There was an explosion and fire in a sidewalk electrical vault on North Main Street in Norwalk Tuesday morning and fortunately, no injuries are reported.
Fire officials responded at 9:35 a.m. and they said the door of the vault in front of 44 North Main St. had blown open and there were flames and heavy black smoke.
Firefighters initially stood by with a hose line and checked the buildings near the vault for any smoke or fire as South Norwalk Electric Works secured power at a substation, fire officials said.
When it was determined that the power was off, the fire was quickly extinguished.
A woman who worked in the area, was discarding some trash in the container near the vault when the explosion happened and was not injured in the blast.
Fire officials said there is no damage to the surrounding buildings, but some shops and offices shut down because they had no electricity.
Once the fire was out, utility crews began work on restoring power to the area.
The buildings in the immediate area that are supplied by the transformer and equipment in the vault will be out for at least the day, fire officials said.
