Vent Hood Cleaning Tips for Restaurant Fire Safety

Vent hood cleaning should never be an afterthought for restaurant owners. It’s one of the most critical components of a commercial kitchen’s fire safety and hygiene strategy. Yet, it’s often overlooked—until there’s a problem. This guide breaks down the essentials, so you know when, why, and how to stay compliant and safe.

Vent Hood Cleaning

Why Vent Hood Cleaning Matters

Vent hoods are designed to trap grease, smoke, and other airborne particles that can accumulate quickly in high-volume kitchens. Over time, this buildup becomes a significant fire hazard. According to the National Fire Protection Association (NFPA), kitchen exhaust systems are a leading cause of restaurant fires. Regular vent hood cleaning isn't just recommended—it’s required by law under NFPA 96 standards.

Insurers will also investigate the cleanliness of your exhaust systems in the event of a fire. Lack of documentation or visible neglect can jeopardize your claim and your coverage.

Cleaning Frequency Guidelines

Different types of establishments require different cleaning schedules:

  • Non-Grease Appliance Hoods: Clean annually (e.g., churches or seasonal facilities).

  • Pizza Ovens and Similar Appliances: Every 180 days.

  • High-Volume Kitchens (Hotels, Cafeterias): Every 90 days.

  • Fast Food, 24-Hour Restaurants, and Wood-Burning Stoves: Every 30 days due to heavy grease output and fire risk.

How to Clean a Vent Hood

Per NFPA 96, only certified professionals should clean commercial vent hoods. A reputable company will:

  • Fully disassemble the hood and remove filters.

  • Degrease all surfaces, troughs, and grease cups.

  • Inspect and clean the fan and belts.

  • Provide documentation—and ideally, photos—for every job.

Avoid underqualified or budget cleaning services that lack proper tools and certifications. This is not an area where you should cut corners.

The Bottom Line

Proper vent hood cleaning keeps your kitchen safe, your insurance intact, and your business compliant. It also protects your employees and customers. Don’t let neglect be the reason your restaurant becomes a statistic.
