The carbon monoxide and carbon dioxide levels were tested in the Performing Arts Center. No carbon monoxide was detected, and the carbon dioxide levels were normal.

Administrators said they would be reviewing the HVAC systems to ensure there was proper air circulation at the time "as the temperature was warmer than normal."

The middle school choir concert scheduled for Thursday night was postponed. The high school choir concert was set to proceed as scheduled.
