That is for the DS2 operator decontamination sprayer. The thing LOOKS like a fire extinguisher but it is camouflaged, not red. DS2 will burn easily, especially if you spray it on dry STB (as if anyone has DS2 or STB )

Why nitrogen? Because CO2 reacts with DS2. Why a cartridge? Because DS2 comes in 5 gallon cans. The decon units were only filled if expected to go into a possible area. It is used on the operator-contacted areas and only under MOPP level 4 which meant you didn't have to worry about it on the skin, the personal decon wipes are used for that.

These are much higher pressure than CO2. Be careful.
