The Hide-Away Storm Shelter was tested at the Texas Tech University Wind Science & Engineering Research Center (WiSE) to withstand Debris Impact per the design criteria of the ICC 500 "ICC/NSSA Standard For The Design and Construction of Storm Shelters", FEMA 320 "Taking Shelter From the Storm: Building a Safe Room For Your Home or Small Business", and FEMA 361 "Design and Construction Guidance for Community Safe Rooms" Guidelines. The test included multiple impacts by a 15 lb. wood 2"x4" propelled at 100 mph for horizontal impacts as produced by a missile propelled horizontally by a 250 mph ground speed tornado. The maximum resultant deflection imposed on the Hide-Away Storm Shelter was a 3/4 inch deflection. The testing criteria allows a maximum deflection of 3 inches.This test was conducted at the WiSE Facility by Mr. Larry Tanner, P.E., Research Associate Manager, Debris Impact Test Facility on April 5, 2013.
