Duct tape is used for sealing the bags of waste and clothing removed during entry processing. It is also used
to mark the clean litters and to differentiate between pails of 5% and 0.5% chlorine solutions.
4.10 PROTECTIVE PATIENT WRAPS (NSN 8465-01-079-9875).
This wrap is used for protection of patients when they leave the CBPS after treatment.
Section III. ENTRY AND EXIT PROCEDURES
4.11 LITTER PATIENT ENTRY PROCEDURES.
Each litter patient is decontaminated per FM 4-02.4 and FM 4-02.7 and is placed in the tunnel airlock for a
three-minute purging period. The timer on the airlock is set as the patient is placed in the airlock. The
patient is removed from the inside airlock once the timer indicates the three-minute period has elapsed and
the CAM/ICAMmonitoring, as described below, is completed.
4.12 AMBULATORY ENTRY PROCEDURES.
The first step in this procedure is to use M8 detector paper to determine if there is liquid contamination on
the soldier's outer garments, over boots or Nuclear, Biological and Chemical (NBC) gloves. If no liquid is
detected, the soldier enters the airlock in Mission Oriented Protective Posture (MOPP) gear. The soldier
removes all protective over garments in the airlock before proceeding into the CBPS. If the M8 detector
paper shows there is liquid agent present, the soldier removes outer garments, over boots and gloves outside
the airlock door per FM 3-11.4. The soldier then enters the airlock wearing the mask and hood. The steps in
this process are as follows:
4.12.1 Chemical Detection.
Use M8 detector paper to determine whether there is liquid agent on the outer clothing surfaces. Check the
following items in order:
a. Sides and soles of over boots.
b. Pant legs of over garment.
d. Shoulders and top of hood.
Any part of clothing that has been in contact with the ground or vegetation.
Any areas of clothing that appear wet.
4.12.2 Enter the Airlock.
If no liquid agent is detected, enter the airlock. Set timer for minimum of three minutes. If outer
door is opened during this purging, the dwell time must start over.
4.12.3 Remove MOPP Gear.
If liquid agent is detected, remove over garments, over boots and gloves outside the airlock per FM 3-
11.4 and discard them. Then enter the airlock. If CAM/ICAM monitoring reveals that the second
layer of clothing has been contaminated during entry, remove the clothing.
4.12.4 Remove Bags from Airlock.
Remove bagged clothing left in the airlock during the previous entry. Close the door and set the
4.12.5 Remove Outer Clothing in Airlock.
Remove over garment jacket, over garment trousers and over boots in order. Place them in a plastic
