The pictogram shows a tree with no leaves and a dead fish to represent harm to the environment.
NOTE: Classification and labelling of the environmental hazard group is not required for WHMIS 2015. However, suppliers may voluntarily choose to disclose these hazards on labels and Safety Data Sheets (SDSs).
If the product only has this pictogram, the main concern is its toxicity for aquatic life. Aquatic hazards may include short-term (acute) hazards which looks at short-term impacts on various aquatic life forms (such as fish, crustaceans, algae, and aquatic plants).
It also includes long-term (chronic) hazards which looks at long-term (chronic) impacts on aquatic life forms such as bioaccumulation (buildup of a product in an organism) and degradation (persistence, or how long it will remain in the environment).
The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) has assigned this pictogram to be used for Hazardous to the aquatic environment - short-term (acute) - category 1, and Hazardous to the aquatic environment - long-term (chronic) - categories 1 and 2. Note that Hazardous to the aquatic environment - short-term (acute) - categories 2 and 3, and Hazardous to the aquatic environment - long-term (chronic) - categories 3 and 4 have no pictogram assigned.
The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) has assigned the following signal words and hazard statements:
Hazard Class and Category | Signal Word | Hazard Statement |
---|---|---|
Hazardous to the aquatic environment – short-term (acute) – category 1 | Warning | Very toxic to aquatic life |
Hazardous to the aquatic environment – short-term (acute) – category 2 | No signal word | Toxic to aquatic life |
Hazardous to the aquatic environment – short-term (acute) – category 3 | No signal word | Harmful to aquatic life |
Hazardous to the aquatic environment – long-term (chronic) – category 1 | Warning | Very toxic to aquatic life with long lasting effects |
Hazardous to the aquatic environment – long-term (chronic) – category 2 | No signal word | Toxic to aquatic life with long lasting effects |
Hazardous to the aquatic environment – long-term (chronic) – category 3 | No signal word | Harmful to aquatic life with long lasting effects |
Hazardous to the aquatic environment – long-term (chronic) – category 4 | No signal word | May cause long lasting harmful effects to aquatic life |
In addition to the specific hazards identified by the environment pictogram, it is important to remember that the product may have other hazards. If the product using this pictogram is also potentially hazardous to humans (e.g., physical or health hazards), it would have the other hazard pictograms to warn about its other properties.
