Eight people were hurt after an explosion and fire caused devastation at an industrial estate in Surrey. Of the eight who received injuries, two are thought to have sustained serious burns. One of them was airlifted to a London hospital, while the others were taken to nearby hospitals. One witness Natalie Dugdale told Sky News she heard three explosions and could see "masses and masses of smoke". She said fire officers told her the blast was caused by recycled printer toner.
