The hazmat team found ammonia levels as high as 300 parts per million, which CFD Battalion Chief Innes Fraser said was high but not fatal.
Ammonia was being used as a coolant in the plant, according to the CFD.
Forty to 50 employees left the building before crews arrived, and a Calgary Transit bus was called in to shelter them, Fraser said.
There were no injuries, the CFD said.
