There are strict regulations concerning Sulphuric Acid labelling as laid down in the CHIP Regulations. Information on the label must include the name, full address and telephone number of the supplier. In addition to this, the name of the substance must be recorded in line with the specification of 3.2 of the CLP Regulations.
Relevant Risk and Safety Phrases must appear on the label, plus any EC number, as appropriate. Exemptions to the labelling requirements are available for some classes of hazardous substances in small amounts but Sulphuric Acid being classed as ‘Corrosive’ does not fall into these categories.
Current Regulations concerning Sulphuric Acid labelling (CLP Regulations) are due to change on 1 December 2010. At this point, the format of labelling under the CLP Regulations will be changed. Instead, the new labelling format will be as laid out in the GHS (Globally Harmonised System).
Under CLP Regulations, the GHS Classification of Sulphuric Acid will be:-
Hazard Class ‘Skin corrosion’
Category ‘1A’
Under the new GHS system, Sulphuric Acid labelling must include the name, address and telephone number of the supplier will still be listed and the product identifiers will stay the same. However, the phrases ‘EC number’ or ‘EC label’ will no longer be stated.
The word ‘DANGER’ or ‘WARNING’ will appear on the label together with Hazard Statement and Precautionary Statement. The relevant Signal Word for Sulphuric Acid will be ‘DANGER’.
Pictograms representing the hazards will appear in the form of a square set at a point with a white background and red border. These will cover at least one fifteenth of the label area and be a minimum size of 1cm 2 (100 mm 2). The relevant Pictogram Code for Sulphuric Acid will be GHS 05.
Precautionary Statements are the phrases used to describe the recommended measures to be taken to reduce adverse effects from exposure. Precautionary Statements will carry a letter ‘P’ and three digits.
Hazard Statements are the phrases used to describe the nature of the hazard and where appropriate, the degree of hazard. Hazard Statements will be given a letter ‘H’ and a three digit code. The relevant Hazard Statement for Sulphuric Acid will be:-
H314 ‘Causes severe skin burns and eye damage’.
In order to improve readability of the label, it will be possible to combine Precautionary Statements and Hazard Statements into one.
As can be seen from the above, strict regulations are in place with regard to Sulphuric Acid labelling and in order to comply with regulations, these must be strictly adhered to.
