Bangor firefighters train on a controlled burn Sunday on a vacant apartment building on Main Street. Crews practiced on several fires set in different sections of the building, allowing firefighters to train for a variety of situations, including venting roofs, tearing down and breaching walls, and conducting search and rescue operations. The structure eventually was set on fire again and allowed to burn slowly. The neighboring structure, which once housed a bridal store, will be razed, Assistant Fire Chief Darrell Cyr said in a previous Bangor Daily News article. The properties at 440-460 Main St. must be removed from the site to make way for a Tim Hortons coffee shop and restaurant.
