TAVARES, Fla. - TAVARES, Fla. - A series of massive explosions rocked a propane facility in Tavares, Florida, injuring at least eight employees overnight Monday into Tuesday, according to officials.
Officials say most of the eight injured were being treated for burns and other related injuries.
A Lake County Sheriff's spokesperson said at a 2 a.m. news conference that all employees were accounted for after 15 were believed to have been missing.
Seven employees, out of 24 to 26 employees scheduled to work Monday night, have been hospitalized following the massive explosion that began around 10:30 p.m.
The spokesperson said the plant facility's management stated all employees known to have been at the facility Monday night had been accounted for.
He said it appeared many of them left the scene after the explosions began and later came back to report in to management and emergency officials.
According to the spokesperson, victims are at hospitals in the immediate area and some have been flown to major triage hospitals in the nearby cities of Orlando, Ocala and Gainesville.
Two or three victims self-transported themselves to nearby hospitals.
The spokesperson cautioned that a search would be required before a final report on the number of victims.
Officials are not yet speculating on what caused of the explosions. The sheriff's spokesperson said there were around 53,000 20-pound propane tanks at the tank-refurbishing plant.
The sheriff's spokesperson said initial information appeared to show that most, if not all, the plant's employees were in another area of the facility at the time of the explosions.
Lake County Sheriff Gary Borders told the Associated Press blasts occurred inside the plant and blew the roof off at least part of the facility.
Explosions and fires started dying down between 12 a.m. and 1a.m., but smaller fires continued past 1:30 a.m.
According to witness Ashley McCormick, she and her husband were sitting in their home, across Lake Dora from the plant, when they heard what sounded like multiple rolls of thunder.
"As you listened to it more, it sounded like a lot of explosions," McCormick told ABC Action News by phone early Tuesday morning. "The sky was bright orange and it was flashing."
Around 12:54 a.m., firefighters were seen putting water on some fires around the plant, but the fires still burning in the plant were deemed too dangerous to put out. At one point, more than 100 emergency personnel were on scene.
The area around the plant is industrial, but there are homes in the surrounding area. "It is a very large propane plant," McCormick said. "Hundreds of propane tanks."
An initial evacuation area of 1 mile was moved back to only a half-mile, and was lifted by 3 a.m.
