After taking a shower, be sure to close the air inlet valve of the gas water heater. Be calm when you find gas leakage, immediately close the gas meter door, cut off the gas source, and quickly open the doors and windows for ventilation.

When applying for repair, the wiring personnel should be informed of the home address, contact information, site conditions and the cause of air leakage. After the maintenance is completed, the residential property management department should also be informed, and the open flame should not be near the air leakage area.
