Index number: 016-010-00-3
Annex VI tables 3.1 and 3.2 (ATP Inserted / Updated: CLP00)

H400: Aquatic Acute 1 – Very toxic to aquatic life

N, R50 - Very toxic to aquatic life

 

Seveso II classification

Main Seveso category: 2
Other Seveso categories: 9

 

Self classification

1. According to Commission Regulation (EU) No 286/2011 of 10 March 2011 amending, for the purposes of its adaptation to technical and scientific progress, Regulation (EC) No 1272/2008

 

Acute and chronic classification

Based on the environmental exposure assessment, the Na2Sx will disassociate and react almost instantly when entering the environment to SO4a naturally occurring relatively harmless substance.
