The world's deadliest tower block fires

A retired judge, Sir Martin Moore-Bick, has been appointed to head the official inquiry into London’s Grenfell Tower fire in which at least 79 people died, while the police say they are investigating any criminal offences that may have been committed.

The deadliest ever fire in a tower block (or blocks) was the result of the terrorist attack on New York’s World Trade Centre on 11 September 2001, which cost more than 2,300 lives, but the worst accidental fire was probably the one that raged through the 25-storey Joelma office building in Sao Paulo, Brazil on 1 February 1974. (Grenfell Tower had 24 storeys.)

The blaze happened just a few weeks after the disaster movie, The Towering Inferno, was released, and it became known as ‘the real Towering Inferno’. It was started by an electrical fault on the 11^th floor, and spread rapidly thanks to the ready availability of combustible materials such as paper, plastics and wooden walls and furniture.

When the blaze began, there were more than 750 people in the building. More than 170 fled to the roof, but the heat and smoke foiled a helicopter rescue, and about 40 were killed jumping down or trying to get to firemen’s ladders out of reach below them. Altogether up to 189 people died. 

The real 'Towering Inferno'

On this day…..42 years ago, fire broke out in the 25-storey Joelma Building in the centre of Sao Paulo in Brazil. The blaze happened just a few weeks after the disaster movie, The Towering Inferno, was released, and it became known as ‘the real Towering Inferno’.

The fire was started by an electrical fault on the 11^th floor, and spread rapidly thanks to the ready availability of combustible materials such as paper, plastics and wooden walls and furniture, and within a few minutes, flames were leaping right up to the roof.

When the blaze began, there were more than 750 people inside, but the building had no emergency exits, fire alarms or sprinkler systems. More than 170 fled to the roof, but the heat and smoke foiled a helicopter rescue, and about 40 were killed jumping down or trying to get to firemen’s ladders out of reach below them.

Others died of suffocation attempting to escape via the building’s escalators, and altogether up to 189 people were killed. After the disaster, Brazil’s fire regulations were tightened up.
