Initial Explosion Ripped Through Gasoline Creation Unit
A week after a Wisconsin oil refinery explosion, investigators and company
officials are finally releasing essential information related to the cause
of the accident. They jointly released a statement that indicates the
initial explosion at the Husky Energy refinery in Superior, Wisconsin,
occurred in the fluid catalytic cracking (FCC) unit. This information
was confirmed by the U.S. Chemical Safety and Hazard Investigation Board.
The FCC unit is the part of a refinery in which crude oil is heated and
extraction occurs to create gasoline and other petroleum-based products.
Hazardous chemicals are also involved in the heating and extraction process
in the FCC unit. These hazardous chemicals include hydrogen fluoride.
Although the location of the primary explosion is now revealed, investigators
have not yet announced why the FCC unit failed. The U.S. Chemical Safety
and Hazard Investigation Board backed up lack of information at the moment
and stated that not enough data has been gathered and analyzed to definitively
state why the FCC unit failed and the explosion occurred.
Forced Evacuation After Explosion
In the aftermath of the Wisconsin oil refinery explosion, a state of emergency
was declared and thousands of nearby residents were forced to evacuate
their homes. The evacuation was not ordered as a result of the intense
fire or fear that it would spread. Moreover, the state of emergency was
not declared out of a concern that additional explosions might harm the
public in the proximity of the refinery.
Rather, the state of emergency and mandatory evacuation were ordered because
of the possible release of hydrogen fluoride in the massive smoke plumes
that blew out following the explosion. Because this dangerous chemical
is used in the FCC unit as part of the refining process, the preliminary
conclusion has been that the smoke plumes contained that gas.
As noted, hydrogen fluoride is described as a highly dangerous gas. When
the gas comes into contact with moisture, it forms "corrosive and
penetrating hydrofluoric acid upon contact with moisture," according
to the Occupational Safety and Health Administration. In addition, the
gas can cause blindness by rapid destruction of the corneas.
Public Officials Call for Ban on Hydrogen Fluoride
In the aftermath of the Wisconsin oil refinery explosion, public officials,
including mayors in communities near the plant, called for a ban on the
use of hydrogen fluoride in the petroleum refining process. The Mayor
of Duluth, Wisconsin stated:
"We welcome their investment in our economies and the good paying
jobs this work provides. However, choosing the known risks of hydrogen
fluoride is not something that is in keeping with the premise of being
a good corporate partner. It elevates the danger to our environment and
our people." In response, the refinery stated that it could consider
alternatives to hydrogen fluoride during the plant rebuilding process.
Immediate Injuries in Wisconsin Oil Refinery Explosion
Six people were taken to area hospitals in the immediate aftermath of the
Wisconsin oil refinery explosion. There were no fatalities. The status
of all six injured people was not available. The speculation was that
they had all been released from hospitals a week after the explosion.
No other details were available on their injuries.
Injuries to General Public
Investigators have not released any information about the specific impact
the release of hydrogen fluoride, or other harmful gasses or substances,
may have had on members of the general public. Indeed, it is possible
that members of the public could have faced exposure to harmful chemicals
as a result of the explosion that results in health complications that
may not become evident for some time.
