Common Commercial Kitchen Inspection Problems and How to Avoid Them

For restaurant owners and kitchen managers, an inspection can be stressful when you aren’t sure what an inspector may find.

While food temperatures, sanitation, storage and equipment are all important parts of food safety inspections, your commercial kitchen’s exhaust system should not be overlooked.

Your kitchen hood is only one part of the system. Grease-laden vapors travel through the hood, filters, ductwork and eventually to the rooftop exhaust fan. When these areas aren’t properly maintained, grease buildup can become a costly problem.

At Centex Pressure Washing, we help restaurants throughout Central Texas keep their commercial kitchen exhaust systems clean and maintained.

1. Grease Buildup in the Exhaust System

One of the biggest problems restaurant owners overlook is grease buildup beyond the visible hood.

Grease can accumulate inside:

Commercial kitchen hoods

Grease filters

Exhaust ducts

Rooftop exhaust fans

Fan housings and surrounding components

NFPA 96 addresses inspection of commercial cooking exhaust systems for grease buildup, with inspection frequency based on the type and volume of cooking.

The problem is simple: what you can’t see can still affect your exhaust system.

A kitchen may look clean from the cook line while significant grease buildup is hidden farther up the exhaust system.

2. A Dirty Rooftop Exhaust Fan

The rooftop exhaust fan is easy to forget because restaurant employees and customers rarely see it. But the fan plays an important role in moving cooking smoke and grease-laden vapors out of the kitchen. Grease buildup on the fan and housing should be addressed as part of maintaining the overall exhaust system.

When a cleaning company only focuses on what is visible from inside the kitchen, the rooftop portion of the system can be overlooked.

That’s why a proper commercial kitchen exhaust cleaning should address the entire system, not just the hood.

3. Dirty or Grease-Laden Exhaust Ductwork

The ductwork connects your kitchen hood to the rooftop exhaust fan, making it another critical part of the system.

Because ducts are enclosed, restaurant staff generally can’t tell how much buildup is inside without proper inspection.

NFPA materials identify the hood, duct and fan as components of the commercial cooking exhaust system that require attention for inspection, maintenance and cleanliness.

Regular professional cleaning helps remove accumulated grease and keeps the exhaust system maintained.

4. Poor Airflow

If your kitchen exhaust system isn’t moving air properly, you may notice excessive smoke, heat or cooking odors lingering around the kitchen.

Airflow problems can have multiple causes, so cleaning isn’t always the only solution. However, grease buildup and maintenance issues can contribute to an exhaust system not operating as intended.

Keeping the hood, ducts, filters and exhaust fan properly maintained is an important part of overall kitchen exhaust maintenance.

5. Waiting Until Inspection Day

One of the most common mistakes restaurant owners can make is treating exhaust cleaning as something to think about only when an inspection is coming up.

Inspection readiness should be part of your regular maintenance routine.

Cleaning schedules can vary based on the type and volume of cooking, and requirements can also depend on the authority having jurisdiction. NFPA 96 materials identify different inspection intervals for solid-fuel, high-volume, moderate-volume and low-volume cooking operations.

Don’t wait until an inspector points out a problem. Build commercial kitchen exhaust cleaning into your regular maintenance schedule instead.

What Can Restaurant Owners Do? Before your next inspection, take a look beyond the cooking line. Ask:

✔ When was our last hood cleaning?

✔ Has the exhaust ductwork been professionally cleaned?

✔ Has the rooftop exhaust fan been cleaned?

✔ Is grease buildup visible anywhere in the exhaust system?

✔ Do we have documentation of our previous cleaning and maintenance?

✔ Are we keeping up with the maintenance schedule appropriate for our type of cooking operation?

If you don’t know the answers, that’s a good reason to have your system evaluated.
