Informational signs are used where instructions are needed. The heading says NOTICE in white letters on a green rectangle when the message is related to safety and on a blue rectangle for other messages. The body of the sign is white with the message printed in black.
Notice signs should not be used in place of Danger signs.
Caution signs shall have yellow as the predominating color; black upper panel and borders: yellow lettering of "caution" on the black panel; and the lower yellow panel for additional sign wording.
Black lettering shall be used for additional wording.
Signs must conform to the colors, symbols, lettering size, and proportions stated in 29 CFR 1910.145. Additional specifications for specific hazards are contained throughout the Work Smart Standards. Every warning sign must include the following components:
An approved heading that indicates the relative hazard.
A concise statement of the type of hazard.
A statement of what to do or not to do in the area.
Danger signs are used only where injury or damage is certain to occur if approved operating instructions and procedures are not followed. Personnel must be warned of the serious consequences of ignoring the message. The top of the sign says DANGER in white letters on a red oval that is edged by a rectangular black border. The body of the sign is white with the message printed in black.
