Joelma Building
The Joelma Building is a 25-story building in São Paulo, Brazil, located at 225 Avenida 9 de Julho. At 8:50am on 1 February 1974, an air conditioning unit on the twelfth floor overheated, starting a fire. There were 756 people in the building at the time. Because flammable materials had been used to furnish the interior, the entire building was engulfed in flames within 20 minutes. The fire was extinguished at 1:30pm, with 179 deaths and 300 people injured.
==Safety concerns==
The Joelma Building was a reinforced fire-resistant concrete hull construction.
The interior was furnished with flammable items. Partitions, desks and chairs were made of wood. The ceilings were cellulose fiber tiles set in wood strappings. The curtains and carpets were also flammable.
At the time, no emergency lights, posted in fire alarms, fire sprinkler systems, or emergency exits were fitted to the building. There was only one stairwell, which ran the full height of the building. An air conditioner unit on the twelfth floor, which started the fire, needed a special type of circuit breaker, which was unavailable at the time it was installed. In order to use this unit, it was installed bypassing the twelfth floor electrical control panel.
