Fire engines from Devon and Somerset as well as Avon Fire and Rescue have responded to a 'large fire' at Bridgwater and Taunton College.
Residents who live nearby are being told to keep their windows shut, while emergency crews respond to the situation.
Avon and Somerset Police says it is supporting the fire services at the scene and is urging the public to avoid the area.
UPDATE: Following a fire service and police investigation, it has been confirmed that the fire was deliberate.
All single storey sections of the 80m by 60m building at College Way are involved in the fire, Devon and Somerset Fire and Rescue Service confirmed this morning.
The service said crews are 'containing the fire' and 'protecting fire spread to the other parts of the building'.
Local resident Chris Hutter alerted the emergency services to the fire after hearing bangs while watching TV, and says he felt it was his 'neighbourly duty' to respond.
He said: "I was watching TV as I couldn't sleep, at 3.30am this morning I heard light bangs I then looked out my bedroom window and saw white smoke and orange flames coming from the back of the college.
"I automatically dialled 999. The college is a less minute away from my house, and I directed the fire engines to where I saw the fire coming from.
"I was only doing my duty as my house backs on to the college. I would to thank all the emergency service for attending so quickly."
