CHICAGO -- Four firefighters were injured in a fire that required a Mayday alarm Sunday on the West Side.

All are in stable condition, according to a tweet from the fire department.

The Chicago Fire Department sent out a Mayday alarm during a fire at a residential building on the 4900 block of W. Potomac Ave. At one point the heat and fire surged, forcing firefighters to retreat. The crews tracked the source near a kitchen on the second floor. When they entered that area, the flames intensified.

The blaze was extinguished around 12:30 p.m., according to the Chicago Fire Department.

An EMS Plan I which automatically sends at least six ambulances to the scene was initiated. The firefighters were transported to Stroger Hospital. One is a man in his 30s, another in his 40s, and two in their 50s.

The blaze displaced six people.
