Gaseous preparations
2.2 For gases that produce non-lethal irreversible effects after a single exposure (R39/route of exposure, R68/route of exposure), the individual concentration limits specified in Table IIA, expressed as a volume/volume percentage, determine, when appropriate, the classification of the preparation.
Table IIA
| Classification of the substance (gas) | Classification of the preparation | ||
|---|---|---|---|
| T+ | T | Xn | |
(*) In order to indicate the route of administration/exposure the combined R phrases listed in Annex III of Council Directive 67/548/EEC shall be used. | |||
(†) R68 here refers to substances classified as harmful. Concentration limits for substances required to be labelled R68 but classified mutagenic are given in Table VI. | |||
| T+ with R39/ route of exposure | concentration ≥ 1% R39(*) obligatory | 0.2% ≤ concentration < 1% R39(*) obligatory | 0.02% ≤ concentration < 0.2% R68(*)(†) obligatory |
| T with R39/ route of exposure | concentration ≥ 5% R39(*) obligatory | 0.5% ≤ concentration < 5% R68(*)(†) obligatory | |
| Xn with R68/ route of exposure | concentration ≥ 5% R68 (*)(†) obligatory | ||
