The fire originated in the basement near the foot of a stairway. The elementary school was operated by the Archdiocese of Chicago and had an enrollment of approximately 1600 students. A total of 92 pupils and 3 nuns ultimately died when smoke, heat, fire, and toxic gases cut off their normal means of egress through corridors and stairways.

A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane. In industrial explosions many other gases, like hydrogen, as well as evaporated (gaseous) gasoline or ethanol play an important role. Industrial gas explosions can be prevented with the use of intrinsic safety barriers to prevent ignition, or use of alternative energy.
