One firefighter was injured Sunday as crews battled a large fire at a commercial building in Dudley, Massachusetts.

The Dudley Fire Department received numerous calls around 3:40 p.m. for a fire at Rampco Construction Company, located at 120 Schofield Avenue. Several additional communities sent firefighters to help at the scene.

There was a large volume of fire from the rear of the building on an open platform that houses storage for the construction company, according to fire officials.

The fire mostly stayed out of the main building and it was under control in one hour.

The only injury was a firefighter suffering from heat exhaustion, officials said.

There was no word yet on the cause. The state fire marshal’s office was responding to make that determination.

It’s rather poetic that meteorological summer ended Sunday — we’ve made it past moving day, college students are back on campus, and Boston Public Schools are about to be in session. We may be waving “goodbye” to summer, but not to free things to do in the area. This week, check out a civic-minded panel in Dorchester, and the return of the Boston Arts Festival. Plus, free admission to the Institute of Contemporary Art all day Labor Day.
