Natural gas has been accepted by the general public because of its advantages of convenient use, cleanliness, economy, energy conservation and environmental protection. The number of installation households is increasing day by day. However, many users lack knowledge of safe gas use and experience in emergency treatment in case of accidents. In order to reduce and avoid user safety accidents, you need to know these natural gas safety knowledge.

（1） If you smell a pungent odor, there may be air leakage.

（2） If bubbles appear at the joints of the equipment coated with soapy water, there may be air leakage. It is strictly prohibited to check the air leakage with open fire.

Treatment measures after indoor gas leakage:

（1） When you smell a smell of rotten eggs, you should be aware that it may be gas leakage. You can quickly open the doors and windows for ventilation. Do not switch on and off the electrical appliances. Go to the outdoor ventilation place as soon as possible to call the rescue phone of the gas company or call 110 for alarm. If the fire cannot be controlled, please leave the site quickly after evacuating personnel, and call the fire alarm "119" where there is no gas leakage.

（2） Cut off the air supply. Remember to "cut off the fire when the gas is cut off". Immediately close the valve in front of the stove and the main valve in front of the meter to put out the fire. If the fire is large and there is a flame near the valve in front of the stove, you can use a handful of dry powder to hit the root of the flame from top to bottom, or wrap your hands with wet towels and wet clothes, and try to close the valve.

Actively participate in gas safety inspection:

（1） The gas enterprise shall inspect the customer's gas facilities (indoor main valve, stove front valve, gas metering device and gas pipeline) at least once a year. The purpose of this paper is to find out the hidden danger of safety and prevent and reduce the occurrence of safety accidents.

（2） Cooperate with gas operating enterprises in pipeline safety inspection, maintenance and meter reading. Once potential safety hazards are found in gas facilities, cooperate with gas operating enterprises to implement rectification.
