The Occupational Safety and Health Administration (OSHA) was notified of a deadly collapse that impacted an Amazon (AMZN  ) warehouse in Edwardsville, Illinois this past Friday as a tornado hit the warehouse, causing total destruction to the entire area.

A total of six employees were killed and one suffered from injuries, but 45 workers were rescued, according to Governor J.B. Pritzker at a press conference this past Saturday. At the press conference, police chief Mike Fillback informed reporters that police officers had difficulty with discovering "how many people we actually had at that facility at the time because it's not a set staff," quoted by CNBC.

Management from Amazon was there to try to make a list of those who could be counted, but they stated that it was still challenging to tell the exact number of individuals who remained within the building. One agency spokesperson, Scott Allen, revealed that the OSHA had set up compliance officers to be on the scene ever since Saturday in order to help with the after effects that the tornado had caused, which had ultimately led to its collapse.

"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," Allen said in a statement, quoted by CNBC.

Regarding the disaster, Amazon spokesperson Kelly Nantel stated in an email to CNBC: "OSHA investigates all workplace fatalities and we are supporting them."

This tornado was one of thirty that left such destructive patterns throughout a variety of states, especially Kentucky, which is where over 60 individuals were reported dead. Amazon has reported that it was working toward inspecting the incident as well as to offer support for recovery, which would involve helping with local relief efforts in Edwardsville.
