The 2015 edition of the International Building Code (IBC) includes requirements for storm shelters, typically associated with tornado- and hurricane-prone areas where high winds occur. These shelters can be detached from a building or contained as safe rooms within a building to provide a safe refuge for people. Requirements for storm shelter testing in hurricane-prone areas differ significantly from the requirements for shelters in tornado-prone areas. This document focuses on the use of impact glazing in the latter.
