At least 6 firefighters suffered smoke inhalation as they battled a blaze at Mew Milford High School Tuesday afternoon. According to officials one firefighter was treated for heat exhaustion and one was tested for an abrasion. Mayor Pete Bass believes that a roofing project could be a contributing factor as flames could be seen coming out the top of the building at about 2:15pm. Superintendent Alicia DiCorpo says students in the summer school program were all on their buses when the fire broke out. Classes will not be held at the school Wednesday and school officials are evaluating options for where and when they will resume. An assessment of the damage is needed. This is the second fire at New Milford High School in recent months. A blaze broke out in December, also during roof construction, and students were forced to evacuate. At that time, classes were canceled the next day.
