Another house fire in the northern suburb of Kilkenny sparked by the same cause on Tuesday night.

Both blazes prompted a warning from South Australia’s Metropolitan Fire Service for people to ensure their mosquito coils are extinguished correctly.

A fire sparked by a solar panel battery badly damaged another house in Adelaide’s north.

The city’s Metropolitan Fire Service (MFS) warned residents of the batteries’ dangers when it comes to sparking flames.

MFS northern operations commander Stuart Dawes said at the time fires caused by similar batxjmtzywteries need “copious amounts of water” to control.

“These batteries, in general, if they become pierced or exposed to radiant heat or fire, a thermal runaway process may commence whereby the cells of the battery become heated and may cause fire,” he said.

“This can lead to an explosive or volatile toxic situation which may result in a fire in a home, as it has in this case.”
