All requirements concening Nitric Acid labelling are covered by 'The Chemicals (Hazard Information and Packaging for Supply) Regulations 2009 which are often abbreviated to 'CHIP Regulations'.  These regulations govern all labelling requirements for dangerous substances and preparations, including Nitric Acid labelling, which must be supply the following information:-

Nitric Acid LabellingFor some classes of hazardous substances in small amounts, there are exemptions from certain sections of the labelling requirements.  However, Corrosive substances are not exempt and due to its Corrosive classification, this means that Nitric Acid labelling is not exempt from the requirements.

Currently, EU classification symbols are printed in black on an orange background.  The size, incuding the background must be at least 10% of the overall label area, with a minimum size of 100 square millimetres.

Currently, a 'Corrosive' symbol is represented by a hand and surface being attacked by a liquid, with the corresponding letter 'C'.  'Corrosive' liquids such as Nitric Acid can be classified as either Risk Phrase 34 or Risk Phrase 35 depending on the concentration of material.

However, from 1 December 2010, new regulations will come into place and the current regulations will be replaced by a Globally Harmonised System (often abbreviated to 'GHS') which will be covered by the CLP Regulations.  EC Number 1212/2008 refers.  All existing requirements for HNO3 labelling will be replaced by the new system which requires the following information:-

Hazard Pictograms will be in the form of a square set at a point with a white background and a red border.  These shall cover at least one fifteeenth of the total label area and shall be a minimum of one square centimetre or one hundred square millimetres.

Precautionary Statements are phrases which describe recommended measures that should be taken to minimise or prevent adverse effects resulting from exposures to  hazardous products or improper storage or handling of hazardous products.  Precautionary Statements apply to HNO3 labelling and there are five categories of Precautionary Statement, including:-

Precautionary Statements are assigned the letter 'P' with a three digit code.  For example 'P102' means 'Keep out of reach of children'.

Hazard Statements are statements assigned to hazard classes and categories that describe the nature of the hazard and where appropriate, the degree of hazard.  Hazard Statmenets are assigned the letter 'H' and a three digit code.  For example 'H240' means 'Heating may cause an explosion'.  Each Hazard Statement will have a recommended number of Precautionary Statements.

In order to improve readability and save on label space, the Hazard Statements and Precautionary Statements may be combined on the label.  The manufacturers may also provide directions for use on the label.
