Site Of Deadliest School Fire In U.S. History Gets New Sprinkler System

CHICAGO (CBS) -- A piece of Chicago and U.S. history receives a new sprinkler system.

Our Lady of Angels caught fire on December 1, 1958. Three nuns and 92 children died in that fire, making it the worst school fire in American history.

On Wednesday, groups will meet to celebrate the installation of a new sprinkler system. Several local unions paid for, retrofitted and installed the new system.
