Oil hits the pan at high temperature and turns to vapour and fine droplets that the exhaust pulls straight up.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Tossing and flaring.<\/strong> Stir-frying throws oil and sauce into the air and into the flame. Flare-ups push grease-laden vapour into the hood in bursts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Sticky ingredients.<\/strong> Soy, oyster sauce, hoisin, sugar and starch do not just coat the hood. They bake on and harden into a residue that is harder to remove than plain oil.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Deep fryers next to the wok line.<\/strong> Many Chinese kitchens run fryers for items such as spring rolls, dumplings and crispy dishes, which adds even more grease to the same exhaust.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Long operating hours.<\/strong> Lunch, dinner and late-night service mean the system runs hard for most of the day.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Where_the_grease_goes\"><\/span>Where the grease goes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Grease does not stay in the hood. It travels through the whole system:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Baffle filters:<\/strong> These catch the first layer and clog fast on a wok line.<\/li>\n\n\n\n<li><strong>Plenum:<\/strong> The space behind the filters collects heavy buildup that you cannot see from the kitchen.<\/li>\n\n\n\n<li><strong>Ductwork:<\/strong> Horizontal runs and elbows trap grease. This is the most dangerous place for buildup, because a fire here can spread through the building.<\/li>\n\n\n\n<li><strong>Rooftop fan:<\/strong> The fan is the most skipped part of the system. Heavy wok grease often overflows onto the roof, which is both a fire risk and a roofing problem.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_often_should_a_wok_kitchen_clean_its_hood\"><\/span>How often should a wok kitchen clean its hood?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">NFPA 96, which the Ontario Fire Code references for commercial cooking exhaust, groups wok cooking with high-volume operations. Those are on a <strong>quarterly<\/strong> cleaning schedule at a minimum.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td>Setup<\/td><td>Typical interval<\/td><\/tr><\/thead><tbody><tr><td>Wok line, charbroiling or high-volume cooking<\/td><td>Quarterly (every 3 months)<\/td><\/tr><tr><td>Wok line with 24-hour or very heavy use<\/td><td>Quarterly, or more often if the inspection shows buildup<\/td><\/tr><tr><td>Moderate-volume Chinese kitchen, limited wok use<\/td><td>Semi-annually<\/td><\/tr><tr><td>Solid-fuel cooking such as a wood or charcoal roaster<\/td><td>Monthly inspection<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">If you see heavy grease at your filters or access panels before three months are up, clean sooner. The inspection decides your schedule, not the calendar. Confirm the exact requirement for your kitchen with Toronto Fire Services or your insurer.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_cost_of_waiting\"><\/span>The cost of waiting<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most wok kitchens we meet are on a semi-annual or yearly schedule that is too long for their cooking. Waiting costs you in several ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fire risk:<\/strong> Grease in the ducts is fuel. A flare-up at the wok can ignite buildup you cannot see.<\/li>\n\n\n\n<li><strong>Insurance:<\/strong> A claim can be disputed if the exhaust was not maintained to the required standard. Keep every cleaning report.<\/li>\n\n\n\n<li><strong>Failed inspections:<\/strong> Visible grease on filters, access panels or the roof is easy for an inspector to spot.<\/li>\n\n\n\n<li><strong>Weak ventilation:<\/strong> A clogged system pulls less air, so smoke and heat stay in the kitchen and your cooks feel it.<\/li>\n\n\n\n<li><strong>Roof damage:<\/strong> Grease overflow can stain and damage the roof membrane, which is a repair bill for your landlord and a dispute for you.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Warning_signs_your_wok_exhaust_is_overdue\"><\/span>Warning signs your wok exhaust is overdue<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Grease dripping from the hood or filters<\/li>\n\n\n\n<li>Thick, sticky residue you can feel on the hood interior<\/li>\n\n\n\n<li>Smoke staying in the kitchen at the wok line<\/li>\n\n\n\n<li>Grease marks on the roof around the exhaust fan<\/li>\n\n\n\n<li>A fan that is louder or slower than it used to be<\/li>\n\n\n\n<li>A strong burnt oil smell after service<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">If you see two or more, book a cleaning this week.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_a_proper_wok_kitchen_cleaning_includes\"><\/span>What a proper wok kitchen cleaning includes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Heavy wok grease needs more than a surface clean. A proper service should cover:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hood interior and plenum degreased and rinsed<\/li>\n\n\n\n<li>Baffle filters removed, cleaned and reinstalled<\/li>\n\n\n\n<li>Full duct run cleaned through accessible sections, including horizontal runs and elbows<\/li>\n\n\n\n<li>Rooftop exhaust fan cleaned and the grease containment checked<\/li>\n\n\n\n<li>Access panels installed where the duct cannot be reached<\/li>\n\n\n\n<li>Floors, equipment and the wok line protected during the work<\/li>\n\n\n\n<li>A written report with before and after photos, and a service sticker<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Ask to see the photos of the duct and fan, not just the hood. If the cleaner cannot show you the duct, it was probably not cleaned.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_your_kitchen_team_can_do_between_cleanings\"><\/span>What your kitchen team can do between cleanings<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Professional cleaning is not a replacement for daily habits, but good habits stretch the time between services.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Clean or swap filters often.<\/strong> On a wok line, filters should be cleaned far more often than the rest of the system.<\/li>\n\n\n\n<li><strong>Empty grease cups and drip trays daily.<\/strong> Do not let them overflow.<\/li>\n\n\n\n<li><strong>Wipe the hood interior you can reach<\/strong> at the end of each night.<\/li>\n\n\n\n<li><strong>Report any grease on the roof<\/strong> to your cleaner right away.<\/li>\n\n\n\n<li><strong>Keep fire suppression nozzles clear.<\/strong> The wet chemical system over the wok line must be inspected by a certified technician on its own schedule.
