This is the scene when the "shop" is inside the fire.
There are huge potential safety hazards in the “three-in-one†shops for production, operation, storage and storage. How terrible is the "three in one" store? On the morning of August 2, the Ningbo Fire Brigade organized a street fire experiment along the street, and the results were shocking.
For this experiment, the fire department deliberately chose an abandoned street shop, re-arranged, and truly reproduced the "three-in-one" shop: the front hall is the customer's consumption department, the back hall is the kitchen, and the gas tank is placed on the ground. The trachea is connected to the stove; through the narrow wooden stairs to the second floor, there is a bedroom, no windows and people must bend over. The reason why I chose to experiment here is because there is a similar fire that killed one death and four injuries a month ago.
At 9:36 in the morning, the experiment officially began, and the debris piled up in the “shop†aisle suddenly caught fire, and the smoke suddenly filled. The monitoring equipment placed indoors shows that in just 30 seconds, the kitchen and the aisle are occupied by thick smoke, and some of the monitoring screens are not clear. At this time, the indoor temperature continuously climbed from the original 34 ° C, to 40 seconds, some of the cameras could not withstand the high temperature burned first, the screen turned black and directly showed the words "no network video". At the same time, the thermometer can not stand the "firepower" stopped at the upper limit of the temperature display.
By 1 minute and 08 seconds, all the camera screens had only white smoke and flare, and the oxygen concentration in the shop dropped from the initial 18.9% to 13.6%, while the carbon monoxide concentration increased from 0.1 ppm to 27.0 ppm. The fire still burned. After 3 minutes, all the cameras in the shop were burned and could no longer be displayed. The oxygen concentration was 0.0%. The impact of this "fire" on the outdoor is not small, although the fire department prepared in advance, but the outside is still full of smoke, and the smell of smoke is very horrible.
"A three-in-one shop fire like this has a short time to escape, basically only one minute. At this time, if a person is asleep in the attic and realizes that the situation is wrong and wants to escape, it is often because of the wooden stairs. The fire is not going down, and the window is closed, and it is finally blocked by the 'blocking'. Upstairs, Guo Yaozhen, the staff of the Yuyao Fire Brigade, said that the fire department found that there were quite a few shops along the street during daily inspections. In the event of a fire, the consequences are unimaginable. They hope that the public will pay attention to it through experiments, especially those who operate shops, and must pay attention to fire prevention.
“We also arranged an escape experiment. This 'shop' installed a free-standing smoke alarm, a life-saving descending device and a split-type security window. The smoke bomb simulates the scene after the fire, and the fire officers and soldiers open in the attic. The combined anti-theft window, the downward-opening security window bar as a 'ladder', and finally use the life-saving descending device to escape smoothly." Guo Haijun said.
