2.1 Classification of the substance or mixture

Silver as such is classified as H400 and H410, according to ECHA (http://clp- inventory.echa.europa.eu/DetailsOfNotifAndLabelling.aspx?SubstanceID=99642&NotificationID= 14308365). Ag NP in the environment release Ag ions: it behaves more as a soluble salt than an insoluble metal. Therefore, both the classification of silver metal and the classification of silver nitrate can be used to propose a classification for nano silver, also taking into account available nano-specific literature, and the fact that this a powder product.

2.3 Other hazards

Nano Ag, as a powder, during handling can form dust. To measure this parameter, dustiness is measured. However, it is a value not easy to find. According to the value reported in section 9, the dustiness class established by the software Stoffenmanager nano3 is medium (lowest possible value in the software).
