On December 11 2006, it will be exactly a year since the UK experienced its largest explosion since WW2, when a series of blasts and fires broke out at the Buncefield oil depot in Hertfordshire.

How have those businesses implicated by Buncefield recovered, and what risk management lessons can all companies, wherever their geographical proximity, learn from the incident?
