Toy guns and gunpowder are prohibited from illegal use
Goose palm explosion tracking
The reporter was informed that the 2008 "3·13" explosion accident in Huangpu had a striking similarity with the accident of the goose-casting explosion.
The culprit in the "3·13" accident was a trailer truck (plate number èµ£ J49571) from the container transportation branch of Pingxiang Shenzhou Automobile Trading Co., Ltd., which was shipped from Liuyang, Hunan (31 tons). Cap" (pump gun with gunpowder). For similar products, the State Administration of Work Safety has stated that “violation of use is prohibitedâ€.
The mixture is easy to explode instantly
The reporter found that the main raw material of the round plastic firing cap "(the gunpowder for guns) is generally a mixture of potassium chlorate and red phosphorus, which is also the bullet material for the starting gun used in sports games.
Yesterday, Professor Liu Xiaoping of the School of Chemical Engineering of Hunan University of Science and Technology said that after the strong oxidant potassium chlorate is mixed with the strong reducing agent red phosphorus, it can be reacted violently by impact or strong heat, and it will explode and burn to produce high heat. Such a mixture is a very sensitive explosive. Generally, a tight package with a package of less than one gram can make a huge sound as long as it falls to the ground.
"From the scene of the explosion and the scope of the explosion, the site must have accumulated a large number of flammable and explosive materials. Due to the detonation of local explosives, in the instantaneous chain reaction, the remaining large number of explosives also exploded. Liu Xiaoping told reporters that the principle of the explosion is that the solid or liquid instantly turns into a gas, and the volume of the space suddenly expands, thus generating a huge amount of shock waves. In many areas, the variety of firecrackers that have been popular during the Chinese New Year is the use of this mixture.
The reporter also searched online for a number of explosion experiment videos about the mixture. The video content shows that some primary and secondary school students can even conduct related experiments because of the wide range of raw materials.
In a video from Youku's name "Phosphorus Potassium Chloride Red Phosphorus Impact", the reporter saw that several middle school students packed a mixture of potassium chlorate and red phosphorus into a small paper bag and placed it on the ground. Then, a student started with a hammer from a position ten centimeters from the ground and slammed the paper bag vertically. As the hammer fell, a glare sparked in the paper bag, and the paper bag was blown up with the sound of the explosion. Smash.
In another video from the 56-network name "Explosive reaction of potassium chlorate and red phosphorus", a middle school student, a mixture of potassium chlorate and red phosphorus, adhered to the bottom of an empty beverage bottle, and then forced to throw a little further away. Immediately, a huge explosion and glare were emitted, and then numerous fragments of Mars and burning bottles were seen, falling from the sky with white smoke.
Potassium chlorate should be immediately stored on site as soon as it is discovered
At the same time, the reporter was informed that many fireworks and firecrackers in China have illegally stored and used potassium chlorate to produce fireworks and firecrackers, resulting in frequent explosions.
In 2006, the State Administration of Work Safety issued a series of documents such as the “Notice on the Prohibition of Violation of the Use of Potassium Chlorate to Produce Fireworks and Firecrackersâ€, and banned the illegal use and storage of potassium chlorate and derivative products.
The notice requires that the fireworks and firecrackers flow and potassium chlorate purchase, sale and use registration management system be implemented, and the potassium chlorate fireworks and firecracker products and the potassium chlorate source traceability system should be established to curb the illegal use of potassium chlorate to produce fireworks and firecrackers from the sources and sources of raw material sources and product sales. .
It is found that illegal fireworks and firecrackers containing potassium chlorate and the illegal production of fireworks and firecrackers using potassium chlorate should trace the source of illegal fireworks and firecrackers and potassium chlorate. If the illegal products and potassium chlorate source are across provinces (autonomous regions and municipalities), the provincial-level safety supervision bureau shall promptly notify the provincial safety supervision bureau of the source of the investigation. The investigation unit should carefully organize the verification and timely feedback.
The notice stressed that the daily inspections at all levels of the safety supervision department found that illegal fireworks and firecracker products and pharmaceuticals containing potassium chlorate should be immediately sealed on the spot and sent to the inspection and testing institutions with relevant qualifications for re-inspection and confirmation, and the relevant information will be reported to the province. Level safety supervision bureau.
The State Administration of Work Safety also recommended that it has passed technical appraisal by the scientific and technological departments, such as “aromatic environmental safety type†and “Hua’an No.1â€, as a potassium chlorate replacement drug for fireworks and firecrackers.
