Grease Fire Prevention Tips for Nashville Restaurants

Published: February 12, 2026 | Nashville Hood Cleaning Pros

Grease fires are one of the leading causes of restaurant fires, causing millions of dollars in damage annually and putting lives at risk. The good news is that most grease fires are preventable with proper maintenance and attention to your kitchen exhaust system.

Understanding Grease Fire Risk

Commercial cooking produces grease-laden vapors that travel through your hood and into the ductwork. Over time, this grease accumulates, creating a highly flammable coating throughout your exhaust system. When temperatures get high enough—or if a flame reaches the ductwork—this accumulated grease can ignite.

Prevention Tip #1: Regular Professional Cleaning

The single most effective way to prevent grease fires is to maintain a regular professional hood cleaning schedule. NFPA 96 recommends cleaning frequencies based on cooking volume:

• Monthly: Solid fuel cooking, 24-hour operations
• Quarterly: High-volume frying, charbroiling
• Semi-annually: Moderate cooking volume
• Annually: Low-volume or seasonal operations

Prevention Tip #2: Daily Maintenance

Between professional cleanings, your kitchen staff should perform daily maintenance:

• Clean baffle filters daily (most are dishwasher-safe)
• Wipe down visible hood surfaces at closing
• Check for grease drips or unusual odors
• Inspect the hood for visible grease buildup

Prevention Tip #3: Maintain Fire Suppression Systems

Your automatic fire suppression system is your last line of defense. Ensure it's:

• Inspected semi-annually by a certified technician
• Not blocked by equipment or storage
• Equipped with properly charged extinguishers
• Tested according to manufacturer specifications

Warning Signs to Watch For

Train your staff to recognize these warning signs:

• Visible grease dripping from the hood
• Unusual odors coming from the exhaust
• Excessive smoke during normal cooking
• Rattling or unusual sounds from the fan
• Grease stains on the roof

What to Do If a Grease Fire Starts

Despite prevention efforts, fires can still occur. If a grease fire starts in your kitchen:

1. Activate the fire suppression system immediately
2. Evacuate staff and customers
3. Call 911
4. Never use water on a grease fire
5. Use a Class K fire extinguisher only if safe to do so
