How to read it

In the ANSI Z535 standards NOTICE follows DANGER, WARNING and CAUTION, and unlike them it isn’t about injury: ANSI describes it as addressing practices not related to physical injury. It is also the only signal word set in italics: ANSI’s product-label standard, Z535.4, sets signal words in upper-case sans serif letters and NOTICE in italicized upper-case sans serif. Safety instructions have a panel of their own, white letters on green.

Also searched as: ansi notice, notice signal word.

These explain what a sign’s signal word, colour and shape mean. For what to do in a hazard area, follow the site’s own signs, instructions and trained staff.

NOTICE and OSHA’s rules

OSHA’s general sign rule names no notice sign. Its three classes are danger signs, caution signs and safety instruction signs, the last for “general instructions and suggestions relative to safety measures” and coloured white with a green panel. NOTICE signs come from the ANSI Z535 standards, which OSHA’s sign rules have accepted as an alternative since 2013.

Look-alikes

In the ISO 7010 system a white pictogram in a solid blue circle is a mandatory sign: it says that a specific action is to be taken, such as wearing eye protection. A blue NOTICE header on an American sign carries information about practices instead.
