"Cooling artifact" or "hurting the weapon"?A variety of cooling spray is not marked with flammable and explosive

Recently, it has encountered continuous high temperature weather in many places. Under the hot sun, some items inside the car, even the heat and cooling products, can become a dangerous goods and cause accidents.

Burned during driving

The cooling spray is a "murderer"

At noon on June 25 this year, a white private car suddenly stopped in the middle of the road, and the items on the car were scattered. The police rushed to the scene and found that the two of them were panicked, and their cheeks, arms, and other places were severely burned. At this time, there was no bright fire in the car. What exactly did the two be burned?

It is understood that at that time, a net red spray that could be "freezed" in the car. Recently, the reporter searched on the e -commerce platform and found that the spray products of the slogan "Swelling, Quick Cooling" are seen everywhere, and some products have sold more than 10,000 a month. In the publicity video of the online store, the hot seat after the sun was easily sprayed with this "summer artifact", and the entire car was immediately frozen. Are these sprays so amazing?

The reporter purchased three products with the highest sales volume and brought them to the Chongqing Fire Brigade for experiments. Under the scorching sun, the outdoor temperature exceeded 38 ° C. The firefighters sprayed the three spray onto the fresh leaves. The surface temperature of the leaves quickly dropped below 0 ° C, and a layer of white frost was cited.

Huang Run, a firefighter for the Chongqing Fire Rescue Captain Life Division: We found that the most obvious effect can be instantly reduced to about minus 30 degrees Celsius, and a large area of ​​black spots appear on the leaves.

The subsequent car seat spray experiment also shows that these products can quickly drop the seat temperature from about 40 ° C to below 0 ° C.

How can such a "cooling artifact" become a "wounding weapon"? Firefighters simulated the people in the car to ignite when they used it, and found that the three sprayed white gas fogs were found. When they encountered bright fire, they immediately turned into the flames of the bears.

If they spray them on the skin, what happens when they encounter bright fires? Firefighters found three pigskin to simulate human skin. After spraying three types of cooling spray, the pig skin could be directly ignited. The severe burning flame quickly ignited the surrounding hair and continued to spread.

Huang Run, a firefighter for Chongqing Fire Rescue Captain Life Division: In the case of outdoor wind, the burning process of each pig skin lasted for more than five seconds. It can be seen that a large area of ​​burnt areas appeared on the pig skin. If it is ignited in a closed space in the car, it may occur, and the burns caused by human skin may be more serious.

Spray a lot in the car to cool down

The consequences of the fire are amazing

The reporter noticed that in some online store promotional videos, claiming a large amount of spraying in the car can quickly reduce the temperature of the entire carriage and emphasize "physical cooling 0 harm". Is this really the case?

Firefighters found a scrapped car for simulation test. In order to achieve the effect of cooling the entire carriage, firefighters sprayed a lot of cooling spray inside the car and windows. At this time, what would happen once in the car ignition smoking? Firefighters conduct simulation tests after safety protection. I saw that Minghuo was close to the vehicle, and a violent explosion occurred in the car.

The explosion not only caused the rear window glass to be blown up instantly, but the back row of the private car also burned a fire. Firefighters quickly found the fire extinguisher fire, and the car was still beyond recognition. In the event of someone in the car, the consequences are unimaginable.

What are the ingredients of these sprays, and why is there such a huge explosion power? The reporter carefully looked at the instructions of the three products, and found that two of them did not explain the ingredients. Only one said with cooling factor, edible fragrance, solvents, etc.

Professional instrument analysis ingredients

Open the "secret" of the cooling spray "secret"

None of the two cooling spray is not marked. What is the so -called cooling factor? The reporter found the Chongqing University Analysis and Test Center, using professional instruments to analyze product ingredients to see what secrets these cooling spray hidden.

Chongqing University Analysis and Test Center's temperamental use instrument can accurately analyze the composition and content of the spray. After testing the three cooling spray products, the experiment found that this black car special cooling spray was found. The main component was a substance called methar ether. The other two cooling spray contains the same three substances.

Qin Shijiang, an engineer of Chongqing University Analysis and Test Center: Two of the three products of the three products are propane, isopylene and orthopedane. It is actually a common liquefied petroleum and gas in our lives. The content is more than 90%. Explosion. The other content is mainly methyl ether, with more than 95%. Meethyl is also a flammable and explosive gas, which contains neurotoxicity. If a large amount of inhalation is prone to suffocation.

爆 ingredients

The packaging is not marked

According to reports, this type of cooling spray is to store these flammable and explosive gas stored in a metal tank by pressing liquefaction, and quickly vaporize and absorb the surrounding environmental heat to achieve rapid cooling. More than 90%of the flammable and explosive ingredients, but the three products are not mentioned, and similar situations are not individual.

Recently, the Shanghai Municipal Consumer Protection Commission commissioned professional institutions to evaluate 10 such hot -selling products on the Internet and found that four of them did not indicate product components. For the flammable testing of the product, four of the 10 samples were 90 cm away from Minghuo, which can be quickly ignited. It is a type of flammable product. The distance of more than 15 cm should be indicated that the two types of flammable logos should be marked, but no packaging appears.

