Exposure Assessment do not exhibit any particularly hazardous physical-chemical properties, and users are not considered to be at risk due to the physical-chemical properties of this active substance. No classification and labelling is proposed for liquid argon, given the lack of critical endpoints in terms of adverse effects on human health and of physico-chemical properties. No critical end points in terms of adverse effects on the environment have been identified for liquid argon. 8. Recommendations on Risk Management does not have particularly hazardous physical and chemical properties, and therefore it is assumed that users of the product are not at risk. 9. Classification and labelling 9.1 Classification Classification according to Regulation (EC) No 1272/2008: 9.2 Labelling Labelling according to Regulation (EC) No 1272/2008: Not classified No labelled. 10. Registartion information Registration Number: no data available 11.
