NFPA 96: Requirements for Commercial Cooking Operations

What is NFPA 96?

NFPA 96 is the ventilation and fire protection standards set by the National Fire Protection Association for restaurants and cooking operations.

Under NFPA 96, you will find there are several parts, including the fire code regulations for:

  • Hood inspections and cleaning frequency

  • Hood grease filters

  • Rooftop grease containment

Hood Grease Filter Requirements

Hood grease filters must be UL listed as they are fire code approved.

If your filter isn’t UL listed and a fire occurs at your business or restaurant, insurance may not cover any damages.

According to NFPA 96:


Grease Removal Devices


Listed grease filters, listed baffles, or other listed grease removal devices for use with commercial cooking equipment shall be provided


Listed grease filters and grease removal devices that are removable but not an integral component of a specific listed exhaust hood shall be listed in accordance with UL 1046


Mesh filters shall not be used unless evaluated as an integral part of a listed exhaust hood or listed in conjunction with a primary filter in accordance with UL 1046

Grease filters shall be listed and constructed of steel or listed equivalent material.

Grease filters shall be of rigid construction that will not distort or crush under normal operation, handling, and cleaning conditions

Grease filters shall be arranged so that all exhaust air passes through the grease filters.

Grease filters shall be easily accessible and removable for cleaning.

Grease filters shall be installed at an angle not less than 45 degrees from the horizontal

Rooftop Grease Containment Requirements

All restaurant rooftops are requires to have grease containment systems. Grease containment systems help prevent fires and major damages to your roof that could cost hundreds of thousands of dollars.

The NFPA states:


Rooftop Terminations

(4) The ability to drain grease out of any traps or low points formed in the fan or duct near the termination of the system into a collection container that is noncombustible, closed, rainproof, and structurally sound for the service to which it is applied and that will not sustain combustion

(6) Listed grease collection systems that meet the requirements of and


Exhaust Fans for Commercial Cooking Equipment

What Can Happen if I’m Not Up to Code?

A lot of not-so-good things can happen.

For one, you will risk fines and even temporary closure of your business.

An unclean hood can also result in fires. If you’re unable to prove to your insurance company that you’ve been keeping up with your regular hood cleanings by a professional hood cleaning company, they may not cover damages, that may result in losing your business entirely.
