The state fire marshal's office says they're still trying to determine the exact cause of fires that hit two Central Georgia factories last week. A spokesman says neither fire appears suspicious.
The state agency and local investigators are still sifting through evidence on Wednesday's fire at the Pactiv factory in south Bibb County and Thursday night's blaze at the Southern Perfections sheet-metal plant in Byron.
That's according to Glenn Allen, spokesman for the state fire marshal's office.
The Pactiv fire apparently began in an area when workers stack hot, newly made paper egg cartons that are heated in an oven.
But so far, investigators haven't determined how the cartons caught fire.
Allen says investigators believe the Southern Perfections fire started in a welding and spray-painting building.
He said neither fire appears to be suspicious.
Fire officials may bring in electrical engineers to study both sites and help them identify possible causes, he said.
