Dangerous Goods Diamonds


DG Diamonds are designed to tell people that certain classes of hazardous substance or dangerous goods are present.  For example, a flammable liquid diamond lets people know that flammable liquids are:

  • On this site (if displayed at the entrance or gate)
  • In this building (if displayed on the outside of the building)
  • In this hazardous substance area (if displayed in a specified area)
  • In this tank (if displayed on the outside of a bulk tank)
  • In this container (if on the label of a product)
  • In this vehicle (if displayed on a vehicle placard)

Hazardous Substance or Dangerous Goods Diamonds can differ slightly depending on whether they are to be used for storage and product labelling, or if they are to be used in transport.  For example, the class 4.3 Spontaneously Combustible diamonds have black writing and flame when used for storage, but white writing and flame if used for transport.

All our DG Diamonds come in a range of sizes:

  • 100 x 100 – good side for product and packaging labels
  • 250 x 250 – minimum size of DG Cabinets and building signage
  • 295 x 295 – larger size more visible for gate and building signage
  • 400 x 400 – Required size for transport tankers and tank wagons

All diamonds are available in three materials:

  1. PVC – Plastic (2mm width)
  2. ACM – Aluminum Composite Material (3mm width)
  3. SAV – Self Adhesive Vinyl Sticker
