PART B CATEGORIES OF SUBSTANCES AND PREPARATIONS NOT SPECIFICALLY NAMED IN PART A

Column 1	Column 2
Categories of hazardous substances		Controlled Quantity (Q) in tonnes
NOTES TO PART B 1. Substances and preparations must be classified for the purposes of this Schedule according to regulation 4 of the Chemicals (Hazard Information and Packaging for Supply) Regulations 2009(11) (CHIP) whether or not the substance or preparation is required to be classified for the purposes of those Regulations or, in the case of a pesticide approved under the Food and Environment Protection Act 1985(12), in accordance with the classification assigned to it by that approval. 2. An “explosive” means: a substance or preparation which creates the risk of an explosion by shock, friction, fire or other sources of ignition (risk phrase R2), a substance or preparation which creates extreme risks of explosion by shock, friction, fire or other sources of ignition (risk phrase R3), or a substance, preparation or article covered by Class 1 of the European Agreement concerning the International Carriage of Dangerous Goods by Road (UN/ADR), concluded on 30 September 1957, as amended, as transposed by Council Directive 94/55/EC of 21 November 1994 on the approximation of the laws of the Member States with regard to the transport of dangerous goods by road (13). Included in this definition are pyrotechnics, which for the purposes of these Regulations are defined as substances (or mixtures of substances) designated to produce heat, light, sound, gas or smoke or a combination of such effects through self-sustained exothermic chemical reactions. Where a substance or preparation is classified by both UN/ADR and risk phrase R2 or R3, the UN/ADR classification must take precedence over assignment of risk phrases. Substances and articles of Class 1 are classified in any of the divisions 1.1 to 1.6 in accordance with the UN/ADR classification scheme. The divisions concerned are: Division 1.1: Substances and articles which have a mass explosion hazard (a mass explosion is an explosion which affects almost the entire load virtually instantaneously). Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard. Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard: (a) combustion of which gives rise to considerable radiant heat; or (b) which burn one after another, producing minor blast or projection effects or both. Division 1.4: Substances and articles which present only a slight risk in the event of ignition or initiation during carriage. The effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire will not cause virtually instantaneous explosion of virtually the entire contents of the package. Division 1.5: Very insensitive substances having a mass explosion hazard which are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions of carriage. As a minimum requirement they will not explode in the external fire test. Division 1.6: Extremely insensitive articles which do not have a mass explosion hazard. The articles contain only extremely insensitive detonating substances and demonstrate a negligible probability of accidental initiation or propagation. The risk is limited to the explosion of a single article. Included in this definition are also explosive or pyrotechnic substances or preparations contained in articles. In the case of articles containing explosive or pyrotechnic substances or preparations, if the quantity of the substance or preparation contained is known, that quantity must be considered for the purposes of these Regulations. If the quantity is not known, then, for the purposes of these Regulations, the whole article must be treated as explosive. 3. In categories 6, 7, 8 and 9, “flammable”, “highly flammable”, and “extremely flammable” mean— (a) flammable liquids means substances and preparations having a flash point equal to or greater than 21 °C and less than or equal to 55°C (risk phrase R 10), supporting combustion; (b) highly flammable liquids means— (i) substances and preparations which may become hot and finally catch fire in contact with air at ambient temperature without any input of energy (risk phrase R 17); (ii) substances and preparations which have a flash point lower than 55°C and which remain liquid under pressure, where particular processing conditions, such as high pressure or high temperature, may create major-accident hazards; and (iii) substances and preparations having a flash point lower than 21 °C and which are not extremely flammable (risk phrase R 11, second indent); (c) extremely flammable gases and liquids means— (i) liquid substances and preparations which have a flash point lower than 0 °C and the boiling point (or, in the case of a boiling range, the initial boiling point) of which at normal pressure is less than or equal to 35 °C (risk phrase R 12, first indent), (ii) gases which are flammable in contact with air at ambient temperature and pressure (risk phrase R12, second indent), which are in a gaseous or supercritical state, and (iii) flammable and highly flammable liquid substances and preparations maintained at a temperature above their boiling point.
NOTES TO PARTS A AND B 1. Mixtures and preparations must be treated in the same way as pure substances provided they remain within the concentration limits set according to their properties under the relevant provisions specified in CHIP, unless a percentage composition or other description is specifically given. 2. In the case of substances and preparations with properties giving rise to more than one classification the lowest thresholds must apply. 3. Where a substance or group of substances listed in Part A also falls within a category of Part B, the controlled quantities set out in Part A must be used. 4. In the case of an establishment where no individual substance or preparation is present in a quantity above or equal to the relevant controlled quantity for that substance or preparation, the addition of hazardous substances to determine the controlled quantity must be carried out according to the following rule: If the sum— (where qx = the quantity of hazardous substance x (or category of substance) present, Q = the relevant controlled quantity (Q) from Part A or Part B, except for those substances for which column 3 of Part A contains a quantity Q*, in which case the quantity Q* must be used in place of the controlled quantity Q in column 2) then the controlled quantity of each of the substances which are added together in accordance with each of paragraphs 5(a) to (c) below must be deemed to be present for the purposes of sections 4(2), 14(2)(c), 23(2)(a) and of section 181 (enforcement notice to have effect against subsequent development) of the Town and Country Planning Act 1990(14) as substituted by paragraph 8 of Schedule 4. 5. The addition rule in paragraph 4 will apply for the following circumstances:— (a) for the addition of substances and preparations named in Part A and classified as toxic or very toxic, together with substances and preparations falling into categories 1 or 2 of Part B; (b) for the addition of substances and preparations named in Part A and classified as oxidising, explosive, flammable, highly flammable, or extremely flammable, together with substances and preparations falling into categories 3, 4, 5, 6, 7, 8 or 9 of Part B; (c) for the addition of substances and preparations named in Part A and classified as dangerous for the environment (R50 (including R50/53) or R51/53), together with substances and preparations falling into categories 10(i) or 10(ii) of Part B.

Hazardous substances	Controlled quantity
NOTES TO PART C 1. The expression “which it is believed may be generated during loss of control of an industrial chemical process” has the same meaning as in the Directive. 2. Where a substance falling within Part A or B also falls within Part C, the classification with the lowest controlled quantity must apply, subject to note 3 to the notes to Parts A and B.”
