Although buried metal and metal masses are com This scenario presents technical challenges for both monly detected using geophysical sensors, it is currently not assessing and accessing the CWM in these large burial possible to determine if a filled chemical munition is buried sites. within a mass of metal debris using geophysical sensors.

... chemical detector dogs have been demonstrated to have a Some of the new materials being developed that show detection capability "three to five orders of magnitude greater promise for monitoring chemical agents include fluorescent than the current best instrument detection capability."6 The indicator detectors, surface-enhanced Raman biosensing, and committee also found that England has plans to conduct tests porous silicon technologies.A fluorescent indicator selective at the Porton Down facility to determine the effectiveness of for electrophilic phosphates has been developed (Zhang and chemical agent detector dogs.7 Swager, 2003)

... This site consists of two very large by private companies to support advances in manufacturburial pits expected to contain between 300,000 and 400,000 ing processes.12 Much of this technology is applicable to individual chemical munitions. the development of robotic systems for use on large CWM For this project, the Japanese are designing a remotely burial sites.13 operated and automated excavation system consisting of As a result, the best solution to accessing CWM in large excavation robots, a device to remove attached soil using burial sites may be a combination of manual removal using pressurized air, and an automated transportation system that trained technicians and, when the risk is unacceptable, will take the removed CWM through a series of cleaning and removal by a suite of mobile robotic systems specially develassessment stations and then finally to a packing station and oped to perform specific high-hazard tasks as needed.

... The outer tent, measuring approximately 13 ft × 10 ft × 8 ft tall, is placed over the munition. The inner tent, 7 ft in diameter at the base and tapering to 4 ft at the top, will be Large Item Transportable Access and placed inside the outer tent and directly over the explosive Neutralization System/MonicaTM device.
