Warning icon displayed
A hazard symbol is a standardized pictogram warning of danger—the skull and crossbones for poison, the flame for flammable materials, the radiation trefoil.
These appear on chemical containers, workplace signs, and product labels to communicate risks across language barriers: Check the hazard symbols before handling any chemicals.
