Caution — substance not yet fully teste

A list of danger categories is given in Table 14.2. Note that chemicals may possess several hazards, e.g. nitric acid is classed as both an oxidizer and a conosive. If a chemical is not in one of these categories it is not generally considered to be dangerous. If the hazards of a new chemical have not been established it should be labelled Caution - substance not yet fully tested . Mixtures can be classified either from results from tests on the preparation, or by calculation to predict the healtli effects of the product based on the properties of individual components and tlieu concentration in the mixture. Preparations need to be classified for both physico-chemical and health effects but, to date, not for environmental effects. 

Requirements for labelling of containers for supply may differ from those for conveyance. Key features of a supply label are to identify the substance (the chemical name in most cases) and any hazards and safety precuations. In Europe the classification, packaging and labelling of dangerous substances is covered by Directive 67/548/EEC as amended. This requires labels to identify appropriate risk and safety phrases (Tables 12.2 and 12.3) depending upon product properties. A substance is considered dangerous if in Part lA of an approved list or if it exhibits hazardous properties as defined in Schedule 1 for supply, or Schedule 2 for conveyance as shown in Tables 12.4 and 12.5. Substances not tested should be labelled Caution — substance not yet fully tested . Criteria for risk phrases are provided, e.g. as in Table 12.6 for toxic compounds. 

Examples of Level 1 tests which may be required at 10 tonnes per year (or 50 tonnes total) and will be required at 100 tonnes per year (or 500 tonnes total) are given in Table 12.11. Level 2 studies which will be required at 1000 tonnes per year (or 5000 tonnes total), unless the supplier can justify their exclusion to the Competent Authorities, are listed in Table 12.10. Until safe data are available the substance should be labelled Caution — substance not yet fully tested . 

A Limited Announcement can be made for a new substance supplied at <1 tonne a, or to a restricted number of specified users for commercial development at above this amount for 1 year only. L.ess information is required for Limited Announcement for supply at <10 kg a, and even less for <1 kg a. Comparatively few new substances reach the 1 tonne a supply level, so most are authorised under the Limited Announcement scheme, although sometimes the full EC Base Set data are available to enable definitive and complete hazard classification and labelling and avoid having to label the substance as Caution Substance not yet fully tested . 

The substance has to be labeled Caution - substance not yet fully tested .
