If buildup of grease or other material is present on water mist nozzle used to protect commercial type cooking equipment and ventilation system these nozzles must be replaced ___________.

• A. Monthly
• B. Annually
• C. Biannually
• D. Quarterly

Answer: (B)

Buildup on water mist nozzles can alter spray patterns, droplet size, and flow, which reduces coverage and the effectiveness of fire suppression. When grease or other material accumulates, cleaning might not reliably restore the nozzle to its rated performance, so replacement is the safer, more reliable option. Manufacturers and maintenance practices commonly call for replacing these nozzles on an annual basis to ensure they operate as designed between inspection cycles. In busy commercial kitchens, this annual interval balances reliability with practical downtime, reducing the risk of degraded protection.
