Luckily no one was hurt in the Metrodome collapse on Sunday. But imagine if the Viking-Giants game had been in progress. With a capacity of 64,000 fans, that would have been a disaster.
Think about it: According to the University of Minnesota, two feet of snow weighs about 10 lbs. per square foot. That works out to 218 tons of snow per acre. The Metrodome roof is 9 acres, so that comes to 1,960 tons, or almost 4 million pounds of snow. That’s a lot of weight.
One would hope that the Vikings have this all figured out and would never let fans in during a blizzard. And they do have some experience to go by. According to The Christian Science Monitor , this is the 5th time the roof has collapsed. Maybe inflatable roofs for structures holding tens of thousands of people are not the best idea…
Events like this are always a good opportunity to evaluate workplace safety for our own businesses. Take the opportunity right now and go through a mental checklist of your facility. Any cracked walkways, sharp file cabinet corners, loose carpeting, etc? You don’t need 4 million pounds of snow to cause a safety hazard! Write down any items that spring to mind and check them out today.
