What colors are mandated for safety posters?

Safety posters are primarily mandated to use red and yellow colors because these colors universally convey important warnings and safety information. Red is commonly associated with danger, emergency situations, or stop, making it highly visible and attention-grabbing. This color is effective in alerting individuals to hazardous conditions or critical safety guidelines that need immediate attention.

Yellow, on the other hand, is used to indicate caution. It signifies potential hazards that may require alertness or carefulness, such as slip and trip hazards. The combination of these two colors creates a strong visual cue that effectively communicates urgency and the need for safety awareness to all individuals in a workspace or public area.

The other colors listed do not adequately fulfill the same safety messaging role as red and yellow. Green typically indicates safety or permission, while black and white are often used for informational purposes but lack the immediate attention-grabbing qualities needed in safety signage. Yellow and green could be misleading as they can denote different levels of caution without adhering to standardized safety signaling practices.
