Some Lake County residents near the site where the Blue Rhino gas plant exploded say they're not happy it happened so close to their homes, and they don't want to take any second chances if the plant is rebuilt on the same property.

"People in here told me they were going to have petitions drawn up to keep them from coming back to that particular spot there," said Greg Strawbridge, a resident of the Lakeside at Tavares neighborhood, which was evacuated after the massive explosion Monday night.

The neighborhood is about a mile from the plant, where eight workers were injured -- four with severe burns -- after 53,000 gas grill propane tanks exploded, sending some of the tanks flying off the property. One tank damaged a nearby home.

The Lakeside at Tavares subdivision contains about 100 homes, and Strawbridge said things could be much worse, and the company is lucky it was only the 20-pound propane tanks that exploded, and not larger ones at the plant.

"We don't want them back," Strawbridge said. "If those big tanks would have blown up, chances are a lot of us wouldn't be here."

Residents said while they know if Blue Rhino doesn't rebuild, people will lose their jobs, human life should weigh heavily on the decision to rebuild on-site or somewhere else.

Federal investigators completed an on-site investigation and said there was no indication that a crime was committed that would have caused the explosion.

The Florida state Fire Marshal's Office and the Bureau of Alcohol, Tobacco, Firearms and Explosives searched several acres of the Blue Rhino facility, and said they found nothing that would suggest criminal activity at the plant.

Investigators would not comment on whether a spark from a forklift had anything to do with the explosion, but Tavares Fire Chief Richard Keith had initially said it looked like human error or equipment failure.

Fire investigators conducted several interviews, looked at photos and all of the evidence. They said they are still working on their investigation.

The response team includes explosive enforcement officers and certified fire investigators who worked an explosion at a fertilizer plant in West, Texas, in April. They seemed to be zeroing in on an area toward the back of the plant as a possible point of origin.

Investigators searched a five-acre area and reviewed surveillance tape, which they said showed a portion of the explosion, but none of the cameras recorded it all.

"Nothing was uncovered that would indicate that a crime was committed here," said Maj. Brandon Ball, with the Florida state Fire Marshal's Office. "We've had interview teams fanned out from Gainesville to Orlando and all over Central Florida, talking to employees, witnesses who may have seen anything."

With the on-site investigation complete, the property will be turned back over to Blue Rhino. Ball called the cleanup daunting.

The Occupational Safety and Health Administration said it is still continuing its own investigation.
