1. Do not pour flour near an open flame. Flour is very small dust particles that diffuse into the air when dumped. When a certain concentration is reached, even a touch of open flame can cause an explosion.

Do not spray insecticide when cooking with fire. All insecticide sprays have highly volatile and flammable solvents. The nanoscale spray like particles sprayed out spread very quickly, and only a small spark would ignite the explosive mixture in the air containing oxygen, which is easy to explode in case of open fire, spark or high temperature.

When the oil pan catches fire, immediately cover the pan and turn off the gas; Or cover with a wet cloth large enough. "If the fire is not very strong and it's a stir fry, just leave the pot off the stove.".

4. Do not put frozen food directly into an oil pan. Unfrozen frozen food is directly placed in a hot oil pan, and the ice on the outer layer of the food quickly turns into water vapor, causing the oil pan to boil immediately.

Do not use the microwave to heat eggs. Why can't you put raw eggs in the microwave to heat them? Because when we cook eggs, the heat is transferred from the outside to the inside, while using a microwave oven to cook eggs is the opposite. When the inside of the egg is heated and expanded, but the eggshell blocks the expansion of the gas, an explosion occurs.

6. Do not use a pressure cooker to cook sticky food such as porridge. It is best not to use a pressure cooker to cook beans, porridge, kelp soup, and other foods that are prone to clogging the center hole and safety valve vent holes; Do not use the pressure cooker beyond the time limit. The service life of the sealing rubber ring should not exceed two years. Regularly replace it. If there is any air leakage at the edge, immediately stop using and conduct maintenance.

When going out, be sure to check the gas valve to ensure it is closed.
