Related to uncontrolled exposure to potentially dangerous levels of carbon monoxide at the Idaho Cleanup Project.
On January 31, 2024, the U.S. Department of Energy (DOE) Office of Enterprise Assessments, Office of Enforcement issued Enforcement Letter (WEL-2024-02) to Idaho Environmental Coalition, LLC for deficiencies in implementing DOE’s 10 C.F.R. Part 851 Worker Safety and Health Program requirements related to uncontrolled exposure to potentially dangerous levels of carbon monoxide at the Idaho Cleanup Project.
Enforcement Letter, Idaho Environmental Coalition, LLC | Department of Energy
“The event occurred on January 10, 2023, when workers were operating a
gasoline-powered welder generator inside the NRF-601 high bay. Earlier in the
day, IEC approved a work order change (WOC) for work order number 597489 to
move the generator from outdoors to inside the high bay. The WOC included a
warning that the generator produced harmful emissions that constituted a
respiratory hazard. In response to the WOC, workers established a safety
boundary around the generator, inserted a flex pipe into the exhaust stack, and
passed the flex pipe through the wall of the building to the outside…
…IEC did not report the CO exposure on the Occupational Safety and Health
Administration Form 300 or in the DOE Computerized Accident Incident
Reporting System database due to a misinterpretation of occupational exposure
reporting requirements.”

Source was a gas-powered pump being used inside the house
The Winnipeg Fire Paramedic Service (WFPS) received an emergency call just after 8 p.m. on Wednesday, prompting their immediate response to the construction site. Upon entering the premises, paramedics’ carbon monoxide detectors sounded the alarm, indicating dangerous levels of 2,000 parts per million of the toxic gas inside the house.
Inside the home, the paramedics discovered an unresponsive worker who was being assisted by two bystanders providing medical care. Tragically, the worker could not be saved. Two of the responding paramedics and one of the bystanders were also affected by the toxic gas and required medical treatment.
In a press release, city officials revealed the cause of the carbon monoxide build-up was a gas-powered pump that was operational inside the house.
A spokesperson for the province tells CTV News Winnipeg “a stop-work order has been issued on the gas-powered equipment and WSH is continuing to follow up.”
Carbon monoxide is a colorless, odorless, and tasteless gas, making it extremely difficult to detect without specialized equipment like carbon monoxide detectors. It is often referred to as the “silent killer” because exposure to high levels of this gas can lead to serious health issues and even fatalities. Common symptoms of carbon monoxide poisoning include headaches, nausea, dizziness, confusion, vision and hearing impairment, and shortness of breath.
The construction company involved in the incident, Artista Homes, was approached for comment by CTV News Winnipeg, but did not receive a response.
In the wake of this tragedy, authorities are urging all residents and businesses to take the necessary precautions to prevent carbon monoxide poisoning. It is recommended to install carbon monoxide alarms on every floor of a building, especially in homes and workplaces where gas-powered equipment is utilized.

In 1998, the Iowa Department of Public Health (IDPH) and Iowa State University (ISU) Extension Department, with the assistance of local health departments, investigated a series of carbon monoxide (CO) poisonings associated with the use of liquified petroleum gas (LPG)-powered forklifts in light industry. In each episode, forklifts emitting high CO concentration levels were operated in inadequately ventilated warehouse and production facilities, which resulted in high CO accumulations. Employees at each site developed symptoms of CO poisoning, and some employees received inadequate or inappropriate medical care. This report summarizes the investigations and provides recommendations to prevent such incidents.
