I understand what you say Lilly but these buidings are designed like most blocks of flats in the world. The principle is that the building should contain fires in the rooms where they start to give occupants time to escape. Believe it or not, often the safest place for people in flats not affected by the fire is inside their flat with the door closed. The problems arise when the safety measures are compromised - ie through neglect, poor workmanship, bad house-keeping, wedging open doors, breaches in the fire resisting structure through pipes and ducts not properly sealed. A similar fire in Birmingham a few years back that spread through the floors was made worst due to holes in the ceilings of the flats not being repaired properly. If the Council are to be implicated - and an enquiry would reveal this - then I wouldn't be surprised if it is through these kind of issues, and not because they didn't provide an alternative means of escape (which is practically very difficult in high rises)
