In
United States safety standards,
precautionary statements are sentences providing information on potential
hazards, and proper procedures. They are used in situations from
consumer product on labels and manuals, to descriptions of physical activities. Various methods are used to bring focus to them, such as setting apart from normal text, graphic icons, changes in text's font and color. Texts will often clarify the types of statements and their meanings within the text. Common precautionary statements are described below. See
ANSI 535.
