When to Use a Caution Sign in Your Workplace

OSHA's sign regulation, 29 CFR 1910.145, requires caution signs to warn against potential hazards or to caution against unsafe practices.

Typical applications include:

• Hot surfaces on machinery, piping and process equipment
• Slippery floors, wet areas and uneven walking surfaces
• Pinch points, low overhead areas and doorways
• Reminders to follow safe work practices and wear required PPE

Caution signs use a safety yellow background with a black panel and lettering, the color combination specified by 29 CFR 1910.145 and ANSI Z535.1 for this level of hazard severity.

Caution vs. Warning vs. Danger Signs: Choosing the Right Signal Word

Signal word selection is a severity decision. Under the ANSI Z535 standards, CAUTION identifies hazards that could result in minor or moderate injury. When a hazard could result in death or serious injury, a warning sign is the correct choice, and when the hazard will result in death or serious injury if not avoided, a danger sign is required. Messages that are important but not related to personal injury belong on a notice sign. For a deeper look at how the standard defines each level, see our resource on best practice safety signs with ANSI Z535.2.

Frequently Asked Questions About Caution Signs

What does a caution sign mean?

A caution sign indicates a hazardous situation that, if not avoided, could result in minor or moderate injury. This definition comes from the ANSI Z535 standards, which OSHA recognizes for workplace safety sign design.

What color are OSHA caution signs?

Caution signs have a yellow background with a black panel and yellow lettering for the signal word, with black lettering used for the message. These color requirements are set by 29 CFR 1910.145 and ANSI Z535.1.

When should I use a caution sign instead of a warning sign?

Use a caution sign when the worst credible outcome of the hazard is minor or moderate injury. If the hazard could result in death or serious injury, use a warning sign. Matching the signal word to the severity of the hazard keeps your sign system credible and defensible.
