Precautions and Transportation
Nitric acid is harmful to animals and plant tissues, provokes the ignition of flammable materials. Causes skin redness, irritates the mucous membranes of the nose, eyes, mouth, and also causes problems with the respiratory tract.

Technical nitric acid 57% dissolves some metals well, while at higher concentrations the metals do not dissolve.
This property is used for cleaning pipelines from metal salts.
Nitric acid technical 57% is used in almost all industries.
