Yes It is clearly pointed out in the "Regulations on Safety Management of Household Gas Burning Appliances" issued by the state that the safe service life of household artificial gas cookers is 6 years and that of natural gas cookers is 8 years. Over-age use has great potential safety hazards, including "failure of flameout protection, accidental air leakage, aging of parts, air leakage, poisoning and explosion, deflagration and tempering".

Service life of range hood: Many consumers are not clear about the service life of range hood. The national standard for household kitchen equipment stipulates that it will be scrapped in 7 years. However, about 30% of the range hoods currently in use are over-aged. After the range hood is over-aged to a certain number of years, a large amount of oil pollution that cannot be cleaned will be deposited inside. In the cooking process, carcinogens harmful to health may be produced after heating, and may be inhaled by people during cooking, which is easy to endanger health.
