3 Injured in Flash Fire at Electrical Substation in Chicago's Loop: CFD

Three people were injured in a flash fire at an electrical substation in Chicago's Loop Tuesday that left hundreds of people in the area without power, fire officials said.

The fire took place at substation near the intersection of North State Street and East Lake Street, according to the Chicago Fire Department.

An arc flash, a type of electrical explosion, relayed to a transformer, sparking the blaze around 12 p.m., authorities said.

At least three people working in the building were injured in the incident, officials said. Two people were taken to Northwestern Memorial Hospital, while another was being evaluated and might be transported, according to CFD. Information on the victims, including their conditions, was not available.

CFD spokesman Larry Langford said the fire took place at a Chicago Transit Authority substation powered by ComEd. ComEd said the incident caused an issue with a circuit breaker, leaving around 500 customers in the area without power. Crews were working to restore power, a spokesman for ComEd said Tuesday afternoon.

The CTA did not immediately respond to request for comment.

The fire was struck out and the building secured by 1 p.m., authorities said.

CTA buses on route #29 and southbound on routes #6 and #62 were temporarily rerouted, the agency tweeted, as emergency personnel remained on the scene. 

Further details were not immediately available as authorities continue to investigate.
