Paragraph 5 Sensitizing Effects
Solid and liquid preparations—Substances that produce such effects are classified:
-
at least as harmful (Xn) and assigned R42 if this effect can be produced by inhalation,
-
at least as irritant (Xi) and assigned R43 if this effect can be produced through contact with the skin,
-
at least as harmful (Xn) and assigned R42/43 if this effect can be produced in both these ways.
The individual concentration limits specified in Table V determine, when appropriate, the classification of solid and liquid preparations and shall determine which particular risk phrases are to be assigned to them.
TABLE V
| Classification of the substance | Classification of the preparation and standard risk phrase | |
|---|---|---|
| At least Xn and R42 | At least Xi and R43 | |
| At least Xn and R42 | conc. ≥ 1% R42 obligatory | |
| At least Xi and R43 | conc. ≥ 1% R43 obligatory | |
| At least Xn and R42/43 | conc. ≥ 1% R42/43 obligatory | |
Gaseous Preparations—Gases that produce such effects are classified:
-
at least as harmful (Xn) and assigned R42 or R42/43 as appropriate. The individual concentration limits specified in Table VA below, expressed as a volume/volume percentage determine, when appropriate, the classification of gaseous preparations and shall determine which particular risk phrases are to be assigned to them.
TABLE VA
| Classification of the substance (gas) | Classification of the gaseous preparation and standard risk phrase | |
|---|---|---|
| At least Xn with R42 | ||
| At least Xn with R42 | conc. ≥ 0.2% R42 obligatory | |
| At least Xn with R42/43 | conc. ≥ 0.2% R42/43 obligatory | |
