GALLATIN, Tenn. (AP) — Three workers have been critically injured in an explosion at a Middle Tennessee chemical plant where a January flash fire killed another worker.
Gallatin Police said the accident that injured five at the Hoeganaes (HAY'-gan-eez) Corp. plant was reported at 6:37 a.m. Friday.
A Vanderbilt University Medical Center spokeswoman said three of the injured were brought to the burn unit by helicopter.
This is the third accident this year at the plant that employs about 175 workers and makes metal powders for automotive and industrial uses.
A U.S. Chemical Safety Board investigator criticized the company only two weeks ago, saying plant officials knew about the danger and did not adequately address it.
A telephone message left for spokeswoman Marcie Wurst at Hoeganaes headquarters in Cinnaminson, N.J., was not immediately returned.
