75 high-rise buildings fail fire safety tests after Grenfell disaster

Seventy-five high-rise blocks across 26 local authorities have failed fire safety tests since the Grenfell Tower disaster.

Checks are being carried out on hundreds of tower blocks after it was established that the cladding on the 26-storey building helped the fire, which is believed to have killed at least 79 people, to spread.

Communities minister Sajid Javid told the Commons that the so-called combustibility test had been failed by every building examined so far.

"The fact that all samples so far have failed underlines the value of the testing programme and the vital importance of submitting samples urgently," he said.

"I am concerned about the speed at which samples are being submitted.

"I would urge all landlords to submit their samples immediately."

Mr Javid also said that more than 1,000 fire doors were missing from four Camden tower blocks evacuated after fire safety checks.

"When the commissioners went into those tower blocks in Camden, in their own words, they found multiple fire safety inspection failures, failures which frankly should not have happened in tower blocks of any type, certainly those tower blocks in Camden," he told MPs.

"For example there were problems with gas pipe insulation, there were stairways that were not accessible, there were breaches of internal walls and most astonishingly there were hundreds, literally hundreds, of fire doors missing."

Schools and hospitals will also be tested to make sure their cladding is not combustible, Downing Street said earlier.

The latest update on the number of buildings on which the flammable cladding was used came as the US supplier of the covering said it was stopping sales for high-rise buildings.

"Arconic is discontinuing global sales of Reynobond PE for use in high-rise applications," a company spokesman said.

The firm put the decision down to "issues that have arisen in the wake of the Grenfell Tower tragedy" and differences in building regulations around the world.

Labour has called for a "triple fire safety lock" to guarantee the standards of buildings.

Shadow housing secretary John Healey said such a guarantee would include materials being fit for purpose and meeting safety specifications, plus regular fire risk assessments.

Meanwhile, Westminster coroner Dr Fiona Wilcox opened and adjourned the inquests into the deaths of four people in Grenfell Tower.

The inquest heard five-year-old Isaac Paulos choked to death on fumes from the fire and had to be identified by his dental records

He lived on the 18th floor, but his body was found on the 13th. He had disappeared as his family attempted to escape the flames.

The other three victims whose inquests were opened included artist Khadija Saye, 24; her mother, Mary Ajaoi Augustus Mendy; and Mohamednur Tuccu, 44.

All three were also recorded as inhaling fumes.
