At about 4:50 am on December 2, an owner of the home on the 17th floor of Building 2, Building 2, Lifeng Union New City Community, located at the intersection of Electronic Street and Yanhuan Road, suddenly exploded, killing one person.
At the scene, the reporter saw that the window of the household was blown up. According to the community security, the elevator door on the 17th floor was also blown up. Some people suspect that the explosion may be related to natural gas, and the cause of the current incident is under investigation.
After the start of winter heating, in order to keep warm, the number of indoor ventilation windows is reduced, and the natural gas in the kitchen is easy to accumulate when leaked. In addition to air drying, it is easy to generate static electricity, which increases the risk of flash explosion.
Proper use of natural gas-related equipment, reasonable avoidance of safety hazards, regular maintenance can ensure the safety of the owners.
â—†Problem & Hidden Danger: The hose is aging, the gas meter is hidden, and the valve is closed after the stove is closed.
In response to the safety of household gas use, the Huashang Daily reporter conducted a random range of random investigations and found the following hidden dangers:
A random survey by reporters found that most households ignore the problem of rubber tube aging
"My natural gas pipe has not been replaced since the renovation, and I have looked good, but I don't know if I need to replace it?" asked Ms. Wang.
In the investigation, the reporter found that there are not a few readers who do not replace natural gas pipes for several years. “The natural gas pipeline is generally recommended to be replaced once every 18 months. We also regularly check the safety of households in each residential area for safety hazards. We will find that the problem will be reminded or corrected, but there are still many families who do not pay attention. If it is not replaced for a long time, it is very It is prone to aging of the hose, which will cause gas leakage accidents," said an inspector at Xi'an Qinhua Natural Gas Company.
Gas meters and water heaters are hidden and difficult to find
The reporter found that many families hide natural gas meters and pipes for the sake of beautiful decoration. Other kitchens use cabinets and wall cabinets to place gas water heaters in the cabinets.
A staff member of the water heater in the forest said. "This looks beautiful, but it is not standardized and it is not safe. According to the regulations, natural gas meters and pipes must be exposed outside, gas water heaters can not be installed in a confined space, they must be kept ventilated, so that it is not easy to happen. Explosion accidents. There are still many families who do not pay much attention to the later inspection and maintenance when using embedded gas stoves. After a long time, the joints are loose, the hoses are aging, and the peeling is not easy to be seen. Once the gas leaks, it is difficult to find.
After cooking, you should close the valve and then close the stove, but most readers have misunderstandings.
“Every time I finish the meal, I don’t have to close the stove before closing the valve. I have been using it for many years.†Regarding the closing sequence of the cooker switch and the gas valve, Ms. Cheng Nan said that she was surprised.
According to the household inspectors, there are not a few readers who are not using them like Ms. Zhang. They have been using such misunderstandings for many years. In fact, the correct method should be: first close the gas valve and then turn off the cooker, so that the excess gas in the pipeline can be fully burned, and the pipeline will not store gas, posing a safety hazard.
In addition, the in-house inspectors also reminded that in the case of traveling or no one at home, the gas main valve should be closed to avoid potential safety hazards.
â—†Precautions: The hose should be replaced regularly, the qualified products should be purchased, and the product should not be used when using it.
The gas pipeline of Ms. Wang’s house is connected to the gas stove placed above the cabinet through the cabinet. Recently, Ms. Wang found that there was a smell of gas leakage after opening the cabinet. When the staff went to the door for maintenance, it was found that the connection between the pipe and the stove was loose. Slow leaks.
The gas hose is not too small through the hole. The length of the hose should not exceed 2 meters.
Mr. Wang Li, the head of the marketing center of the Xi'an area, said that when the owner passes the pipe through the cabinet, the reserved pipe through the hole has a larger diameter, which is convenient for the airtight ventilation of the closed cabinet. At the same time, the cups and spoons placed in the cabinet should also be careful not to touch the gas hose to avoid loose joints.
When selecting a hose, pay attention to the length of 1 m to 1.5 m, and the longest should not exceed 2 m.
Rubber pipes must not pass through the wall and should be inspected regularly. It is found that the aged cracks should be replaced in time. The rubber hose should not be used for more than 18 months, and the metal hose should be replaced once every 5 years.
Use natural gas equipment, don’t care, there are 5 points to pay attention to.
Consumers should pay attention to product quality when purchasing gas stoves, wall-hung boilers, water heaters, etc., and must have product certification and safety instructions, with obvious warning signs.
Wang Li said that in addition to purchasing qualified products and regular maintenance, the use of natural gas equipment such as gas stoves should also pay special attention to:
1, can not leave people when using gas, always pay attention to the stove fire to ensure safe use of gas.
2. If there is no fire for three consecutive times during ignition, stop for a while and make sure that the gas dissipates and then re-ignite. Because the stove has not been lit, but the gas has been released several times, it is very easy to accidents when exposed to open flames.
3. During the use of the cooker, if it is found to be extinguished, immediately turn off the switch, open the door and window to ventilate, and after the odor disappears, find out the cause of the flameout, and re-ignite after proper treatment.
4, do not use gas cookers in the absence of care, especially soup, porridge, milk and other foods are easy to overflow, to be taken care of to avoid spilling soup water to extinguish the fire, causing gas leakage.
5. At the end of the use of gas, pay attention to the habit of cultivating “fire and let goâ€. Check the use of gas before use, before going to bed, and when going out.
