Red, black and white are the colors designated for danger signs. Caution signs have a yellow background, and the panel is black with yellow letters. Text used on the yellow background must be black. OSHA requires the wording of safety signs to indicate positive actions rather than negative, and to be concise and easy to read.
Biological hazard signs are 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".
