A woman escaped serious injury after bystanders helped her flee a fire at her house Saturday, a Casper Fire Department press release said.

Firefighters arrived at the home on 605 East 20th Street at about 10:30 a.m. and found smoke and fire originating from a rear bedroom, the release states. Firefighters were able to put out the blaze but there was heavy fire and smoke damage to the bedroom and smoke damage in the rest of the house. The total cost of the blaze was estimated at $100,000.

The home's occupant had fled before firefighters arrived and was taken to Wyoming Medical Center as a precaution. Her injuries did not appear life threatening but her status was not known at the time of the press release.

Investigators said the fire was caused by smoking materials used near a home oxygen supply, the most recent of several such incidents involving home oxygen. The blaze was deemed accidental.

The Fire Department recommends smoking materials never be used in the area of oxygen supply equipment.
