🗞️ OSHA Cites Miami Concrete Maker After Worker Killed by Unguarded Machine
OSHA cited Adonel Concrete Corp. with nine serious violations and $58,604 in penalties after a worker was fatally injured entering an unguarded concrete block cubing machine in July 2025.
A Miami-area concrete manufacturer faces federal scrutiny following a workplace fatality. The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) cited Adonel Concrete Corp. — operating as Adonel Block Manufacturing Corp. — with nine serious violations stemming from a July 2025 incident in which a worker suffered fatal injuries after entering the unprotected area of a concrete block cubing machine.
The citations reflect a broad pattern of safety failures beyond the immediate cause of death. OSHA found that the facility lacked functioning lockout/tagout (LOTO) procedures — federally required protocols under 29 CFR 1910.147 designed to protect workers from the unexpected release of hazardous energy during servicing, maintenance, or entry into equipment. Electrical panels were found unmarked and locking mechanisms non-operational. The agency also cited the company for failing to maintain an effective hearing conservation program for workers exposed to high noise levels, and for omitting silica hazards from its hazard communication program — a requirement under OSHA's crystalline silica standard applicable to industries like concrete manufacturing.
OSHA assessed $58,604 in penalties. Under the OSHA Review Commission process, Adonel has 15 business days from receipt of the citations to pay, request an informal conference with the area director, or formally contest the findings. The case may be tracked through the OSHA establishment search as the inspection and penalty status evolves.
The incident underscores longstanding regulatory concerns about machine guarding in manufacturing environments. OSHA's machine guarding standard (29 CFR 1910.212) requires that one or more methods of guarding be provided to protect workers from hazards including point-of-operation dangers, ingoing nip points, and rotating parts — a requirement that investigators determined was not met at the Adonel facility.
Key Points
- A worker was fatally injured in July 2025 after entering an unguarded area of a concrete block cubing machine at Adonel Concrete Corp. in Miami.
- OSHA issued nine serious violations covering machine guarding, lockout/tagout failures, unmarked electrical panels, non-operational locking mechanisms, hearing conservation deficiencies, and silica hazard communication gaps.
- The agency assessed $58,604 in penalties; the company has 15 business days to comply, seek an informal conference, or contest before the Occupational Safety and Health Review Commission.
- The citation reflects multiple overlapping safety failures — not merely the single mechanical defect that caused the fatality.
- Silica exposure is a recognized occupational hazard in concrete manufacturing; the citation documents that silica hazards were not incorporated into the company's hazard communication program, a distinct violation from the machine guarding failures that caused the fatality.
