FORT DODGE, Iowa - Officials say a faulty furnace at a hotel in Fort Dodge put five children in the hospital with carbon monoxide poisoning.

The children were in the swimming pool at the Travel Inn on Saturday evening when they began to feel lethargic and dizzy. A call reporting an unresponsive child was made at about 6:30 p.m.

A strong odor throughout the building led authorities to believe the culprit was chlorine poisoning. But Assistant Fort Dodge Fire Captain Steve Hergenreter says tests discovered levels of carbon monoxide more than 14 times the safe level.

The children were taken to the hospital where excessive levels of carbon monoxide were found in their blood. Their names and conditions were not released.
