At least seven people from two families were displaced after two mobile homes caught fire early Tuesday.
In the first incident, firefighters were called at 3:38 a.m. to 1908 E. 19th, where a woman and three children awoke to their home on fire.
"From what I understand, the mother had to get them out through the smoke and flames," said Fire Battalion Chief Bill Stark.
All of the residents were able to get out of the mobile home without injury, he said.
It took firefighters several minutes to get the fire under control. The mobile home was destroyed. Damage was estimated at $15,000.
A cause of the fire had not been determined as of Tuesday night.
Less than four hours after the first fire began, firefighters were called at 7:14 a.m. to a second mobile home fire at 1900 W. 31st.
At least three people who lived in that home were outside when firefighters arrived. There were no injuries.
It took less than five minutes for firefighters to extinguish the second fire.
The home was severely damaged, Stark said. Damage was estimated at $18,000.
The cause of the second fire was discovered to be an electrical short near a water heater, he said.
Residents of both fires were assisted by the local chapter of the American Red Cross, Stark said.
He said that although Lawrence firefighters in the past have been called to two mobile home fires in one day, the timing of Tuesday's fires was unusual.
"To have two trailer fires in less than four hours is very unusual," Stark said.
