GHS Pictogram for Environmental Hazard - Blue Diamond Symbol Explained #1691202 (License: Personal Use)

The image shows a Globally Harmonized System (GHS) pictogram: a blue diamond with a white stylized face-two squares for eyes and a horizontal bar for a mouth-used to denote environmental hazards, particularly aquatic toxicity. Though not part of the official UN-recommended nine GHS pictograms, this variant is sometimes used regionally or in supplementary labeling to signal ecological risk. It warns that the substance may cause long-term adverse effects in aquatic environments.

This image is typically used in safety data sheets (SDS), chemical labeling guides, occupational health training, and regulatory compliance documentation. It matches user intent for understanding non-standard but recognized hazard symbols, especially in environmental safety contexts.
