STOCKPILE COMPONENTS AND THREAT

1. STOCKPILE COMPONENTSAND THREAT CA31

2. OBJECTIVE • Describe the types of munitions stored in your vicinity and the potential for an off-site release CA32

3. STOCKPILE COMPONENTS • Characterized by • form of munitions • type of agent • packaging and storage requirements • maintenance requirements • potential threat of accidental release CA33

4. TYPES OF MUNITIONS One-ton Containers Bombs Land mines Rockets Cartridges Projectiles (Spray Tanks not shown; not to scale) CA34

5. ROCKETS • All obsolete and declared hazardous waste • Contain approximately 10 lbs of GB or VX in extruded aluminum warheads • Warhead includes explosive charge (burster) and fuse to initiate charge • Solid propellant contained in a steel motor that is threaded onto warhead M55 rocket CA35

6. ROCKETS • Stored in fiberglass shipping and firing containers with aluminum ends • 15 shipping/firing containers per 1 pallet • Always stored in igloos pointing toward earth-covered concrete wall • In unlikely event of accidental ignition,rocket should not escape the igloo Rocket pallets inside storage igloo CA36

7. ROCKETS • No scheduled handling or maintenance since obsolete • Checked routinely for leakage • Checks made of interior of igloo and inside shipping and firing container • Any leakage discovered is promptly contained using approved overpacks M55 rocket CA37

8. ROCKETS • Army tests established that if 2 rockets exploded, 13 other rockets would leak forming an agent puddle • occurs inside igloo • no off-post liquid threat • low concentration of agent vapors likely to pass installation boundaries CA38

9. CARTRIDGES • 2 types • 1 fired from howitzer containing approximately 2 – 3 lbs of GB or HD • 1 fired from mortar containing approximately 6 lbs of HD or HT • Rarely, but sometimes, have all elements needed to be fired encased in fiberboard container • includes propellant, bursting charge, fuze • 2 fiberboard containers to 1 wooden box • 12 to 36 wooden boxes per 1 pallet GB cartridge CA39

10. CARTRIDGES • All cartridges stored in igloos • Normal maintenance includes rewarehousing, handling and inspecting for defects and leakage • if leakage detected, probably would be vapor for GB and liquid for HD and HT • effects would be confined to igloo • Army has determined if one cartridge explodes no other cartridge in igloo would detonate • no cartridges can spontaneously explode • external force such as fire or accident must occur to cause cartridge to explode CA40

11. PROJECTILES • Heavy, thick-walled metal shells of 1- or 2-piece construction • Filled with GB, VX, H, HD, or HT • between 2 and 14 lbs of chemical warfare agent • Most projectiles not fuzed • most projectiles do not have burster explosives loaded into shell • Propellant charge required for firing shipped, stored, and issued separately GB projectile CA41

12. PROJECTILES • Packaged 6 or 8 to 1 pallet • All stored in igloos • Normal maintenance includes rewarehousing, handling and inspecting for defects and leakage Illustration of a projectile pallet CA42

13. PROJECTILES • If leakage detected, probably would be vapor for GB and liquid for H, HD, HT, or VX • effects would be confined to igloo • Army has determined if one projectile explodes no other projectile in pallet or igloo would detonate • no projectiles can spontaneously explode • external force such as fire or accident must occur to cause projectile to explode CA43

14. MINES • Contains 10.5 lbs of liquid VX • Contains explosives used to burst mine open and spread its chemical warfare agent payload • 3 mines per 16-gallon, waterproof, metal drum • All mines stored in igloos • Normal maintenance handlingand inspecting for defects and leakage • leaks would be primarily around base of mine and in side fuze well VX land mine CA44

15. MINES • Leakage easily detected because of dissolved portions of packing supports and missing paint on mine body • Liquid and vapors confined to vapor-proof container • Army has determined if one mine explodes other mines in drum would detonate • mines cannot spontaneously explodes • external force such as fire or accident must occur to cause mine to explode Cut away of a land mine CA45

16. BOMBS • 3 types • Contain 105 to 350 lbs of GB • depending on type of bomb • No bombs stored with explosives • Bomb bodies are steel or aluminum alloy GB 500 lb bomb CA46

17. BOMBS • All bombs stored in igloos • Aluminum bomb packaged individually in vapor-proof container • Other two older steel body types usually stored 1 or 2 to 1 pallet unit GB 500 lb bomb CA47

18. BOMBS • Normal maintenance includes rewarehousing, handling and inspecting for defects and leakage • Leakage would probably be vapor seeping from welds on upper portion of bomb GB 500 lb bomb CA48

19. BOMBS • Since no explosives involved, worst possible event is a liquid spill of entire contents • has never happened • if it did, liquid confined to storage structure • if weak concentrations of vapors reached off-site, would likely be too weak to pose hazard to civilian population GB 500 lb bomb CA49

20. ONE-TON CONTAINERS • Industrial metal containers manufactured for storage of bulk liquids • No explosives involved • Capacity ranges from 1500 to 1800 lbs depending on chemical warfare agent stored One ton containers stored at Newport Chemical Depot, Newport, IN CA50

21. ONE-TON CONTAINERS • 2 valves located on 1 end of container • 6 plugs • 3 plugs evenly spaced on bulkhead ends • Valves and plugs made of brass or steel • Containers stored in igloos, metal storage buildings, oroutdoor storage yards • depending on chemical warfare agent and location One ton containers stored at Newport Chemical Depot, Newport, IN CA51

22. ONE-TON CONTAINERS • Normal maintenance includes painting of containers stored outside, replacing all brass valves and plugs with stainless steel ones, and inspecting for defects and leakage • Leakage would be from the plugs or valves • any liquid released would be confined in storage area Maintenance inspection of valves and plugsat Deseret Chemical Depot, Tooele, UT CA52

23. SPRAY TANKS • Contain 1365 lbs of liquid VX • Constructed of 1/8-in stainless steel • 1 tank overpacked to a large metal, vapor-proof, modified jet engine container Spray tank in overpack container CA53

24. SPRAY TANKS • Stored in igloos and metal storage buildings • Normal maintenance includes handling and inspecting for defects and leaks • Vapor leaks never detected • No liquid leakage has occurred • in unlikely event of liquid leaks, liquid would be confined to vapor-proof container CA54

25. LEAKING CHEMICAL WARFARE AGENT • Leaking liquid or vapor is controlled and contained until leaking item can be disposed of properly • leaker is sealed in approved container as soon as possible • if vapor-proof container leaking due to defective gasket, gasket is replaced • if gasket cannot be replaced,container is replaced • if no serviceable containersare available, item is overpackedin larger vapor-proof container or chemical warfare agent contents are transferred to another container Packing leaker in vapor-proof container CA55

26. LEAKING CHEMICAL WARFARE AGENT • Contamination promptly neutralized • Storage structures are sealed and equipped with air filters during leaker containerization operations • Rockets filled with GB cause greatest concern • due to design and large numbers • less than 1/10th of 1% of rockets have developed leaks • Army has developed 2 specially designed vapor-proof overpacks • leaking rockets have been stored in these leaker containers (overpacks) and monitored for further leakage with excellent results CA56
