The Syracuse Academy of Science Charter School superintendent gave Spectrum News 1 a tour of the school Wednesday, a day before it reopens to students after the death of an employee and the finding of elevated levels of carbon monoxide in a part of the building two weeks ago.

Superintendent Tolga Hayali showed off safety improvements to SAS High School as it prepares to welcome back students. The school closed Jan. 7, when authorities responded to a call involving a member of the night crew, later identified as Brian Deforge, 46, that passed away in the cafeteria. 

The medical examiner's official report on his death has not yet been released, so his official cause of death is not known. The school has said the elevated carbon monoxide levels and Deforge's death are unrelated.

Several other employees were evaluated for exposure to carbon monoxide. Firefighters found high levels of carbon monoxide, leading the school to close and shift to remote classes. Syracuse code enforcement officials issued eight violations to the school.

Hayali said all of the school's fire alarms and kitchen equipment needed reinspection, and they also had to establish new hardwire and monitor carbon monoxide detectors across the whole school. The superintendent said the school is now approved for use again, and parents had the opportunity to visit last night and ask questions.

"At the end of the day, it's all about the children," Hayali said. "That's our main focus, and making sure that our children will come back and continue their learning."

We reached out to the medical examiner's office to find out a timeline for learning a cause of death.

The school released an updated Regents schedule and updates about the incident here.
