will be able to
Recall the procedures for area decontamination
Identify the purpose of the decontamination
There are four levels of decontamination
emergency personnel decontamination, limited
operational decontamination, operationally complete
decontamination, and complete decontamination.
LEVELS OF DECONTAMINATION
Level 1Emergency personnel decontamina- tion.
decontamination necessary to save your life. It is your
responsibility. The primary purpose of emergency
personnel decontamination is to safeguard you in
protective gear that includes the following items:
However, if a chemical attack takes place before
you don all of the protective gear, you need to destroy,
neutralize, or remove the chemical agents from inside
your protective gear and from exposed skin area.
Personnel decontamination kits (M291) give you the
ability to decontaminate skin surfaces. The
cleansing/decontamination stations used for entering
and leaving the ships interior provide soap, detergent,
and shower facilities.
Level 2Limited operational decontamination.
decontamination necessary to let you, while in
protective clothing and/or masks, do your job with a
minimum risk of contact, pickup, and transfer of
chemical agent contamination. Initial contamination is
most likely to be on the upper-outer surfaces of
structures and equipment. Further contamination may
be picked up and/or transferred to noncontaminated
areas. The two types of contamination hazards are
1. Pickup hazards. A chemical agent on a surface
that is touched by an individual, contaminating
2. Transfer hazards. A chemical agent picked up,
transferred, and then deposited on an otherwise
decontamination is to destroy, neutralize, or remove
persistent chemical agents that are located on structures
and/or equipment in places where they constitute a
Level 3Operationally complete decontami-
nation. Operationally complete decontamination (also
known as full decontamination) is decontamination so
that the contamination of personnel, structures, and
equipment is reduced to a level that results in a
decontamination reduces contamination to the lowest
level possible. However, it should only be conducted
when there is a reasonable chance that work can be
performed without masks or gloves for limited periods,
and the ships mission can be completed without undue
hazards to personnel.
One hundred percent decontamination cant be
accomplished on each and every item suspected of
being contaminated. Level 3 decontamination isnt a
fixed level of decontamination. It depends on the ships
operating schedule and the urgency of the assigned
mission. Decontamination at sea or by ships personnel
will be of this type.
Level 4Complete decontamination. Complete
decontamination is a degree of decontamination where
