Eight people were transferred to a hospital for medical evaluation after a carbon monoxide leak at a Missouri elementary school on Oct. 19.
Six students and two adults from Longfellow Elementary School were taken to the hospital after feeling nausea and dizziness. They are in a non-life-threatening situation, Assistant Fire Chief Jimmy Walker said.
Responders arrived at the school after students reported feeling ill.
Firefighters found “extremely high” levels of carbon monoxide inside the building. Their detectors showed 2,000 parts of carbon monoxide per million, which was the maximum possible level their detectors could show.
The cause of the leakage is under investigation. Firefighters were ventilating the building, and classes are expected to resume Friday, reported KMBC News.
School district spokesperson Elle Moxley said the district had contractors check its heating systems last week, including at Longfellow. No problems were detected, she said.
Moxley said every child was checked and the district worked with the fire department to determine when classes would restart
