One woman was taken to UPMC Mercy Hospital with a burn injury following a house fire today on Pillar Drive. 

Moon Police Officer James Kazmierczak said the woman suffered a burned hand in the blaze, which ignited in an upstairs bedroom.

Kazmierczak said the home at 161 Pillar, one in a block of townhomes on the street, was heavily damaged. Firefighters said that flames raged up through the building's roof. 

Moon Fire Chief John Scott said the injured woman attempted to put out a fire burning in a bedroom mattress. 

Five people were in the home at the time of the incident. Each escaped before emergency personnel arrived. 

Crews responded to the fire at 11:24 a.m., the officer said. Each of the adjoining townhomes were evacuated, though the fire did not spread to another unit.

Scott said heavy smoke consumed the house and flames burned from the bedroom upwards to the roof. 

Scott said firewalls prevented the blaze from spreading to another townhome unit. 

"Everybody was out when police arrived," he said. "And then they were beating on doors to get everybody out of the other townhomes." 

The American Red Cross is assisting the family, Kazmierczak said.

The cause of the fire is still under investigation.