Duan Road, senior engineer of the Shanghai Chemical Research Institute of Chemical Engineering Institute: According to relevant standards, flammable liquid and gas solution should be clearly identified and prompting their flammable categories in the product label. The situation is more common. Even if you don't encounter Minghuo

It will explode at high temperature

Such dangerous products, even if they do not encounter bright fires, there are huge risks to stay in the car in high temperatures. At about 12 noon on the same day, Chongqing's outdoor temperature exceeded 38 ° C. Firefighters conducted three spray -in -car storage experiments.

After the door was closed, about 25 minutes, a bottle of blue cooling spray exploded first. A circular burst of about 20 cm in diameter was blown on the windshield, and the spray next to it was also bounced. After 7 minutes, another cooling spray left on the instrument also exploded.

Will the bounce black cooling spray safety be higher? Firefighters subsequently found three common high -pressure spray products in life, including air fresh agents, sunscreen spray and hydrating spray, and put into the car with a new black cooling spray in the car for a comparison test. Under the scorching sun, the temperature of the inner instrument platform exceeded 80 ° C, and the black cooling spray insisted on the first explosion for only 23 minutes.

Not only did the windshield exploded a large hole, but the spray next to it was also blown up instantly.

Qin Shijiang, an engineer of Chongqing University Analysis and Test Center: This kind of product is more dangerous than the cosmetics spray and moisturizing spray we usually use. Because the cosmetics spray contains a lot of water, this category is almost composed of pure flammable and explosive gas, which is easier to explode.

Under the hot sun at high temperature

Be careful of the items in the car "self -exploding"

In addition to the flammable and explosive cooling spray, the common mobile phones, charging treasures, aromatherapy and other items in the car may also become dangerous goods at high temperatures. High -temperature weather should be particularly careful.

At more than 3 pm on July 24th, the monitoring probe at a house at Fuzhou, Jiangxi recorded such a scene. The man in white was planning to go out by the electric vehicle, and the silver car parked next to him suddenly made a loud noise, and the white mist spread in the car. Just as the man looked back, the explosion occurred in the car, the windows were blown up directly, and the huge flame quickly surrounded the vehicle. Fortunately, the man ran away quickly and avoided it.

After receiving the police officer, the firefighter rushed to the scene, and the two water guns were dispatched to completely extinguish the train. After many days of investigation, the culprit of the explosion was finally locked.

Kang Xin, a firefighter at Yan Shu Avenue, Fire Rescue Detachment of Fuzhou City: According to the owner, a fragrant ornament was placed on the private car windshield of the private car that day. After our investigation, this explosion was mainly due to the sudden explosion of flammable aromatherapy after exposure, which caused the entire vehicle to explode.

At noon on August 3, a silver van was spontaneously ignited under the scorching sun in a community in Jiuhukou County, Jiangxi. The van driver who was delivering the goods remembered when he saw the fire, and a lot of flammable products were put on the car.

The fire spread rapidly. When the fire rescue workers completely extinguished the fire, the two cars were burned only to the skeleton. The first fire car cabin to get angry is even more unrecognizable.

Yang Yong, a fire supervisor of the fire rescue brigade of Hukou County, Jiujiang City: After the inspection of the on -site investigation by our brigade, the fire was charged by the owner in the car, causing the fire to charging the fire.

Sudden fire in the car

The cause is the charging treasure

Three days later, a private car in Jinghai District, Tianjin suddenly smoked under the scorching sun, and residents of the community immediately called the police. Fire rescue workers rushed to the scene and found that the entire carriage was covered by thick smoke and continued to smoke from the gap between the carriage. The initial judgment was that the car was caught in the car, but the owner was never seen.

In order to prevent the fire from spreading, the firefighters continued to spray water and cool the body. When the owner rushed to the opening door, he found that the position of the co -pilot was launched. After the danger was completely lifted, the firefighter found a charging treasure that had been burned from the co -pilot seat.

Li Zhiguo, Chief of the Comprehensive Guidance Division of Tianjin Jinghai District Fire Rescue Detachment: After asking the owner, he left a charging treasure at the co -pilot when he got off the car. At that time, the charging treasure was not charged, but under the high temperature conditions in the car, the charging treasure was spontaneous, causing the combustible material on the car.

How dangerous is the charging treasure in the car? The simulation experiments conducted by Lianyungang Fire found that at a temperature of 35 ° C, the temperature in the car would exceed 50 ° C. After ten minutes of exposure, the charging treasure shell placed on the instrument began to soften, and a large amount of white bubbles appeared. After about 20 minutes, the charging treasure began to smoke on the side, and quickly emerged from the flame.

The fire department reminds the public that at high temperatures, do not put flammable and explosive items such as lighter, high -pressure spray, carbonated beverages, perfumes in the car, and use a closed environment in the car to use alcohol -containing ingredients such as flower dew and disinfection spray. Stay away from Minghuo, pay attention to safety.
