Brazil nightclub owner blames country for fire Associated Press Copyright 2013 Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed. Updated 4:00 pm, Wednesday, January 30, 2013 Police investigating the blaze have said it likely started when a country music band performing at the Kiss nightclub in the college town of Santa Maria lit a flare, which ignited flammable soundproofing foam on the ceiling. Marques insisted in a phone interview with The Associated Press that "my client's responsibility is having trusted too much in the inspectors and in those responsible for the construction." The number of injured jumped to 143 Wednesday after 22 people were admitted to hospitals with respiratory problems after having escaped the club apparently unharmed. Brazil Health Minister Alexandre Padilha has urged the fire's survivors to remain alert for any symptoms of so-called "chemical pneumonia," which can take up to three days to develop following exposure to toxic fumes and smoke. The tragedy raised questions about the reliability of safety regulations in a nation set to host the World Cup and Olympic Games. Documents obtained by The Associated Press, including past building and fire safety plan permits issued to the club, showed that the single exit, the foam insulation and other contributors to the tragedy didn't violate laws. The same documents show that other regulations were broken, including irregularities in the fire safety inspection of the club, as well as pyrotechnics used by the band that police say should not have been set off indoors. Elsewhere, the government of the country's biggest city, Sao Paulo, set to host the opening match of the 2014 World Cup, promised tougher security regulations for nightclubs. The fire even sparked action in the Central American country of Nicaragua, which is banning the use of fireworks or other incendiary devices in nightclubs and other enclosed spaces, police spokesman Francisco Diaz said Wednesday.
