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.
