FIREFIGHTERS are working to extinguish a small fire at the National Gallery on Bowen Drive in Barton.
The building has been evacuated.
UPDATE: 4.24pm
FIREFIGHTERS are currently cutting open the ducting to ensure the fire is fully extinguished.
The fire, which started because of a build-up of saw dust in a machine at the back of the gallery, is not-suspicious.
ACT Fire & Rescue is conducting atmospheric monitoring to ensure the area is safe and will shortly allow people back into the building.
Crews will remain on scene for about another hour.
