Fort Worth fire crews responded to a home for a carbon monoxide investigation that happened during construction.
Firefighters arrived about 7:30 p.m. to the home in the 2500 block of 5th Avenue.
Contractors were working at the home and were using a construction material that expands and solidifies, fire officials said. A chemical reaction caused smoldering to occur and fill the house with smoke.
