in a confined area without adequate ventilation.
d) Because of corrosion problems, water in
Department of Transportation (DOT) certified tanks is limited
to 0.5 pounds per million cubic feet (8 kg/10 6 m3).

Fuel Additives
2.3.9.1
Fuel System Icing Inhibitor (FSII), High Flash,
[MIL-DTL-85470] (diethylene glycol monomethyl ether (DIEGME))
a) Used in aviation turbine fuels to prevent the
formation of ice crystals from entrapped water in the fuel at
freezing temperatures. In addition, it has good biocidal
properties, preventing growth of microorganisms in the fuel.
b) Avoid water entry/bottoms in storage tanks
because the additive will dissolve in the water, reducing the
concentration of additives left in the fuel.
