risk to unprotected soldiers.
These levels differ based on the type of
Negligible risk levels for chemical and biological
contamination will cause no more than 5 percent casualties among crews
working within 1 meter of contaminated surfaces for 12 continuous hours.
Negligible risk levels for radiological contamination will cause no more
than 2.5 percent nuisance effect, such as headaches and nausea.
The measurement of negligible risk levels has been specified for
radiological contamination at 0.33 cGy per hour measured 1 inch from the
Levels of chemical and biological contamination are not readily
measurable with currently fielded equipment.
detectable while holding detection equipment 1 inch from the surface should
be considered in excess of negligible risk levels.
contamination is suspected, then consider the contamination above negligible
responsibility for Thorough Decontamination.
The decontamination platoon
sets up and runs Detailed Equipment Decontamination (DED) (Figure 4-1). The
contaminated company receives guidance from the decontamination platoon
leader for setting up and operating the Detailed Troop Decontamination (DTD)
and instructions on clearing the Detailed Troop Decon Site.
decontamination platoon leader ensures the contaminated unit completes the
required actions in the predecontamination staging area before beginning
Detailed Troop or Detailed Equipment Decontamination.
A total of 13 soldiers from the contaminated company are required for
efficient operation. This includes 5 personnel identified to set up and run
Detailed Troop Decontamination, 5 detail soldiers, company NBC NCO, medic,
and supply NCO.
The contaminated company identifies a senior NCO to
supervise the entire technique.
One person is specifically identified to
maintain containers, the shuffle pit, and restore expendable supplies.
Ensure all individual and unit weapons are cleared and on "safe" before
entering decontamination site.
Set up a decontamination line as shown in
Distance between stations should be at least 3 meters to
prevent cross-contamination between stations.
Position alarms upwind of site operation. Use Buddy System to remove MOPP
Gear. Make every attempt to use hot, soapy water where it is specified. If
hot water is not available, use cool, soapy water but scrub longer.
