Flames tore through an east Medford trailer Wednesday afternoon, sending one person to the hospital with possible smoke inhalation, officials said.

The fire started at 4:45 p.m. inside a trailer near the intersection of East 12th Street and South Riverside Avenue.

Medford fire engines arrived within minutes and doused the fire before it could spread to nearby units and brush, Medford fire Battalion Chief Ken Goodson said.

A woman inside the trailer was taken to Rogue Valley Medical Center, where she was treated for smoke inhalation, Goodson said.

Firefighters were forced to enter the trailer and cut into the walls and floors after flames crept into these narrow spaces, Goodson said.

"It was difficult to deal with," Goodson said.

The fired appeared to have spread throughout the trailer to cause "extensive damage," Goodson said.

"We don't know if anyone will be able to live in it again," Goodson said.

The trailers in this area sit close to one another, which was a concern for the firefighters. "You don't want fires to spread from one residence to another," Goodson said.

The heat of the day was another trial for the fire crews, Goodson said.

"We are taxed to the limit right now," he said. "We have an ambulance on scene in case the heat gets to one of us."

Temperatures hovered in the mid-90s at the time of the fire. Once the flames were extinguished, many of the firefighters on the scene took shelter in the shade and drank bottles of water before continuing the mop-up phase.

Jackson County Fire Districts Nos. 3 and 5 covered calls in Medford as crews finished up at the scene.

"On a hot day like this, anything can turn into a serious fire," Goodson said.

Goodson did not know how many people were displaced by the blaze.

East 12th Street was blocked to traffic as fire investigators entered the residence at around 6 p.m.

The cause of the fire remains under investigation.
