School officials said the Trumbull Fire Department determined that the building was safe to be occupied and a restoration company was called in and assessed the situation.
It was determined that the restoration company, working with the custodial team, could clean up the glycol and that school could begin on a delayed schedule, Semmel said.
Less than six hours after the initial call, at 3:04 a.m. on Friday, a call came in from a Nichols firefighter who was working maintenance at the high school with a report of smoke in the building and dispatchers also received an alarm from smoke detectors in the school, according to Trumbull Volunteer Fire Company, No. 1.
Crews then found smoke from a small electrical fire from a power cord and extinguished the fire.
The fire department said the fire marshal’s office responded to both calls.
