4 hospitalized following carbon monoxide leak at home in Kansas City neighborhood
Four people are in serious condition following a carbon monoxide leak at a home near Kansas City’s Scarritt Renaissance neighborhood.
The Kansas City Fire Department was called to the 100 block of Gladstone Boulevard around 10:30 a.m. Monday on reports of an unconscious patient, department spokesperson Riley Nolan said in an email to The Star .
As first-responders began to treat the patient, they noticed symptoms of carbon monoxide poisoning, Nolan said.
Firefighters used a carbon monoxide monitor to test the air quality, and found carbon monoxide levels in the residence were over 600 parts per million, Nolan said. First-responders requested additional ambulances and Spire gas service to the scene, and vented the residence.
Four people, three adults and one juvenile, were transported to area hospitals, Nolan said. Three, including the juvenile, were in serious condition and one adult was in critical condition.
Two additional adults that were inside the residence refused further medical treatment, Nolan said.
Firefighters believe the carbon monoxide leak was caused by an issue with the furnace flue pipe, Nolan said.
The average level of carbon monoxide in a home without a gas stove can range anywhere from 0.5 ppm to 5 ppm, Nolan said. With a gas stove, average levels adjust to 5 ppm to 15 ppm.
Levels over 9 ppm are considered above normal, and indicate an “action level” for the KCFD, Nolan said.
To avoid carbon monoxide leaks, homeowners should install carbon monoxide detectors on each level of their home and near sleeping areas, Nolan said. The detector’s batteries should be checked monthly.
Additionally, furnaces and fireplaces should be checked annually, generators should be used outside the home and garage, and vents for dryers, furnaces, stoves and fireplaces should be clear of debris, Nolan said.
The most common symptoms of carbon monoxide poisoning are “headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion,” Nolan said. Symptoms are often “flu-like” in nature.
If someone suspects they have carbon monoxide poisoning, they should call 911 and move to fresh air immediately, Nolan said.
