If you notice a gas leak, do not turn on the lights or do anything that may cause an electric spark, but open the windows firstTherefore, when using gas, be sure to prevent gas leakage!

Therefore, ordinary switches can indeed ignite the mixture of gas and air in a gas leakage environment of a suitable concentration, resulting in an explosion. For the same reason, it is also not possible to make a phone call at the scene of a gas leak.
The mobile phone itself does not have an explosion-proof function, and the radio frequency sparks generated by the mobile phone can easily cause explosions in flammable and explosive areas, leading to disasters. Therefore, mobile phones are generally not allowed to be used in gas stations and other flammable and explosive places, unless they are explosion-proof mobile phones. For example, the explosion-proof mobile phone ioutdoor F1 (explosion-proof version) can be applied to oil, gas and other scenarios, but ordinary mobile phones cannot.
Gas is a flammable gas, when the house is full of gas, a small spark will cause an explosion, and turning on the light will also produce sparks, so do not turn on the light when the kitchen gas leaks, so as not to cause an explosion accident. If the gas leaks, we can't use appliances or turn on lights. Because gas is a flammable gas, if it leaks and reaches a certain concentration in the air, it may explode in case of fire. >>>More
3.Use soapy water to inspect indoor gas pipes for leaks.
If the concentration is large, if there is a starting power supply in the middle of the exhaust fan, it will explode, including metals, such as metal door locks. It is necessary to wait for the window to be scattered and the concentration will be reduced.
: Gas leaks explode at a certain concentration (0531), which is incredibly powerful.
Fire prevention measures for the use of gas: indoor gas pipes should not be located in a humid or corrosive medium room, and anti-corrosion measures should be taken when they must be laid; Indoor gas pipes should be made of galvanized steel pipes, and should not pass through bedrooms and bathrooms, if they must be crossed, casing should be added; The gas meter should be installed in a well-ventilated place indoors, and it is strictly forbidden to install it in bedrooms, bathrooms and places where chemical hazardous crystals and combustibles are placed; Gas stoves shall not be used in basements or uninhabited rooms in Hezhi; The hose should not be used for the balance connection between the gas furnace and the pipeline, and if it must be used, its length should not exceed 2 meters, and both ends must be firmly fastened. After each use, the valve at one end of the pipeline should be closed tightly to prevent air leakage; If a gas leak is found, ventilation measures should be taken immediately, and the gas supply department should be notified for maintenance.
