The flame over circle pictogram is used for the following hazard classes and categories.
WHMIS PICTOGRAMS WHMIS SYMBOLSWHMIS Symbols (previously referred to as WHMIS Pictograms) are a cornerstone of the WHMIS system. Symbols represent an idea that is conveyed using a picture without words. A set of standardized pictograms is used by WHMIS on product labels and data sheets to easily show the user of a hazardous product what type of hazard is present.These hazard images convey meaning quickly and accurately for workers. Just as a STOP sign instantly and accurately conveys the message for the driver to stop, seeing a WHMIS symbol can tell a worker a lot about that hazard they need to be aware of. In our highly digital world people have become accustomed to the use of symbols, icons and images on our communication devices. When someone sees a symbol, such as a phone, they know someone is calling, a thumbs up means a 'like'. Similarly, when an employee sees a symbol, such as the Skull and Crossbones, they instantly know this product is toxic and can cause death.As a result of the alignment of the Workplace Hazardous Materials Information System (WHMIS), with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), the old (1988) WHMIS hazard symbols have been replaced by universally acknowledged WHMIS Pictograms.
You will find pictograms on Product Supplier Labels and on Safety Data Sheets (SDSs).Generally, WHMIS Pictograms are a simplified graphic image to identify the type of hazard of various hazardous materials. Universally recognized, these standardized images are easy to understand and the hazardous nature of the product such as explosive, corrosive, flammable, etc., can be understood quickly and the correct precautions can be taken in handling the product, reducing the workers risk in interacting with the product.All WHMIS 2015 pictograms (previously called, WHMIS Symbols) are made of a distinctive red diamond border with the icon representing the hazard associated with a product (such as corrosive, health hazard or fire) inside the border. Together, the border and the symbol are called a WHMIS pictogram and are assigned to a specific hazard category or class. NOTE: There are some hazardous products that meet the criteria for a hazard class or category but do not require a pictogram. For complete details on these WHMIS 2015 classes visit the.
WHMIS 2015 Symbols (Pictograms) - What's Changed. The new WHMIS pictograms are contained within a red diamond shaped border vs the black circle borders of the WHMIS 1988 symbols. This change is more effective in making the symbol more visible as it now stands out from the red border. There are no longer letter-based symbols like the 'Exclamation T' for other Toxic effects or the letter 'R' for Dangerously Reactive.
Hazard pictograms form part of the international Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Two sets of pictograms are included within the GHS: one for the labelling of containers and for workplace hazard warnings, and a second for use during the transport of dangerous goods. Either one or the other is chosen, depending on the target audience, but the two are not used together.[1] The two sets of pictograms use the same symbols for the same hazards, although certain symbols are not required for transport pictograms. Transport pictograms come in wider variety of colors and may contain additional information such as a subcategory number.
Hazard pictograms are one of the key elements for the labelling of containers under the GHS, along with:[2]
- an identification of the product;
- a signal word – either Danger or Warning – where necessary
- hazard statements, indicating the nature and degree of the risks posed by the product
- precautionary statements, indicating how the product should be handled to minimize risks to the user (as well as to other people and the general environment)
- the identity of the supplier (who might be a manufacturer or importer)
The GHS chemical hazard pictograms are intended to provide the basis for or to replace national systems of hazard pictograms. It has still to be implemented by the European Union (CLP regulation) in 2009.
The GHS transport pictograms are the same as those recommended in the UN Recommendations on the Transport of Dangerous Goods, widely implemented in national regulations such as the U.S. Federal Hazardous Materials Transportation Act (49 U.S.C. 5101–5128) and D.O.T. regulations at 49 C.F.R. 100–185.
