The exhaust air from the kitchen shall be cleaned as sufficient as possible over the place of generation by an aerosol separator accommodated in the hood. The aerosol separators shall be easily accessible， easy-to-demount and cleanable in a dish washer. To this end they shall be made of chromium nickel steel only. The rate of flow recommended by the manufacturer for the separator shall be kept. Knit fabric filters and plug-on grille filters as the only aerosol separators shall not be used. The exhaustion hoods in the kitchens which are arranged on top of kitchen equipment and used to collect vapor and steams quickly shall be designed such that a sufficiently high retaining capacity is achieved. Kitchen exhaust air hoods shall at least 0.2 m protrude over the circumference on top of the kitchen appliance. If the lower edge of the hood is higher than 2.10 m on top of the floor， a higher protrusion shall be provided (angle of opening = 12° from the edge of working areas). Collection chutes shall be free from burr and arranged such at all sides that they can be drained via drains. Hoods of chromium nickel steel with integrated lighting only shall be used as exhaustion hoods. If outdoor air lines to kitchens or other rooms are passed through fire sections， they shall be equipped with suitable and approved fire protection flaps or the pipeline shall be provided with a fire protection lining from the outlet of the room. The fire protection flaps used shall be tested and approved for the relevant case of application. Exhaust air channels shall be made of fire-resistant material. Specific measures are required for the use of gas heated large-size kitchen equipment in order to ensure the necessary supply of combustion air on the one hand and to ensure reliable exhaust gas dissipation on the other. If kitchen exhaust air and exhaust gases of gas appliances are fed off commonly， an additional safeguard shall be provided. This safeguard shall switch off the gas fired equipment if the exhaust air system fails. The high exhaust gas temperatures shall be taken into account when selecting the hood structure. In any case， gas equipment shall be operated only if the room air system is in operation.
