Firefighters and law enforcement personel accompanied Columbia Gas workers on Pleasant Street in North Andover to get check for gas leaks and to lock down the gas meters.
Officials in the Merrimack Valley worked Friday to clear streets and allow residents to return to their homes after gas fires and explosions rocked Lawrence, Andover, and North Andover Thursday.
Columbia Gas, formerly known as Bay State Gas, said in a statement that the outbreak of fires and explosions that caused chaos and fear in the three communities was “a tragic incident.”
Officials are warning residents who return to their homes not to turn on the gas and to immediately evacuate if they smell gas at their home.
Lawrence Mayor Dan Rivera said Friday, “We’re not allowing people back in their homes yet if you’re in South Lawrence.”
Here’s where you can find lists of cleared streets in Andover and North Andover.
