HAZCHEM

OR

ADR

PANEL

Although the information and signs required by law may be carried on separate panels, it is most common accepted practice  for vehicles running under UK regulations to carry all the necessary details on a combined panel, usually referred to as the Hazchem (or ADR) Panel. 

This example shows a Hazchem Panel with Hazchem Emergency Action Code(EAC). The four-digit UN Substance Identification Number identifies the substance in transit.

Vehicles running under ADR (international) regulations display a similar orange board with a 3-digit ADR Kemler Code instead of an Emergency Action Code.  The UN number is beneath, as with UK transport. Vehicles running under ADR tend not to have integrated Hazchem boards, with the class diamonds (referred to as 'placards' in the ADR regulations) being displayed separately.  There is no requirement under ADR for an emergency telephone number.  This is felt to be a significant weakness when compared to the UK regulations.
