Where a substance has been classified from "first principles", its PG will be determined by its properties (for example ADR 2.2.3.1.3 shows how flammable liquids are assigned a PG)ġ0 Some substances are not assigned a PG (notably gases and explosives), but they do have a transport category, the relevance of which will be discussed elsewhere ( Main Exemptions) in relation to limited load exemptions. The head of column 4 in turn directs you to the relevant part of ADR (in this case 2.1.1.3). This is reflected in the "packing group" (PG), which is found in column 4 of table A. Some substances with the same name will have different degrees of danger (for example flash point). There are some specific exceptions which are set out in 2.1.3.3ĩ Once a UN number and proper shipping name have been assigned, table A allows all the relevant parts of ADR to be accessed. The effect of this is that dangerous goods should be classified and named according to the properties of the predominant substance, and in general the presence of impurities is not relevant. In those cases the rules for classification need to be followed.ĨĚn important change was made in ADR 2011 in paragraph 2.1.3.3. Both lists are at the end of Volume 1 of ADR.ħ Many preparations (ie mixtures of substances) will not be found in table A of ADR. The lists are by UN Number (Table A) and alphabetical (Table B). There is a hierarchy of classification (ADR 2.1.3.5.3) and there are rules about choosing the most appropriate entry and hence UN number (ADR 3.1.2).Ħ Many substances and generic groups (eg paints) have already been classified, so in many cases a consignor may only need to find his substance in the "dangerous goods list", which is in part 3 of ADR. The consignor must assign a "proper shipping name" and UN Number to the substance.ĥĚll relevant hazards have to be determined (ADR 2.1.2.1). It sets out descriptions and criteria in some detail. Substance which in contact with water emits flammable gasĤ Part 2 of ADR works through the categories in logical sequence. There are nine classes, some with divisions, as follows. Dangerous substances (and this includes articles) are very widely defined, but some, for example most medicines and cosmetics, do not have the hazardous properties that would bring them within scope of the requirements, and those that do are usually carried in very small receptacles, allowing at least partial exemption from the requirements (either limited quantities or limited loads - see Main Exemptions)ģ Consignors have a duty to identify the hazards of the goods they intend to transport. ADRĢ The rules for classification are in ADR at part 2. Once a substance or article has been properly classified, table A (ADR 3.2.1) allows every other requirement to be ascertained by working logically through the columns. Consignment procedures (including documentation)ġ ADR works in such a way that classification is the precursor for everything that follows.ADR, CDG Regulations and Dangerous Goods Safety Advisers. ![]()
