A large fire broke out earlier, burning through a building on 14th Avenue and 40th Street, with flames continuing to burn as firefighters battled the blaze.

The FDNY transmitted a 10-75 for the fire at 4002 14th Avenue after flames broke out inside the three story building that housed various mechanical machines. Thick smoke and flames could be seen pouring out as fire crews rushed to get the situation under control.

The fire remained active and continued spreading through parts of the building as emergency crews operated on scene. The fire was then raised to a second alarm.

Hatzolah was on scene and treated one firefighter with serious injuries before transporting them to the hospital. 

Hazmat teams were also requested to the scene to investigate a reported suspicious substance found in the building.
