GALLATIN, TN -- Hoeganaes, which experienced three combustible dust explosions and five-related worker deaths last year, has been cited for 11 fire code violations. 

Inspectors of the Gallatin Fire Department wrote up the citations during a Jan. 10 inspection. One of the violations was for a small quantity of combustible metal dust that had accumulated under a conveyor, according to the Tennessean.

Hoeganaes also was cited for not meeting code for emergency lighting, fire alarm and some exit doors.

The three Hoeganaes plant accidents, which occurred on January 31, March 29 and May 27 of last year, killed five workers and injured three others. The U.S. Chemical Safety Board determined that the accidents could have been prevented if Hoeganaes had done a better job of cleaning house and training its employees to exercise more caution in their work.
