This video shows an entry door used in a Safe Shed, Inc storm shelter being tested for stability from flying debris typical of tornadoes. The testing consist of three impacts at key areas of the door using a 15 pound board being shot from a wind cannon at speeds of 100 mph. The test is designed to check for stress failures on key components of the door. This door design successfully passed the testing required by the National Storm Shelter Association.
