Paragraph 2.2 Gaseous preparations
For gases that produce non-lethal irreversible effects after a single exposure (R39/route of exposure, R40/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 paragraphs 44, 45 and 46 of the approved classification and labelling guide shall be used. | |||
(†) R40 here refers to substances classified as harmful. Concentration limits for substances required to be labelled R40 but classified as carcinogenic or mutagenic are given in Table VI. | |||
| T+ with R39/route of exposure | concentration > 1% R39f1 obligatory | 0.2% < concentration < 1% R39 obligatory | 0.02% < concentration < 0.2% R40f2 obligatory |
| T with R39/route of exposure | concentration > 5% R39 obligatory | 0.5% < concentration < 5% R40 obligatory | |
| Xn with R40/route of exposure | concentration > 5% R40 obligatory | ||
