What does the yellow and black color scheme indicate in OSHA signage?

The yellow and black color scheme in OSHA signage is specifically used to indicate caution. This color combination serves as a visual warning to alert individuals to potential hazards that require attention or care. For instance, signs with this color scheme may be displayed in areas where there is a risk of slips and falls, such as a wet floor, or in zones where machinery is present, indicating that one should proceed with care. The use of yellow is intended to attract attention and promote awareness of safety issues in the environment, making it clear that caution is necessary.

Other options do not apply to this color scheme. Emergency instructions typically use red to signify danger or immediate action, while green is often used for general safety information. Regulatory requirements are usually indicated with a blue color scheme, distinguishing them from cautionary messages.
