Buffalo firefighter dies while battling blaze
A firefighter died inside a burning commercial building in downtown Buffalo on Wednesday, where a fire and sudden blast sent flames and smoke billowing into the street.
Fire Commissioner William Renaldo said the fireball was likely caused by a backdraft, which he said occurs when oxygen is “sucked into the building and then blown back.”
The building held a theatrical costumes shop.
The firefighter’s identity was not immediately released.
The cause of the fire is under investigation. Renaldo said workers were using blowtorches on the building’s exterior before the fire and that heat may have transferred through brick or mortar to the interior and ignited paper or other combustibles.
