4 CLAssiFiCAtion
Hazard classification is the assignment of a standardised description of the hazard of a substance or a mixture causing harm due to (a) its physical properties, (b) its effects on human health or (c) the environment.
Each of these properties has a number of classes and these classes are categorised; category 1 being a more serious hazard than category 4.
There are 17 classes of physical hazard, 10 classes of health hazard and 2 classes of environmental hazard. Every hazard has a definition. For example, under CLP the definition of a flammable liquid is a “liquid having a flash point of not more than 60° C”.Therefore liquids with a flashpoint greater than 60° C are not flammable liquids.They may have other physical properties that fall under one, or more than one, of the physical hazards. Under CLP, flammable liquids have 3 categories (see below).
The role of the EU manufacturer or importer is to classify the substance or mixture to determine if it falls within the
4.1 Classes and categories
4.1.1 Physical hazards
1. Explosives (Unstable explosives, Divisions 1.1, 1.2, 1.3, 1.4, 1.5, and 1.6)
2. Flammable gases (Categories 1A (including unstable gases (Categories A and B) and pyrophoric gases) 1B and 2
3. Aerosols (Categories 1, 2 and 3)
4. Oxidising gases (Category 1)
5. Gases under pressure (Compressed gas, liquefied gas, refrigerated liquefied gas, dissolved gas)
6. Flammable liquids (Categories 1, 2 and 3)
7. Flammable solids (Categories 1 and 2)
8. Self-reactive substances and mixtures (Types A, B, C, D, E, F, & G)
categories defined as Hazardous. A substance that is classified as Hazardous then has to be labelled correctly with applicable hazard statements, pictograms, and signal word, and the applicable statements that advise how to handle the substance or mixture (the precautionary statements).
In the case of essential oils and vegetable oils that are exported from South Africa, the EU importer would have to gather the appropriate information to make the classification.The EU importer may request that information from the South African exporter. For example, the classi- fication and labelling information will be included in Section 2 of the safety data sheet (SDS) prepared by the South African exporter. See examples of classification and labelling, and Annex 1 below.
9. Pyrophoric liquids (Category 1)
10. Pyrophoric solids (Category 1)
11. Self-heating substances and mixtures (Categories 1 and 2)
12. Substances and mixtures which in contact with water emit flammable gases (Categories 1, 2 and 3)
13. Oxidising liquids (Categories 1, 2 and 3)
14. Oxidising solids (Categories 1, 2 and 3)
15. Organic peroxides (Types A, B, C, D, E, F & G) 16. Corrosive to metals (Category 1)
17. Desensitised explosives
