As we discussed in our previous blog, commercial kitchen fires due to improperly cleaned hoods and exhaust systems are a significant risk to restaurants. Other than cleaning your hoods, you can also implement a simple commercial kitchen hood maintenance program and reduce your risks preventively.

Here are 10 Preventive Maintenance Tips for your Commercial Kitchen Hood:

  • Keep it clean. Have a maintenance schedule to keep your hoods and exhaust system cleaned. Check out our frequency guidelines on our FAQ page.
  • Keep fan belts adjusted and inspect it for cracks and wear.
  • Check electrical wiring. Give it a visual inspection, looking for loose wires or other obvious signs of trouble or shorting.
  • Keep the grease filter clean. This should be done weekly at a minimum. If you’re cooking with more grease, you’ll need to increase this to multiple times per week. Have this added to your maintenance plan schedule.
  • Check the fan blades to make sure they’re still balanced. When the blades get dirty, they can get out of balance, which can cause damage over time. Often, cleaning the blades will take care of the imbalance.
  • Along with the fan blades are the fan blade bearings. Keep those lubricated to ensure the fan motor has as little friction as possible.
  • In addition to the fan, keep the motor lubricated.
  • Check the seals on all covers to ensure that oils, fats, and grease are not getting through these.
  • Get up on the roof and check that fan exterior. It is exposed to sun, weather, and the Arizona monsoons!
  • Do a final double-check Go over the entire system and give it a last look.


Create a written program the preventive maintenance of your commercial kitchen hood and exhaust system. Each time you do an inspection, write down the results and note any corrective action taken. A simple checklist will go a long way to keeping your restaurant kitchen safe from fires caused by improperly maintained or cleaned kitchen hoods.

With most recent reports showing commercial kitchen fire damage costing businesses over $56-million, it is extremely important for you to keep your kitchen safe. A proper restaurant kitchen hood cleaning is the best fire prevention you can make to avoid disaster in your kitchen. Fires often occur from vent systems that are not properly cleaned.


We don’t want you to become a statistic. Far too many preventable kitchen fires are happening in commercial kitchens, many due to improperly cleaned equipment and neglected kitchen hoods.

Here are a few statistics on commercial kitchen fires:

  • Each year, there are approximately 1500 commercial kitchen fires in eating and drinking establishments alone, or four per day! (NFPA)
  • 22% of these fires were caused by improperly cleaned equipment (NFPA)
  • 61% of all kitchen fires were caused by cooking equipment (NFPA)
  • There was over $165M in damages from these fires over a five year period. There were also over 100 injuries and five fatalities. (NFPA)


While 61% of all commercial kitchen fires were caused by cooking equipment, there are other causes for kitchen fires that you need to be aware of, including:

  • Electrical systems, including wiring, breakers, and lighting
  • Heating equipment for climate control
  • Smoking materials
  • Arson, or intentional fires

Except for that last one, all of these are preventable through proper maintenance, inspections, and working within the local and national fire prevention codes.


There are steps you can take to prevent kitchen fires. Most importantly, you want to have a good cleaning schedule for your kitchen hoods and vents with a company that cleans to NFPA96 standards and according fire safety regulations for commercial kitchens (learn more in our FAQs). Hoods that aren’t cleaned properly and regularly build up fire fuel that is just waiting to ignite. Don’t let that happen in your kitchen.
Here are some other things you can do to prevent kitchen fires:

  • Install a fire suppression system. These will minimize damage and even safe lives — and your business — should a fire break out despite your preventative actions.
  • Clean the entire exhaust system. Many cleaning companies will clean only the parts of the ventilation system that are visible, which is a very dangerous practice. On-Site Commercial services cleans the entire system.
  • Keep fire extinguishers charged and easily available. You need both Class K (grease, fat, and oil fires) available near cooking equipment and Class ABC for other areas of your business.
  • Train your team on fire prevention and fire reaction. Have written standards and do regular training on preventing kitchen fires and how to react to and stay safe in the event of a fire.


Commercial kitchen fire safety may be required by law, but many restaurant owners fail to comply with regulations. On-Site Commercial services makes it easy to stay in compliance and stay safe by scheduling regular cleanings of your commercial kitchen hood and ventilation system. By doing regular, thorough cleanings, you’ll keep your business from becoming one of those scary statistics.

Regular Cleaning Prevents Grease Buildup in Commercial Kitchen Ventilation

There are many local and state laws and regulations pertaining to the cleaning frequency that is required for commercial kitchen hoods in Arizona restaurants and food service facilities.  It’s important to bring in a company that knows what needs to occur, and how often the ventilation equipment needs to be cleaned. Involving experts in the process  can help increase the overall life and efficiency of the restaurant’s ventilation equipment significantly.

Kitchen Ventilation Fan


Keeping the kitchen hoods, exhaust fans, grease filters and duct work clean and sanitary is required by most local health codes.  In accordance with those codes you should adopt a regular cleaning schedule for kitchen hood equipment.  On-Site Commercial Services suggests that no system should ever go longer than six months without a cleaning, and often, more frequent cleaning is necessary. These environments include any kitchen with grease producing appliances like charcoal broilers, deep fryers or grills.  Generally, these kitchens will have a significant amount of built up grease, due to the vegetable oils often used during the cooking process.

Looks clean to me!

The overall amount of food being prepared or cooked will usually determine the frequency that the cleaning should occur.  Obviously, higher volume kitchens will need hood cleaning more frequently, but even kitchens with a lighter amount of usage should never be ignored.

The grease that can build up can be dangerous and can jeopardize the safety of your employees, patrons, and YOU!

Also, besides grease,  bacteria can build up in a commercial kitchen environment and unhealthy standards can exist for employees and patrons.  Respiratory illnesses or gastrointestinal issues are often common, and whenever there is a high incidence of illness that is traced back to the same restaurant, a health department inspection is usually conducted.  Any indication that the problems are related to improper cleaning of the commercial kitchen ventilation system will lead to temporary closure of the establishment until the problem is remedied. The restaurant owner faces possible fines and health or fire code violations. Don’t get your business on the local Phoenix news  because of a grease fire, or an outbreak of some bacterial  strain. Get your kitchen ventilation hoods cleaned regularly and properly. Your business could depend on it !!
