Fire Prevention Day takes place on October 09, 2020. It commemorates the Great Chicago Fire. The Great Chicago Fire was a conflagration that burned from October 8, to early October 10, 1871, killing hundreds and destroying about 3.3 square miles (9 km²) in Chicago, Illinois.
The traditional account of the origin of the fire is that it was started by a cow kicking over a lantern in the barn owned by Patrick and Catherine O'Leary. In 1893, Michael Ahern, the Chicago Republican reporter who wrote the O'Leary account, admitted he had made it up as colorful copy. The barn was the first building to be consumed by the fire, but the official report could not determine the exact cause.
On the 40th anniversary (1911) of the Great Chicago Fire, the Fire Marshals Association of North America (FMANA); the oldest membership section of the National Fire Protection Association (NFPA), sponsored the first National Fire Prevention Day, deciding to observe the anniversary as a way to keep the public informed about the importance of fire prevention.
In May 1919, when the NFPA held its 23rd annual meeting in Ottawa at the invitation of the Dominion Fire Prevention Association (DFPA), the NFPA and DFPA both passed resolutions urging governments in the United States and Canada to support the campaign for a common Fire Prevention Day.
