Fire crews responded to a working brush fire in the area of Upson and Covey Roads Saturday afternoon.
Tankers from Unionville and Burlington helped transport water. Tunxis and Harwinton tankers also responded.
A nearby public library was evacuated as firefighters fought to put out the flames.
"One of my coworkers got a call from someone in the fire department saying that we should evacuate the building. We closed up and went outside and watched them put it out and then we decided to re-open," said one librarian.
The fire spread for several miles, destroying 5 acres, said Deputy Chief Andrew Mercieri.
Fire officials said one firefighter suffered from smoke inhalation and was transported to Bristol hospital.
The cause of the fire is under investigation.
