Branford fire crews responded to 738 East Main St. on Sunday in response to a 1,000 gallon propane tank leak.
Officials said two homes were evacuated for "precautionary purposes" and that the Connecticut Department of Energy and Environmental Protection (DEEP) were on the scene as well.
Officials said a hazmat team responded as well to assist.
It is unclear at this time what caused the leak, but officials said it appears to be accidental.
Crews used “flaring,” which is using a device designed to allow them to “burn off the remaining gas in the tank.”
Officials said the tank was 40 percent full.
