The materials for a wet chemical discharge nozzle should include which combination?

• A. Permanently marked
• B. Brass, stainless steel, or other corrosion resistant material
• C. Permanently marked and brass, stainless steel, or other corrosion resistant material
• D. Aluminum

Answer: (C)

Wet chemical discharge nozzles must be made from materials that resist the corrosive wet chemical agent and the kitchen environment, such as brass, stainless steel, or other corrosion‑resistant metals. They also need to be permanently marked so their identity, model, rating, and maintenance history are clearly traceable during inspections and servicing. This combination ensures the nozzle won’t degrade in use and can be reliably identified for proper upkeep, which is essential for system effectiveness and compliance. Why the other possibilities don’t fit: marking alone doesn’t protect against corrosion, and corrosion resistance without permanent marking leaves traceability and maintenance records uncertain. Aluminum is generally not preferred due to potential compatibility and durability concerns with the wet chemical agent.
