No one was injured in an apartment fire Jan. 26 at 30 George St.
After an investigation, the West Milford Fire Marshal’s Office ruled the blaze was accidental and caused by a failure of lithium ion batteries in a laptop computer.
West Milford Fire Companies 3 and 6 were dispatched about 4:40 p.m. on a report of fire. They confirmed that a fire had occurred but it was extinguished before they arrived.
The occupants came home to find severe heat and smoke damage on the second floor, officials said.
