PART IICONCENTRATION LIMITS TO BE USED IN THE EVALUATION OF HEALTH HAZARDS
An assessment must be made of the health effects that the use of a substance or a preparation might entail. For that purpose the dangerous health effects have been subdivided into:
| 1. | acute lethal effects; |
| 2. | non-lethal irreversible effects after a single exposure; |
| 3. | severe effects after repeated or prolonged exposure; |
| 4. | corrosive effects, irritant effects; |
| 5. | sensitising effects; |
| 6. | carcinogenic effects, mutagenic effects, toxic effects for reproduction. |
The systematic assessment of the dangerous health effects is expressed by means of concentration limits, expressed as weight/weight percentage except for gaseous preparations (Tables A) where they are expressed as a volume/volume percentage and in conjunction with the classification of a substance.
The classification of the substance is expressed either by a symbol and one or more risk phrases or by categories (category 1, category 2 or category 3) also expressed by risk phrases when substances are shown to be carcinogenic, mutagenic or toxic for reproduction. Therefore it is important to consider, in addition to the symbol, all the phrases denoting specific risks which are assigned to each substance under consideration.
Acute lethal effects
Other than gaseous preparations
1.1 The concentration limits fixed in Table 1 determine the classification of the preparation in relation to the individual concentration of the substance(s) present whose classification is also shown.
Table I
| Classificationof the substance | Classification of the preparation | ||
|---|---|---|---|
| T+ | T | Xn | |
| T+ with R26, R27, R28 | concentration ≥ 7% | 1% concentration < 7% | 0.1% concentration < 1% |
| T with R23, R24, R25 | Concentration ≥ 25% | 3% ≤ concentration < 25% | |
| Xn with R20, R21, R22 | concentration ≥ 25% | ||
The R phrases denoting risk shall be assigned to the preparation in accordance with the following criteria—
(i)the label shall include one or more of the above mentioned R phrases according to the classification used,
(ii)in general, the R phrases selected should be those applicable to the substance(s) present in the concentration which gives rise to the most severe classification.
Gaseous preparations
1.2 The concentration limits expressed as a volume/volume percentage in Table IA determine the classification of the gaseous preparations in relation to the individual concentrations of the gas(es) present whose classification is also shown.
Table IA
| Classificationof the substance (gas) | Classification of the preparation | ||
|---|---|---|---|
| T+ | T | Xn | |
| T+ with R26, R27, R28 | concentration ≥ 1% | 0.2% ≤ concentration <1% | 0.02% ≤ concentration<0.2% |
| T with R23, R24, R25 | concentration ≥ 5% | 0.5% ≤ concentration <5% | |
| Xn with R20, R21, R22 | concentration ≥ 5% | ||
The R phrases denoting risk shall be assigned to the preparation in accordance with the following criteria—
(i)the label shall include one or more of the above mentioned R phrases according to the classification used,
(ii)in general, the R phrases selected should be those applicable to the substance(s) present in the concentration which gives rise to the most severe classification.
Non-lethal irreversible effects after a single exposure
Other than gaseous preparations
2.1 For substances 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 II determine, when appropriate, the classification of the preparation.
Table II
| Classificationof the substance | Classification of the preparation | ||
|---|---|---|---|
| T+ | T | Xn | |
| T+ with R39/route of exposure | concentration ≥ 10% R39 (*) obligatory | 1% ≤ concentration <10% R39(*) obligatory | 0.1% ≤ concentration <1% R68(*) (†) obligatory |

(†) 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.
Severe effects after repeated or prolonged exposure
Other than gaseous preparations
3.1 For substances that produce severe effects after repeated exposure (R48/route of exposure), the individual concentration limits specified in Table III determine, when appropriate, the classification of the preparation.
Table III
| Classificationof the substance | Classification of the preparation | |
|---|---|---|
| T+ | Xn | |
| T with R48/ route of exposure | concentration ≥ 10% R48(*) obligatory | 1% ≤ concentration <10% R48(*) obligatory |
| Xn with R48/route of exposure | concentration ≥ 10% R48(*) obligatory | |
(*) In order to indicate the route of administration/exposure the combined R phraseslisted in Annex III of Council Directive 67/548/EEC shall be used.
Gaseous preparations
3.2 For gases that produce severe effects after repeated or prolonged exposure (R48/route of exposure), the individual concentration limits specified in Table IIIA, expressed as a volume/volume percentage, determine, when appropriate, the classification of the preparation.
Table IIIA
| Classificationof the substance (gas) | Classification of the preparation | |
|---|---|---|
| T+ | Xn | |
| T with R48/route of exposure | concentration ≥ 5% R48(*) obligatory | 0.5% ≤ concentration <5% R48(*) obligatory |
| Xn with R48/route of exposure | concentration ≥ 5% R48(*) obligatory | |
(*) In order to indicate the route of administration/exposure the combined R phraseslisted in Annex III of Council Directive 67/548/EEC shall be used.
