A train carrying highly flammable ethanol derails in Minnesota, sparking an hourslong fire. Now 4 more cars with ethanol could spill

(CNN) — A train hauling ethanol derailed Thursday morning in Raymond, Minnesota, igniting several rail cars and forcing a mandatory evacuation of the city of about 800, officials said.

The fire was still burning more than 8 hours after the derailment, the US Environmental Protection Agency said. An EPA team was in Raymond by 6:30 a.m. to conduct air quality monitoring.

“Four cars containing ethanol, a highly flammable product, ruptured, caught fire and continue to burn,” the EPA said late Thursday morning.

And more ethanol could spill. “Four additional cars containing ethanol may also release,” the EPA said.

The train, operated by BNSF Railway, derailed around 1 a.m. Homes within a half-mile of the derailment were evacuated, the Kandiyohi County Sheriff’s Office said.

“There have been no injuries as a result of the crash or emergency response,” the sheriff’s office posted on Facebook.

The evacuation order was lifted midday Thursday.

“Residents may return safely to their homes. There will be road detours in the area around the site,” the sheriff’s department said. “There is no impact to groundwater. Local responders and BNSF personnel continue to work to mitigate the incident.”

 

How this crash differs from the East Palestine wreck

 

The fiery derailment in Raymond happened almost two months after a Norfolk Southern train carrying hazardous chemicals derailed in East Palestine, Ohio.

That disaster ignited a dayslong inferno, spewed poisonous fumes into the air and killed thousands of fish. It also left East Palestine residents wondering if a variety of health problems since the derailment are liked to the wreck.

Both freight trains were carrying highly flammable and potentially toxic chemicals, such as vinyl chloride in Ohio and ethanol in Minnesota.

Preliminary information from Minnesota suggests 14 of the train’s 40 cars were carrying hazardous material, “including ethanol, which was released — leading to a fire,” US Transportation Secretary Pete Buttigieg told CNN Thursday.

In addition to ethanol, the train was carrying mixed freight including corn syrup, said Lena Kent, general director of public affairs for BNSF Railway.

Ethanol can explode when mixed with vapor and air. Ethanol exposure can lead to coughing, dizziness, the feeling of burning eyes, drowsiness and unconsciousness.

But there are differences between the chemicals on board the trains in Minnesota and Ohio, says Purdue University professor Andrew Whelton.

“Ethanol, like many chemicals, can be toxic if inhaled or comes into contact with skin or is ingested. But it requires a certain concentration to be a health hazard,” said Whelton, an expert in environmental chemistry and water quality.

Ethanol is highly soluble in water, meaning it will be relatively easy to dilute. “Dilution is one way to reduce the risk” of health issues from any water that may be contaminated with ethanol, Whelton said.

By contrast, the chemicals released in the Ohio train wreck “are generally heavier and less soluble in water,” Whelton said. “They sunk to the bottom of the creek and stayed. They didn’t flush away there.”

But it’s still not clear what may have been mixed with the ethanol on the train that derailed in Minnesota. While ethanol is a single compound, there are different blends of ethanol that may have different additives in them and could change the health risk, Whelton said.

 

A loud crash and a chemical stench

 

Brittney Phelps and her family were startled by a knock on their door at 1:30 a.m. It was a first responder going door to door telling residents to flee as a precaution.

“I heard a loud crash but didn’t think anything of it ’til ambulances were outside the house,” Phelps said.

She soon smelled the stench of ethanol and saw the wrecked train cars and large fire, Phelps told CNN.

The Minnesota Department of Transportation closed a nearby highway due to the derailment and blaze, the fire department said. The main railroad track is blocked, and an estimated time for reopening the line was not available.

The cause of the derailment is under investigation. A team from the National Transportation Safety Board is expected to arrive at the site Thursday afternoon, the NTSB said.
