1, Ji'nan strengthen the ventilation hood according to the environmental conditions good ventilation facilities, because the kitchen gas work are exhaust hood, ventilation hood is relatively large, gas when the smoke hood in the smoke, can not consider the problem of kitchen ventilation. Just pay attention to the pipe closed, to prevent non work time poisoning.
2, according to the number of ventilation to determine the exhaust air: each kitchen is different, the kitchen area and kitchen utensils, stoves are not proportional to the number, the same stove produces pollutants and heat is also very different。 In fact, the kitchen ventilation is not comprehensive ventilation, ventilation rate by design, there will be a lot of error。
3, installation and testing equipment, regular inspection of gas pipelines and liquefied gas tanks and their components, but also regularly check, detect, alarm equipment, artificial regular inspection and testing equipment and use. To prevent detection instruments in the kitchen humidity, high temperature environment failure.
4, the size of the hood to determine the amount of air: the hood and the lower side of the stove between the intake area and the wind speed of the product to calculate the air flow is more appropriate。
5, local ventilation: for the storage of liquefied gas cylinder and households, gas warehouse, main control equipment to the firewall, closed gas leakage, and exhaust ventilation facilities, regular ventilation, or personnel into the open air.
