FAQs

Multi-message signs come in a variety of materials to suit different environments.

These include:

  • Plastic - a cost-effective and lightweight option.
  • Metal - strong, long-lasting, and ideal for industrial settings.
  • Polycarbonate - tough, durable, and suitable for outdoor use.

Polycarbonate signs are especially popular for high-traffic or outdoor sites.

Multi-message signs combine several safety instructions or warnings into one sign.

For example, a sign may include:

  • Prohibitions - such as “No Smoking”
  • Mandatory instructions - such as “Wear PPE”
  • Warning symbols - such as “Forklifts Operating”

This reduces clutter, saves wall space, and makes safety information clearer to everyone on site.

Multi-message signs should be used in the range of places your risk assessment identifies.

These signs are especially useful in:

  • Factories - to cover equipment warnings and safety requirements
  • Construction sites - where multiple hazards exist in the same area
  • Warehouses - where vehicle, pedestrian, and PPE rules must be clear
