CBC NEWS — Four people are recovering after being injured in a stubborn fire at Port Hawkesbury Paper in Point Tupper, N.S.

According to CBC News, two firefighters had to be rushed to hospital after working to put out a blaze that broke out in a wood chip silo Thursday night.

“They were taken to Antigonish and then they were transferred to Halifax. The indication was that there was exposure to CO2 [carbon dioxide],” said Port Hawkesbury Mayor Brenda Chisholm Beaton.

One of those firefighters has already been released from the hospital, while the other is expected to be released.

The other two people injured in the fire, work at the mill, according to a news release from Port Hawkesbury Paper. Both of those workers are now out of the hospital. Neither the company nor Unifor, the union that represents the workers, would say how the two employees were hurt.

The cause of the fire hasn’t been determined.
