On June 16, 1925, Chicago Fire Department Captain William Sikora of Squad 2 died in the line of duty while rescuing trapped construction workers from an underground caisson chamber on West Jackson Boulevard. Firefighters responded to the scene after three workers in the chamber collapsed and lost consciousness due to leaking sewer gas. Sikora descended into the caisson chamber wearing a breathing apparatus, and successfully revived two construction workers who he sent to the surface. Sikora also recovered the body of one dead worker, but he collapsed from asphyxiation when his breathing apparatus ran out of oxygen before he himself could climb out of the caisson.
