Hidden dangers of residents' gas safety and preventive measures

With the rapid development of urban pipeline gas industry, a large number of gas pipelines enter communities and residents' homes. This is undoubtedly a good thing, which will bring benefits to improve economic efficiency, reduce urban air pollution and facilitate residents' lives. However, various factors that follow make a large number of gas hidden dangers exist. Let's take a look at the hidden dangers and preventive measures of residents' gas safety.

1 Residents' gas safety hazards and preventive measures, user operation or illegal operation.

Misoperation or illegal operation will bring serious security risks and often turn into accidents, and the lesson is very profound. For example, on April 12, 2009, the owner of Shuiyunjian Store in Fortune Building, Heping Road, our city failed to turn off the switch on the first day after using the cooker, resulting in gas leakage. When I opened the door the next day, I smelled gas. The male shopkeeper turned off the valve, and the female shopkeeper turned on the electric light because she didn't know the common sense of gas safety, causing serious burns. Another example is 65438+20041October 27th.

A gas explosion in a room of Shenzhen Huiqiao New Village caused a fire, causing 2 deaths and 5 injuries. At the beginning of gas supply, residents installed three links, one connected to the cooker and the other was free to eat hot pot. On the night of October 27th, 65438/kloc-0, an elderly couple, the person in charge of the room, mistakenly opened the control interface when closing the valve behind the meter, and a large amount of gas leaked. Because the leaked liquefied petroleum gas in the room met the fire source and exploded instantly, which led to the tragedy. Therefore, for gas valves that have not been used for a long time, you should apply to the gas company for temporary plugging to reduce misoperation during operation; Residents who are not at home for a long time should entrust relatives and friends or property companies to contact the gas company, so that technicians can come to the door for security inspection in time, close indoor valves and eliminate hidden dangers.

2. The problem that the valve is not closed well or not closed well after using gas.

For example,1On the evening of July 7, 999, a resident of Zhejiang Wenfu Building turned off the switch of the minimum fire level after using the cooker, mistakenly thinking that it was dead; And the valve behind the table is not closed, air leakage accumulates at the bottom of the cabinet, forming mixed gas within the explosion limit, and burning waste paper on Mars will lead to deflagration accidents. Another example is September 2 1 2004, when a resident of Jinlai Building moved in the morning, he didn't turn off the valve in a hurry, and a lot of gas leaked. Fire officers and soldiers, the property management company and our company personnel took urgent action together, closed the main valve of the riser on the roof, and climbed into the household from its neighbor Tujia Yangtai for treatment, thus avoiding an accident. Therefore, every time after cooking and boiling water, especially before going to bed or when there is no one at home, the valve should be closed in time.

3 the hose is too long or the hose is aging

According to statistics, 90% of the accidents of residential users are due to the long aging of rubber pipes, and small rubber pipes caused by improper use will lead to major accidents. Gas accidents caused by aging or falling off of gas hoses occur from time to time all over the country. There have been many gas accidents in many places in our province. For example, in a project in June, 2006, Sunjia in Jian 'an District, Zhengzhou City suffered from gas leakage due to the aging of trapped rubber hose, which caused Sunjia's face to burn and the window glass in his home was shattered by the explosion gas wave. On March 29th, 2006, a household in Nanguan Street, Zhengzhou City was cooking with gas, and the kitchen was bombed because of a gas pipeline leak. According to regulations, natural gas hoses should be replaced after 18 months. In order to prevent gas leakage caused by aging of rubber hose, it is recommended that you regularly check whether the rubber hose is aging and replace it in time if necessary. The rubber tube should not exceed two meters. When using, the hose should not be too close to the stove fire to avoid being deformed by heat. Fix the hose connector with a pipe clamp, and be sure to close the valve in front of the furnace when not in use.

4. The user's unauthorized installation, modification or spontaneous combustion.

For example, in June 5438+1October 65438+April, 2008, gas users in the southwest corner of our city changed their kitchen into a bedroom privately, buried aluminum plastic pipes in the kitchen (bedroom), and built the kitchen from the middle hall to the back of the house. One night, the gas riser leaked, causing the Cui couple who were sleeping in the kitchen to be hospitalized for gas poisoning. Therefore, it is forbidden for any individual or non-professional construction unit to connect pipeline gas by itself. No matter installation, modification or ignition, it must be completed by professionals of the gas company. Users must not covet temporary convenience or cheapness and cause accidents.

5. Cylinder gas and pipeline gas are mixed or used in series.

For example, in August 2000, a resident in Xialupu, Wenzhou, mixed cylinders and pipeline gas in series, which was cheaper? As a result, the nanny opened the wrong valve during operation, resulting in a large amount of liquefied petroleum gas leakage. Fortunately, it was handled properly and did not cause a big accident. Therefore, users should use a single gas source, either pipeline gas or cylinder gas. Users of high-rise buildings must use pipeline gas according to fire regulations, and cylinders and bottle groups are prohibited.

6. Problems caused by poor ventilation conditions

For example, on April 4, 2009, a young woman in the relatives' hospital of Chaoyang Road Mine Construction in our city used a smokeless gas water heater to take a bath without opening the window for ventilation, which led to incomplete combustion and the tragedy of suffocation and death. Because gas combustion consumes a lot of air, it is necessary to maintain good ventilation conditions to prevent incomplete combustion, especially when it is cold in winter and several people in a family take turns taking a bath.

7. The problem of gas facilities being occupied and destroyed in the community.

For example, on May 3, 2004, the low-voltage coil on the roof of a building was broken, and the risers and some coils of buildings B and C were suppressed by users' illegal buildings. It turned out that the user built an illegal building and managed the plates on his daughter's wall in the wall. During the decoration, the impact drill broke the coil. For example, in the early morning of February 1 2005, due to the irregular operation of the excavator on the site, the gas pipe broke and the gas caught fire for more than an hour before it was put out. Therefore, municipal gas facilities and public gas pipelines must be effectively protected. Once you find anything unusual, contact the gas company immediately.
