When the gas is turned on, it is required to write an insufficient commitment letter to buy insurance.

Because the responsibility is clear. Gas suppliers ensure that users understand the potential risks of gas use. When the gas is turned on, it is not compulsory to buy insurance. If you don't buy insurance, you need to sign a letter of commitment to clarify the attribution of responsibility. When there is a problem, the user can't shift the responsibility to the supplier before opening the air to the residents.
