Crews responded to a working fire call at the Bucks County Meadows Apartments on Knights Road just after 5 p.m., according to Bensalem Fire Rescue.
Firefighters stretched two waterlines to the smoke-filled building, allowing the kitchen fire to be quickly extinguished, officials said.
An unconscious victim was rescued from the apartment by Bensalem Police and rushed to an area hospital by Bensalem EMS.
The cause of the fire was determined to be accidental in nature due to "careless cooking," fire officials said.
No other injures were reported.
