Wheatland County Fire Services responded to the fire at the Canadian Natural Resources Ltd. facility at 5:30 a.m.

The blaze was later declared under control.

Fire crews said the surrounding area was evacuated as a precaution.

There were no details about the condition of the second person injured.
