Paragraph 5.2 Gaseous preparations

Changes not yet applied. Later legislation changes this provision in ways not yet written into the text below:

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

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

  • the symbol Xn and phrase R 42/43 if this effect can be produced by inhalation and through contact with the skin.

The individual concentration limits specified in Table VA below, expressed as a volume/volume percentage, determine, when appropriate, the classification of the preparation.
