Whether to close the gas valve before or after turning off the stove can affect the safety of using the gas stove. However, not everyone understands this clearly.

Closing the gas cylinder valve when not in use is a safety principle that every family using a gas stove must know. However, even if you have used a gas stove for many years, not everyone knows whether to close the gas valve before or after turning off the stove.

Closing the gas valve before or after turning off the stove?

The answer to this question is to close the gas cylinder valve first and then turn off the stove.

The reason for this is explained as follows: When cooking, gas will move from the tank through the pipe, wire and then to the burner. After the gas in the tank is locked tightly, a certain amount of excess gas will still remain in the pipe. This amount of gas has gone out of the tank and if not used up, when the right conditions arise, it can cause a fire or explosion.

This method ensures that all gas in the pipe is consumed, helping to avoid waste and ensuring safety, without sudden flare-ups when turning on the stove next time.

Some notes when using a gas stove to ensure safety

- Buy a gas cylinder from a reputable company or dealer: The quality of the gas cylinder determines the safety when used. You should buy a gas cylinder at reputable stores and dealers to ensure that the gas is filled according to the correct procedure and the correct weight on the shell. When buying, pay attention to the gas cylinder. The shell must be intact, not scratched, and the details must not be dented or rusted.

- Place the gas cylinder in a well-ventilated place: Gas is heavier than air, so when it escapes, the gas will spill to the ground. Therefore, if the gas tank is placed under the kitchen cabinet, this position needs to be well-ventilated. The gas tank should be placed 1-1.5m away from the stove, avoid placing it directly under the gas stove. The door of the gas tank cabinet must always be open or left open for easy observation, avoiding the situation where rats nest inside the gas tank cabinet or gnaw on the gas pipe.

– Clean the stove regularly: During use, you need to clean the stove regularly. If the stove is old or rusty, it should be replaced to ensure safety. The gas valve and gas pipe need to be checked regularly to detect cases of valve leaks, punctured pipes... causing gas to leak out. With gas pipes, it should be replaced after 3-5 years of use.

Gas is colorless, odorless, and tasteless, but the manufacturer has added additives so that users can easily detect the smell of gas if there is a gas leak. When you smell this smell, absolutely do not turn on the light or fire to check the gas tank. Gas is very flammable. If you turn on the light, lighter, or cell phone, it can create a spark and cause the gas to ignite immediately. At this time, you should open all the doors to let the air circulate, the gas will automatically escape, reducing the gas concentration in the kitchen.
