FDNY Selects RST’s Demron™ For Protective Gear

Miami-based Radiation Shield Technologies (RST) — developer of Demron™ radiation-blocking products
that provide multi-hazard protection from heat as well as all nuclear, biological, chemical, bomb
and ballistic threats — has announced it will provide its Demron™ personal-protection armor to the
New York City Fire Department (FDNY) to outfit its firefighters as part of its chemical protective
clothing upgrade program.

Demron comprises a radiopaque nanopolymeric compound fused between layers of fabric and is
offered in two product lines including Demron-W for full-body suits, vests and blankets for
first-responder and military applications; and Demron-M X-ray vests, aprons and other products for
medical applications.

FDNY’s Hazardous Materials Company 1 team is utilizing the Demron Two-Ply Radiation Torso
Vest, Demron-W High Energy Nuclear/Ballistic IED RDD RED Shield, and Crew Protection Blanket —
technologies that, according to RST, maximize safety while minimizing the time, manpower and
resources needed to respond to potential emergencies. The vest, which may be worn under most hazmat
suits to protect vital organs, the thyroid and the groin, has been tested by the U.S. Department of
Energy and proven to shield against X-ray and low-energy gamma emissions as well as high- and
low-energy beta and alpha particles. The shield, a flame- and acid-resistant blanket that helps
contain blasts and high-energy radiation sources, has been tested and proven by Street, Md.-based
H.P. White Laboratory Inc. to offer Level IIIA ballistic protection and the highest fragmentation
protection. The blanket, which RST custom-created for FDNY, provides first responders with total
nuclear shielding and also may be used to transport radiation victims without exposing others to
