A blaze broke out Monday morning at the Innovative Fibers plant in Spartanburg, SC that left four workers with injuries, local news organizations reported.
Sent to the Littlejohn Street location around 10:30 a.m., crews discovered that some people were trapped in the building after arriving at the scene, television news station WSPA said. The fire was quickly doused.
Four injured workers were taken to area hospitals for treatment.
“The fire was caused by an outside contractor performing routine maintenance,” the company said in a statement to broadcaster WYFF. Innovative Fibers said all the injured persons were employees of the contractor.
Powder & Bulk Solids reported in January that a worker was fatally injured after they became trapped in a piece of equipment at the Innovative Fibers plant in Spartanburg, SC.
Innovative Fibers, a subsidiary of Stein Fibers Ltd, is a manufacturer of crimped PET-fibers from recycled materials.
