What safety hazards is the color yellow used to signify?

The use of the color yellow in safety signage is widely recognized as an indication of caution, particularly in environments where there are potential hazards that require attention. Yellow is often used to signify walkways and areas where trip hazards may exist. This color alerts individuals to exercise care and avoid accidents, helping to prevent falls or injuries in locations that may not be immediately obvious as dangerous but still pose a risk.

In various settings, including industrial and educational environments, yellow markings are commonly used to delineate safe paths or to highlight areas where one should be cautious, such as around obstacles or uneven surfaces. This practice is based on established safety protocols that aim to guide individuals in navigating their environments safely.

While the other color applications listed serve important safety purposes as well, such as indicating emergency exits (often marked with green) or fire safety equipment (often marked with red), the specific association of yellow with caution in terms of walkways and potential trip hazards is a fundamental aspect of safety training and awareness.
