Federal workplace safety officials have cited a Wisconsin food manufacturer following two separate pressure-release incidents that resulted in three deaths and two severe injuries earlier this year.
Investigators with the Occupational Safety and Health Administration opened an inquiry into IPMF LLC, which operates as NaturPak, after a clogged vent line caused pressure to build inside an industrial kettle on Feb. 12. The lid opened unexpectedly, spraying steam, scalding liquid and food particles onto two employees, one of whom was also struck by an object. Both workers were hospitalized, and one later died from complications.
On March 18, OSHA inspectors returned to the Janesville facility after a second kettle lid opened under pressure. The resulting release of hot liquid and steam burned three workers, killing two and sending the third to the hospital.
Following the investigations, OSHA cited the employer for serious violations regarding kettle design, thermal burn hazards and a lack of quick access to emergency water. Inspectors also cited the facility for exposing employees to fall hazards around the kettles and failing to evaluate personal protective equipment needs.
Additionally, the agency issued repeat citations after finding the company failed to establish, document and train workers on proper lockout/tagout procedures, which ensure equipment is safely depressurized and powered down.
In total, OSHA proposed $115,850 in penalties for the February incident and $248,250 for the March incident, bringing total fines to $364,100.
The company has 15 business days from receiving the citations to pay the penalties, request an informal conference with an OSHA area director or contest the findings before the Occupational Safety and Health Review Commission.
