Three-alarm fire on SLU campus

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.
