Ewing Township, NJ. Ewing fire companies responded to the TCNJ campus to a report of an odor of smoke and then a second call for an odor of gas in one of the dorm halls Tuesday morning. All students evacuated from the building, and Firefighters from the West Trenton fire company investigated and determined not to be any hazard. Firefighters also responded to the Powerhouse on the campus in lot 15 for an odor of smoke coming from the roof. The chief called all hands after midnight; firefighters gained entry to the roof and determined the source and had to cut an object on the roof that was not visible to Peterson’s. The fire chief later placed the fire under control just before 1:00 Am. The fire remains under investigation by local officials and the New Jersey state fire Marshal.
