These signs are intended to indicate potential, type, and degree of the hazard that may lead to accidental injury or property damage. Signs define specific hazards by conveying a clear, easily understood message. The sign headers and colors used in accident prevention safety signs are specified by OSHA and ANSI to designate the severity of the hazard. Each color has a specific role.
CAUTION (yellow): Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
