A steam explosion injured three workers Thursday morning at the SKF USA Inc. Plant in York County.
Company spokesman Warren Gondolf said the accident injured an SKF employee and two technicians from a furnace manufacturer, Aichelin Heat Treatment Systems Ltd., at the facility on Industrial Drive in Penn Township at around 8:30 a.m.
Gondolf said the accident was caused by an explosion of hot salt solution in the plant's heat treatment area.
The injured workers were flown to Johns Hopkins Bayview Medical Center in Baltimore for treatment of their injuries. Their names and details on their conditions were not available, but emergency officials said they appeared to be in stable condition before they left the scene.
The company and federal authorities are investigating the cause of the accident. The heat treating operation will remain idle while the incident is reviewed.
Gondolf said no hazardous materials were involved and there was no impact on the environment.
