FEMA 320- Door for In-Residence and Small Business Safe Rooms:
Securall® StormSafe® Doors are constructed in accordance with Federal Emergency Management Agency (FEMA) recommended design specifications and independently tested at Texas Tech University's Wind Science and Engineering Research Center. The design is based on extensive research of the causes and effects of windstorm damage to buildings and should provide a high degree of occupant protection during extreme windstorms (tornadoes and hurricanes). A Securall® StormSafe® Door is a critical element when designing a safe room for protection against severe storms.
Strong tornadoes have resulted in loss of the floor framing, collapse of basement walls and death and injuries to individuals in the basement. By having a safe room in your home, you can protect your family and save the lives of those you care about.

FEMA 320 Doors: Securall is dedicated to provide doors and hardware that provide protection for a safe room. Since the door to the room can be the weakest portion, selecting and properly installing a door strong enough to withstand heavy impacts and winds is crucial for the safe room to be a true shelter. Our FEMA door meets the guidelines set forth in FEMA 320 standards and provides the safety necessary to construct a safe room using for 14- and 12-gauge steel panels. FEMA does not certify specific products for use, but securall have their doors tested to demonstrate that the FEMA criteria have been met. The National Storm Shelter Association (NSSA) provides approved product listings for safe room components or to verify vendor claims of standards compliance for tornado and hurricane safe rooms and components.
StormSafe® Door Pressure & Debris Impact Test at Texas Tech: Pressure and impact tests were conducted at Texas Tech University's Wind Science and Engineering Research Center. The test on FEMA 320/ICC-500, Model HD42x84-O-LH was consistent with the guidelines of FEMA 320 and ICC-500 (2008) Standard for "The Design and Construction of Storm Shelters" and the ICC-500 requirement that the pressure test load should include a safety factor of 1.2. This pressure relates to a 250 mph ground speed tornado and the door installed in Zones 4&5 per ASCE 7-05 for a corner zone with the negative pressures being greater than the positive pressures. The goal pressure is 2.19 psi which must be held for 10 seconds in accordance to ASTM E330. In accordance to FEMA 320, the residential shelter guideline, swinging door assemblies should resist a static pressure of 1.37-psi for a 5-second period. The tornado test criterion uses a 3 impacts of 15-lb. 2x4-in. wood board traveling horizontally at 100-mph, which corresponds to a 250-mph wind.
Test Results FEMA 320/ICC-500, Model HD42x84-O-LH door assembly passed 2.19 psi for 10 sec.(includes ICC-500,1.2 Safety Factor) & three impacts and is qualified to meet both the FEMA 320 and the ICC-500 standards of door pressures and impacts for doors in storm shelters.
All testing was in strict accordance to FEMA 320 (2008),ICC-500 (2008), and ASTM E330.
