Dexter Shopping Plaza, at 20 Main St. in Windsor Locks, has been evacuated because of a gas leak and the assistant fire chief said the gas is at an explosive level.
It started at Family Dollar, but the main concentration is at Pizza Time.
Connecticut Light & Power is there to turn off the electricity, which is a necessary step before additional crews can proceed.
When they are able, crews will ventilate the pizza place, officials said.
