ST. LOUIS (KPLR) – Firefighters and a HAZMAT crew responded to a fire on the Saint Louis University north campus.
The fire started around 6:30 p.m. on the third floor of Macelwane Hall, located in the 3500 block of Laclede Avenue.
The third floor is made up of office space and a neuroscience lab. No one was in the building at the time of the fire.
However, chemicals in the floor below that could pose a risk, so firefighters have taken added precautions.
Firefighters will have to undergo a decontamination process once the fire is extinguished.
The cause of the fire remains under investigation.
