Gas insurance needs to be bought. General gas insurance is cheap, and ordinary families with gas are fully capable of buying it. Due to the frequent occurrence of gas explosions, fires and other tragedies in recent years, it is very necessary to buy gas insurance. The staff of the price department said that when the new residents handled the opening of natural gas, they did not ask to pay the gas safety insurance premium, but only applied voluntarily. Gas companies mainly define the charging standard and coverage of gas insurance, and citizens can purchase it voluntarily if necessary.
