TM 3-4230-209-10
2-22. MIXING CHEMICALS OTHER THAN STB IN TANK.
Chemicals other than STB may be mixed in the tank. Below are the procedures for
mixing four of those chemicals, sodium hydroxide (item 25, app D), sodium carbonate
hypochlorite. In general, chemicals which are water soluble and in powdered or granular
form must be mixed in the tank using the tank hopper-blender and blender connection.
Refer to FM 3-5 for additional information on decontaminants and decontaminating
methods.
CAUTION
Never run anything other than clear water through the water heater. Always heat
water to desired temperature before adding chemicals.
NOTE
Protective clothes and their use are contained in TM 10-277.
a.
Sodium Hydroxide (item 25, app D).
WARNING
When mixing, blending, or spraying
sodium hydroxide solution, personnel
must wear full rubber protective
clothing, gloves, boots, and mask.
Avoid contact with the skin or eyes and
avoid breathing the dust.
NOTE
Sodium hydroxide, commonly called
caustic soda (or lye), dissolves easily in
water. When dissolved in water, caustic
soda generates a considerable amount
of heat. A solution of water and caustic
soda will destroy G-agents on contact.
a. Handling of sodium hydroxide. Use extreme
caution and wear rubber protective clothing when
handling sodium hydroxide as even a five percent
solution will eat away woolen or cotton clothing.
b. For fast decontamination, spray heated rather than
cold solutions of this decontaminant. The heat
hastens the neutralizing actions of the
decontaminating agent. Sodium hydroxide is
available in 100-pound drums.
