Vehicle Requirements

The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (CDG 2009) and the European agreement (“Accord européen relatif au transport international des marchandises dangereuses par route”, known as ADR) which together regulate the carriage of dangerous goods by road are highly prescriptive.

This page of the site deals with a brief overview of the equipment required for Road Vehicles.

Fire Fighting Equipment
ADR para 8.1.4 concerns fire extinguishers. The table below sets out a summary of the minimum requirements. Note that dry powder extinguishers are specified because it is known that they are suitable for tackling fires of class A (solids such as wood, paper etc), class B (fires involving liquids) and class C (fires involving gases).

The capacity of the fire extinguisher(s) required under (a) may be deducted from the minimum total capacity of the extinguishers required under (b). Transport units carrying dangerous goods at or below specified total quantities in accordance with ADR shall be equipped with one portable fire extinguisher for the inflammability classes 1 A, B and C, with a minimum capacity of 2 kg dry powder (or an equivalent capacity for any other suitable extinguishing agent).

See below for a summary of the above in a table format:

Vehicle Minimum dry powder fire extinguisher provision
Up to 3.5 t 2 kg for cab
plus 2 kg
Over 3.5 t and up to 7.5 t 2 kg for cab
Total 8 kg (usually one 6 kg but other provision is acceptable as long as there is one 6 kg)
Over 7.5 t 2 kg for cab
Total 12 kg (including at least one 6 kg)
Any vehicle carrying dangerous goods under the 'small load' limit or carrying only infectious substances One 2 kg only

If the vehicle is equipped with a fixed fire extinguisher, automatic or easily brought into action for fighting a fire in the engine, the portable extinguisher need not be suitable for fighting a fire in the engine. The extinguishing agents shall be such that they are not liable to release toxic gases into the driver’s cab or under the influence of the heat of the fire. The portable fire extinguishers conforming to the provisions of or shall be fitted with a seal verifying that they have not been used.

The fire extinguishers shall be subjected to periodic inspections in accordance with authorised national standards in order to guarantee their functional safety. The fire extinguishers shall be installed on the transport units in a way that they are easily accessible to the vehicle crew. The installation shall be carried out in such a way that the fire extinguishers shall be protected against effects of the weather so that their operational safety is not affected.

Electrical Equipment -
Special requirements in respect of wiring, batteries and lighting apply to certain road tanker vehicles and Type III vehicles used for the carraige of explosives.

Braking Equipment
Certain vehicles and trailers must be equipped with anti-lock braking devices and endurance braking systems. These provisions apply to motor vehicles exceeding 16 tonnes maximum permissible weight and trailers exceeding 10 tonnes maximum permissible weight which comprise the following vehicle categories:

Miscellaneous Equipment
Para 8.1.5 ADR refers to 'miscellaneous equipment'. The most common problem is in the wording of subparagraph (a) about wheel chocks. Under ADR, the transport unit has to carry at least one suitable chock for each vehicle (which means at least two chocks for articulated lorries and drawbar combinations). However, authorisation 24 permits GB registered 'transport units' on domestic journeys to carry one suitable wheel chock, even if there are two vehicles forming the unit. There is no prescription as to where wheel chocks are to be carried.

Other items which fall under this heading include:

Nature of load (by danger label) Equipment
Labels 3 - 9 Eye rinsing liquid
Labels 2.3 and 6.1 Emergency escape mask
Labels 3, 4.1, 4.3, 8, 9 1) Drain seal, 2) Shovel, 3) Plastic collecting container
