If multiple people in your home or business are experiencing shortness of breath, light-headedness, and an elevated heart rate, Ephraim Fire Chief Justin MacDonald does not want you to hesitate to call them about possible high levels of carbon monoxide. That was the case at Crandon School District this week after 39 students, staff members, and EMS workers were hospitalized due to elevated carbon monoxide exposure. According to the Forest County Sheriff’s Department, hazmat workers from Oneida County and Wausau determined on Friday that a mechanical issue with the furnace was to blame for the elevated levels inside the school. The district canceled classes and school events for Friday until the building can be properly vented and the issues are resolved. MacDonald says they do not get a lot of carbon monoxide-related calls, but they do work with the property owners to ensure they are safe before they allow them back inside.

Ultimate Air owner Jeff Blemke says having your furnace properly maintained and a carbon monoxide detector will help protect your family.

According to the Centers for Disease Control, approximately 420 people die and 100,000 people are admitted to emergency rooms every year from accidental CO poisoning.
