Labelling

Adequate labelling of solutions that will be stored in the science or chemistry classroom.

Table of Contents

Chemicals That Need to be Labelled

New chemicals ordered from a supplier are already labelled in accordance with regulations. However, solutions that are made locally also require labelling. As a minimum, the label should contain the name and concentration of the solution, and sufficient hazard information to ensure proper use. For solutions that will be stored for some time or used in the classroom, it is recommended to label them with hazard information similar to that which is found on labels made according to the CLP regulation. Old chemicals that do not have a CLP label need to be relabelled.

Making a Label for a Solution

A label should include the following elements:

  • Product identifier
  • Hazard information
    • Hazard pictogram(s)
    • Signal word
    • Hazard statement(s)
    • Precautionary statement(s)
  • Information about who made the solution and when it was made

Product Identifier

Chemical products have a chemical name and an identification number, such as the CAS number. This information is called the product identifier. The product identifier can be found in the Classification and Labelling Inventory, on the container of the original product from the supplier, and in the safety data sheet. In addition to the product identifier, the chemical formula and the concentration of the dissolved substance should be given on the label. If the solvent is something other than water, the chemical name of the solvent should be included in the title or in a subtitle. 

Hazard Information

Hazard information includes hazard pictogram(s), signal word, hazard statement(s) and precautionary statement(s). The hazard information should be kept together on the label. If there are no hazard classes assigned to the solution, the label should read “Not subject to classification”. If a solution contains other solvents than water, or more than one substance, the label must also include the hazard information for these substances.

Information About Who Made the Solution

For solutions made in school, the label should include the date of production and the name of the person who made the solution.

Hazard Information on Common Chemicals

The list of chemicals below contains hazard information on some common solutions used in chemistry education. The hazard information depends on the concentration of the solution, so make sure to choose the right concentration interval.

If the substance is not in the list below, try to find a safety data sheet for a solution with the same substance and concentration. Use the hazard pictogram(s), signal word and hazard statements in the safety data sheet on the label. Choose the precautionary statements that are relevant to how the solution will be used in the classroom. If a safety data sheet with the right concentration is not available, use a safety data sheet for a more concentrated solution or for the pure substance. In this case, this may over classify the solution. However, better safe than sorry.

The CheSSE Label Generator

The label generator generates labels with the appropriate label elements. These are based on harmonized classification and may differ slightly from information in safety data sheets from different suppliers.

When clicking on a chemical in the list, the classification for different concentration intervals is shown. It is then possible to generate a label by clicking “generate label” for the right concentration interval. The generated label can be copied and pasted for example into a textbox in a Word document. In this way it is possible to print several labels on the same page.
