Why Are Kitchen Extraction Systems Considered a Fire Hazard? Kitchen extraction fan systems are especially vulnerable to fire due to the constant accumulation of grease, oil vapours, and carbon deposits inside the ductwork. During cooking, these combustible substances coat the internal surfaces of the system and can ignite from open flames, hot surfaces, cooking equipment, …
Kitchen extraction fan systems are considered one of the highest-risk areas within a building’s ventilation network. Unlike standard ventilation ducts, these systems operate in demanding environments where grease, oil vapours, heat, and airborne particles are constantly drawn through the ductwork during cooking. Over time, these contaminants build up on the internal surfaces of the system, …
Every time food is cooked, airborne grease particles and steam travel through the extraction system, gradually coating the inside of the ducts. Over time, these deposits harden into thick layers of grease, restricting airflow and creating unpleasant odours. More importantly, they present a serious fire hazard. Without regular cleaning, grease accumulation can turn an extraction …
