Officials were investigating at an Indianapolis Rolls-Royce plant Monday following a nitric acid spill that injured several employees.
Indiana Occupational Safety and Health Administration (IOSHA) workers were on site at the Tibbs Avenue Rolls-Royce Plant 5 location where a 250-gallon nitric acid tank leaked, sending eight employees to the hospital Friday afternoon.
The company is working to determine how the leak happened.
All employees who were injured were treated and released from the hospital Friday evening.
Rolls-Royce Vice President of Communication Joel Reuter said production at the plant resumed Saturday morning.
