hazard sign
Caution symbol displayed
A hazard sign is a visual warning indicator—typically a symbol, icon, or placard—alerting people to potential dangers in an area.
These signs use standardized colors and shapes: yellow triangles for caution, red circles for prohibition, orange for biological hazards.
The hazard sign showed a figure slipping on a wet floor.
Common examples include radiation symbols, electrical warnings, and construction site notices.
