The Greenwich Fire Dept responded to an underground fire and high carbon monoxide levels on Greenwich Avenue on Thursday night, and a portion of the Avenue was closed for a time.
According to a post on their Facebook page, on Greenwich Ave, “manholes carry high voltage electric lines under ground. In the winter time it’s common from the melting snow and salt to corrode these lines. The results of these fires is the potential for high levels of carbon monoxide (CO) in the surrounding buildings.”
The Fired Dept said their units gained entry to several residences and encountered high CO levels.
They ventilated the buildings, reduced the CO levels and awaited the arrival of Eversource.
Engines 1, 2, 3, 4 and 8. Truck 1, Patrol 2, Squad 1 and Car 4 responded.
“Thank you to Ladder 4 Glenville and Station 6 who manned their apparatus to cover the town during this operation,” the Fire Dept said in their post.
In a Facebook post Friday, the GFD said manholes along Greenwich Avenue carry high voltage electric lines underground, and in the winter, it’s common for melting snow and salt to corrode the lines.
As a result, high levels of carbon monoxide can occur in surrounding buildings.
“Our units gained entry to several occupancies and encountered high CO levels. Units ventilated the buildings and reduced the CO levels and awaited the arrival of Eversource,” the GFD said on Facebook.
Greenwich Avenue was closed between Havemeyer Place and Elm Street for several hours late Thursday into Friday.
Overall, Engines 1, 2, 3, 4 and 8 responded, along with Truck 1, Patrol 2, Squad 1 and Car 4. Ladder 4 Glenville and Station 6 covered the rest of the town while units worked on Greenwich Avenue, the GFD said.
