1 Classification and Labelling of Substances for health hazards

2 Identification of informationen GHS/CLP does not foresee the use of uniform test methods Different test methods - as long as they are scientifically sound and validated according to international procedures New tests on animals shall be avoided wherever possible (in accordance with REACH) All available data shall be evaluated first 2

3 General information Existing human data (eg: accidental or occupational exposure data, epidemiological studies, clinical studies, ) Ex-vivo methods In-vitro methods In-silico methods (Grouping, Read-across, (Q)SARs) Weight of evidence from several independent d sources of information as a basis for classification Only if this information is not sufficient new animal tests shall be performed 3

9 Serious eye damage/eye irritation CLP-Reg: Category 1 Category 2 H318: Causes serious eye damage Warning H319: Causes serious eye irritation DSD: Irritant (Xi) R41 R36 9

Respiratory or skin sensitisation CLP-Reg :

difficulties if inhaled Sensitising (Xn) Warning

10 Respiratory or skin sensitisation CLP-Reg : Respiratory sensitisation (Category 1) Skin sensitisation (Category 1) DSD: H334: May cause allergy or asthma symptoms or breathing difficulties if inhaled Sensitising (Xn) Warning H317: May cause an allergic skin reaction Sensitising (Xi) R42 R43 10

11 CMR Classification criteria for CMR properties according to CLP and DSD similar: Category 1 => Category 1A: classification based on positive evidence from human epidemiological studies (no substance classified as cat. 1A so far!) Category 2 => Category 1B: classification based on positive results from in vivo tests Category 3 => Category 2: positive evidence obtained from experiments in mammals and/or in vitro experiments and not sufficiently convincing to place in Cat. 1A or 1B R64 => H362: based on human and animal evidence 11

12 CMR CLP-Reg : Category 1A Category 1B Category 2 Additional category for effects on and via lactation No pictogram No signal word Warning DSD: Category 1 (T) Category 2 (T) Category 3 (Xn) R64 12

13 Specific target organ toxicity (STOT), single exposure = non lethal STOT arising from a single exposure to a subst/mix All significant health effects are included if not specifically addressed in another hazard class (e.g. acute toxicity, CMR, ) reversible & irreversible immediate &/or delayed effects significant changes in a single organ or biological system or generalised changes of a less severe nature involving several organs Specific target organ toxicity (STOT), repeated exposure = STOT including lethal effects arising from repeated exposure All significant health effects that can impair function reversible & irreversible; immediate &/or delayed effects significant changes in a single organ or biological system or generalised changes of a less severe nature involving several organs 13

19 Aspiration hazard Classification is based on human cases for some hydrocarbons (e.g. petroleum distillates) and chlorinated hydrocarbons Classification criteria refer to kinematic Viscosity (mm 2 /s) Significant change to old system: CLP-Regulation: classification in Category 1 if kinematic viscosity 20,5 5 mm 2 /s ous Substances Directive: classification with R65 based on kinematic viscosity 7 mm 2 /s Aspiration means the entry of a liquid or solid substance or mixture directly (through the oral or nasal cavity) or indirectly (from vomiting) into the trachea and lower respiratory systems Aspiration toxicity includes severe acute effects such as chemical pneumonia, pulmonary injury or death following aspiration 19
