Paragraph 4.2 Gaseous preparations
For gases that produce such effects (R34, R35 — or R36, R37, R38, R41), the individual concentration limits specified in Table IVA below, expressed as a volume/volume percentage determine, when appropriate, the classification of the preparation.
TABLE IV
| Classification of the substance | Classification of the preparation | |||
|---|---|---|---|---|
| C with R35 | C with R34 | Xi with R41 | Xi with R36, R37, R38 | |
(*) According to the approved classification and labelling guide (paragraph 57) when a substance or preparation is classified as corrosive and assigned the risk phrase R34 or R35, the risk phrase R41 does not need to be included. 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). Therefore when the formulae of paragraphs 11(b) and 13(b) of Part I of this Schedule are applied the following concentration limits must be used, unless different values are fixed in the approved supply list.
| ||||
| C with R35 | concentration > 10% R35 obligatory | 5% < concentration < 10% R34 obligatory | f1 | 1% < concentration < 5% R36/38 obligatory |
| C with R34 | concentration > 10% R34 obligatory | 5% < concentration < 10% R36/38 obligatory | ||
| Xi with R41 | concentration > 10% R41 obligatory | 5% < concentration < 10% | ||
| Xi with R36, R37, R38 | concentration > 20% R36, R37, R38 are obligatory in the light of the concentration present if they apply to the substances under consideration | |||

According to the approved classification and labelling guide (paragraph 57) when a substance or preparation is classified as corrosive and assigned the risk phrase R34 or R35, the risk phrase R41 does not need to be included. 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).
Therefore when the formulae of paragraphs 11(b) and 13(b) of Part I of this Schedule are applied the following concentration limits must be used, unless different values are fixed in the approved supply list.
- (a)
when formula 11(b) is applied the limit values for LXiR41 are:
-
10% for the substances XiR41,
-
10% for the substances C R34,
-
5% for the substances C R35;
-
- (b)
when the formula 13(b) is applied the limit values for LXiR36 are:
-
20% for the substances Xi R36,
-
5% for the substances Xi R41,
-
5% for the substances C R34,
