At 11 o'clock on the morning of October 13,
A snack bar in Xinyang Road, Ehu Town, Xishan District, Wuxi City
A gas explosion has occurred.
By 17:00 that day, the rescue work was over.
Cleared by search and rescue,
The accident caused a total of 9 deaths and 10 injuries.
▲Explosion moment
After this happened,
One about
After the gas is on fire, is it the first fire extinguishing or the first to close the valve?
Aroused a lot of attention from netizens.
In the video,
A person wearing a white uniform claimed that
After the gas explosion,
Fire and then close the valve.
Many netizens said that they "subvert common sense."
Problem video
In response, the Emergency Management Department Fire and Rescue Bureau announced on the 13th that the "professionals" wearing white clothes in this video are not firefighters (the following video interpreters), and the content of his explanation is also problematic. The gas tank is on fire. If the valve is in good condition, be sure to close the valve first.
↑↑↑This white uniform is not a firefighter!
Is this true?
Please don't be misled!
Emergency Management Department Fire Rescue Bureau official microblogging @中国消防 timely release authoritative answer:
Once the liquefied gas cylinder is on fire,
Can be based on the situation on site,
Take different disposal measures:
The first
In the case of a liquefied gas cylinder valve intact, the first choice is to close the valve, and the valve is extinguished when the fire is turned off. The situation of “fire first, then shut off the valve, otherwise it will ignite and cause an explosion” that is circulating on the Internet will not occur when the liquefied gas cylinder is on fire. Only when the gas pipeline is on fire, if the valve is quickly closed, the pressure in the pipeline will drop rapidly, and the pressure outside the pipeline will be greater than the pressure inside, and the fire will be pressed into the pipeline to cause tempering. When the firefighters are on fire in the disposal gas pipeline, they will first slowly close the pipeline valve to the minimum state, and then reduce the flame to a minimum, then close the valve to extinguish the fire. This is to prevent tempering. The liquefied gas cylinder has a small bottle body and a small bottle mouth. Relatively speaking, the pressure is small, no pressure difference is generated, and the pressure inside the liquefied gas cylinder is larger than the outside.
Second
If the valve of the liquefied gas cylinder that is on fire is damaged, it is not necessary to extinguish the fire. First, the liquefied gas cylinder is placed in an open area and placed, and then the bottle is cooled by water, waiting for the liquefied gas to burn out; if the liquefied gas cylinder is burned, it is in the household. Can not be transferred, well ventilated and there is no burning material around, you can first extinguish the fire, then use a wet rag and other items to block the bottle mouth, and send it to a professional liquefied gas station for disposal.
The firefighters who rushed out of the fire with their gas tanks were the common name of the media. This is a helpless situation when the valve is found to be broken when the valve is closed. If the valve is broken, it will not dare to extinguish the fire. Instead, it is better to carry the fired gas can to the blank zone, put it upside down to let it burn out, and controllable combustion is relatively safe. Because once the fire is extinguished, unburned gas will continue to spurt, or cause gas poisoning, or any fire or static electricity will cause a real explosion!
Third
If the liquefied gas cylinder is burned down to the ground flame, the cylinder is easily heated by the flame. After reaching a certain temperature, the liquefied gas in the bottle is thermally expanded, and the bottle body is prone to physical explosion. Once again, in the case of unpredictable and non-disposable ability, you should call 119 for the first time, wait for the firefighter to come to the scene, and do not let the burning bottle fall to the ground.
There are some seemingly credible "rumors" in the market that are misleading our lives. If it is about the safety of life and property, it is terrible. In fact, there is no need to entangle, as long as the gas stove at home is no problem, after the meal, directly turn off the gas. If you need to go out for a long time, remember to turn off the gas valve. Focus on the authoritative release, learn the knowledge of fire protection, and the Jiangjing fire extinguisher that is always safe and environmentally friendly at home is the king!
for safety
