ACUTE LETHAL EFFECTS

Solid and liquid preparations

1.—(1) —The concentration limits fixed in Table 1 determine the classification of solid and liquid preparations in relation to the individual concentration of the substance(s) present whose classification is also shown.

TABLE I

Classification of the substance	Classification of the preparation
T+	T	Xn
The risk phrases denoting risk shall be assigned to the preparation in accordance with the following criteria: the label shall include one or more of the above-mentioned risk phrases according to the classification used, in general, the risk phrases selected should be those applicable to the substance(s) present in the concentration which gives rise to the most severe classification.
T+ with R26, R27, R28	conc. ≥ 7%	1% ≤ conc. < 7%	0.1% ≤ conc. < 1%
T with R23, R24, R25		conc. ≥ 25%	3% ≤ conc. < 25%
Xn with R20, R21, R22			conc. ≥ 25%

(2) Gaseous Preparations—The concentration limits expressed as a volume/volume percentage in Table 1A below determine the classification of gaseous preparations in relation to the individual concentration of the gases present whose classification is also shown.

TABLE IA

Classification of the substance (gas)	Classification of the gaseous preparation
T+	T	Xn
T+ with R26	conc. ≥ 1%	0.2% ≤ conc. < 1%	0.02% ≤ conc. < 0.2%
T with R23		conc. ≥ 5%	0.5% ≤ conc. < 5%
Xn with R20			conc. ≥ 5%
