22 sent to hospitals ‘as a precaution’ after high carbon monoxide levels found at Cedar Rapids warehouse

CEDAR RAPIDS — Twenty-two people exposed to elevated levels of carbon monoxide were taken to local hospitals Friday afternoon as fire crews responded to alarms sounding at a southwest quadrant transportation and logistics company, authorities said.

Crews were called about 2:30 p.m. to the warehouse and office of NFI Interactive Logistics, 3110 Prairie Valley Ct. SW. Alarms to detect carbon monoxide were sounding and first responders found “multiple employees feeling unwell,” a news release said.

Firefighters and Area Ambulance crews treated employees for possible carbon monoxide exposure and 22 people were transported to UnityPoint Health-St. Luke’s and Mercy Medical Center for what authorities said was “a precaution for further assessment and treatment.”

Crews said they isolated the facility’s gas lines but the incident remained under investigation.
