Paragraph 5.1 Other than gaseous preparations

Substances that produce such effects are classified as sensitizing and assigned:

• the symbol Xn and phrase R42 if this effect can be produced by inhalation,

• the symbol Xi and phrase R43 if this effect can be produced through contact with the skin,

• the symbol Xn and phrase R42/43 if this effect can be produced by inhalation and through contact with the skin.

The individual concentration limits specified in Table V determine, when appropriate, the classification of the preparation.
