A massive fire broke out early Thursday morning behind a Nursery Supplies, Inc., plant in Kissimmee, Florida. The fire spread over five acres behind the plant and burned thousands of plastic pots, sending flames and smoke into the sky. Deputy Chief Jon Haskett with Osceola County Fire Rescue said at a press conference that 75 firefighters and 21 vehicles were dispatched to extinguish the massive inferno. The cause of the fire has not yet been found. Fire officials said they are closely monitoring the air quality due to the potential release of hazardous materials from the burning plastic. There is no report of the release of hazardous chemicals at this time.
