease of installation.
