The cleaner your kitchen exhaust duct system, the more effectively you can prevent build-up of grease and debris that can lead to fires. And, how often and how well a system is cleaned is highly dependent on access. By installing a duct access door, you make it easier for professional cleaners to get inside the system for thorough cleaning.

Additionally, proper access to the exhaust duct system is required under NFPA fire codes. NFPA #96 section 1-3.1.3 says: “All interior surfaces of the exhaust system shall be reasonably accessible for cleaning and inspection purposes.”

The National Fire Protection Association (NFPA) is the authority on fire, electrical and building safety. The association has established Fire Code #96 with various expectations that restaurants are required to comply with.

Main causes of restaurant fires and the codes that relate to them

Cooking causes 59 percent of restaurant fires. Nearly all of these types of fires are small and contained, resulting in limited damage. Cooking fires may be caused by failure to keep up with exhaust system inspection and cleaning. Hood filters and spark arrestor filters above stoves, deep fat fryers or open fired grills can be fire hazards if not cleaned regularly. Fans and ducts can also collect grease over time. The codes relating to these problems include:

Stains around a grease dumpster aren’t just unsightly; it can put you in violation of EPA clean water laws and local environmental regulations. Under managed dumpster grease can degrade pavement, attract rodents and cause unpleasant stains and odors. It can also cause an unsafe walking surface, exposing you to slip and fall liabilities. Read on to learn how to manage grease around your restaurant’s dumpsters and keep yourself in compliance with local law:

Easily Remove Grease

Grease stains can be stubborn and difficult to remove. The usual grease dumpster cleaning method of washing grease down into sewers can put you in violation of EPA regulations. It is also considered a pollutant and disposing of it improperly can result in costly fines.

Your hood filters are the first line of defense in your kitchen exhaust system. They keep grease and debris from entering the ventilation system to maintain environmental quality and reduce the risk of fires. But, to do their job well, your exhaust hood filters must be in top working condition.

There is no set schedule for replacing hood filters. The life of a filter will depend on factors that include the type of filter, how well it’s maintained, and the amount of grease, debris and heat it is exposed to. Many busy restaurants need to replace exhaust hood filters every six to eight months. Others are able to go as long as two years between replacements. Different filters have different effective lives. Stainless steel filters last longer than aluminum or galvanized. You will also get longer life from heavy-duty filters vs. standard-duty.

Choosing the right hood grease filter is an essential part of a safe, comfortable and productive commercial kitchen. How do you narrow down the search? The key is to answer two simple questions about your kitchen and cooking techniques:

Does your cooking equipment burn solid fuel?

Mesquite, briquettes, charcoal and hardwood are all examples of solid fuel. If the answer to this question is “yes,” then you need a spark arrestor filter. A spark arrestor is a steel screen mounted to a baffle filter. Its function is to stop flames, embers and sparks from finding their way into the hood exhaust ductwork.

If the answer is “no,” move on to the next question to help you choose the right baffle hood grease filter.

Baffle Boss

There’s no doubt you need to remove baffle filters regularly for cleaning purposes. How do you perform this task safely? Do you rely on knocking the filters out of place, or even climbing onto the cooking equipment to retrieve them? These unsafe methods could damage the hood filter or even result in employee injury.

The safest bet is to abandon these rudimentary methods and invest in a useful hood filter remover and lifting tool called the Baffle Boss. This device makes removing filters easy, safe and hassle-free, even for the shortest kitchen staff member.

If you think the type of commercial kitchen lighting you use makes no difference, think again. LED kitchen lights are far more advanced than incandescent and fluorescent bulbs. When you choose an LED kitchen light, you can expect to enjoy plenty of benefits, but remember, not all LEDs are created equal.

Benefits of LED Lighting

  • Energy savings: LED lamps consume at least 75% less energy than incandescent bulbs, reducing operating expenses. Just ask restaurants that have already implemented LED kitchen lighting, such as Chili’s, which enjoys an estimated yearly savings of $3.7 million across all its franchise locations. Applebee’s also reports an 80% reduction in its kilowatt hour light load. Continue reading

Some of the most common complaints about hood filters are related to rattling, cleaning, and repair issues found with riveted style filters. Riveted construction is very common and certainly doesn’t prevent a filter from doing its job. They are a little cheaper and UL Listed models can meet all NFPA fire code standards. However, all things being equal, a welded product is always a superior option to riveted from the standpoint of durability and maintenance.

Commercial kitchen exhaust hood and ventilation systems are essential to providing a clean environment by removing grease-laden air and pollutants. But without properly fitting hood filters, the system can quickly become unbalanced, inefficient, and non compliant with building and fire regulations.

While hood filters are affordable and available in a range of sizes, many kitchen hoods don’t match up exactly with standard commercial hood filter sizes. Custom-sized filters are an option, but they can be very expensive. Luckily, you do not need to spend the extra money on custom-made filters. By using hood filter spacers, you can bridge the gap between your hood size and the filters available.
