The current situation of dangerous goods packaging industry in Britain (1)

in early March 2003, Guangzhou held a publicity and implementation meeting for the renewal of production license of dangerous chemicals packaging containers, which further emphasized the importance of normative documents such as the implementation rules for production license of dangerous chemicals packaging and container products, on-site assessment methods, product inspection rules, etc

it is reported that in order to strengthen the management of the production of packages and containers of hazardous chemicals, ensure the quality of packages and containers of hazardous chemicals, and ensure the safety of storage, handling, transportation and use of hazardous chemicals, the measures for the administration of the designated production of packages and containers of hazardous chemicals has been implemented since November 15, 2002, while the detailed rules for the implementation of the production license of packages and containers of hazardous chemicals, It has also been implemented since January 6th, 2003. All these show that the relevant departments of our country attach great importance to the safety management of hazardous chemicals. For this reason, this issue excerpts Rodney Abbott's views on dangerous goods packaging in the UK, so that the industry can have more understanding of foreign dangerous goods packaging

the dangerous goods packaging industry in Britain is on the decline. Today, the cost of molding, loading in continental Europe, and then shipping the packaging back to the UK will be lower. The following three tragic accidents raise a question: whether the packaging of dangerous goods needs to comply with very strict industry norms. However, whether there are regulations or not, the industry still treats the packaging of dangerous goods wrongly

In 1973, a Pan Am 707 cargo plane crashed in Boston due to nitric acid leakage

In 1989, a car loaded with explosives exploded in Peterborough, killing one person and almost destroying the entire industrial area

in May 1999, a British company was fined 95000 pounds because they did not declare the cost of transporting the 24000 pound oxygen concentrator, and the packaging was incorrect

in fact, as far as packaging is concerned, the United Nations, like many other trustworthy institutions, has done a very good job. Although the United Nations is sometimes criticized, its contribution to updating the orange book is obvious to all

the design of drums, cans and intermediate bulk containers (IBC containers) is based on their practical applications and is determined by the famous orange book of the United Nations. This book introduces in detail how to classify, package, mark, label and prepare supporting documents for dangerous goods

in this book, dangerous goods are divided into nine categories. The original intention of the authors is probably to show the danger of dangerous goods from strong to weak through the sequence of classification numbers. However, today, no matter what standard is used, some substances and goods in level 9 are more dangerous than some goods in level 1

therefore, classified numbers can only be regarded as a means of identification

the United Nations divides dangerous goods into three groups. The first group is high-risk substances. The second group is a series of acids and bases, but the concentration is not very high. The third group is the least dangerous substance. These three groups of substances are also divided into solid and liquid. This makes the problem quite complicated

if you are not familiar with international standards, you can find simple guidelines from Pira International - transportation of dangerous goods (Fifth Edition, written by Martin Castle)

dangerous substances and goods are packed in a series of flexible and hard containers, which will greatly improve the working efficiency, because in this field, if there is no appropriate processor, it is only used to store substances, and it does not need an attractive or innovative appearance as necessary in other areas of the packaging industry

however, when the design of packaging is stipulated by the association, the importance of innovation is really minimized, so the industry can't help asking: how can technology find sufficient breathing space in the world to develop safely

it is difficult to innovate in this field. Therefore, once a series of drums or (IBC) containers have been certified, this rule - since it is effective, why should it be modified - may continue

demand is still the key driving force for innovation. To find the freshness of dangerous goods packaging, you can see the agrichem 5-liter and 10 liter containers of Nampak company, which are suitable for transportation and packing of the same size

the sizes of these two containers meet the 63mm bottleneck size and wide handle design of the industry standard, which is to ensure the safety of the application process and the spraying of chemical pesticides. Both containers are placed in the same outer transport carton, and the packing mode is 5 liters × 4 or 10 liters × 2。 The 5-liter and 10 liter containers have obtained the compound certificate of the United Nations, which can be used to store the chemical substances classified as UN group II, 1.4sg. The 5-liter agricultural chemical containers also have two materials: single-layer high-density polyethylene and joint stamping hdpe/pa, both of which can store the chemical substances of aqueous solvents and organic solvents. In this way, all products with the same compound certificate number can be transported in one UN compound outer transport box, thereby reducing the number of transport boxes required by packers

in addition, 5-liter and 10 liter containers have obtained the free standing certificate of the United Nations - UN group II, 1.4sg, which has covered the transportation link from the seller to the end user, as well as the possible collapse of the compound packaging approved by the United Nations. Also relatively new products are surftec system launched by harcostar company. Harcostar began to study different products for customers who need lighter and environmentally friendly transportation products when transporting these dangerous chemicals. In the past five years, they have studied the existing plastic treatment methods to prevent dust from falling into the machine, and invested more than 1million pounds to develop the inner wall coating of plastic drums. This research is very difficult, because the solvent that can make the container impermeable usually has a low ignition point - which can cause very serious safety problems

harcostar has developed a double coating that can meet these two requirements. The specific effect depends on the specific requirements. As a result, the patent right of surftech has not been determined, and all harcostar drums treated with this coating have been recognized by the United Nations and can be used to store many kinds of dangerous goods. Surftech is the result of harcostar's research on a new method - more importantly, this coating applied to the inner wall of plastic drums has become a barrier to prevent the penetration of chemicals. Surftech can be applied to the finished inner wall of 45 gallon plastic drums, and the treated drums can store hydrocarbon solvents, which has been recognized by the United Nations

Of course, plastics can be shaped into various shapes to meet specific needs and facilitate loading and transportation. Therefore, plastic products greatly reduce the cost of storage, processing and delivery, and also improve the payload of land transportation and ISO shipping container transportation

many industries have begun to accept the concept of "reuse", and in this regard, plastic drums are the same. Its durability and robustness make it recyclable in catering, chemical, photography, water treatment, crop protection and other industries

plastic drums can also be washed with traditional reshaping equipment. Repeated use of drums will inevitably reduce the production of packaging waste

the industry has three requirements for products - operator protection, environmental protection and solvent treatment
