MAINTENANCE INSTRUCTIONS
32. Operator Maintenance
a.
It is the operator's (user's) responsibility-
(1) To keep the kit dry (the kit is not waterproof).
(2) To request the organization supply activity to initiate a requisition for a replacement kit in a timely manner
to insure that a usable kit is always available (paragraph 33). Exception date should be cited on the requisition, i.e.,
"Condition Code A Assets Only," to prevent receipts of kits with unacceptable remaining useful life.
(3) To examine the red-band and green-band detector tubes (without regard to detector kit discard date) to
determine whether they are in usable condition.
b. A red-band tube is in usable condition when the impregnated silica gel is colorless or light pink. Discard red-
band tubes when the impregnated silica gel is blue or green. (See instruction cards for color.)
c. A green-band tube is in usable condition when the impregnated silica gel is yellow or light tan. Discard green-
band tubes when the impregnated silica gel is brown or green. (See instruction cards for color.)
33. Organizational Maintenance
a. It is the responsibility of the organization to maintain a usable kit at all times and to store the kit when not in
use. A usable kit is one in which-
(1) The discard date of the kit (as stamped on out- side of the carrier) has not expired.
(2) There are sufficient components to perform at least five complete series of each test (para 22 through 30).
(3) The aspirator bulb assembly is functioning pro- perly.
b. Check the aspirator bulb at least semiannually. Insert the end of a sealed detector tube (end unbroken) in the
aspirator bulb adapter and compress the bulb holding the valve end up. The bulb should require at least 10 seconds to
reinflate after the bulb has been released. If the bulb reinflates in less than 10 seconds, it leaks. To replace the bulb
(NSN 6640-00-630-79659
