Authorities say two workers have been burned in an accident at a food plant in Norfolk.
Norfolk Fire Capt. Lyle Lutt says firetrucks were sent to the Henningsen Foods plant around 1:20 p.m. Wednesday.
The propane tank fire that prompted the 911 call had already been extinguished. But as workers checked the propane system, propane spewed out of a pressure relieve valve and was ignited by a pilot light on a nearby machine.
Lutt says that new fire soon ignited gas coming from a pressure relief fitting on another machine.
Lutt says two plant workers suffered second-degree burns on their faces, heads and arms.
They were treated by firefighter medics but not hospitalized.
