Eight Immortals Paradise (picture taken from official website Eight Immortals Paradise) Once any substance is presented in the form of dust, it will accelerate oxidation.
Professor Wu Jiacheng said that compared with substances with the same mass and volume, once any substance is presented in the form of dust, its surface area will increase by at least 10,000 times, and its particles will become smaller, so the chances of contact with air will come from all directions, which will naturally accelerate oxidation. Take charcoal burning as an example, it is not easy to burn, but it is easy to burn when it is turned into tiny sawdust.
It is particularly dangerous that the dust itself becomes hot easily. In the case of colored dust, flammable metals should be added to change such colorful colors. In the past, many factories died because of metal dust explosion.
Even without actual contact with the fire source, colored dust will explode and burn under the thermal catalysis of light intensity.
Once the amount of colored dust in a local space increases, even if there is no actual contact with the fire source, such as cigarette butts, or sparks caused by short circuit of wires, the dust may explode and burn under the thermal catalysis of the intensity of the stage lights. Moreover, the speed of dust expansion is very fast, which can be described as supersonic speed. Haven't heard the sound, the fire has burned people. No wonder the destructive power is so strong.
In recent years, it is crazy to run on colorful roads in China, and colorful corn flour can be sprinkled at parties to add fun. Professor Wu Jiacheng said that this is a very dangerous activity and the public should have a sense of crisis. There is also a reminder that inhaling colored dust containing metal components and carcinogenic azo dyes is also harmful to the respiratory tract. Call for strict control of such dangerous activities in China to avoid accidental casualties.
Party toner is the first disaster. Premier: Don't use colored powder any more.
Premier Mao Zhiguo said this morning that the Executive Yuan has asked the Fire Department of the Ministry of the Interior to stop using colored powder in public activities before the safety of colored powder is further determined, and the Fire Department will also convene experts from relevant units to discuss and formulate necessary management measures as soon as possible. Minister Jiang said that this was the first time that such an accident occurred in an open-air place in China, and metal colored powder used to strengthen the management of entertainment purposes would be studied.
According to the press release issued by the New Taipei Municipal Government at 1 1 33 pm on the 28th, the number of injured people remitted by the "Emergency Registration System of the Ministry of Health" is 498 at present after deducting the repeated count of patients transferred due to illness. This statistic will be confirmed tomorrow after sorting out the data of the injured who have been transferred to other counties and cities.
For patients with extensive burns and scalds, the primary task of treatment within 72 hours is to stabilize the vital signs of the injured. Only after the vital signs of the patients are stable can the burns and scalds be treated. Some burn patients need skin transplantation, and the Ministry of Health and Welfare sends enterprise organ donation center, plastic surgery medical association and burn medical association to assist in "sending skin from the south to the north", so that hospitals can adopt artificial skin or donate skin according to the patient's condition.
