Four employees were sent to hospital, with two having to be airlifted. One of the victims drove to the hospital by private car with a hand injury, WTOC, a Georgia-based news channel, reported.
The fire started at approximately 4.30pm. At the time of the incident on 3 September, Fire Chief Charles Wasdin said he was not 100% sure of the cause, but believed some pellets may have overheated and ignited, causing a big flash and explosion.
Wasdin said the crews were able to maintain the fire well because around a year ago, having experienced a severe fire previously, the company invested in a suppression system. This system helped to save the potential lives of employees and firefighters, as well as saving time putting out the fire, according to the report.
