Ten Mouldings Unlimited employees, who last night could have been working the third shift, were not there when explosions shook the city of White and flames began to engulf the manufacturing plant, threatening nearby structures, CBS Atlanta reports.

"It was shaking my whole house. It woke up my daughter and I was like, 'Get your clothes together,'" nearby resident Amanda Thompson told WSB-TV.

"It rattled the windows. It was really loud, like cannons going off," a man said of the explosions, according to the TV station.

Last week, the plant halted its third shift due to slow business, CBS reports. Mouldings Unlimited employs a total of 25.

Its historic old mill alongside Highway 411, built in 1962, has been destroyed in the blaze that could continue to burn through Monday, according to Fox 5 and CBS.

City of White officials have been concerned about water supply and water pressure, and Bartow Fire Chief Craig Millsap said wood products stored in the manufacturing facility are creating a challenge for suppression crews, Fox 5 reports.
