31 March 2021

The Dangerous Goods Emergency Action Codes List 2021 is now available. The new list has again been produced by the NCEC, in co-operation with the UK Home Office and is published by TSO.


The EAC List 2021 is effective immediately in connection with the use of ADR/RID 2021 Edition and is mandatory from 1 July 2021 and the Emergency Action Code List 2019 should no longer be used from that date.

Duty holders are required to use the 2021 EAC List for the application of the appropriate EACs under Schedule 1 of the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (CDG 2009) (as amended); and of the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations (Northern Ireland) 2010 (CDG 2010) (as amended).
