Hazard diamonds are offered in one standard size as required by IMO regulations. The 250mm square size should suit most applications however we are able to produce alternative sizes if required.

Hazard diamonds are printed on white self-adhesive vinyl and are suitable for all external marine applications provided they are applied to a clean, smooth surface.

Two styles are offered:

  1. Diamonds which include a class number.

  2. Diamonds which include a panel for the addition of a UN number.

With certain class 1 (explosive) hazard diamonds we require you to advise us of the hazard division and compatibility group numbers before we can proceed with supply. In the event of an order where this is un clear we will contact you for clarification.
