The hood plenum and blower must be cleaned at least once every how many months?

• A. 2 months
• B. 3 months
• C. 6 months
• D. 1 month

Answer: (B)

Regular kitchen vent systems collect grease in the hood plenum and blower, and this grease is highly flammable and can block exhaust airflow if it builds up. Cleaning these parts on a set schedule helps keep the fire risk low and the blower working efficiently. A quarterly interval—every three months—is a safe, practical baseline that reduces grease accumulation without being overly burdensome for most operations. If a kitchen handles especially oil-heavy cooking, the schedule might be adjusted to be more frequent, but three months is the standard minimum to maintain safety and performance.
