gases classified for acute toxicity in Category 1 or 2 in dangerous amounts, for example salts of hydrogen cyanide, sodium azide.

AUH066: Repeated exposure may cause skin dryness or cracking

For substances and mixtures which may cause concern as a result of skin dryness, flaking or cracking but which do not meet the criteria for skin irritancy.

AUH070: Toxic by eye contact

For substances or mixtures where an eye irritation test has resulted in overt signs of systemic toxicity or mortality among the animals tested, which is likely to be attributed to absorption of the substance or mixture through the mucous membranes of the eye. The statement should also be applied if there is evidence in humans for systemic toxicity after eye contact.

The statement should also be applied where a substance or a mixture contains another substance labelled for this effect, if the concentration of this substance is equal to, or greater than 0.1 %.

AUH071: Corrosive to the respiratory tract

For substances and mixtures in addition to classification for inhalation toxicity, if data is available that indicates the mechanism of toxicity was corrosivity.

In addition to an appropriate acute toxicity symbol, a 'corrosion' symbol (similar to the 'corrosion' symbol used for skin and eye corrosivity) is added along with the hazard statement AUH071: Corrosive to the respiratory tract.

For substances and mixtures in addition to classification for skin corrosivity, if no acute inhalation test data is available and which may be inhaled.

APPENDIX E – PRECEDENCE RULES OF LABEL ELEMENTS

This appendix provides information on the rules of precedence of certain label elements, and general guidance for when redundant elements may be omitted from a label.
Duplication or redundancy of label elements may occur where a hazardous chemical meets the criteria for more than one hazard class or category. Duplication of an element may occur where:
    * a specific precautionary statement applies to several hazard categories into which a particular chemical is classified
    * an element may become redundant because a more stringent control applies to another hazard category (for example, the type of PPE required).
Duplicate or redundant information should not be included on a label.

Multiple Hazards and Precedence of Hazard Information

Hazard pictograms
The following rules apply for the use of hazard pictograms on a label:

    * where a transport of dangerous goods class label (pictogram) is required on the container to meet transport regulations, the equivalent hazard pictogram, as specified in the GHS, should not appear
    * if the skull and crossbones hazard pictogram applies, the exclamation mark hazard pictogram should not appear
    * if the corrosive hazard pictogram applies, the exclamation mark hazard pictogram should not appear if it is used to communicate
