A kitchen canopy, also referred to as a kitchen hood, exhaust hood, or range hood is a common feature in both domestic and commercial kitchens. Placed above equipment such as ovens and fryers, canopies work to remove all airborne 'contaminants' produced as a result of cooking, funnelling steam, heat, smoke, and grease out of the kitchen environment through a system of ductwork and fans.
Though canopies are generally highly useful in the maintenance of a safe, comfortable kitchen environment, they may become a fire risk where poorly maintained and allowed to harbour grease and fat deposits. For this reason, many regulatory bodies and insurance providers stipulate that commercial kitchen canopies should be cleaned to TR-19 standards by accredited professionals on a basis suited to usage levels.
