A computer melted and the ensuing smoke caused crews to close down part of Bernard Avenue last night in downtown Kelowna.
Just before 1 a.m. emergency crews were called for the faint smell of smoke coming from the Sun FM building downtown near Pandosy and Bernard.
Platoon Captain Tim Light said without knowing exactly what was going on, the incident commander on the scene was ready for anything.
"It looked like it might turn into something, so the incident commander at the time had three trucks there and had everything ready to go," he said.
Light said firefighters knew which room the smoke was coming from and before they started squirting water everywhere, an engineer from Sun FM arrived and told them the room was full of computers.
It turned out one of the computers had actually melted, it was not immediately clear why.
Crews de-energized the equipment and the situation was largely over.
Otherwise the building was not damaged and no people were injured.
