Two chemical, biological, radiological, nuclear defense specialists ensure gas masks are properly fitted prior to leak, seal, package and decontamination training April 21 at the gas chamber on Camp Hansen, Okinawa. The CBRN defense specialists assisted in familiarizing explosive ordnance disposal technicians with decontamination procedures following the leak, seal, package process used to mitigate CBRN-related hazards. The EOD technicians and CBRN defense specialists used protective equipment to perform general decontamination of the affected area and prepare the leaking ordnance for safe containment and transport before completing the decontamination process. The training instilled the Marines’ confidence in their safety equipment and procedures used to mitigate CBRN-related hazards. The Marines are with 9th Engineer Support Battalion, and Marine Logistics Group Headquarters Regiment, 3rd MLG, III Marine Expeditionary Force. - Two chemical, biological, radiological, nuclear defense specialists ensure gas masks are properly fitted prior to leak, seal, package and decontamination training April 21 at the gas chamber on Camp Hansen, Okinawa.
