(KAIR)--An early morning Atchison house fire Saturday left the home uninhabitable but no one hurt.

Atchison Fire Chief Patrick Weishaar, in a release, says firefighters were called to 801 M Street, shortlyl after 12:30 Saturday morning, with the front of the two-story home found to be fully engulfed in flames.

Although the home was occupied, the resident was outside when the fire began.

Realizing the home was on fire after it had spread throughout the front rooms, the resident “attempted to enter the structure to retrieve a phone to call 911 but was unable to enter due to the extent of the smoke and flames.” Instead, Weishaar says, it was a passerby who reported the fire.

When firefighters arrived, moments after being notified, the fire had spread to the second floor, with crews “able to quickly bring the fire under control,” although “the structure had already sustained heavy damage.”

Although the cause of the fire has not been determined, Weishaar says the home’s occupant said “a space heater was in use in the area where the fire is believed to have started.”

According to Weishaar’s release, “the resident did not request any assistance and left the scene in the care of a family member.”
