On the packaging of dangerous goods by air

Talking about the packaging of dangerous goods by air (I)

with the rapid development of the national economy, the aviation industry is advancing by leaps and bounds, especially in recent years, the number of dangerous goods by air has increased sharply, which has attracted enough attention from the relevant departments. Many people, including production enterprises, carriers and inspectors, still have many misunderstandings in their understanding, and many packages fail to meet the requirements of the "technical rules for the safe transportation of dangerous goods by air", Some people even confuse the packaging requirements of dangerous goods by sea and dangerous goods by air. It is precisely because of the confusion of the concept, the delay of shipment, and the loss, which is fully due to the lack of understanding of the particularity of "air transportation", so the loss is inevitable. Here are three examples. I hope readers will have an insight after understanding these examples, so as to avoid repeating the mistakes

in 2000, the comrade in charge of packaging of the entry exit inspection and Quarantine Bureau received the factory's declaration that a batch of fireworks and firecrackers were to be exported to South America by air. He hoped that the Bureau would send personnel to inspect them. Because the bureau had not been engaged in the inspection of dangerous goods by air before, it carried out according to the usual practice of inspection of dangerous goods by sea. After passing the inspection, a certificate of identification for the use of dangerous goods by sea was issued, An official of the Ministry of foreign affairs was responsible for the shipment of this batch of dangerous goods. It turned out that this was foreign aid. A country in South America is a small country that has so-called "diplomatic relations" with Taiwan. After the work of the Ministry of foreign affairs, it agreed to break diplomatic relations with Taiwan and intend to establish diplomatic relations with the people's Republic of China. However, a prerequisite was that the Ministry of foreign affairs was required to provide a batch of fireworks and firecrackers with a price of up to US $1 million free of charge, because Taiwan had previously provided fireworks and firecrackers during the national day of the country, Now that Taiwan has interrupted its "diplomatic relations" with Taiwan, Taiwan will certainly not provide any more. According to statistics, the Ministry of foreign affairs has promised to implement the task of making high-grade fireworks and firecrackers in a factory in Jiangsu Province. It is obviously too late to ship the fireworks and firecrackers, so it proposed air transportation, so the factory applied for dangerous goods inspection, and issued a letter of signature applicable to sea transportation without consent, saying that it is an alternative air transportation certificate, The staff of the Ministry of foreign affairs took this certificate to China Eastern Airlines, but of course, China Eastern Airlines rejected it and asked for a certificate of use suitable for air transportation. The inspectors of a bureau took back the identification certificate used by sea and replaced it with an identification certificate used by air transportation. The personnel of the Ministry of foreign affairs went to China Eastern Airlines again. The staff of China Eastern Airlines found that this batch of high-grade fireworks and firecrackers obviously belonged to the first category of dangerous goods - prohibited substances in explosives, so they refused to carry them. The Ministry of foreign affairs was forced by diplomatic needs to issue a letter of guarantee for shipment, and China Eastern Airlines had no choice but to agree. However, there are no direct flights between South America and China, and the aircraft to be transshipped in South Africa is German Airlines. China Eastern Airlines contacted German Airlines, which was rejected by German Airlines, because this practice clearly violates the "technical rules for the safe transport of dangerous goods by air" formulated by the international civil Aviation Organization The Ministry of foreign affairs proposed to charter a huge amount of money, but the pilot of German Airlines refused to drive, and the stewardess refused to go to work. In this case, they had to give up, causing losses on the diplomatic front. Of course, the staff engaged in inspection was seriously dealt with

more than 300 representatives from enterprises, scientific research institutions and universities gathered in Luoyang to discuss the development of the industry. From this serious political event, there are significant differences in packaging requirements and transportation regulations between ocean shipping and aerospace, which must not be equated

a drug leak occurred on the flight from Shanghai to Hong Kong in 2004. Several people were poisoned and sent to hospital for treatment. We can integrate the online and offline advantages of both sides. When investigating the cause of the accident, we learned that the steel barrel cover was not tightened, resulting in the leakage of toxic substances

the first thing to do for transporting dangerous liquid goods by air is to tighten the sealer. The required rotating torque is greater than that of shipping, so the requirements for the manufacture and material of the sealer are higher, and the phenomenon of tooth slippage cannot be caused by increasing the torque. In addition, the capacity of filling liquid dangerous goods shall not exceed 98%, but not less than 65%. This requirement does not exist in the maritime regulations, because the aircraft will often dive and rise straight due to the air flow during shipping. If the contents of the container are small, the space in the container is too large, and the aircraft is moving up and down violently, the liquid will have a great impact on the container, resulting in leakage, If the sealer is not tightened, it is likely to flush the sealer away, causing leakage

the damage site can be found quickly and effectively through ultrasound and thermal imaging technology
