Kitchen Exhaust
Kitchen Exhaust Hood Cleaning and NFPA 96 Compliance
Grease in the hood is the easy part. Here's what NFPA 96 expects for the duct riser, the fan and the record you keep on file.
Hood cleaning is a system, not a surface
NFPA 96 covers the entire exhaust path: filters, hood plenum, the full duct riser, and the rooftop fan housing and blades. A crew that polishes the stainless and leaves the riser loaded has not brought the kitchen into compliance, and an inspector or insurance adjuster will find it.
Required frequencies
- Solid fuel cooking — monthly.
- High-volume operations such as 24-hour kitchens, charbroiling and wok cooking — quarterly.
- Moderate-volume sit-down restaurants — semi-annually.
- Low-volume operations such as churches, day camps and seasonal kitchens — annually.
The record that protects you
Every service should produce a dated certificate, before-and-after photos of the hood, riser and fan, and notes on any inaccessible sections. Keep it on-site; fire marshals ask for it, and carriers ask for it after a loss.
