The hon. Lady is starting her speech in an excellent fashion and I congratulate her. The problem for me is that the COMAH site on Canvey Island will be a liquefied natural gas site, not a petrochemical site. With LNG, it is much more difficult to fight the fire. In fact, it is impossible, because it vaporises and floats as a cloud in the air until it meets an ignition source. We cannot use foam, as we can on a petrochemical fire, as happened at Buncefield, for example. Essex firefighters went in and fought that fire and many of those firefighters were trained to protect my constituency.