Corrosive and irritant effects including serious damage to eye
Other than gaseous preparations
4.1 For substances that produce corrosive effects (R34, R35) or irritant effects (R36, R37, R38, R41), the individual concentration limits specified in Table IV determine, when appropriate, the classification of the preparation.
Table IV
| Classificationof the substance | Classification of the preparation | |||
|---|---|---|---|---|
| C with R35 | C with R34 | Xi with R41 | Xi withR36, R37, R38 | |
| C with R35 | concentration ≥ 10% R35 obligatory | 5% ≤ concentration <10% R34 obligatory | 5%(*) | 1% ≤ concentration <5% R36/38 obligatory |
| C with R34 | Concentration≥ 10% R34 obligatory | 10%(*) | 5% ≤ concentration <10% R36/38 obligatory | |
| Xi with R41 | concentration ≥ 10% R41 obligatory | 5% ≤ concentration<10% R36 obligatory | ||
| Xi withR36, R37, R38 | concentration ≥ 20%R36, R37, R38 are obligatory in the light of the concentration present if they apply to the substances under consideration | |||
(*) According to the approved classification and labelling guide, when a substance or preparation is classified as corrosive and assigned the risk phrase R34 or R35, the risk of severe damage to the eyes is considered implicit and the risk phrase R41 is not included on the label. Consequently, if the preparation contains corrosive substances with R35 or R34 below the concentration limits for a classification of the preparation as corrosive, such substances can contribute to a classification of the preparation as irritant (R41) or irritant (R36).
Note
Simple application of the conventional method to preparations containing substances classified as corrosive or irritant may result in under-classification or over-classification of the hazard, if other relevant factors (eg pH of the preparation) are not taken into account. Therefore, in classifying for corrosivity consider the advice given in the approved classification and labelling guide regarding classification as corrosive and paragraph 4(4)(b) and (c) of Part I of this Schedule.
Gaseous preparations
4.2 For gases that produce such effects (R34, R35 or R36, R37, R38, R41), the individual concentration limits specified in Table IVA, expressed as a volume/volume percentage determine, when appropriate the classification of the preparation.
Table IVA
| Classificationof the substance (gas) | Classification of the preparation | |||
|---|---|---|---|---|
| C with R35 | C with R34 | Xi with R41 | Xi withR36, R37, R38 | |
| C with R35 | Concentration≥ 1% R35 obligatory | 0.2% ≤ concentration <1% R34 obligatory | 0.2%(*) | 0.02% ≤ concentration < 0.2% R36/37/38 obligatory |
| C with R34 | Concentration ≥ 5% R34 obligatory | 5%(*) | 0.5% ≤ concentration < 5% R36/37/38 obligatory | |
| Xi with R41 | concentration ≥ 5% R41 obligatory | 0.5% ≤ concentration <5% R36 obligatory | ||
| Xi withR36, R37, R38 | concentration ≥ 5% R36, R37, R38 obligatory as appropriate | |||
(*) According to the approved classification and labelling guide, when a substance or preparation is classified as corrosive and assigned the risk phrase R34 or R35, the risk of severe damage to the eyes is considered implicit and the risk phrase R41 is not included on the label. Consequently, if the preparation contains corrosive substances with R35 or R34 below the concentration limits for a classification of the preparation as corrosive, such substances can contribute to a classification of the preparation as irritant (R41) or irritant (R36).
Note
Simple application of the conventional method to preparations containing substances classified as corrosive or irritant may result in under-classification or over-classification of the hazard, if other relevant factors (eg pH of the preparation) are not taken into account. Therefore, in classifying for corrosivity, consider the advice given in the approved classification and labelling guide regarding classification as corrosive and paragraph 4(4)(b) and (c) of Part I of this Schedule.
Sensitising effects
Other than gaseous preparations
5.1 Preparations that produce such effects are classified as sensitising 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 individual concentration limits specified in Table V determine, when appropriate, the classification of the preparation.
Table V
| Classification of the substance | Classification of the preparation | |
|---|---|---|
| Sensitising with R42 | Sensitising with R43 | |
| Sensitising with R42 | concentration ≥ 1% R42 obligatory | |
| Sensitising with R43 | concentration ≥ 1% R43 obligatory | |
Gaseous preparations
5.2 Gases that produce such effects are classified as sensitising 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 by inhalation and through contact with the skin.
The individual concentration limits specified in Table VA expressed as a volume/volume percentage, determine, when appropriate, the classification of the preparation.
Table VA
| Classification of the substance (gas) | Classification of the preparation | |
|---|---|---|
| Sensitising with R42 | Sensitising with R43 | |
| Sensitising with R42 | concentration ≥ 0.2% R42 obligatory | |
