Which statement best describes the nozzle requirement for wet chemical systems?

• A. It must be permanently marked
• B. It must be brass, stainless steel, or other corrosion resistant material
• C. It must be permanently marked and brass, stainless steel, or other corrosion resistant material
• D. It requires no marking

Answer: (C)

Nozzles in wet chemical systems must be permanently marked and made from corrosion‑resistant material. The permanent marking provides traceability and ensures the nozzle is the approved type for that system, which helps inspectors and maintenance staff verify correct components and keep service records. The corrosion‑resistant material, such as brass or stainless steel, stands up to the harsh kitchen environment—grease, moisture, heat, and cleaners—so the nozzle maintains its spray pattern and reliability over time. Relying on just marking or just material could lead to misidentification or premature failure, so requiring both guarantees proper identification and durability, which is why this combined requirement is the best description.
