The cause of Monday’s explosion at Amalgamated Sugar Company factory in Nampa, Idaho, is still under investigation by company officials.
Jessica Anderson, a spokeswoman for Amalgamated Sugar, said the incident—which occurred at about 7:45 a.m. Monday and injured five employees, sending one to a local hospital—didn’t halt production or cause any damage to the sugarbeet pulp steam dryer, where the explosion occurred.
Anderson said the hospitalized employee was treated and released the same day. The other four were treated with minor first aid at the factory.
The incident also is being investigated by the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA).
On Monday, a DOL spokesperson confirmed the OSHA investigation. The individual said the explosion is currently an open case, and “we cannot provide further information or details at this time.”
