Incident Overview
On the evening of August 7, a worker was killed at the Ryobi Die Casting (USA) Inc. facility in Shelbyville, Indiana. Ryobi, a subsidiary of Japan-based Ryobi Limited, confirmed the fatality but has not released the employee’s identity or further details about the incident. The plant produces aluminum castings for automotive and structural applications using a high-pressure die-casting process that requires equipment to cool for 24 to 48 hours before investigators can safely access the site.
Investigation and Agency Response
Local and state authorities were immediately called to the scene. The Shelby County Coroner’s Office, Shelbyville Police Department, and Shelbyville Fire Department responded, joined by the Indiana Department of Homeland Security, the Indiana Occupational Safety and Health Administration (OSHA), and the Indiana State Fire Marshal’s Office. These agencies are conducting a joint death investigation, with the cooling period of the equipment expected to extend the time needed to complete forensic analysis and identification procedures.
Company Response
Ryobi issued a statement emphasizing that employee safety is its “highest priority.” The company said it is fully cooperating with OSHA and other authorities, while also launching an internal review of the incident. Ryobi announced that counseling and other support resources are being provided to employees and families, and it requested privacy for the deceased worker’s relatives during the ongoing investigation.
Workforce and Facility Details
The Shelbyville plant employs more than 700 workers and is part of Ryobi’s global network of facilities, which also includes sites in China, Japan, Mexico, Thailand, and the United Kingdom. The plant’s operations involve melting aluminum and injecting it under high pressure into steel dies, a process that generates the rapid cooling requirements cited by investigators.
Next Steps
Authorities will continue to process the scene once the equipment has cooled, after which the coroner’s office will work to confirm the cause of death. Ryobi has pledged to release additional information as it becomes available and to maintain cooperation with all investigative bodies.
