With the development of economy, the coverage rate of gas in our country is also rising. City gas can bring great convenience to our life, but once it is used improperly or negligently, it is very easy to cause gas safety accidents; once the gas leak leaks, it is easy to cause serious accidents such as gas poisoning, gas explosion, fire and so on. How to nip in the bud? What should be paid attention to when using gas?

First of all, we should develop good living habits

One is in the use of gas, to keep the kitchen window ventilation.

Second, when cooking, someone should take care of it to prevent the fire from going out without knowing it due to overflow of soup, resulting in gas leakage.

Third, do not hang debris on the gas pipeline

Fourth, if you do not use gas for a long time, remember to close the front valve.

Fifth, the gas pipeline should be inspected regularly every year. Once a gas leak is found, it should be repaired in time and parts should be replaced in time. The usual service life of gas hoses is2Years, in order to ensure safety, every2to be replaced once a year.

Second, find the gas leak, take the right measures.

One is to quickly close the main air source valve (table front valve), quickly open all the doors and windows in the home, reduce the content of gas in the air, let the gas emitted to the outside, so that the air circulation.

Second, it is strictly prohibited to turn on or off any electrical appliances or use the telephone, cut off the total outdoor power supply, and extinguish all kindling. When a gas leak is found, do not move all kinds of power switches. Especially when the smell of gas is found when sleeping and waking up at night, people get up and are used to turning on the lights first. At this time, the lights must not be turned on. Because when you switch the power switch, sparks will be generated. At this time, there is a large amount of gas in the room and in the switch, so the consequences can be imagined. Similarly, when the light is on, if a gas leak is found, the switch cannot be turned off. Quickly call the service phone or repair phone outdoors to find out the cause of the gas leak.

third, once an open fire is triggered,Put out the fire quickly. with a fire extinguisher,Dry Powderextinguishing agent2. Wet quilts, etc. hit the root of the flame to extinguish the fire quickly. After the fire is completely extinguished, close the valve. Remember not to close the valve before the fire is extinguished. When the fire is on, directly closing the valve may lead to backflow and explosion.IfIf the fire is serious, if the fire cannot be controlled, it should leave the scene quickly after evacuation.Gas leakageThe place to callFire 119Call the police and immediately report the insurance to the customer service center of the gas company. At the same time, family members and neighbors should be evacuated quickly, and irrelevant personnel should be prevented from approaching.

How to prevent gas leakage?

It is recommended to purchase a gas leak alarm and place the alarm at home. When the gas leaks, the alarm will give an alarm so as to find out the cause of the gas leak in time and take timely measures. However, the core device of the alarm is a gas detection sensor.recommend a compositeDouble gas sensorTGS3870, the sensor pairCO/CH4Such flammable gases have good sensitivity and are a good choice for household gas leak detection.
