Around 7pm the first call went out for a fire at the abandoned factories at Hancock and Railroad Avenue. The site has seen its share of fires over the winter but this time it affected three of the buildings. Several firefighters were overcome with heat exhaustion and by the acidic smoke. Two firefighters have been hospitalized due to heat exhaustion. Trains passing were slowed to a crawl while traveling through the area. The mayor’s office has been recommending residents to keep their windows closed to keep smoke from entering their homes. Shelton, Easton, Fairfield and Trumbull are few of the fire companies that provided mutual aid in fighting this fire.
