HANOVER – Cooking oil left unattended on a stove boiled over and burst into flame early Tuesday evening, causing an estimated $30,000 damage to the interior of a two-story log cabin, Rumford deputy fire Chief Ben Byam said by phone late Tuesday evening.

No one was injured in the 6:15 p.m. blaze at Ken Goddard’s home at 2045 Main St.. His son-in-law and daughter, Denny and Cindy Theriault, who were staying there will be living with relatives for at least two weeks, Byam said. Goddard was on his way back to Maine from Florida on Tuesday.

“It was a structure fire for a little bit,” Byam said. “But they kept it at bay with a garden hose. They did quite a good job. We went in and checked for a few hot spots, then returned to the station.”

Still, the fire destroyed the kitchen, a new stove and microwave, flooring, carpeting, doors, cupboards and charred some timbers. Byam said if the timbers have to be replaced, damage could climb by another $10,000. The home was insured.

Unattended cooking oil fires are very dangerous, he said.

“Once cooking oil touches over, it goes. I’m sure it boiled over. They were outside and noticed it in time. I guess one of them saw smoke or flames,” he said.

At 6:17 p.m., about 20 firefighters and several firetrucks from Andover, Bethel, Newry, Rumford and Woodstock were sent to the fire. Andover fire Chief Ken Dixon and Byam both said that due to the lack of fire hydrants and with the Androscoggin River 300 feet from the cabin, they would have needed the 15,000 total gallons of water provided by the tankers and pumpers if the fire had spread to the exterior.
