Signs Your Vent Hood Fans Need Cleaning

Signs Your Vent Hood Fans Need Cleaning and/or Replacement

Source

Denver, CO – Most restaurant owners understand the importance of engaging in a regular commercial kitchen cleaning schedule. Keeping cooktops and food preparation areas spotless is crucial for hygiene reasons, but it’s equally as important to ensure that kitchen hood fans and filters remain just as clean. Here’s why.

Grease and dust can build up in range hood fans and filters quickly, posing a potential fire hazard. Grease is highly combustible, so the risk of it catching alight and sparking a kitchen fire are increased if the residue build-up isn’t removed regularly.

The kitchen’s hood and ventilation system provide a layer of protection in eliminating air contaminants and odors caused by cooking. So it’s essential the filters and fans are not just cleaned and maintained regularly so they operate effectively; they also need to be cleaned properly, ideally by a professional hood services company, to minimize health and safety risks.

However, even with regular maintenance, there are times when a hood fan or filter will need to be replaced completely. Some signs to look for that could indicate a hood fan or filter may need to be replaced include:
  • You notice damage on the filter during a routine cleaning
  • The vent fan no longer draws smoke or cooking smells out of the kitchen as effectively
  • The exhaust fan makes unusual sounds or stops turning completely
The risk of an exhaust fan failing during operating hours could be devastating to any commercial kitchen operation. The risk of fire is dramatically increased, but there is also the problem of filling the kitchen and dining area with smoke.

The specialists at APS-Hoods recommend creating a scheduled routine for cleaning, maintaining and replacing hood filters in every commercial kitchen. The actual length of time between each deep clean, service and replacement will vary, depending on the condition of the individual range hood.

A ventilation hood over a busy restaurant kitchen may have filters that need to be replaced every six to eight months. However, that timeframe may shorten if the range hood, duct work and fan are not cleaned and maintained regularly.

The majority of commercial kitchen owners simply don’t have the available staff or resources to undertake such a detailed task. In fact, most eateries need their staff to focus on what they do best – cooking great meals and serving satisfied customers.

The easiest and most effective way to ensure that any kitchen’s hood, exhaust and ventilation system is operating at its best is to book a complete hood service and duct cleaning. Appointing a professional company to take care of the cleaning allows you to keep your staff focused on their jobs. You also have the peace of mind that the job is done properly and any faulty or damaged parts can be repaired or replaced quickly.

Fire Suppression Systems

Are Your Fire Suppression Systems Compliant?


Los Angeles, CA – Commercial kitchen facilities are required to uphold fire testing standard UL-300, a policy that has been in place since 1994. UL stands for Underwriters Laboratories, the organization that created the rules to help commercial kitchens deal with and control property and life-threatening fires.

To earn UL 300 certification, which is necessary to secure a Property Insurance policy, Underwriters Laboratories must test and certify each piece of fire suppression equipment independently. The goal is to help restaurants reduce the risk of fires by ensuring that all cooking equipment and the kitchen setup minimizes the collection of grease in the duct-work and the air. Fire extinguishing equipment must also be adequate in handling the severely hot temperatures that can be found in most commercial kitchen equipment.

UL-300 Certification

Before 1994, most commercial cooking operations used animal fat and deep fryers that were poorly insulated, resulting in inconsistent and inefficient cooking temperatures. In those days, kitchens used dry chemical systems that would smother a fire if one were to break out.

Modern Fire Suppression Systems

These days, kitchens have done away with animal fat and have instead turned to vegetable oils, which tend to heat to cooking temperatures more quickly. The deep fryers used in today’s kitchens retain heat more efficiently and are well-insulated. However, dry chemical systems are no longer used, as they are incapable of extinguishing fires and keeping them extinguished.

UL-300 calls for the use of wet chemical fire suppression systems, which serve two primary purposes. First, UL-300 systems still smother fires similar to the way dry chemical extinguishers did. Second, they are designed to cool the liquids so that the fire doesn’t re-ignite, something dry systems were unequipped to do.

UL-300 Requirements

If you hope for your commercial kitchen to pass inspection, the following requirements will need to be put into place.

  • Fire extinguishing nozzles should be located in all hoods and ducts, as well as above each cooking appliance.
  • All gas and electrical power sources should have automatic fuel shutoff capabilities.
  • A manual shutoff pull station should be available for all power sources.
  • You should have at least one wet chemical fire extinguishing system that adheres to UL-300 (and that is checked semi-annually by a certified professional).
  • All hoods and ductwork should be maintained and cleaned semi-annually by an authorized service company.
  • Grease filters should be cleaned on a weekly basis.

NFPA 96

NFPA stands for National Fire Prevention Association, an organization that works to prevent fires in commercial kitchens, and other cooking facilities. NFPA 96 is a publication that outlines the safety guidelines that restaurant owners can put in place to reduce fire risk.

The guidelines include the proper distance and angles for installing exhaust hoods and cooking surfaces, as well as what types of exhaust filters are acceptable for cooking equipment.

The publication also delves into the proper construction for ducts, including how large they should be, and what materials they should be comprised of. The angles at which they produce exhaust outside of the building are also covered.

While these guidelines may seem daunting, they’re actually good for you, the restaurant owner, as it takes much of the guesswork out of how to properly set up a commercial kitchen. They are also designed to keep your property, staff, and customers safe by preventing grease and other fires.
