d. Calcium Hypochlorite (item 6, app D).
WARNING
Calcium hypochlorite will destroy clothing, has a toxic vapor, and will burn the
skin.
CAUTION
Calcium hypochlorite (HTH) is highly corrosive. Its use with the decontaminat-
ing apparatus may shorten its useful life. HTH should not be used except in an
emergency when STB is not available.
NOTE
Calcium hypochlorite is commonly known as high-test hypochlorite
(HTH) or high-test bleach (HTB). This compound contains a higher per-
centage of chlorine than STB decontaminating agent and is more corro-
sive. Crew members must wear a full set of rubber protective clothing
when handling calcium hypochlorite. Hot or cold calcium hypochlorite is
effective on the same agents as STB decontaminating agent. Clean
equipment thoroughly after it has been used to spray calcium hypochlor-
ite; flush with large amounts of water. Calcium hypochlorite is available
in both 25 pound and 100 pound drums.
Protective clothes and their use are contained in TM 10-277.
