Two employees from Vale's Clarabelle Mill had to be rescued from the roof of the mill, but they were otherwise unharmed, said Greater Sudbury Fire Services Public Safety Officer Leo Frappier.
Although the cause is still being determined, it was a conveyor belt that caught fire, causing thick, black smoke, said Frappier. Damage is estimated at $2 million.
Firefighters responded to the call shortly after 9 a.m. At first, three stations responded to the call, but when they saw the smoke, the remaining two stations were called in, Frappier said.
In total, 30 firefighters responded.
When they arrived, employees were already being evacuated. In the course of ensuring the area was clear, firefighters noticed the two employees on the roof.
"The fire was very easy to contain," Frappier said. "It was made more difficult due to the thick, black smoke which means our firefighters had to wear their full breathing apparatus."
