SANTA MARIA, Brazil — There was no fire alarm. There were no sprinklers or fire escapes. And when a band member tried to put out a fire that had been started by pyrotechnics, the extinguisher didn’t work.

All the elements were in place for the tragedy at the Kiss nightclub early Sunday. The result was the world’s worst fire of its kind in more than a decade, with more than 230 people dead and this southern Brazilian college town in mourning.
