INTRODUCTION AND PROCEDURES
To reduce the effects of contamination in a CBRN-contaminated environment, the CBT
should be operated with all windows, doors, and stowage boxes closed.
(CBRN) protective clothing without special tools or supporting equipment. Refer to FM 3-11.5 for information
on decontamination procedures. Specific procedures for the CBT are as follows:
Rubber sleeves and other rubber items, rope, and gaskets will absorb and retain chemical agents.
Replacement of these items is the recommended method of decontamination.
Lubricants or fluids may be present on the external surfaces of the CBT or its components due to leaks
or normal operation. These fluids will absorb CBRN agents. The preferred method of decontamination
is removal of these fluids using conventional decontamination methods in accordance with FM 3-11.5.
Continued decontamination of the external CBT surfaces with supertropical bleach (STB)/
decontamination solution number 2 (DS2) will degrade clear plastic (e.g., hydraulic fluid reservoir sight
glass) to the point where looking through it will become impossible. This problem will become more
evident for personnel wearing protective masks. Therefore, the use of STB or DS2 decontamination in
the area of clear plastic should be minimized. Clear plastic should be decontaminated with warm, soapy
External surfaces of the CBT and related equipment such as the remote control units that are marked
with painted or stamped lettering will not withstand repeated decontamination with STB or DS2 without
degradation of this lettering. Therefore, the recommended method of decontamination for these areas is
washing with warm, soapy water.
