CHEMICAL BIOLOGICAL PROTECTIVE SHELTER (CBPS) SYSTEM
CBPS MISSION CONTAMINATION SCENARIOS.
A clean CBPS unit travels through a nuclear biological chemical (NBC) contaminated area and
deploys in a clean area.
A NBC contaminated CBPS unit strikes in a NBC contaminated area.
A clean CBPS unit is set up in a clean area in non-NBC mode and then exposed to a NBC attack.
The instructions of this presentation are specific to the CBPS. These instructions have three purposes. If
the CBPS becomes contaminated these procedures will:
a. Prevent the spread of contamination.
b. Ensure decontaminants used on the CBPS will not degrade the performance of any material
properties or mechanical operations.
Ensure that the decontamination can be carried out with the least effort and greatest
effectiveness. This appendix describes procedures for three levels of decontamination:
Immediate Decon (Non-CBPS Specific) - Immediately following a NBC attack or exposure, skin
decon should be performed using the skin decontaminating kit (SDK), followed by individual
equipment decon using the individual equipment decon kit (IEDK). Lastly, operators use the
on-board decon apparatus to decon surfaces that the users must come in contact with to operate
the equipment or perform maintenance.
Operational Decon (CBPS Specific) - This procedure includes a Mission Oriented Protective
Posture (MOPP) gear exchange when thorough decon cannot be done. Soldiers continue to wear
MOPP gear until thorough decon can be accomplished. Vehicle washdown should be performed
within 6 hours of being contaminated when the mission does not permit a thorough decon. This
process removes gross contamination and limits the spread of contamination.
Thorough Decon (CBPS Specific) - This detailed procedure requires the support of a battalion
decontamination unit and powered decontamination equipment with which decontaminants can
be applied to areas that are difficult to reach, atop and underneath the system. These
procedures are also conducted at designated decon sites which are predetermined by the decon
OPERATIONAL DECON ABSTRACT.
Operational decon enables the CBPS crew to continue the mission with very little delay. It may be required
once the CBPS has become contaminated with liquid or vapor agent, either in transport or while in
operation. The main purpose of operational decon is to prevent contamination from being transferred from
exterior surfaces to the interior NBC protected area of the LMS & ABS. Operational decon is necessary only
if there is contamination on the exterior shelter surfaces that must be touched by someone preparing to
enter the shelter, to perform maintenance, or to make the system ready for transport. Normally the
crewmen who ride in the LMS will turn on the system when the CBPS is to be erected in a contaminated
environment. Therefore, entries will normally be made only through the airlock using the prescribed
procedures for entry/exit in a contaminated environment as described in the operators manual (Chapter 4).
The transit cover and ground cloth are not made of agent-resistant materials. These items
should be used even if detection paper identifies them to be contaminated. Only discard at
the deliberate decon site as instructed.
