The decision this case can inform
Contractor experience does not replace task-specific hazard preparation and verified isolation.
Final MSHA investigation. Results apply only to the stated equipment, conditions and observation period.
What the public record actually establishes
- F1
MSHA identified isolation, protective-equipment and site-specific training failures; the report documents corrective retraining and a hazard-training outline.
- F2
A final investigation establishes causes and documented corrective actions.
Facts and reported results are kept separate from the lesson a plant may choose to test.
Operating context
A contractor suffered a fatal arc-flash injury during panel work.
Intervention or finding
MSHA identified isolation, protective-equipment and site-specific training failures; the report documents corrective retraining and a hazard-training outline.
Documented result
A final investigation establishes causes and documented corrective actions.
Plant interpretation
Contractor experience does not replace task-specific hazard preparation and verified isolation.
Transfer boundary
Do not infer correction effectiveness or present-day compliance. Distinct from the existing 1997 Maryneal crane event.
Questions to verify at your plant
These are decision checks, not operating instructions. Resolve them through local risk assessment, technical review, and authorization.
- 01
Use for contractor-interface and commissioning-hazard review, with site-specific electrical safety procedures.
- 02
What equipment, materials and operating conditions differ at your plant?
- 03
What baseline and follow-up evidence would establish whether this change works locally?
