Vancouver firefighters responded to reports by several callers of a vacant house fully engulfed in flames at Northeast Fourth Plain Road and 134th Avenue, east of Orchards on Tuesday night.A crew from nearby Sifton Fire Station arrived at 9:47 p.m. to the home at 6903 N.E. 134th Ave., and said the house had boarded-up windows and flames were flaring through the roof. The roof was about to collapse and firefighters were told not to go inside due to the danger. Instead, firefighters employed a defensive attack and streamed water to control the flames from outside and make sure the fire didn’t spread to other structures, said Capt. Kevin Murray, a fire department spokesman.A commander radioed for police to control traffic because people were driving over their hydrant line.The fire was under control at 10:20 p.m.No one was reported injured.Vancouver Fire responded, even though the home is outside city limits, because of a contract it has with Fire District 5, Murray said.The fire is being investigated by the Clark County Fire Marshal’s Office.The investigation has “a lot of moving parts” because the home is abandoned and there was no power going to the home, Murray said.The owner is James H. Thacker, according to county property records.
