Grenfell Tower was built in 1974. It is suspected that this building did not meet the standard of protection from fire. The residents had expressed a worry about fire. But the administrating company might ignore their complaint.
It seems that the fire was immediately spread to the full range of the building. It means that normal precaution was not equipped in this building. Sadiq Khan, the Mayor of London, said that it was a preventable accident caused by years of neglect by the local council and successive governments. Theresa May, the Prime Minister, announced the necessity of the entire investigation.
