US Department of Labor cites Miami-based concrete product manufacturer after worker suffers fatal injuries

MIAMI – The U.S. Department of Labor has cited a concrete manufacturer for exposing workers to hazards after an employee suffered fatal injuries after entering the unprotected area of a concrete block cubing machine in July 2025.

The department’s Occupational Safety and Health Administration cited Adonel Concrete Corp. – operating as Adonel Block Manufacturing Corp. – with nine serious violations for inadequate machine guarding, and for failing to ensure lockout/tagout procedures were used, electrical panels were marked and the locking mechanism operational, implement an effective hearing conservation program for workers exposed to high-noise levels, and incorporate silica hazards into the company’s hazard communication program. 

OSHA assessed $58,604 in penalties.
