Dear Mr Gardner
Vehicle Diamond Labels
The provisions in ADR regarding vehicle marking are to be found in Annex A, Part 5,
Chapter 5.3. The relevant paragraph dealing with marking is 5.3.2 and the applicable
sub paragraph is 5.3.2.1.1. This requires vehicles carrying dangerous goods to have
an orange plate mark fixed at the front and the rear of them. There are other
provisions regarding additional information and further orange plate marks but these
are not relevant to vehicles carrying packaged dangerous goods. The gas cylinders
mentioned in the enquiry are packaged dangerous goods.
In addition to the orange plate mark there are requirements to placard vehicles.
Placards are the same as the hazard diamonds except that they measure 250 x
250mm. Paragraph 5.3.1.5 deals with placards on vehicles carrying packages. Apart
from classes 1 and 7 placards are not required.
The requirement to fix orange plate marks to a vehicle is further modified an
exemption related to the quantities carried per transport unit. The detail is found in
paragraph 1.1.3.6 of ADR. The key elements to note here are that this exemption
only relates to packaged dangerous goods and that the limits for application of the
exemption vary according to the class, packing group and in some cases the UN
number of the goods being carried. ADR doesn’t formally recognise Class 2.2 but
note 1 after 2.2.2.1.3 identifies gases in groups A and O as belonging to that UN
group.
Gases in groups A and O have an exemption limit of 1000 litres (if the gas is
liquefied) or 1000 litres of water capacity of cylinders (if gaseous), and this can be
found in the table 1.1.3.6.3. The dis-applications for loads up to this limit are listed in
1.1.3.6.2. and include the whole of chapter 5.3. The orange plate mark is therefore
not required and since chapter 5.3 is the only place in ADR dealing with vehicle
marking the result is no vehicle marking or placarding is required. There is though the
possibility of a warning notice as the exemption doesn’t cover CV36 of 7.5.11 but this
is dependant on the type of vehicle used and its construction.
The 100 x 100mm labels referred to in the correspondence are to be found in
Chapter 5.2 of ADR. This chapter deals with the marking of packages and each
Ext
package of dangerous goods being transported shall have the labels listed in the
dangerous goods list affixed to it. This provision is not altered by the limited load
provision.
You will realise from above that ambulances with package labels on them are
needlessly marked particularly as emergency transport is exempt from ADR
completely.
In conclusion a vehicle carrying packaged dangerous goods below the thresholds
established in ADR at 1.1.3.6.3 requires no marks, labels or placards (but may
require a ventilation warning). The vehicle must be fitted with a 2 kg dry powder (or
equivalent) fire extinguisher for flammability classes A B and C, and the driver should
have had some general awareness training commensurate with his responsibilities.
Vehicles with packaged dangerous goods over the threshold will have orange plates
front and rear. In addition ADR applies in full and this will increase the number and
size of the fire extinguishers, require an ADR trained driver, Instructions in writing and
the appropriate kit for the crew, and a company DGSA amongst other things.
