NON-LETHAL IRREVERSIBLE EFFECTS AFTER A SINGLE EXPOSURE

Solid and liquid preparations

2.—(1) —For substances that produce non-lethal irreversible effects after a single exposure (R39, R40), the individual concentration limits specified in Table II determine, when appropriate, the classification of solid and liquid preparations and shall determine which particular risk phrases are to be assigned to them.

Gaseous Preparations

(2) —For gases that produce non-lethal irreversible effects after a single exposure (R39, R40), the individual concentration limits specified in Table IIA, 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.
