The occupant of a rural Denison home escaped without injury Sunday night after the residence was destroyed in a fire.

Denison Fire Rescue Assistant Chief Mark Escamilla said crews were dispatched to the home in the 5800 block of Helen Drive at approximately 7:45 p.m. after the occupant noticed that a separate storage shed on the property was on fire and called 911.

“It looks like it started from a building on the west side of the house, which was fully involved when they arrived on scene,” Escamilla said. “That, in turn, caught the west side of the house on fire.”

Escamilla said fire crews from Denison, Preston, Locust, Pottsboro and North Texas Regional Airport — Perrin Field all responded to the scene, but their efforts to contain the flames were hindered by a complication with utilities connected to the home.

“They ran into a problem where an electrical line was running over the house,” Escamilla said. “They had to call Oncor to shut the power down. So that eliminated letting them walk over there and spray water because of the safety hazard.”

As the flames moved through the house, Escamilla said crews in five brush trucks were forced to turn their attention to flames and hot spots that developed on the surrounding land.

“It turned into a decent grass fire after that,” Escamilla said. “It took them a little bit to get it out.”

Escamilla said the occupant was not injured and was able to safely remove all pets from the home. The Denison fire chief said he did not know how the fire began, but added that county investigators had not yet visited the scene and would work to determine the cause.
