Definition and further description of Annex III to WFD
Annex III to the WFD defines HP 2 ‘Oxidising’ as: ‘waste which may, generally by providing oxygen, cause or contribute to the combustion of other materials’ The WFD further explains that: ‘When a waste contains one or more substances classified by one of the hazard class and category codes and hazard statement codes shown in Table 2 [see Table 9 of this document], the waste shall be assessed for HP 2, where appropriate and proportionate, according to test methods. If the presence of a substance indicates that the waste is oxidising, it shall be classified as hazardous by HP 2.’ A waste containing substances that are classified with the hazard class, category and statement codes in Table 9 can be tested to show whether it displays that hazardous property or not. Alternatively a waste containing those substances can simply be assumed to be hazardous by HP 2. Hazard Class and Category Code(s) Hazard statement Code(s) Description Ox. Gas 1 H270 May cause or intensify fire; oxidiser Ox. Liq. 1 H271 May cause fire or explosion; strong oxidiser Ox. Sol. 1 Ox. Liq. 2 Ox. Liq. 3 H272 May intensify fire; oxidiser Ox. Sol. 2 Ox. Sol. 3 Where — the waste contains only one of these substances; — that substance is assigned a specific concentration limit in Table 3 of Part 3 of Annex VI to CLP. It should be noted that there are no generic concentration limits applicable to this hazard class; — that substance is present in the waste below that limit; it can be assumed that the waste is not hazardous by HP 2. An example is ‘nitric acid’ which is listed as H272, Ox. Liq. 3 with a specific concentration limit of ≥ 65 %. Where ‘nitric acid’ is present in a waste above 65 % that waste has to be classified as HP 2 (in addition to HP 8). The only other substance which, up to ATP 10 of CLP (2) has an SCL for oxidising properties is hydrogen peroxide, with a limit of 50 %.
