  2. Colour-Coded System: UK health and safety signs utilize a colour-coded system to convey different levels of risk and importance:
    • Red: Indicates danger and potential for severe injury or death. Used for prohibition signs.

  2. Durable Materials: UK health and safety signs are made from durable materials such as rigid plastic, aluminum, or vinyl to withstand regular use and harsh environments. They are also often photoluminescent, meaning they glow in the dark, ensuring visibility in low-light conditions or power outages.

Placement and Maintenance

UK health and safety signs should be strategically placed at locations where they are most visible and relevant to the potential hazards or safety instructions. They should be mounted at a height that is easily seen by occupants, typically between 6 feet and 8 feet from the floor.

Routine cleaning and replacement of damaged or faded signs are essential to maintain their visibility and effectiveness.
