Kitchen extractor hoods can pose a significant fire hazard, especially if not cleaned properly. The problem is primarily caused by grease accumulations in hard-to-reach areas. As these grease layers become thicker, they can easily be ignited by heat sources, creating a potential fire hazard.

Furthermore, grease accumulation leads to reduced system efficiency, resulting in increased energy consumption. This can have negative consequences for both the economy and the environment. At the same time, the working environment deteriorates, as poor ventilation can create unhealthy conditions for kitchen staff.

The increasing insurance losses due to kitchen fires have led to recommendations to clean extractor hoods regularly, preferably every six months. This measure aims to minimize the risk of fire and ensure a safer working environment. The implementation of such preventive measures is essential to protect both employees and property from the serious consequences of kitchen fires.
