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

An assessment shall 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

1.    

Other than gaseous preparations

1.1  The concentration limits fixed in Table I determine the classification of the preparation in relation to the individual concentration of the substance(s) present whose classification is also shown.

Table I
Classification of 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
Classification of the substance 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

2.    

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.

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

Corrosive and irritant effects including serious damage to eye

4.    

Other than gaseous preparations

4.1  For substances that produce corrosive effects (R34, R35) or irritant effect (R36, R37, R38, R41), the individual concentration limits specified in Table IV determine, when appropriate, the classification of the preparation.

Table IV
Classification of the substance Classification of the preparation
C with R35 C with R34 Xi with R41 Xi with R36, R37 R38
a

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).

C with R35 concentration ≥ 10% R35 obligatory 5% ≤ concentration < 10% R34 obligatory 5%a 1% ≤ concentration < 5% R36/38 obligatory
C with R34 concentration ≥ 10% R34 obligatory 10%a 5% ≤ concentration < 10% R36/38 obligatory
Xi with R41 concentration ≥ 10% R41 obligatory 5% ≤ concentration < 10% R36 obligatory
Xi with R36, R37, R38 concentration ≥ 20% R36, R37, R38 are obligatory in the light of the concentration present if they apply to the substances under consideration

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 (e.g. 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

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).

C with R35 concentration ≥ 1% R35 obligatory 0.2% ≤ concentration < 1% R34 obligatory 0.2%a 0.02% ≤ concentration < 0.2% R36/37/38 obligatory

Xi with R41 concentration ≥ 5% R41 obligatory 0.5% ≤ concentration < 5% R36 obligatory
Xi with R36, R37, R38 concentration ≥ 5% R36, R37, R38 are obligatory as appropriate

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 (e.g. pH of the preparation) are not taken into account. Therefore, in classifying for corrosivity, consider the advice given in approved classification and labelling guide regarding classification as corrosive and paragraph 4(4)(b) and (c) of Part I of this Schedule.

Sensitising effects

5.    

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.

Sensitising with R42 concentration ≥ 0.2% R42 obligatory

Other than gaseous preparations

6.1  For substances that produce such effects and for which specific concentration limits do not yet appear in Table 3.2 of part 3 of Annex VI of the CLP Regulation, concentration limits laid down in Table VI shall determine, where appropriate, the classification of the preparation.

The following symbol and risk phrases are assigned:
