When will they ever learn, see below (also reminiscent of Cocoanut Grove in Boston; some exits in back may have been blocked by club owner who didn’t want people to leave without paying)
>>Reports say there was only one exit and panic spread as people tried to get out. Many victims reportedly died from inhaling toxic fumes.

It did have the capacity to hold such a crowd:
>>A reporter at the scene told local radio that the nightclub had a capacity for up to 2,000 people and was believed to be full on a Saturday night.
...but only one exit?
(the part about sim. to Cocoanut Grove refers to “only one exit”; the bit about “club owner had back exits locked” was Cocoanut Grove. Not sure about situation in Brazil. The Station fire had people panicking and using the same exit, mostly. Video of the Station fire shows how fast it spread but I think I read somewhere that they had about 2.5 to 3 minutes to get out of there, most likely via multiple exits—we’re talking 400 patrons though, but maybe after the first minute or so there was a big jam of panicked concertgoers and they got trampled a la the Who’s Cincy show...)
