A housing supervisor at the Via Christi Regional Medical Center-St. Francis Campus says the man is in serious condition Monday night. His name was not immediately released.
The fire reportedly started around 1:15 p.m. Monday on the assembly line where propane tanks are filled.
Fire officials say the fire did not spread beyond the area where the initial flash happened.
The Wichita-based camping and equipment maker has canceled its second and third shifts at the plant.
The cause of the explosion is under investigation.
