Gaseous preparations
4.2 For gases that produce such effects (R34, R35 or R36, R37, R38, R41), the individual concentration limits specified in Table IVA, expressed as a volume/volume percentage determine, when appropriate the classification of the preparation.
Table IVA
| Classificationof the substance (gas) | Classification of the preparation | |||
|---|---|---|---|---|
| C with R35 | C with R34 | Xi with R41 | Xi withR36, R37, R38 | |
| C with R35 | Concentration≥ 1% R35 obligatory | 0.2% ≤ concentration <1% R34 obligatory | 0.2%(*) | 0.02% ≤ concentration < 0.2% R36/37/38 obligatory |
| C with R34 | Concentration ≥ 5% R34 obligatory | 5%(*) | 0.5% ≤ concentration < 5% R36/37/38 obligatory | |
| Xi with R41 | concentration ≥ 5% R41 obligatory | 0.5% ≤ concentration <5% R36 obligatory | ||
| Xi withR36, R37, R38 | concentration ≥ 5% R36, R37, R38 obligatory as appropriate | |||
(*) According to the approved classification and labelling guide, when a substance or preparation is classified as corrosive and assigned the risk phrase R34 or R35, the risk of severe damage to the eyes is considered implicit and the risk phrase R41 is not included on the label. Consequently, if the preparation contains corrosive substances with R35 or R34 below the concentration limits for a classification of the preparation as corrosive, such substances can contribute to a classification of the preparation as irritant (R41) or irritant (R36).
