If there is no indication of agent, the patient's mask is removed and sealed in an M1A1
waterproofing bag. The patient is then brought into the CBPS. As the patient is being removed from
the inside airlock, another ten-second CAM/ICAM check is made around the wound.
d. Any time during the CAM/ICAM check, a positive reading indicates the patient must wait longer in
the airlock. However, the physician determines whether to put on masks and bring the patient into
the CBPS or to wait for more purging.
4.15 MONITORING AMBULATORY PATIENTS IN AIRLOCK.
a. The operator in the CBPS performs the first part of the CAM/ICAM check while the soldier is in the
airlock. The operator extends the CAM/ICAM in the airlock to within 1/2 inch of the soldier's
clothing. He holds it there through a count of ten seconds, then withdraws it and reads the display.
The operator then switches to the second mode and repeats the process. This airlock check can be
done at any time before the soldier unmasks in the airlock.
b. If the reading is zero bars in both G and H modes, the airlock purge period can be halted without
waiting the full duration. If the CAM/ICAM detects contamination in the airlock, the person will be
directed to wait the full five minutes.
If after five minutes, the CAM/ICAM is still reading more than zero bars, the operator will tell the
entering soldier either to wait another five minutes in the airlock or to remove his fatigue clothing
and combat boots, place them in a trash bag, mark the bag, and leave the bag in the airlock.
d. If the CAM/ICAM response is negative, the soldier will then remove his mask, bag it, and enter the
As soon as the soldier steps into the CBPS, the CAM/ICAM operator will again check for absorbed
vapors on the clothing and hair. With the CAM/ICAM in the G mode, the operator places the tip of
the CAM/ICAM 1/2 inch from any part of the soldier's clothing or hair. The operator then switches to
the H mode and repeats. If contamination is found, the soldier is directed to either remove and bag
his/her garments, go back to the airlock to remove them or to put a clean overgarment over his/her
4.16 PASSING SUPPLIES AND EQUIPMENT INTO CBPS.
a. Supplies and equipment are passed into the CBPS through either of the airlocks when operating in a
contaminated environment. The following are procedures for doing so.
All supplies and equipment that are sent into the CBPS should be protected with
contamination-avoidance covers during transportation and storage. They should also be kept in
their outer packaging until they are ready to be passed into the airlock.
All items that enter the CBPS have to first be checked for liquid contamination with M8
Items are then placed into one of the airlocks. If possible, the outer packaging is removed as
they are passed into the airlock (e.g., removing meal rations from their outer box and passing
them in as individual meals).
The CAM/ICAM operator in the ABS extends the CAM/ICAM into the airlock, placing the tip of
the CAM/ICAM 1/2 inch away the supplies or equipment. The CAM/ICAM operator tests
samples in the G mode then on the H mode.
If no contamination is detected, the supplies or equipment are brought into the CBPS.
b. Waste materials are sent out through the airlocks. Bagged waste can be placed in either the
ambulatory airlock or on a litter in the tunnel airlock.
