Four people were taken to the hospital with minor symptoms after a carbon monoxide emergency Friday morning in Kansas City, Missouri, according to fire officials.
The Kansas City, Missouri, Fire Department said crews were called shortly after 8:30 a.m. to NE Underground Drive near Missouri 210 Highway after receiving reports of an unconscious person at a facility.
While the first emergency crews were still on their way, 911 dispatchers received additional information that more people at the location were feeling ill. That prompted a broader emergency response, including hazardous materials crews.
Haz-Mat Crews Respond To Facility
When firefighters and haz-mat teams arrived, they worked to identify the affected area and remove people from the building. Officials said the remaining occupants were evacuated as crews investigated the possible carbon monoxide exposure.
Haz-mat crews recorded carbon monoxide readings of 30 parts per million inside the facility. Carbon monoxide is a colorless, odorless gas that can be dangerous because people may not realize they are being exposed until symptoms appear.
Emergency responders evaluated 21 people at the scene for possible carbon monoxide illness. Four of them were transported to an area hospital with minor symptoms, according to the fire department spokesperson.
Facility Ventilated After Elevated Readings
After people were evaluated and treated, haz-mat crews began ventilating the facility to clear the air and reduce the carbon monoxide level.
Officials said crews later recorded carbon monoxide readings of zero parts per million by 10:45 a.m., indicating the immediate hazard had been cleared.
Authorities did not immediately release details about what caused the carbon monoxide buildup or whether the facility would require additional inspection before normal operations resumed.
Symptoms Of Carbon Monoxide Exposure
Carbon monoxide exposure can cause symptoms such as headache, dizziness, weakness, nausea, confusion, chest discomfort, and shortness of breath. In more serious cases, it can lead to unconsciousness or death.
Because carbon monoxide cannot be seen or smelled, officials often urge homes and businesses to use working carbon monoxide detectors. Early detection can help prevent serious injury, especially in enclosed spaces where gas may build up without warning.
Friday’s incident showed how quickly a suspected exposure can become a larger emergency when multiple people begin reporting symptoms at the same location.
Investigation And Safety Review Expected
Fire officials have not said whether equipment failure, ventilation issues, or another source contributed to the carbon monoxide reading. Further review may determine how the gas entered the facility and whether any repairs or safety measures are needed.
No life-threatening injuries were reported, and the four hospitalized individuals were described as having minor symptoms.
A carbon monoxide emergency in Kansas City, Missouri, led to 21 people being evaluated and four people being hospitalized Friday morning.
Haz-mat crews evacuated the facility, found carbon monoxide readings of 30 parts per million, and ventilated the building until readings returned to zero.
Officials have not yet confirmed the source of the gas, and the incident remains a reminder of the importance of fast emergency response and carbon monoxide safety precautions.
