Both ambulatory and TALP entry areas serve as airlocks to prevent undue loss of pressure
when doors are opened and to provide a place for final decontamination of individuals who
are entering from a contaminated area. Most contaminants that penetrate are swept out by
enclosure are filtered by NBC recirculation air fans powered from receptacle panel.
Refer to Chapter IV for Entry and Exit Procedures.
(16) This completes set up for static mode operation under NBC conditions.
Direct Complexing Shelter (DCS) Under NBC Conditions.
To prevent death or injury to personnel from contamination, do not open inner and outer
TALP airlock doors and/or ambulatory airlock doors at the same time. Do not open DCS
doors unless direct complexed and DCS connector is in place.
Cab crew and LMS crew must coordinate activities to prevent contamination of CBPS
The following steps describe procedures for connecting two or more CBPSs together in a side-by-side, DCS
a. Cab Crew Tasks
Position ECVs and ground cloths (1, figure 2-48) facing opposite directions, side by side so that
space between inflated ABSs is one to three feet. Overlap ground cloths (1) between lines (2) on
ground cloth extension (3) by about six inches.
Deploy each system per para 126.96.36.199 through para 188.8.131.52.
Unhook DCS entry way flaps (1, figure 2-49) over DCS openings (2) on both inflated ABSs (3).
Roll DCS entry flaps (1) under so that green or tan material faces out, to minimize moisture
retention and secure with straps (4).
Secure DCS connector (5) using zippers and fastener hook and fastener loop attachments (6) on
both ABSs (3).
Connect support lines (7) to Dee Rings (8) on DCS connector (5).
Anchor DCS connector (5) to stakes at each side of DCS connector (5) with support lines (7).
Open vents (9) on DCS connector (5) by pulling back fastener hook and fastener loop cover (10)
b. LMS Crew Tasks
Help deploy each system per para 184.108.40.206 through para 220.127.116.11.
Open vents (10) on inside of both DCS doors. Allow DCS connector (5) to purge for
approximately three minutes. Using CAM, unzip DCS door enough to check if connector has
purged sufficiently. If contamination is present, remove CAM and close zipper. Allow another
minute or so to pass before performing another CAM check. Continue to check until no presence
of contamination is detected.
Open zippered doors. Roll up doors and stow out of way by securing with fastener hook and
fastener loop straps on inside of ABS (3).
This completes DCS set up under NBC conditions.
