Answer: Rooms or kitchens equipped with gas devices and facilities such as gas meters, gas stoves, and gas pipes must never be used as bedrooms or lounges, because if these devices and pipes are damaged and start leaking, it is difficult to detect the issue, which increases the risk of explosions, fires, and other hazards. 2. Why is it dangerous to use gas without supervision? Answer: When using gas, one should not leave the area and must keep an eye on the burning process at all times to adjust the flame. Because the sauce may spill and extinguish the flame, or when a low heat is used and the flame is blown out by the wind, the continued release of gas can cause accidents such as explosions and fires. 3. How to conduct safety checks when stopping the use of gas? Answer: Before going to bed, before leaving home, and when stopping the use of gas, it is necessary to check the gas switches to ensure that they are all turned off; the valves should be closed whenever no one is around. 4. What to do if a leak is detected? Answer: If you detect a gas smell indoors, you should immediately open the doors and windows, and check whether the gas stove switch is turned off If it is already turned off, there may be a leak in the gas pipeline or at the gas meter; in such cases, the main valve located before the gas meter should be closed immediately, after which one should go outside to call the gas company’s staff to come and inspect the situation. When gas users are away and the home is unoccupied, they should turn off the main switch in front of the gas meter to ensure safety. 5. What safety prohibitions should be noted when a leak is detected? Answer: In the event of a leak in a gas branch pipe and the user is unable to shut off the gas supply by themselves, they should immediately contact the gas company. Until the repair crew arrives, the user must not remain inside the premises; all sources of ignition must be kept away, and lights should not be turned on to avoid triggering an explosion. 6. How to detect a gas leak? Answer: Gas is an invisible and colorless gas that cannot be seen with the naked eye. However, for the safety of daily gas use, a special odorant is added to the gas so that leaks can be detected promptly. If users detect a strange smell in their home, they should check whether there is a gas leak. To locate gas leaks, apply soapy water to the gas meter, stoves, and pipe connections; wherever bubbles form, that is where the gas is leaking. Remember not to use an open flame during the inspection. 7. What are the hazards of storing items near gas meter stoves? Answer: Do not pile up combustible items such as waste paper, plastic products, dry wood, gasoline, bamboo baskets, and other debris around gas appliances like gas meters, gas stoves, and water heaters. This is to prevent fire accidents caused by discarded unextinguished matchsticks after the gas is ignited, as well as to avoid hindering maintenance work. 8. How to adjust the flame? Answer: When using a pot to cook food or a kettle to boil water, it is necessary to adjust the flame as needed, based on the size of the bottom surface of the pot or kettle and the intensity of the heat required; the flame should not extend beyond the area of the pot’s or kettle’s bottom surface. For electric stoves, adjust the air flap between the burner and the stove body so that the flame is blue, bright, and strong. Avoid having too weak a flame, which would waste the gas supply; a too weak flame also results in insufficient air intake and leads to backfire in the form of bubbles. 9. Is running a gas stove with no cooking a waste? Answer: When using gas, make sure to turn it off once it’s used up; light it again only when needed. Do not let the gas burn without use, nor waste gas just to avoid hassle. 10. What happens when the flame is exposed to wind? Answer: When the flame is exposed to wind, it will tilt to one side or sway, causing heat to spread and affecting combustion. It is best to make a wind shield out of metal sheet, depending on the size of the stove opening, or to use an old washbasin by removing its bottom and covering the base of the pot with it. This will prevent the wind from blowing out the flame, while also allowing the flame to burn more intensely, thus making full use of the gas and saving it. 11. How to use the gas stove switch? Answer: Turn on the gas supply switch, push it manually to rotate it 90 degrees counterclockwise; once a \"click\" sound is heard, the burner should have a flame. If no such sound is heard, reverse the movement and repeat the process. Once the desired setting is reached, release your hand. At this point, the burner’s intensity is reduced by 90° to the minimum level, and it can be adjusted further upward to completely cut off the gas supply. 12. The function and usage method of the gas meter switch. Answer: The gas meter switch is a valve used when maintaining the stove; it should be turned on in the morning and turned off at night. Use it regularly to prevent rusting, so as to ensure it functions properly in case of emergencies. The usage method is: when the switch handle is parallel to the gas pipe, the gas is turned on; when the switch handle is perpendicular to the gas pipe, the gas is turned off. 13. Maintenance of gas stoves. 1) The stains on the surface of the gas stove should be cleaned regularly to prevent rust. 2) The burner nozzles can easily get clogged with soup residue and dust; they can be cleared regularly using wire or an old toothbrush. 14. Handling of gas pipelines during interior decoration. 1) When encountering gas pipelines during interior decoration, approval must be obtained before any modifications can be made. 2) Gas pipelines are components that are prone to corrosion and leakage. Many users bury the pipelines inside walls (or the floor) during renovation, making it difficult to inspect them, which poses a serious challenge to proper maintenance. Therefore, users are required to expose the gas pipes indoors during decoration, so that any leaks can be addressed promptly and gas usage safety can be ensured. 15. Other precautions. 1) Children should be regularly taught not to fiddle with the valves, hoses, and other gas-related equipment of gas stoves, to prevent the valves from being damaged or being forgotten to be closed, which could lead to gas leaks. Children should also be taught not to play by hanging on exposed gas pipes, to prevent leaks caused by loose pipe connections. 2) It is strictly prohibited to use gas on an empty flame to dry clothes, bed sheets, baby diapers, etc., to avoid burning the clothes and causing a fire. 3) Gas stoves, water heaters, and other combustion appliances must not be used in rooms with closed doors and windows, nor in environments with poor air circulation. 4) No items should be hung on gas facilities such as gas pipes and gas meters, nor should ropes or wires be used, to prevent leaks caused by loose pipe connections. It must be specifically emphasized that gas pipelines must not be used as grounding wires for electrical equipment, and welding on gas pipes is prohibited to avoid accidents. 5) After the installation of gas facilities is completed and formal acceptance is obtained, the gas company shall be responsible for conducting a trial ignition; private attempts at ignition are prohibited. 6) Users must not extend the gas hose without permission. The length of household hoses should not exceed 2 meters, and both ends of the hoses must be secured with clamps. Users must not connect or extend the hoses on their own, as an increased length of the hoses raises the likelihood of damage and air leakage. Older gas hoses should be replaced in a timely manner.
