Introduction
The Carriage of Dangerous Goods and Use of
Transportable Pressure Equipment Regulations 2009 (CDG 2009)
and the European agreement ADR which together regulate the
carriage of dangerous goods by road are highly prescriptive.
The regulations were substantially restructured for 2009 with
direct referencing to ADR for the main duties. CDG 2009 now
cross-refers almost totally to ADR, and it is ADR that contains
the detailed requirements. I am not an expert in this field
and this legislation is very complicated, the following are
simple images of the signs (Labels) used however treat all
the information with caution.

PLACARDS AND PLATE MARKINGS FOR NATIONAL
CARRIAGE
United Kingdom Tankers (Road)


Continental Tankers (Road)

A plate known
as a orange-coloured plate and displayed on vehicles and containers
carrying hazardous loads is now
included in the latest regulations (CDG 2009) It is designed
to help the emergency services to deal with incidents involving
such vehicles or containers.
The UK orange-coloured
plate has more information than the continental plate
and the first panel (1), which provides instant information
for responding emergency crews, uses a different code than
the continental plate. The UK uses a Emergency Action Code
also known as Hazchem
Code and the continental panel (1) uses a Hazard
Identification Number also known as the Kemler
Code. The both use the same system in the second panel
(2) which is the UN Substance Identification Number.
