UPDATE: All Safe After Large Fire on Orchard Street

All occupants - incuding pets - are accounted for after a two-alarm fire consumed the front of a 2.5-story home at 67 Orchard St. early Sunday evening. 

Calls for the fire, which came in just before 5:30 p.m., brought mutual aid from Revere, Medford and Everett fire departments. 

The fire was declared knocked down about 45 minutes later, at 6:15 p.m. 

Several witnesses reported hearing 3 or more explosions related to the fire, though their origin was not immediately clear. Firefighters were later commanded to evacuate the building due to concerns about the structure's stability. 

The damage wasn't limited to just 67 Orchard - the siding on some of their neighbor's homes appeared to be melting and falling off of the exterior. 

James Labbe, captain of the local Salvation Army chapter, said he spoke to the victims. 

"They were very stressed and upset, but with the assistance of the Deputy (Fire Chief) we were able to determine that they had a place to go to and at this point in time needed no assistance," he said. 

According to a friend of the family, only one resident was home at the time of the incident.
