One of the five people transferred to a Georgia burn center after being injured in Saturday’s fatal explosion at International Paper’s Vicksburg Mill was released from the hospital Tuesday, a spokesman said.

The patient, who was not identified, had been listed in good condition at the hospital since Sunday, said Beth Frits with Joseph M. Still Burn Center in Augusta.

Four others remained critical today, she said.

Frits confirmed that two of the four are brothers Kenneth and Robert Townsend.

Richard Muirhead, owner of M-Co., 3737 Mississippi 3, said the Townsends and Marcus Christopher Broome, 28, of Bolton, who was killed in the explosion, were employees of his company, hired to work at IP. He said they were industrial insulators.

The brothers reportedly are the sons of a Raymond police officer, also named Robert Townsend.

Muirhead said others at the burn center were not his employees.

Seventeen people were reported injured in Saturday’s blast, and some reports indicated that at least one burn victim had been transferred from River Region Medical Center in Vicksburg to Baton Rouge General Burn Center. However, that could not be confirmed.

Broome, who leaves a wife, Brooke, and twin 4-year-old girls, died at the scene of the blast, Warren County Coroner Doug Huskey said.

Broome was buried Tuesday in Edwards.

IP officials have said the blast occurred in one of the mill’s two recovery boilers during restarting operations after an annual maintenance shutdown.

IP officials still have not released the names of the injured, saying it’s because they are not IP employees.

The 17 injured in the blast were initially taken to River Region. Most were treated and released.

Representatives with the federal Occupational Safety and Health Administration have been on site since Saturday, but Clyde Payne, director for OSHA in the Jackson area, said he doesn’t expect answers for a while.

“In these situations, OSHA has a six-month statute of limitations for performing investigations, and I expect we’ll need every bit of it.”

Payne added that Saturday marked the first explosion of a recovery boiler in Mississippi. He also said IP’s Vicksburg Mill has had an excellent safety record in the past.

About 400 people, including IP’s 306 regular employees, were at the mill when the boiler exploded. All were accounted for, comapny officials said Saturday.

International Paper, based in Memphis, has operations in North America, Europe, Latin America, Russia, Asia and North Africa. The company has about 51,500 employees, 33,100 in the United States.

The IP explosion came about two weeks before the sixth anniversary of a deadly blast at the Rouse Polymerics plant on U.S. 61 South. Five people were killed, and seven were injured.
