Twelve people were taken to area hospitals Saturday after dangerous levels of carbon monoxide were detected at three apartment buildings in Gaithersburg, Maryland, according to Montgomery County Fire and Rescue Service.
Emergency crews were called to the Streamside Apartments on North Summit Avenue around 8:44 a.m. after reports of a possible gas leak and multiple people feeling sick. Firefighters detected high carbon monoxide readings inside one building before finding elevated levels in neighboring buildings.
More than 50 residents were evaluated during the response. Twelve people were ultimately transported to hospitals, including seven children and four adults. The age of the remaining patient was not immediately released.
One child was taken in stable condition to Baltimore Shock Trauma for possible treatment in a hyperbaric chamber, according to local officials.
Oven Identified as Likely Source
Washington Gas was called to the apartment complex to investigate where the carbon monoxide was coming from. The utility later determined that an oven in the building at 422 N. Summit Avenue was the likely source. The appliance was removed from the building.
Firefighters and building maintenance personnel also checked the affected properties to make sure smoke alarms and carbon monoxide detectors were functioning properly.
After the buildings were cleared, residents were permitted to return to their homes. Building management remained at the complex as emergency crews began leaving the scene.
Why Carbon Monoxide Can Be Dangerous
Carbon monoxide is a colorless and odorless gas produced when fuels are burned. Because it cannot be seen or smelled, people may not realize they are being exposed until symptoms begin.
The Centers for Disease Control and Prevention lists headache, dizziness, weakness, nausea, vomiting, chest pain and confusion among the most common symptoms of carbon monoxide poisoning. High exposure can lead to unconsciousness or death.
Residents can reduce the risk by keeping carbon monoxide detectors near sleeping areas, having fuel-burning appliances inspected regularly and making sure those appliances are properly vented. Montgomery County also advises residents never to use an oven or stove to heat a home.
The Gaithersburg incident highlights how quickly carbon monoxide can spread through connected residential buildings and why functioning alarms can provide an important early warning.
