(Cedar City, UT) — A southern Utah school is going online while an investigation into possible carbon monoxide exposure plays out. The Iron County School District announced Canyon View Middle School would be doing remote learning yesterday and today. The decision was made after multiple people became ill following possible exposure to the harmful gas, although the building has been tested and cleared half a dozen times as of Sunday. Another group was expected to come in and do more testing on the alarms while students were off campus yesterday.
