You must know that neglecting this can result in hefty repair costs and even the complete loss of your establishment. Poorly designed kitchen exhaust systems come with common issues such as inadequate access doors,\u00a0 proximity to heat or flammable materials, and multiple connections from different heat sources. These flaws ultimately result in serious safety hazards, especially in the event of a fire. Prioritizing proper system design is crucial for preventing risks and ensuring long-term protection.<\/span><\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_83 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/discounthoodcleaner.ca\/blog\/most-common-problems-with-kitchen-exhaust-systems\/#Here_are_the_most_common_problems_with_kitchen_exhaust_systems_Have_a_look_at_them\" >Here are the most common problems with kitchen exhaust systems.

It&#8217;s necessary for these access panels to be large and grease-tight to ensure thorough cleaning. They should be made from the same material and thickness as the ductwork. Plus, the access panels must be placed at least every 12 feet along horizontal ducts and within three feet of both sides of the fan.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In addition, if the necessary access panels are not in the kitchen exhaust system, it might not receive the required cleaning and maintenance to avoid the risk of fire hazards. In the long run, grease, oil and other flammable materials can accumulate in the hood, gutters, ducts and filters. Therefore, routine inspections and <\/span><a href=\"https:\/\/discounthoodcleaner.ca\/blog\/how-is-regular-cleaning-in-restaurants-the-key-to-food-safety-success\/\"><span style=\"font-weight: 400;\">regular cleanings<\/span><\/a><span style=\"font-weight: 400;\"> are necessary, and for that, you need to ensure that the access panels are large enough to enable a proper cleaning process.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_The_Grease_Remover_Positioned_Unsafely_Near_the_Heat\"><\/span>2) The Grease Remover Positioned Unsafely Near the Heat<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">When it comes to <\/span><a href=\"https:\/\/discounthoodcleaner.ca\/blog\/how-often-should-you-schedule-commercial-kitchen-hood-cleaning\/\"><span style=\"font-weight: 400;\">commercial kitchens<\/span><\/a><span style=\"font-weight: 400;\">,\u00a0 stovetops can often be the reason for unexpected flare-ups. If the ignition source is exceptionally close to the grease removal device, a small flame can quickly ignite a fire in the kitchen exhaust hood and ductwork. To prevent this situation, there should be a minimum of 18 inches distance between the grease removal device and the cooking surface, or 4 feet for charcoal broilers. It&#8217;s vital to protect grease removal devices from direct flames and combustion gases to maintain fire safety and reduce the risk of dangerous kitchen fires.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Multiple_Vents_Connected_To_Different_Sections\"><\/span>3) Multiple Vents Connected To Different Sections<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">As your restaurant expands or undergoes layout changes with time, the kitchen exhaust systems may get extended or added in different ways. One thing that needs to be considered is that commercial kitchens with multiple heat sources should be allowed to share the same duct system. Moreover, kitchens in isolated compartments should have independent systems with dedicated fire-isolated ducts, shafts and fans.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The utilization of cooking equipment such as charcoal heaters or wood-fired ovens poses a higher fire risk, making it even more crucial for these operations to have their own ventilation systems. Consequently, proper design and separation are essential to maintain safety and prevent potential hazards.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_Risky_Materials_Positioned_Close_To_Ventilation_Systems\"><\/span>4) Risky Materials Positioned Close To Ventilation Systems<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">In order to prevent serious fire hazards, it&#8217;s crucial to utilize fire-resistant construction materials and ensure proper separation between exhaust ducts and combustible elements. Also, fire insulation must be installed between the ducts and any nearby combustible surfaces, especially where they pass through fire-rated floors, walls, or ceilings, to prevent any threats.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In addition, to maintain the safety of the building, all these components must be installed, typically requiring a fireproof covering around the ductwork. Also, one should never use ducts and hoods as storage or shelving. Clear signage should be placed nearby to remind staff of the fire risks and the importance of keeping these areas transparent.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_Maintenance_Duties\"><\/span>5) Maintenance Duties<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">In multi-level buildings or mixed-use facilities, maintenance of a commercial kitchen\u2019s exhaust system and ductwork is generally a shared responsibility between the kitchen operator and the building owner. It&#8217;s the job of the building owner and the kitchen operator to properly take care of the <\/span><a href=\"https:\/\/discounthoodcleaner.ca\/blog\/why-should-restaurant-owners-prioritize-kitchen-exhaust-cleaning\/\"><span style=\"font-weight: 400;\">kitchen exhaust system<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Since the exhaust hood and filter are located near the kitchen, while the duct and fan are typically in the main building, clear communication and coordination are essential to ensure proper maintenance and cleaning. Both of them are responsible for keeping the system in safe working condition. However, the primary responsibility for the fire safety of the entire premises is of the building owner.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"In_Conclusion\"><\/span>In Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">It is important that you understand all these potential issues that could occur with the kitchen exhaust system.
