Blue signifies that an action is required, such as wearing PPE or following authorised procedures. Its use in mandatory signs ensures that workers understand the steps they need to take to stay safe.

Safe Areas & Directions

Green is the colour of safety and guidance. It’s used for emergency exits, first aid stations, and safe zones, giving people reassurance and clear direction during emergencies.

Warning & Caution

Yellow alerts people to potential hazards. Its bright, attention-grabbing hue makes it ideal for warning signs, such as those for slippery floors or construction zones. Yellow reminds people to be aware and proceed with care.
