ROCKLAND (NEWS CENTER Maine) -- At the sight of the flames pouring out of a second story window at a Rockland apartment building, firefighters immediately sounded a second alarm.

The fire at 175 Rankin St. brought crews to the multi-unit housing complex at about 6:30 p.m. on Monday.

Even before firefighters arrived, they knew from the person who initially called for help that all of the tenants got out of the building safely.

Firefighters used about 750 gallons of water to snuff out the flames. Chief Chris Whytock said the fire was mostly contained to the apartment where it started with minimal smoke and water damage to surrounding units.

Two people live in the fire's apartment of origin, in addition to five more tenants in the rest of the building. None of them were injured. Whytock said most of them are staying with friends and family.
