See also: List of all items in class 5 Class 6 Toxic and infectious substances Class 6 consists of the following classes ClassĬlass 6.1, toxic substances, is used to classify substances that - in relatively small amounts and in a short duration - can cause serious injury or death to humans if swallowed, inhaled or with by absorption through skin contact.Ĭlass 6.2, infectious substances, covers substances which are known or are reasonably expected to contain pathogens, i.e. They can be very unstable and extremely flammable under certain circumstances such as heat, friction, mechanical shock, or when they come into contact with other substances. This can cause a fire to accelerate quickly, or to start due to the heat given off in the oxidation process.Ĭlass 5.2, organic peroxides, may also decompose at a high rate and give off oxygen or flammable gases, as well as heat. See also: List of all items in class 4 Class 5 Oxidizing substances and organic peroxides Class 5 consists of the following classes ClassĬlass 5.1, oxidizing substances, are substances that may decompose quickly, releasing oxygen or other oxidizing substances. For instance, strike-anywhere-matches (UN 1331) would be classified as a Class 4.1 substance. They all have in common that they are flammable under certain conditions.
Substances which, in contact with water, emit flammable gases Substances liable to spontaneous combustion See also: List of all items in class 3 Class 4 Flammable solidsĬlass 4, like class 5 and 6, is actually an umbrella term, where all substances belong to one of the subclasses.Ĭlass 4 consists of the following subclasses Classįlammable solids, self-reactive substances, polymerizing substances and solid desensitized explosives Substances are divided into different packing groups according to the degree of danger they present to transportation. See also: List of all items in class 2 Class 3 Flammable liquidsĬlass 3 covers flammable liquids, which includes some molten solid substances and liquid desensitized explosives.
In some regulations, gases in class 2 are divided into divisions 2.1 - 2.3 depending on their primary hazard. Gases in class 2 are assigned one or more groups, representing their dangerous properties. See also: List of all items in class 1 Class 2 GasesĬlass 2 contains potentially dangerous gases. The compatibility group letter indicates which items can be transported together. A compatibility group, consisting of a single letter, is also assigned to each item. Items in Class 1 are further divided into divisions 1.1 - 1.6 depending on the nature of the explosion hazard and the sensitivity of the item. The classes are part of the United Nations-based system of identifying dangerous goods, and are used within many different subsystems such as the ADR, RID, IMDG and DGR for classifying dangerous goods and hazardous materials.Ĭlass 1 Explosive substances and articlesĬlass 1 contains substances and articles which pose a hazard due to explosion. If the goods have multiple dangerous propreties, the most dominant one determines the class to which it shall belong. Class 9 - Miscellaneous dangerous substances and articlesĭangerous goods are classified into 9 different classes, based on the dangerous properies of the goods or substance.Class 6 - Toxic and infectious substances.
Class 5 - Oxidizing substances and organic peroxides.Class 1 - Explosive substances and articles.
