Health and safety signs are essential in any workplace, playing a crucial role in preventing accidents and ensuring employee well-being. These signs rely on specific colours to convey different types of information quickly and effectively. In this blog, we’ll dive into the four primary colours used in health and safety signs—red, yellow, blue, and green—and explain their meanings, examples of usage, and why it’s crucial to recognise them.
Red: Danger and Prohibition
Meaning: Red is the colour of danger, prohibition, and emergency situations. It’s designed to grab attention instantly, making it ideal for conveying critical safety information.
Examples of Use:
- Fire Equipment Signs: Red is often used for signs that identify fire-fighting equipment, such as fire extinguishers and fire hoses.
- Prohibition Signs: Common examples include a red circle with a diagonal line, indicating actions that are not permitted, such as "No Smoking" or "No Entry."
Importance: Recognizing red signs can be lifesaving. In emergencies, knowing the location of fire equipment and understanding prohibited actions can prevent accidents and save lives.
Yellow: Caution
Meaning: Yellow is used for cautionary signs, warning individuals about potential hazards and the need for careful attention.
Examples of Use:
- Warning Signs: These might include warnings about slippery floors, electrical hazards, or areas requiring caution, like construction zones.
- Hazard Signs: Signs warning of hazardous materials or conditions typically use yellow, often paired with black symbols or text.
Importance: Yellow signs help prevent accidents by making people aware of potential dangers. They serve as crucial reminders to proceed with caution and take appropriate safety measures.
Blue: Mandatory Actions
Meaning: Blue signs indicate mandatory instructions that must be followed to ensure safety.
Examples of Use:
- Safety Instructions: These include signs requiring the use of personal protective equipment (PPE), such as "Wear Hard Hats" or "Wear Safety Goggles."

Importance: Compliance with blue signs is essential for maintaining a safe work environment. These signs provide clear instructions that, when followed, help prevent injuries and accidents.
Green: Safe Conditions
Meaning: Green is associated with safe conditions, providing information on safety procedures and identifying safe locations and equipment.
Examples of Use:
