What H411 means
H411 is the GHS (Globally Harmonized System) hazard statement “Toxic to aquatic life with long lasting effects.” It belongs to the Hazardous to the aquatic environment (chronic) hazard class and appears in Section 2 of a Safety Data Sheet and on the product label when a substance or mixture meets the classification criteria for that class and category.
H411 is a lower-tier statement to which GHS assigns no pictogram or signal word on its own. It still communicates a real hazard and belongs on the SDS and label where the criteria are met.
