Understanding Safety Signs
DANGER
"DANGER" indicates an immediate hazard which, if not avoided, will result in death or serious injury. Danger signs should be limited to the most extreme situations. OSHA previously included an alternate header design which featured the word DANGER within a red oval on a black background. This header has been eliminated by ANSI. Read more...
WARNING
"WARNING" indicates a hazardous situation which, if not avoided, could result in death or serious injury. OSHA previously included an alternate header design which featured the word WARNING within a black hexagonal shape on an orange background. This header has been eliminated by ANSI. Read more...
CAUTION
"CAUTION" indicates a hazardous situation which, if not avoided, may result in minor or moderate injury. OSHA previously included an alternate header design which featured the word CAUTION written in yellow within a black rectangular shape. This header has been eliminated by ANSI. Read more...
NOTICE
"NOTICE" is used to address practices not related to personal injury. NOTICE signs provide general information that is important or relevant to a building, an area, a machine, or equipment. While NOTICE must never used for personal injury hazards or warnings, it can be used to indicate possible equipment or property damage. Read more...

Biological Hazards
According to OSHA §1910.145(e)(4), "The biological hazard warning shall be used to signify the actual or potential presence of a biohazard and to identify equipment, containers, rooms, materials, experimental animals, or combinations thereof, which contain, or are contaminated with, viable hazardous agents… presenting a risk or potential risk to the well-being of man."
