Lower limits of concentration
6.—(1) For preparations to which this Schedule applies, account shall be taken of dangerous substances which are classified as dangerous on the basis of their health or environmental effects (whether they are present as additives or impurities) when their concentrations are equal to or greater than those defined in the following table unless lower limits are given in the approved supply list or in Part II of this Schedule—
| Category of danger of the substance | Concentration to take into consideration for | |
|---|---|---|
| gaseous preparations % vol/vol | other preparations % w/w | |
| Very toxic | ≥0.02 | ≥0.1 |
| Toxic | ≥0.02 | ≥0.1 |
| Carcinogenic Category 1 or 2 | ≥0.02 | ≥0.1 |
| Mutagenic Category 1 or 2 | ≥0.02 | ≥0.1 |
| Toxic for reproduction Category 1 or 2 | ≥0.02 | ≥0.1 |
| Harmful | ≥0.2 | ≥1 |
| Corrosive | ≥0.02 | ≥1 |
| Irritant | ≥0.2 | ≥1 |
| Sensitising | ≥0.2 | ≥1 |
| Carcinogenic Category 3 | ≥0.2 | ≥1 |
| Mutagenic Category 3 | ≥0.2 | ≥1 |
| Toxic for reproduction Category 3 | ≥0.2 | ≥1 |
| Dangerous for the environment N | ≥0.1 | |
| Dangerous for the environment ozone | ≥0.1 | ≥0.1 |
| Dangerous for the environment | ≥1 | |
(2) Some substances may have more than one health effect and each of these properties shall be characterised by its specific concentration limit.
