Your method is very correct, and I recommend six more ways to prevent gas poisoning, I hope you are satisfied.

1.Prevent gas leakage in gas pipes and gas cooktops. Before going to bed, check whether the gas switch is turned off properly and whether there is a peculiar smell of gas leakage in the kitchen.

If there is any suspicion, soapy water can be applied to the suspected air leak, if there is an air leak, soap bubbles will bubble in the inspected area. Do not use ignition to detect whether there is a gas leak, because when the gas content in the air reaches 5% or 40%, it will explode in case of open flame.

2.Prevent gas from being extinguished after ignition and causing a large amount of gas leakage. When cooking, boiling water, simmering soup, boiling medicine, etc., someone should supervise it, and never leave the kitchen to do other things after lighting the gas.

3.Use a gas water heater properly. It is required that the water heater must be installed in a well-ventilated environment, preferably not in the bathroom. When taking a bath alone, someone else should take care of it to prevent the flame of the water heater from going out and causing air leakage.

4.Use the gas stove correctly. When using the gas stove to cook and cook, be sure to turn on the range hood.

5.Maintain good indoor air circulation. Although the carbon dioxide produced by the combustion of coal gas is not as toxic as carbon monoxide, when the carbon dioxide content in the air reaches 1%, it will be harmful to people. When it reaches 4% to 5%, people will feel headache, dizziness, and wheezing; When it reaches 10%, it can make people unconscious, respiratory arrest and even death.

Therefore, indoor ventilation should be maintained throughout the year.

6.Do not place flammable or explosive materials next to the gas stove.

Generally speaking, as long as the natural gas stopcock valve is turned off, there will be no gas leakage, it is better to open a little window, your practice is already very safe, no problem at all, and it will not be poisoned.
