Why are gas accidents frequent?
Analysis of the cause of the accident, mainly because a small number of users did not pay enough attention to the protection of gas facilities and equipment. Non-professionals violated regulations and arbitrarily changed gas equipment. After an accident, they did not know how to take emergency measures, resulting in gas leakage, fire, Consequences such as explosions, causing property damage and personal injury.
Other residents are not aware of safety and lack the ability to use gas properly and after problems occur. It has caused some accidents that can be avoided. For example, if the aging gas facilities are not replaced in time, the hoses are aging and falling off, and the fire is improperly used. When the water is boiled, the fire is extinguished to cause air leakage. After the air leaks, the air is not ventilated in time, or the ventilation is insufficient to use the telecommunications facilities to cause an explosion.
With the improvement of residents' living standards, the threat of home decoration to gas safety is becoming more and more prominent. Users have serious problems changing the gas pipeline and equipment in the household. It is very common for users to privately change private gas pipelines and private gas facilities during renovation. In the past three years, we have counted newly developed gas users, and 70% to 80% of users have privately modified indoor gas. Pipeline facilities, construction workers lack gas common sense, do not have construction qualifications, causing air leaks, leaving hidden dangers.
How to avoid
Let's bring common sense to the safe use of natural gas. In order to avoid natural gas liquefied gas accidents, please study carefully.
1. For rooms that have access to natural gas, users are not allowed to use other fuels, such as bottled liquefied gas and coal.
2. The length of the natural gas hose should not exceed 2 meters. The rubber pipe must not pass through the wall and go through the room. It should be inspected regularly and replaced regularly. It is found that the hose is aging, cracked, tortuous or damaged and needs to be replaced in time. Expired hoses are strictly prohibited.
3. The gas appliance must be switched to the closed position after each use; it must be confirmed that it is in the closed position before each use.
4. When cooking, the kitchen must be taken care of by anyone at any time to prevent the soup from overflowing and extinguishing the fire, resulting in leakage of natural gas.
5, before going out to bed and going to sleep at night, keep in mind the valve before closing the gas source. If you do not need a burning appliance for a long time, be sure to close the front valve.
6. In case of sudden interruption of gas supply, the gas appliance switch and the front ball valve should be closed at the same time until the street is normally supplied with gas, before continuing to use.
