The Hopkinton Fire Department’s annual Open House is Sunday, Oct. 6. The event, held at the HFD headquarters on Main Street, will run from 10 a.m. until 1 p.m. Residents — especially children — will have the opportunity to view demonstrations, learn about fire safety and tour the station. Refreshments will be provided, and Sparky the Fire Dog is expected to make an appearance. The Open House provides an opportunity for firefighters to focus on the educational theme of Fire Prevention Week. This year’s theme is Smoke alarms: Make them work for you!
