The kitchen must be kept ventilated. "The kitchen must be kept ventilated for a long time." Pan Weimin, a professional in the safety management department of Wuxi China Resources Gas Co., Ltd. said that natural gas is lighter than air. In the kitchen. Liquefied gas is heavier than air, and if it leaks, it will settle to the ground and vaporize. If the kitchen is kept ventilated, it can float out.
Before going to bed and going out, you must close the valve. Many people save trouble. In daily life, only the gas cooker switch is closed, and the gas valve is not closed. Pan Weimin pointed out that natural gas users have a handle valve when entering the gas pipeline. This is the valve behind the meter, and there is a valve connected to the hose. This is the valve before the stove. Before going to bed, you must turn off the front stove valve. Do not think that you can turn off the gas stove switch. For personnel going out for a long time, be sure to close the front valve of the stove. For safety, it is better to close the front valve of the watch.
Repeated opening and closing, will the gas valve "slip" and there will be a large leak? Pan Weimin explained that the gas valve is a ball valve and there will be no "slip wire". If there is looseness and you are worried about damage or leakage, you can ask gas company personnel to come and inspect.
Don't rely on the gas alarm Some families are worried about gas leaks and have installed a gas alarm, so can you rest easy?
Pan Weimin believes that you cannot rely on gas alarms for paralysis. Gas alarms are sometimes misleading. If there are many smokers in the home, the gas alarm will also alarm. However, due to some reasons, gas leaks, and the gas alarm does not alarm, which may cause serious consequences. Some enterprises use gas alarms, and someone will regularly maintain the equipment to ensure its sensitivity. However, for household gas alarms, residents are unlikely to verify and replace the air-tight components in time to maintain them. Therefore, it is better for residents to increase their awareness of security, not to be paralyzed, and to be more responsible for themselves and their families.
It is strictly forbidden to use open flames to check for leaks. "It is strictly forbidden to use open flames to check for leaks. Do not try to use a lighter." Pan Weimin said that a simple and practical way to find gas leaks is to use a brush dipped in soapy water to the area where the leak is suspected Bubble, whether the bubble has swelled, if it is, it can be judged that there is a leak.
Another way to check for natural gas leaks is to look at the gas meter. Natural gas has a small molecular weight and is easy to leak. When gas leaks such as gas pipes and valves are suspected, firstly, all the burning appliances (such as stoves, water heaters, etc.) can be turned off. Observe the last digit of the gas meter, and carefully observe whether there is a long time. Walking phenomenon, if there is walking, there is air leakage. If residents cannot judge for themselves, they can also close the inlet valve in front of the gas meter, and ask the gas company maintenance personnel to check.
It is strictly forbidden to heat the liquefied gas cylinder for cooking and cooking. Only one dish is left. At this time, the liquefied gas is used up. In daily life, in order to "emergency", some people use hot water in a basin, put the liquefied gas tank in the hot water, and then turn on the stove to light the fire and continue cooking.
"It is strictly forbidden to use a heater or hot water to heat liquid gas." Pan Weimin pointed out that when the liquefied gas is heated, the gas will expand rapidly, and under high pressure, it will burst out of the cylinder and explode.
Pan Weimin also reminded that LPG cylinders should never be placed upside down or sideways. There are impurities in the liquefied gas. Upside-down or side-loaded liquefied gas cylinders will cause impurities to block the hose. If the hose is flushed in the blockage, the liquefied gas will quickly vaporize and explode in case of fire. In addition, such a placement may easily cause the hose to fall off and a gas leakage accident may occur.
What to do if a major gas leak is found?
"It is forbidden to switch on and off electrical appliances when it is found that gas is leaked. It is strictly forbidden to make phone calls and open flames to prevent combustion and explosion of the leaked gas." Pan Weimin said that residents should try to cut off the gas source and close the valve at the front of the meter to avoid leaking areas. Then call for help and ask a professional to deal with it.
It is worth reminding that when receiving a gas outage notice or finding a sudden gas outage, the gas equipment valve should be closed to prevent unburned natural gas from leaking into the room after the gas is supplied.
