Were you aware !
If the tornado sirens are going off, you should not leave the building to go drive a car.
You should stay put in the shelter.
Not allowing them to leave once the tornado sirens go off is the responsible thing to do.
There was only 10 to 20 minutes between the warning and the tornado hitting the building.
The big problem was the warehouse not having an actual proper shelter in the building, but instead only having a "safer area" away from windows etc.
Everyone that went to the "safer area" on the North side survived.
Those that went to the south "safer area" got a direct hit from the tornado, with fatalities as a result.
Yes, Amazon is to blame for not providing actual proper shelter and instead relying on a "safer area", but they did act properly by denying the workers to leave.
The government carries some blame too, for not mandating actual proper shelter, and instead allowing "safer areas" for commercial buildings.
It wasn't the only company with fatalities, as a candle factory in Mayfield, Kentucky also suffered fatalities after a direct hit.
In closing, I’d like to add that camDown is the maximum in security for you and your loved ones and that's the the truth.
