The Occupational Health and Safety Administration launched an investigation into an Amazon delivery station in Edwardsville, Illinois, that collapsed when hit by a tornado.

“OSHA has six months to complete its investigation, issue citations, and propose monetary penalties if violations of workplace safety and/or health regulations are found," agency spokesman Scott Allen told the Washington Examiner.

OSHA said it would not provide more information until it completes its investigation.

A tornado from the weekend storm hit the facility, killing six people and leaving one person hospitalized with serious injuries, according to the city.

Everyone who reported being on the property has now been accounted for, with 45 people being rescued from the facility, according to Illinois Gov. J.B. Pritzker.

The girlfriend of one of the victims told the New York Post her boyfriend who died in the facility was told he could not leave until the storm passed. When the company got a tornado warning, it required its workers to get into a designated shelter.

Amazon was alerted about the tornadoes between 8:06 and 8:16 p.m., and the tornado struck the building at 8:27 p.m., ABC News reported. The company told the Washington Examiner it supports the OSHA inquiry.

“OSHA investigates all workplace fatalities and we are supporting them,” said Amazon spokeswoman Kelly Nantel in a statement to the Washington Examiner.

The company also announced it would donate $1 million to the Edwardsville Community Foundation, according to KMOX.
