6.3 HOW TO TAKE OFF A CONTAMINATED CBRN PROTECTIVE ONE PIECE
UNDERGARMENT (DOFFING)
ATTENTION
While taking off the CBRN protective one piece
undergarment, the assistance of a second person
wearing protection equipment (respirator
and filter canister, protective gloves and body
protection equipment) is necessary.
Exposure to chemical warfare agents when wearing the one piece un-
dergarment requires special doffing procedures.The outer garment
should be assessed for liquid chemical warfare agent contamination
using approved procedures.
When taking off contaminated CBRN protective one piece undergar-
ment the following sequence is recommended:
1. Doff the top part of the outer garment. If butyl gloves are worn, do not
remove the butyl gloves. If the outer garment is a coverall instead
of a separate jacket and trousers, doff the top portion of the outer gar-
ment by rolling it out and down toward the waist so that the inner surfa-
ce instead of the outer surface is exposed as the garment is rolled down.
2. Doff the lower portion of the outer garment by rolling it in the same
way down to the ankles. If protective socks and combat boots are worn,
doff the combat boots but not the socks with the lower portion of the
outer garment.This should be accomplished by stepping out of the outer
garment and the combat boots at the same time. If butyl overboots are
worn instead of protective socks, remove only the butyl overboots when
removing the outer garment. The combat boots should be doffed later
with the one piece undergarment.
3. Doffing procedure for balaclava worn on top of the mask: Let the assi-
sting person cut open the balaclava starting from the neck at the center
back up to the butyl seal. Making sure that the mask is still correctly
placed on the head during the sequence. Balaclava worn underneath
the mask is not doffed at this stage of the procedure. Follow sequence 4
and see sequence 7 for the recommended doffing procedure.
4. Roll up the lower cuff part of the butyl and inner gloves that the as-
sisting person can cut the thumb loops and the lower sleeve part of the
one piece undergarment. Open the front zipper of the one piece under-
garment and doff the top while making fists with both hands to prevent
removal of the butyl gloves.
Observe the following strictly when taking off (doffing) a
contaminated CBRN protective one piece undergarment:
• Take off the equipment only out of the contaminated
area and only outside, however, if possible in a
protected, draught-free place which is, if possible,
covered with a roof.
• Observe the direction of the wind when taking off the
equipment.
• Avoid contact of the unprotected skin or underneath
worn body wear with the possibly contaminated
CBRN protective one piece undergarment.
Check for a tight fit
• of the undergarment sleeves on the protective gloves,
• of the undergarment trousers leg on the foot
protection
• of the undergarment hood on the head protection
(balaclava) on the respiratory mask
and adjust if deemed necessary.
After putting on the personal protection equipment,
get another person to check it for correct fit.
