OSHA cites both South Dakota refinery, construction companies after
worker suffers fatal burns when ethanol ignites during expansion project
Investigators find multiple safety violations for mishandling hazardous products
HUDSON, S.D. - Federal investigators found multiple safety violations at a South Dakota ethanol refinery expansion project after a 38-year-old pipefitter suffered fatal burn injuries when ethanol spilled from a process pipe he was working on and was ignited by flames from nearby welding operations.
On Nov. 1, 2016, the U.S. Department of Labor's Occupational Safety and Health Administration issued five serious safety violations to the worker's employer Bilfinger-Westcon, the project's construction contractor. Inspectors determined the contractor allowed welding work to occur without verifying that the area was free of flammable liquids.
OSHA cited the refinery operator and owner, Sioux River Ethanol LLC which operates as Poet Biorefining-Hudson, for three serious violations of OSHA's process safety management standards including failing to ensure the process pipe being removed did not contain ethanol.
"This death was needless and preventable if critical safety standards had been followed," said Sheila Stanley, OSHA's area director in Sioux Falls. "Communication between the host employer and all contractors is critical in working safely at any site covered by the Process Safety Management Standard. All aspects of permit systems including 'hot work' and line break must be implemented to ensure that welding activities do not occur near line break activities where flammable materials may be released."
Agency investigators determined the pipefitter was removing a vent line on the sixth floor of the refinery's distillation building on May 6, 2016, when the incident occurred. As he detached a nine-foot segment of this line, 190-proof ethanol spilled onto him, flowed through the grated flooring, and ignited on the fourth floor due to the welding operations occurring there. The resulting fire engulfed the worker, causing fatal injuries that led to his death the following day.
The agency cited his employer Bilfinger-Westcon for:
- Conducting welding operations in an area where flammable liquids could be present.
- Failing to provide flame retardant clothing.
- Not training workers in procedures for process safety procedures and hazards, associated with working in a processing facility.
OSHA has proposed penalties of $62,355. Based in Bismarck, North Dakota, Bilfinger-Westcon is a diversified industrial construction company that provides construction services to large industrial processing facilities throughout the nation. View current citations here.
The agency cited Poet Biorefining-Hudson for failing to:
- Inform contractors working at their facility of the hazards related to ethanol processing.
- Implement written procedures to conduct shutdown activities including verifying the process piping did not contain ethanol.
- Ensure safe work practices including controlling the entrance, presence and exit of contract workers within the process area.
OSHA has proposed penalties of $37,413 to the Hudson-based company, a leading producer of ethanol and other biorefined products, operating more than 25 U.S. facilities. View current citations here.
Both companies have 15 business days from receipt of its citations and penalties to comply, request an informal conference with OSHA's area director, or contest the findings before the independent Occupational Safety and Health Review Commission.
To ask questions, obtain compliance assistance, file a complaint, or report amputations, eye loss, workplace hospitalizations, fatalities or situations posing imminent danger to workers, the public should call OSHA's toll-free hotline at 800-321-OSHA (6742) or the agency's South Dakota Area Office at 605-251-2021.
Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA's role is to ensure these conditions for America's working men and women by setting and enforcing standards, and providing training, education and assistance.

HUDSON, SD – OSHA is investigating a fatal fire at a South Dakota ethanol plant that killed one worker and another injured in the May 6 fire at a POET Biorefining plant south of Hudson.
The cause of the fire hasn’t been determined, but the Occupational Safety and Health Administration says the worker who died was welding inside a tank at the time. The welder was flown to a Minnesota burn hospital, where he died. The other worker was treated at a hospital and released.
Both contractors were employed by Bismarck, N.D.-based Bilfinger Westcon Industries, an industrial construction company. Neither employee’s name has been released.
The South Dakota OSHA office is also investigating the death of a worker who fell from a roof in Watertown in April. Justin Althoff, 24, died after falling 35 feet from the roof of the Watertown Recreation Center.
In late April, OSHA issued fines against two companies for the death of a Brandon man killed when a storage tank he was welding on exploded. South Dakota Soybean Processors of Volga was fined a total of $25,510 and CCM Welding Repair and Fabrication of Minneota, Minn. was fined $11,200. Neither company measured the flammability of the soap stock inside the tank, vapors from which caught fire and caused the explosion.
In 2015, Sioux Falls company Josten Concrete Products was fined $10,720 after a worker was crushed to death by a 3,200-pound culvert in July 2014. OSHA said the company did not take steps to protect employees from objects that could fall and cause serious injury.
