The fire began when a lit cigarette caused a mattress to catch fire and proceeded to engulf the home in flames, according to police.
Upon arrival, police confirmed all residents were evacuated. One resident was treated for slight burns to the hand on the scene by Galloway EMS.
Red Cross and Salvation Army were on hand to assist the four victims with relocation and to provide care for all involved.
The Germania, South Egg Harbor, Pomona, and Cologne Fire Departments all responded to the scene to fight the fire. The Oceanville and Elwood Fire Departments also assisted with the incident.
