Pacific Western Brewery was evacuated and Prince George Fire Rescue was called in to deal with an ammonia leak on Thursday afternoon.
PGFR deputy chief Cliff Warner said the leak erupted when a valve was hit and cracked. He said the leak was isolated to an enclosed room and firefighters were to go in to try to further contain the damaged equipment and ventilate the building.
Firefighters were called in at about 12:15 p.m. and were on the scene for most of the afternoon.
