Storm Shelter Testing
& Approval
On September 27, 2004, tests were
conducted on SI Precast's below ground storm shelter
door assembly in the Debris Impact Facility at Texas
Tech University. Tests were consistent with
FEMA 320 (Taking Shelter from the Storm) guidelines
requiring shelter doors resist a 15 pound missile
propelled at 100 m.p.h. The missile speed
correlates to the missile being propelled by a 250
m.p.h. ground speed tornado.
SI Precast's shelter door passed the
test and received approval from the Wind Engineering
Research Center at Texas Tech University.
