A : The packaging used to contain dangerous goods must be good quality and completely sealed to prevent the leakage of dangerous goods during transportation, which may cause vibration, temperature change, humidity or pressure. The form of the packaging is in accordance with the nature and status of the hazardous substance being packaged, which can be divided into 3 types:     Characteristics of package type is a product that is completely packaged. The goods contained within are ready to be delivered. Can act to completely conceal the contents and includes gas containers and items of any mass or nature that can be transported without packaging or transported by placing it on a litter in crates or in other handling equipment. The transport of radioactive materials, dangerous goods transported in bulk or in tanks are not included. Dangerous goods are classified into packing groups based on the hazard level of the substance as follows: Packing group I: Substances with a high degree of hazard. Packing group II : Substances of medium hazard class. Packing group III: Substances of low hazard class. The letters representing the packing group are: X for packing group I, II and III Y for packing group II and III Z only for packing group III   Characteristics of packaging type is one or several containers, including components or materials necessary for the purpose of containment of hazardous substances and perform safety functions. IBC (Intermediate Bulk Container) packaging is the packaging that moveable, stable or flexible. Capacity depends on packing group and hazardous material status. Designed to be transported by machines. Tested to withstand the stresses caused by handling and transport in accordance with standards related to the transport of dangerous goods by road with the following features: Capacity not more than 3.0 cubic meters (3,000 liters) for solids and liquids of packing group II and III. Capacity not to exceed 1.5 cubic meters for solids of packing group I when packed in IBC made of plastics, composites, fibreboard and wood. Capacity not more than 3.0 cubic meters for solids in packing group I when packed in metallic IBC. Capacity not more than 3.0 cubic meters for radioactive material type 7 Large packaging is a packaging that contains outer packaging, which contains items or packages contained within. Designed to be lifted or moved by machine and having a net weight of more than 400 kilograms or having a capacity of more than 450 liters but with a volume not exceeding 3 cubic meters.   Characteristics of the tank type is a hazardous substance container that is equipped with structural equipment and related equipment. Tank Container is a walled tank with structural equipment and related equipment such as equipment used for lifting or moving for gas, hazardous, liquids transportation and materials in the form of powder or granules and has a capacity of more than 450 liters. Portable tank is a liftable and movable tank used for multimodal transport with a capacity of more than 450 liters, which includes all necessary equipment for transport.   Conditions of information that must be posted on dangerous goods packaging. On dangerous goods packaging it is necessary to display the UN number, chemical name, primary risk label, subsidiary risk label and a certified UN mark.
