Nearly 10 fire departments responded to a report of a fire at Lovell Federal Health Care Center in North Chicago Wednesday morning, officials said.

The Great Lakes Fire and Emergency Services responded around 7 a.m. Wednesday to a fire alarm at Captain James A. Lovell Federal Health Care Center, 3001 Green Bay Road in North Chicago.

Lovell Federal Health Care Center is a hospital that provides medical care for active duty military, their family members, military retirees and veterans.

Fire crews attempted to locate the source of smoke inside the building, a spokesperson for Great Lakes Naval Station said.

Eventually, the incident was upgraded through the Mutual Aid Box Alarm System (MABAS), which prompted the response of multiple Lake County fire departments.

Those departments included Waukegan, Grayslake, Gurnee, Lake Forest, Lake Bluff, Libertyville, Beach Park and North Chicago.

The Highland Park, Winthrop Harbor and Deerfield fire departments covered calls on Great Lakes Naval Base.

It was eventually determined a mulch fire near the building caused smoke to get into the building, which set the fire alarm off, the spokesperson said.

Firefighters were on the scene for several hours Wednesday morning. No one was injured in the incident.
