The Hoeganaes Plant in Gallatin, TN is the world leader in the production of Atomized Steel and Iron Powders. Iron powder production involves handling two (2) potentially deadly materials – combustible dust and hydrogen gas. When properly handled, the risks associated with these materials can be mitigated. When the risks are ignored, however, the consequences can be devastating.

In three (3) separate incidents between January, 2011 and May, 2011, explosions and flash fires rocked the Gallatin plant – killing five (5) workers and injuring several others. In all three (3) incidents, iron powder particles either fueled the original fire or fueled secondary explosions that led to greater injury, death and property damage.

In this course, you’ll learn how design errors, complacency and lack of employee training led to the deaths of five (5) men. You’ll see how the hazards associated with combustible dust were ignored and how housecleaning and ventilation systems were inadequate. You’ll learn how the design of equipment and even structural members facilitated the accumulation of deadly combustible dust particles.

In short, you’ll learn what shortcomings were present in the plant’s design, training, safety precautions, and procedures so that you can apply these learnings to the execution of your projects.
