The Syracuse Academy of Science is admitting what it thought was a combination carbon monoxide/smoke detector unit in the building’s cafeteria was just a smoke detector, in a statement released to NewsChannel 9.

Five school employees were transported to hospitals with symptoms consistent with mild to moderate exposure to carbon monoxide.

The Syracuse Academy of Science did not have carbon monoxide alarms in the cafeteria where a school employee was found dead and five others were hospitalized due to possible poisoning, an inspection by the Syracuse Fire and Codes Departments found.

City has ordered the Syracuse Academy of Science to remain closed until detectors are installed. School officials say man's death unrelated to the gas
