New self-classification of nitric acid

12 December 2016

 

 

Based on new data available, nitric acid is self-classified for acute toxicity by inhalation in category 3. This proposed classification will be included in the updated REACH registration dossier (update planned November 2016) and will need to be included in the updated Safety Data Sheet.

According to the calculation rules outlined in the CLP Regulation (Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures), this will be the resulting classification for nitric acid and its aqueous solutions:
Nitric acid concentration
Classification category
<=13%                    No classification
>13% - <=26%      Acute tox. cat. 4
>26% - <=100%    Acute tox. cat. 3
