An explosion at the Diamond Pet Food facility in Lathrop, California burned three employees on Sunday morning.
Their injuries were serious enough that the employees were flown to the University of California, Davis, Regional Burn Center.
Fire Protection District Battalion Chief Gene Neely said the employees were welding in the tower of the pet food facility. The incident is still being investigated.
Neely said: “We believe that the welding operations in connection with the dust from the dog food caused the explosion in the tower.”
Safety checks by fire crews were conducted on Monday morning.
Diamond Pet Food officials did not return any phone calls for comments.
