Which color code is used for caution regarding physical hazards in safety equipment?

The color code used for caution regarding physical hazards is yellow. In safety equipment and signage, yellow is typically employed to signal a warning for potential hazards that require caution. This includes areas where there may be slip and trip hazards, equipment that could cause physical injury, or other safety concerns that individuals should be aware of in order to avoid accidents.

Red is generally used for fire-related hazards or to indicate stop conditions, while green typically signifies safety or an all-clear status. Blue is often used to denote informational signs and communication rather than warnings or hazards. Thus, yellow serves a vital role in alerting individuals to take care and be mindful of their environment, making it the appropriate choice for identifying physical hazards.
