The Global Defender Blast Mitigation System allows technicians to mitigate and contain a variety of detonation and dispersion devices enabling a controlled evacuation of the area. Designed for rapid, remote, no-contact deployment, the system provides for superior operator safety and effectiveness.
The Global Defender significantly mitigates the effects of dispersal (Chemical, Biological, and Radiological) and Explosive threats up to 5 pounds. In addition to multiple explosive analyses, the system was evaluated by the US Department of Energy for Radiological Dispersal Device containment. The system fully contained 2 daily doses of Technetium-99 attached to a 1 pound binary explosive charge within a 20 feet radius as opposed to an unmitigated 1 daily dose contamination radius of 75 feet and the aerial dispersion of the agent.
Method of Operation
All systems use the patented foam enclosures. The enclosures, which are folded for easy storage and deployment, automatically unfold to cover the device as they are filled with foam. The enclosures are made from a synthetic material designed to expand and give way, as necessary, when the device is detonated. The expansion enables the system to suppress and contain the blast effect, fragmentation, and any dispersible agents that may be attached to the device. The enclosures are fabricated with a solid bottom to prevent the foam from contacting the device reducing the risk of inadvertent detonation and it allows the enclosure to be moved once it is filled without spilling the foam.
The systems are compatible with most tools available today including disrupters, counter-charges, and perforators among others. A deployed system provides operators at least four hours of mitigation before the foam begins to degrade. The thickness and density of the proprietary foam offers many benefits including extended time to address a mitigated device, suppression, containment of dispersible agents by capturing and containing the agent within its bubble structure suspending it for hours, and easier clean-up post blast since the foam remains intact. The foam is biodegradable allowing it to dissipate on its own with no required cleanup if it was not contaminated with any dispersible agent.
