Regulation 6 of the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (CDG, as amended, or CDG 2010 in Northern Ireland) requires an Emergency Action Code (EAC) to be displayed on domestic road and rail bulk and tank transport vehicles carrying dangerous goods (known as transport units under ADR).

The full details are set out in Schedule 1 to the CDG Regulations.


Schedule 1 of CDG sets out the requirements for “hazard warning panels” to be used for UK domestic journeys in replacement to the orange coloured side plate marking provisions of ADR 5.3.2.

For domestic road journeys, the Hazard Identification Number (HIN) as required by ADR is replaced with the Emergency Action Code on each hazard warning panel, also known as hazchem boards.

The hazchem board is also required to be displayed at the back of a bulk or tank vehicle and an emergency telephone number must be displayed at the rear of a tank vehicle and on both sides of each tank.

Please see CDG Schedule 1, Part 1, § 3 and 4 for the full additional requirements that apply to road transport units carrying more than one type of dangerous goods in a tank or bulk.

The 2015 revision of the Emergency Action Code List is required to be used from 1st July 2015.

Copies of the EAC List 2015 can be downloaded from the NCEC

Further details of the marking requirements of UK domestic transport units carrying dangerous goods can be found on the HSE Website. Here you will also find easy to follow diagrams of the plating and placarding requirements.
