Buncefield Oil Depot Fire

My hon. Friend has served his constituents with great assiduity. I am sure that this will not be the last time that he brings this matter before the House. Does my hon. Friend acknowledge the great efforts and skill of the Essex fire service, which featured in the incident? Is he aware that its firemen got their skills because of the Canvey Island calor gas importation site, the first such site for liquefied natural gas in the world? It now takes liquefied petroleum gas from ships in the Thames and there is a proposal to change it so that it can take a full 5 per cent. of the nation’s total energy need in LNG across Canvey Island. As everyone here will understand, that is raising local fears. We must learn any possible lessons from the Buncefield fire. Will my hon. Friend explain later why the early detection systems at Buncefield failed to warn of the developing clouds of vapour that had been rolling around for 20 or 30 minutes prior to the explosion? That is a key point.
