- 29-year-old Dustin Hale and 47-year-old Dennis Gougeon were cleaning out an ash system at Packaging Corporation of America in Tomahawk yesterday when they were hit by fly ash.
Gougeon died of his injuries yesterday evening.
Fly ash from fossil fuels burned Hale and Gougeon.
Both men were flown to the UW-Hospital in Madison originally.
Hale was transported to Regions Hospital Burn Center in St. Paul, Minnesota this morning.
Both are contract employees from Inland Systems, based out of Ontonagon, Michigan.
A woman at Inland Systems says much of the work they do deals with hydro blasting, or high pressure water cleaning.
PCA spokesman Ron Zimmerman says the company contracts a security team that doubles as EMT's on every shift.
Those EMT's responded to the scene.
An EMT from the Rhinelander Fire Department who did not respond to this specific call, says they call for helicopter support when a victim has 2nd or 3rd degree burns covering 30 percent of the body.
"If we're dispatched with a chemical burn we are going to be asking what type of chemical that is, we need to know exactly what it is," Rhinelander F.D. Deputy Chief and EMT Dale Wege said.
"That chemical has to be neutralized or otherwise removed from the patient before any type of treatment can begin. Then it kicks in to how much body surface is involved. Over certain percentages of body area involved kicks in whether we're calling for a helicopter to flight them out to a burn centers."
OSHA launched an investigation as well.
They'll investigate both PCA and Inland Systems.
They'll try and determine whether any health or safety violations occurred.
"They may interview employees," OSHA Spokesperson Rhonda Burke said.
"They'll talk to managers and supervisors, witnesses on the scene. They will look at safety and health procedures that were in place. Then they will complete an investigation."
The investigation could take up to six months.
Any potential penalties depend on what the investigator finds.
PCA violated OSHA standards in 2008 when three people were killed in an explosion and could be deemed a repeat offender.
