A Thursday afternoon fire at LSU’s Huey P. Long Fieldhouse on Field House Drive caused the evacuation of a handful of students, faculty and staff from the building, but did not injure anyone, Baton Rouge Fire Department investigators said.

A preliminary investigation pointed to a blow torch used during some construction work as the source of the early afternoon blaze that began in parts of the wall and ceiling near the back of the building’s first floor, said Robert Combs, a Baton Rouge Fire Department spokesman.

It was not immediately clear how many people were inside the building when the fire began shortly after 2 p.m., Combs said, but all the occupants of the building were evacuated safely.

East Baton Rouge Parish Emergency Medical Services respondents did examine one student for possible injuries, but he was not treated for any injuries, Combs said.

The fire produced lots of smoke, Combs said, but it wasn’t immediately clear how much damage was done to the historical building.

The fire was under control by 3:15 p.m., Combs said, and investigators are on scene to determine the official cause of the fire.
