French authorities have released a statement stating why Notre Dame fire was hard to put out, by the Fire Fighters and other agencies deployed to the scene, . The centuries-old wooden roof beams, stone exterior and soaring Gothic architecture made Monday’s blaze especially difficult to tackle and Paris firefighters deserve praise for their efforts, experts say, CNN reports.
The spire and most of the roof of the centuries old cathedral have been destroyed, but the two bell towers and the main edifice were saved. Video released by the French Interior Ministry showed the scale of the response. Authorities deployed some 400 firefighters, pumped water from the Seine and flew drones to survey the damage.
The biggest problem, experts say, was accessing the wooden ceiling beams which formed the frame for the soaring roof.
“It was pretty evident in the first 20 minutes that it was going to be a bad fire,” said Gregg Favre, a former firefighter with the St. Louis Fire Department in the United States.
The fire fighters would have been at a disadvantage “before they ever even pulled out of the firehouse,” added Favre.
Once the beams start burning, the stone exterior makes it harder for firefighters outside the building to get to the source of the flames. The stone traps heat and smoke, preventing them from working inside.
The Notre Dame’s height also posed a challenge, providing extra oxygen for the fire to breath and complicating efforts to reach the flames.
“The fuel load is way up in the air, and the firefighters can’t get to it quickly,” said Glenn Corbett, associate professor of fire science at New York’s John Jay College of Criminal Justice.
Aerial options like the one suggested by US President Donald Trump were also considered unrealistic.
“Perhaps flying water tankers could be used to put it out. Must act quickly!” Trump said in a tweet.
Corbett also ruled out the use of helicopters:
“One of the issues you’ve got here, is that thermal updraft, that’s a chimney effectively, you can’t fly a helicopter in hot air. The air is so thin.”
