4 Chemical substances in experimental sets
See B.1.
4.1 Chemistry sets
Only the chemical substances, mixtures and indicators given in Table 1 and Table 2 may be supplied in chemistry sets or in a supplementary set for a chemistry set up to the amounts and concentrations specified in those tables.
The quality of the chemicals used should be appropriate for the experiments described. In particular, the chemicals should not contain impurities or substances that allow undefined or dangerous reactions to occur.
Apart from its presence in tincture of iodine, denatured alcohol (ethanol) shall not be supplied in a chemistry set. However, where experiments contained in the instructions of a chemistry set require it, the use of denatured alcohol may be suggested in the instructions.
The use of reagents listed in Table 3 may be suggested in the instructions at concentrations not exceeding those specified in this table. The substances specified in Table 3 shall not be supplied in a chemistry set.
The instructions for use may suggest the use of other substances that are not classified as dangerous substancesLil (e.g. sucrose or table sugar) or mixtures that are not classified as dangerous mixtures[1i. Other dangerous substances shall not be supplied with the set.
The substances and mixtures in a chemistry set or in a supplementary set of a chemistry set shall be supplied in containers which are provided with closures (see 5.2.4.1).
NOTE 1 Samples of rocks, stones and minerals on which to perform experiments in order to distinguish their composition are sometimes supplied with the set.
Colourants and colouring materials which are not specified in Table 2 may only be supplied in chemistry sets if they do not react with the substances and mixtures of the set and if they do not fulfil the criteria of any of the following hazard classes:
— “acute toxicity” (hazard class 3.1),
— “skin corrosion/irritation” (hazard class 3.2),
— “serious eye damage/eye irritation” (hazard class 3.3),
— “respiratory or skin sensitisation” (hazard class 3.4),
— “germ cell mutagenicity” (hazard class 3.5),
— “carcinogenicity” (hazard class 3.6),
— “reproductive toxicity” (hazard class 3.7),
— “specific target organ toxicity — single exposure” (hazard class 3.8),
— “specific target organ toxicity — repeated exposure” (hazard class 3.9),
— “aspiration hazard” (hazard class 3.10).
Colourants which are permitted for use in food or cosmetics may be provided.
NOTE 2 The classification is detailed in the GHS (Part 3: Health Hazards).AS/NZS 8124.4 pdf download.
