Grenfell Tower door could only hold back fire for 15 minutes

A door from Grenfell Tower could only hold back a fire for 15 minutes, half the time they had been designed to resist a blaze, a police investigation has found.

The Metropolitan Police said in a statement: ‘The Metropolitan Police Service is conducting a comprehensive investigation into what happened at Grenfell Tower in June last year. We have previously described that our forensic examination at the scene would be followed by a phase of offsite testing to be conducted by experts on our behalf.

‘As part of this investigation, experts tested a flat front door taken from Grenfell Tower. The door tested was designed to resist fire for 30 minutes, but during the test it was only found to resist the fire for approximately 15 minutes, a much shorter period than expected.

‘The forensic examination and testing phase is ongoing and we are not able to comment on the potential impact or otherwise that any test result may have on the overall criminal investigation.

‘We have shared this information with the Ministry of Housing, Communities and Local Government as the appropriate Government department, so that they are able to take any action required.’
