Large scale fire in a magnesium factory triggered explosions

A large fire broke out late Wednesday night March 5, 2025, at a magnesium manufacturing plant in Blue Island, in the outskirts of Illinois, causing explosions, and a hazardous materials response.

Fire crews were called to the facility according to Jeff Cook of the Posen Fire Department. Upon arrival, firefighters encountered intense fire through the roof. The location of the fire at the rear of the building, near railroad tracks, complicated access for emergency responders.

The presence of magnesium—a combustible metal—made the response more difficult, leading to multiple explosions inside the structure. Hazmat teams were dispatched to the scene to address the hazardous material concerns. Despite the severity of the fire, officials confirmed that no injuries were reported, and no one was inside the building at the time.

Cook described the building as a "total loss" but noted that the fire had been "mostly contained" by early Thursday morning. 

Fire crews continued working to ensure the flames were fully extinguished. Media reports have said explosions were still heard early in the morning hours.
