Adapted from Huff Post World:
The tragedy of a deadly fire in a nightclub January 27th
continued to send shock waves through
Santa Maria, a college town of 260,000 people that was stunned by the
early Sunday morning tragedy in the Kiss nightclub.
The Rio Grande do Sul state forensics department raised the death toll
Tuesday from 231 to 234 to account for three victims who did not appear
on the original list of the dead. Authorities say more than 120 people
remain hospitalized for smoke inhalation and burns, with dozens of them
in critical condition.
The blaze began at around 2:30 am local time, during a performance by
Gurizada Fandangueira, a country music band that had made the use of
pyrotechnics a trademark of their shows.
Police have said the club's ceiling was covered with an insulating foam
made from a combustible material that appeared to have ignited after it
came in contact with a spark from a flare lit during the performance.
After the fire extinguisher malfunctioned, the blaze spread throughout
the packed club at lightning speed, emitting a thick, toxic smoke.
Because Kiss apparently had neither an alarm nor a sprinkler system and
only one working exit, the crowd was left to search desperately for a
way out.
The GCP event was suggested by several different people, one of whom
gave specifications: 6 hours beginning 30 minutes before the fire started.
News reports indicate that was 2:30 am, so the GCP event was set for
0200 to 0800 local time (UTC 04:00 to 10:00). The result is Chisquare
21521.840 on 21600 for p = 0.646 and Z = -0.373.
It is important to keep in mind that we have only a tiny
statistical effect, so that it is always hard to distinguish
signal from noise. This means that every "success" might be
largely driven by chance, and every "null" might include a real
signal overwhelmed by noise. In the long run, a real effect can
be identified only by patiently accumulating replications of
similar analyses.
