Summary of gas usage misconceptions such as gas equipment, gas usage habits, emergency operations
Gas is one of the most commonly used energy sources in our daily lives. Cooking, bathing, heating... all rely on the use of gas. Gas safety is the first priority. Today, we have listed common gas usage "misconceptions" for you. You can compare and self check to see if you have avoided them~
1. Misunderstandings in gas usage - Gas equipment section
Misconception 1: As long as the gas appliance at home is not broken, it can be used continuously.
Many users may think that gas appliances in their homes, such as gas stoves, gas water heaters, etc., can be used continuously as long as they are not damaged, but little do they know that gas appliances also have a "service life". The "Safety Management Rules for Household Gas Combustion Appliances" stipulate that the scrapping period for household gas combustion appliances is 8 years from the date of sale. The use of gas appliances that have exceeded their service life is not only inefficient, but also poses safety hazards.
Correct practice: When purchasing gas appliances, users should pay attention to checking their production date and service life. After reaching the end of its service life, even if the equipment still looks intact, it should be replaced with a new gas appliance in a timely manner. In addition, regular maintenance and upkeep of gas appliances should be carried out to avoid the use of damaged or aged gas appliances.
Misconception 2: To save gas and money, install windproof covers, energy gathering rings, and other fire and wind prevention devices on gas stoves.
Some users may purchase "kitchen appliances" online claiming to have the functions of gathering flames and saving gas, such as windproof covers and energy gathering rings, in order to save energy and money. However, in reality, once this "windproof cover" is used, the sealed device hinders air circulation, resulting in insufficient oxygen supply and "incomplete combustion", which not only reduces thermal efficiency but also poses safety hazards.
Hidden danger interpretation: Natural gas combustion requires oxygen to assist combustion. Household gas stoves can supply oxygen through downdraft and updraft on the stove surface. However, the unauthorized installation of a "windproof cover" on a gas stove can block the intake passage, resulting in a severe shortage of incoming air supply on the stove surface, leading to incomplete combustion and the production of toxic gases such as carbon monoxide, which can cause safety hazards such as poisoning. At the same time, insufficient combustion of gas can affect the thermal efficiency of gas stoves, consuming more gas when cooking or cooking. And using a "windproof cover" on a glass stove may cause uneven heating of the glass panel, resulting in panel cracking or breakage, posing a safety hazard.
Correct practice: According to the requirements of the "Gas Engineering Project Specification", "household users should not install devices or accessories that may affect the performance of gas appliances other than factory products on gas appliances without authorization." For your gas safety, please do not install devices or accessories that may affect the performance of gas appliances without authorization; Do not purchase products without labeled product name, factory name, address, qualification certificate, specifications and models of applicable stoves, usage instructions, and safety precautions.
Misconception 3: Gas companies install inherently safe accessories for the purpose of charging fees.
Some users may think that installing and using safety accessories at home is not very necessary, and even consider it a means for gas companies to charge fees. But in fact, essential safety accessories such as gas shut-off valves and metal hoses can effectively ensure the safety of household gas use. For example, the service life of metal hoses is up to 8-10 years, and they are corrosion-resistant, rodent resistant, and have high safety performance. The self closing valve has automatic shut-off protection functions for overpressure, undervoltage, and overcurrent. When the gas in the pipeline exceeds or falls below a certain pressure, or when the hose falls off and causes an abnormal increase in gas flow rate, it will automatically cut off to protect the safety of users' gas use.
Correct approach: During the gas company's home inspection, safety accessories such as self closing valves and metal hoses should be installed for users. Users should actively cooperate with gas workers' home inspection, install safety accessories, and jointly protect the safety of household gas use.
2. Misunderstandings in Gas Usage - Gas Usage Habits
Misconception 1: Repeatedly starting a gas stove when it cannot ignite, or using a lighter to assist combustion.
Incorrect interpretation: When the gas stove valve is opened and the gas is released, the concentration of natural gas in the air will increase. If one repeatedly ignites or uses open flames such as matches or lighters to assist combustion, it is easy to ignite the trapped gas in the air, thereby causing danger.
Correct practice: If the gas stove cannot ignite, it may be due to the gas stove being left for too long or the ignition needle being contaminated with oil. Users can clean and wipe the oil on the ignition needle before ignition. If it is determined that the ignition function of the stove has failed, the manufacturer should be contacted for repair as soon as possible.
Misconception 2: When adjusting the flame of a gas stove, adjust the firepower in reverse.
Incorrect interpretation: Some users may turn down the flame of the gas stove clockwise when adjusting it. However, when the flame is turned down to a certain extent, the gas output cannot meet the combustion conditions, and the flame will extinguish. At this time, the escaping gas will scatter into the home, which can easily lead to serious consequences.
Correct method: Adjust the firepower of the stove by turning the knob; When the knob is turned counterclockwise to 90°, the stove's firepower is at its maximum. Continuing to turn the knob counterclockwise gradually reduces the firepower from maximum to minimum. When the knob reaches its maximum angle, the firepower is at its minimum.
Misconception 3: When using a gas stove to cook soup and stew for a long time, there is no need to keep an eye on it. Simply turn down the gas flame.
Incorrect interpretation: When using gas to boil water or soup, there is a risk of the gas flame being extinguished by the soup or blown out by the wind if no one is watching over it, which can cause gas leakage and easily lead to accidents such as fires and explosions.
Correct practice: Remember not to leave people when using fire in the kitchen, and always pay attention to the combustion situation and adjust the flame when using gas.
Misconception 4: When cooking, casually place food packaging boxes, plastic bags, and other items next to the gas stove.
Incorrect interpretation: Paper boxes, plastic bags, etc. are flammable materials that can pose a danger when placed around gas stoves.
Correct practice: It is prohibited to place flammable and explosive materials around gas stoves and pipelines, and various paper boxes, plastic bags, and other items should be properly placed.
Misconception 5: When turning on the air conditioner in hot weather, to prevent the cool air from escaping, close the doors and windows tightly when using gas.
Incorrect interpretation: Gas combustion consumes indoor oxygen levels. For example, closing doors and windows tightly can lead to a decrease in indoor oxygen levels, which is not only detrimental to combustion but also causes harm to human health.
Correct practice: When using gas stoves, it is necessary to ensure indoor air circulation and sufficient combustion, which not only saves gas but also ensures gas safety. But attention should be paid to avoiding abnormal phenomena such as incomplete combustion or flameout caused by strong winds blowing directly.
3. Misunderstandings in Gas Use - Emergency Operations
If there is a suspected gas leak in the user's home, do not perform the following operations:
- Misconception 1: Use an open flame to check for leaks.
- Misconception 2: Quickly open doors and windows for ventilation.
- Misconception 3: Turn on the range hood to exhaust.
- Misconception 4: Call for help at the scene of indoor gas leakage.
The above method is highly likely to cause further danger. Please do not turn on or off any electrical appliances such as range hoods and exhaust fans; Never operate various electrical switches, plugs, and sockets; Never make phone calls indoors, including mobile phones and landline phones; Never wear or take off clothes indoors to avoid static electricity.
The correct approach should be:
- Close the valve in front of the meter;
- Slowly open doors and windows for ventilation. When opening windows for ventilation, the action should be light and slow to avoid sparks caused by friction, impact, etc;
- Go to an open and safe place outdoors and call the gas service hotline for repair.
