SCHEDULE 3 PROVISIONS FOR CLASSIFYING DANGEROUS PREPARATIONS

PART II CONCENTRATION LIMITS TO BE USED IN THE EVALUATION OF HEALTH HAZARDS

Gaseous preparations

2.2  For gases that produce non-lethal irreversible effects after a single exposure (R39/route of exposure, R68/route of exposure), the individual concentration limits specified in Table IIA, expressed as a volume/volume percentage, determine, when appropriate, the classification of the preparation.

Table IIA

Classificationof the substance (gas)	Classification of the preparation
	T+	T	Xn
T+ withR39/route ofexposure	concentration ≥ 1% R39(*) obligatory	0.2% ≤ concentration <1% R39(*) obligatory	0.02% ≤ concentration<0.2% R68(*)(†) obligatory
T with R39/route of exposure		concentration ≥ 5% R39(*) obligatory	0.5% ≤ concentration <5% R68(*)(†) obligatory
Xn with R68/route ofexposure			concentration ≥ 5% R68 (*)(†) obligatory

(*) In order to indicate the route of administration/exposure the combined R phrases listed in Annex III of Council Directive 67/548/EEC shall be used.

• (†) R68 here refers to substances classified as harmful. Concentration limits for substances required to be labelled R68 but classified as mutagenic are given in Table VI.
