GHS FAQs

GHS stands for the Globally Harmonized System of Classification and Labelling of Chemicals. It was developed by the United Nations and its goal is to standardize and harmonize the classification and labelling of chemicals to give universally understood warnings to users. The three major areas of impact are:

Hazard Classification: Definitions of hazard now include specific criteria for classifying health and physical hazards as well as classification of mixtures. It will result in more accurate safety data sheets. Labels: Chemical manufacturers, importers and distributors must use labels that include a harmonized signal word, pictograms, and hazard statement for each hazard class and category. Precautionary statements must also be provided. Safety Data Sheets: Now have a specific 16-section standardized format.

GHS affects chemical manufacturers, importers, distributors and any company that has hazardous chemicals in the workplace.

Chemical manufacturers must re-classify their hazardous chemicals based on a common system of chemical classification defined by GHS. They must update their safety data sheets and also use GHS-compliant labels to identify their hazardous chemicals. Chemical Importers/Distributors must ensure the hazardous chemicals they sell have GHS-compliant safety data sheets and GHS-compliant labels. Employers with hazardous chemicals in the workplace must ensure that they have safety data sheets and labels for their exposed workers and that they are trained to handle the chemicals properly.

In relation to the hazard pictograms, CLP links the size of the pictograms to the minimum dimensions of the custom label: each hazard pictogram shall cover at least one fifteenth of the surface area of the label dedicated to obligatory labelling information, i.e. any label elements required by CLP Article 17,25 and 32(6), but the minimum area shall not be less than 1cm², see section 1.2.1.2 of Annex I to CLP. The idea behind this is that the label size and the size of the pictograms should remain proportional to the size of the packaging.

If you do not require BS5609 Section 3 certification, you can use a standard colour laser printer with Avery® Ultra Heavy Duty Labels and have excellent durability. For best results use the Label setting on your printer.

If you require BS5609 Section 3 certification, Avery Ultra Heavy Duty Labels are BS5609 Section 3 certified with the following printers: OKI printer models C610, C711, C9655, C931, ES6410, ES7411, ES9431 and ES9541.

Yes. If a chemical is supplied to the workplace with a GHS label, it must be maintained. If the chemical is transferred to a secondary container (i.e. tank or spray bottle) that remains in the workplace, then employers can choose to have it labelled it with the same information from the original GHS shipping label or safety data sheet. However, employers can also choose to use an alternative system such NFPA or HMIS. If using an alternative system, it is the responsibility of the employer to ensure that the information is consistent with GHS and that workers understand specific physical and health hazards.

If the chemical is transferred to a "portable" secondary container for use by only the person who transferred it during the same work shift, then it is considered "immediate use" and a label is not required.

Yes, Avery® Ultra Heavy Duty Labels are perfect for any application indoor or outdoor where high durability and adhesive performance is required. These labels are underwater submersible and resistant to chemicals, abrasion, weather, sunlight, tearing and temperature. Some alternate uses include: Hazard Warning Labels & Signs Lab test Tubes Arc Flash Labels Vat and Tank Labels Automotive Labels Marine equipment labels Outdoor work labels
Avery® Ultra Heavy Duty Labels work on multiple surfaces including: plastic, metal, painted surfaces, fibreboard, polycarbonate, glass, etc.
