Firefighters are tackling a blaze at a large commercial building in Tiverton.
Emergency services were called to Tiverton Business Park this afternoon, where they found half a building "well alight".
Lisa Horforth captured this footage of smoke billowing from the scene:
Crews from Tiverton, Cullompton and Witheridge were originally mobilised - they called for assistance from another five trucks.
Fire fighters say that in a building measuring 100m by 40m over half the industrial units inside were well alight on arrival.
The Aerial Ladder Platform is also being used to tackle the fire.
Steady progress is being made containing the fire within compartment walls. Crews are now working internally checking for fire spread. They have also requested the attendance of a second Aerial Ladder Platform which was sent from Danes Castle.
