What color is used to indicate caution in safety signage?

The use of yellow to indicate caution in safety signage is based on widely accepted color-coding conventions in safety practices. Yellow is a bright, attention-grabbing color that signifies the need for alertness and caution, encouraging individuals to proceed with care. This is crucial in environments where there may be potential hazards, such as slippery floors, overhead loads, or machinery in operation, ensuring that individuals are aware of their surroundings and can take appropriate actions to avoid accidents.

In contrast, red typically denotes danger or stop, signaling that immediate action is required, such as in fire alarms or stop signs. Green is often used to indicate safety or permission, such as in exit signs, while blue can signal information or mandatory instructions. Therefore, using yellow in safety signage effectively communicates a message of caution, making it easier for individuals to recognize and respond to potential hazards in their environment.
