GD-6 Decontamination Agent

Transcription

1 GD-6 Decontaation Agent Highly efficient chemical decontaation agent fielded by NATO GD-6 the enhanced water-free chemical decontaation formulation for civilian and military applications from OWR After the success and fielding of GD-5 with NATO several years ago, development has taken place leading to the improved formulation of GD-6 GD-6 has been extensively tested by several renowned institutes and is fielded by NATO: NSN FOGBOOSTER using GD-6 In 2009 the Canadian Armed Forces chose GD-6 due to its water-free formulation for the detoxification of high-value equipment

2 GD-6 Decontaation agent Highly efficient chemical decontaation agent fielded by NATO GD-6 was developed and produced in Germany GD-6 has been developed and tested to standards higher than the recommended NATO Decontaation Triptych. Scientific experiments have been undertaken to proof the absolute detoxification capability of GD-6 and study the reaction kinetics when used with the highly toxic nerve agents Soman, VX and blister agent S-Mustard (HD). Within the performed experiments the evaluated GD-6 formulation was found to exhibit the expected capabilities and exceed demands. Remains fluid down to at least -20 C. Capability to easily dissolve chemical warfare agents Impressive absolute detoxification capacity of 1 : 1 to 3 : 1 (gram GD-6 : gram CWA). High to very high detoxification rates. At ambient temperature Soman was detoxified in less than 1 ute, VX in less than 3. and S-Mustard in less than 10 utes. Micro-droplet application of GD-6 According to the required demand, thin layers of GD-6 can be applied to sensitive surfaces like the inside of vehicles, ships, aircraft and infrastructure. The outside of vehicles and heavy equipment can be decontaated using low pressure applications to protect sensitive modules like sighting mechanism, heat image optics etc. OWR GmbH Oberschefflenzer Str Elztal-Rittersbach Germany phone: +49 (0) fax: +49 (0) welcome@owrgroup.com Subject to technical changes

Following Table 7 summarises computed periods of time to reach full decomposition of the VX and HD at elected operational temperatures. Calculations were performed taking into account the above-mentioned prepositions and computed activation parameters that characterise decomposition reactions in the GD-6A, see above on pages 12 and 14. Table 7 Predicted values of the respective rate constants, half-times, and times to attain full detoxification of the VX and HD Operational temperature, C Rate constant of the first order, s -1 VX Half-time of the reaction, Time to achieve full decomposition, Rate constant of the first order, s -1 HD Half-time of the reaction, Time to achieve full decomposition,

5 As it can be seen from Table 7 the VX agent may be fully detoxified at ambient temperature (20 C) within 3 utes while the HD in some 10 utes. By the ice point (0 C) the VX is detoxified in ca. ½ hr and the HD after some ¾ hr, which means an excellent reactivity. The GD was found to be so reactive that its decomposition reaction proceeds nearly immediately even at very low temperatures down to -20 C. 4 CONCLUSIONS AND RECOMMENDATIONS Within performed experiments the evaluated GD-6A formulation was found to exhibit tendency to form a super-freezing liquid down to at least -20 C. capability to dissolve at least 1 volume part of CWA in 9 volume parts of GD-6A easily. absolute detoxification capacity of 800 mg GD, 580 mg HD or 280 mg VX per 1 gram of the GD-6A. high to very high detoxification rates. At ambient temperature the GD was detoxified immediately in less than 1 ute, while the VX in less than 3 utes and HD in less than 10 utes. According to these excellent results it could be recommended to the Customer to evaluate efficiency of this formulation on samples of real materials as it is recommended by the NATO Decontaation Triptych. 16
