How often does the state stipulate that the hotel oil fume pipeline should be cleaned?

The cleaning of oil fume pipes has become a fire topic of concern to catering units in the whole society. Light dust and environmental protection say you

Seeing this topic, someone will immediately say, "Two months!" Yes, as early as April 2007 1, Beijing Fire Bureau implemented the Regulations on Safety in Production of Catering Business Units in Beijing, which clearly stated that in order to strengthen the supervision and management of safety in production, improve the safety level of catering business units, prevent and reduce production safety accidents, and ensure the safety of people's lives and property, Article 25 stipulated that the smoke hood and flue entrance in the operation room of catering business units should be within 1 meter. And in the third paragraph of article 35, it is pointed out that those who fail to clean the oil fume exhaust pipeline on time shall be fined between 5,000 yuan and 30,000 yuan;

As early as 2003, the Beijing Fire Bureau issued the Notice of Beijing Fire Bureau on Strengthening the Fire Safety Management of Kitchen Chimneys and Oil Smoke Exhaust Pipes, stipulating that the cleaning frequency of oil smoke pipes in a unit should not be less than 1 time every quarter;

Since the promulgation of the "Notice", fires and other accidents have occurred frequently due to the failure of many units to regularly arrange oil fume pipelines as required. In the same year, the "Notice on Frequent Fires of Kitchen Oil Smoke Pipes" was issued, which once again emphasized the regular cleaning of oil smoke pipes.
