• OSHA has numerous labeling requirements in its regulations, while ANSI has a non-mandatory product labeling standard.

ANSI standard

American National Standards Institute (ANSI) Z535.4-2017, American National Standard for Product Safety Signs and Labels, offers non-mandatory guidance for design, use, and placement of safety labels on products. These labels communicate hazards, instructions, consequences of ignoring the hazards or instructions, and other information.

The standard covers the following:

• Signal words (DANGER, WARNING, CAUTION, NOTICE, and SAFETY INSTRUCTIONS);
• Label format and color schemes; and
• Label placement, maintenance, and replacement.
