“One guy with a laceration from a piece of glass, one guy that went to the hospital with a medical event, but he should be fine and two others that were evaluated for heat-related exposure,” said Etna Fire Chief Greg Porter. “Once that fire starts it’s onto that house very quickly. Small, old town. Fire travels very fast.”

All four are expected to be okay.

Ten people were displaced due to the fire but they were able to get out safely along with two cats.
