Emergency Science Popularization: It concerns thousands of households! You must master these gas safety knowledge

Safety first, the alarm bell is always ringing

Prevention is the key, and gas has become a necessity in life. However, once a gas explosion occurs, it is very likely to seriously endanger the safety of people's lives and property. How to determine whether there is a gas leak?

What should I do if I find a gas leak? The first thing to do with gas is to prevent leaks and repair them as soon as possible if any abnormality is found. In addition, you must remember these knowledge↓↓↓

01

Smell - use your nose to smell

Generally, domestic gas supply is treated with odor (ethyl mercaptan) to make the gas smell like rotten eggs, which makes it easier to detect leaks. So once you notice a similar odor in your home, it may be a gas leak.

02

Look at the gas meter

When no gas is used at all, check whether the number in the last red box of the gas meter moves. If it does, it can be determined that there is a leak behind the gas meter valve (such as the hose and interface between the stove and water heater connecting the gas meter).

03

Apply - spray with soapy water

Mix soap or washing powder with water to make soap liquid, and apply it to gas pipes, gas meter hoses, cock switches and other places prone to gas leakage to check whether there is a gas leak. If there is a gas leak, the soap liquid will be blown into foam. When you see foam generated and increasing, it means that there is a gas leak in that part. For extremely small leaks, it may not be observed, and the test results of professional detection tools should be used as the standard. What should I do if I find a gas leak?

1. Ventilate immediately

Close the valve and report to the relevant department to find out the cause; repair the leak in time to avoid a serious accident. It is especially important not to open the exhaust fan for ventilation in a hurry, ignoring that the exhaust fan is also powered. Open the window immediately for ventilation.

2. Do not turn on or off any electrical appliances

The connection of various electrical switches, plugs and sockets will generate sparks. When the flammable gas leaked indoors reaches a certain concentration, it will cause an explosion. Therefore, you should immediately cut off the power supply at the outdoor switch.

3. Do not put on or take off clothes indoors

Putting on and taking off clothes will generate static electricity, especially for blended and nylon fabrics. Static electricity can also detonate a certain concentration of flammable gases in the air.

4. Do not use telephones or mobile phones

When powered on, tiny sparks may be generated inside telephones and mobile phones, which may also cause explosions. You should stay away from the scene before calling for help. What should you do if you find someone suffering from gas poisoning? Once you find someone suffering from gas poisoning, you should immediately open all doors and windows in the room, turn off the gas appliance switch, leave the room and go outside to breathe fresh air or oxygen; those with severe symptoms should quickly leave the poisoning environment with the help of others, go outside to breathe fresh air or oxygen, and call 120 for emergency treatment as soon as possible. If breathing and heartbeat stop, artificial respiration and external cardiac compression should be performed on the spot. If conditions permit, it is best to go to a hospital with a hyperbaric oxygen chamber for rescue and treatment.
