031-503-3010 (SL2) - Supervise the Employment of Nuclear, Biological, and Chemical Markers
Standards: Supervised the employment of NBC markers. Ensured that the appropriate marker was selected, the required information was recorded on the marker, and the marker was properly emplaced. There is no change in standards if this task is performed in MOPP 4.

1.   Supervise the employment of NBC markers for nuclear contamination.

a. Ensure that markers are placed at the location where a dose rate of one centigray per hour (cGy/hr) or more was measured.

b. Ensure that all information is printed on the front side of the marker so the word "ATOM" is facing toward you in an upright position. Information should include—

(1)  The dose rate in cGy/hr.

(2)  The date and time (local or Zulu, state which) of the detonation. (If the date and time are not known, print "UNKNOWN.")

(3)  The date and time (local or Zulu, state which) of the reading.

c. Ensure that markers are positioned so they can be easily seen and the recorded information faces away from the area of contamination.

(1)  Ensure that markers are attached to objects, such as trees or poles, so they will be easily visible from all probable routes through the contaminated area.

(2)  Ensure that each marker is placed so the next one can be seen from the one previously emplaced.

2.   Supervise the employment of NBC markers for biological contamination.

a. Ensure that all information is printed on the front side of the marker so the word "BIO" is facing toward you in an upright position. Information should include—

(1)  The type of agent detected. If unknown, print the word "UNKNOWN."

(2)  The date and time (local or Zulu, state which) of detonation (place beneath the date of detection).

b. Ensure that markers are positioned so they can be easily seen and the recorded information faces away from the area of contamination.

(1)  Ensure that markers are attached to objects (such as trees or poles) so they will be easily visible from all probable routes through the contaminated area.

(2)  Ensure that each marker is placed so the next one can be seen from the one previously emplaced.

3.   Supervise the employment of NBC markers for chemical contamination.

a. Ensure that all information is printed on the front side of the marker so the word "GAS" is facing toward you in an upright position. Information should include—

(1)  The type of agent detected. If unknown, print the word "UNKNOWN."

(2)  The date and time (local or Zulu, state which) of detonation (place beneath the type of agent detected).

b. Ensure that markers are positioned so they can be easily seen and the recorded information faces away from the area of contamination.

(1)  Ensure that markers are attached to objects, such as trees or poles, so they will be easily visible from all probable routes through the contaminated area.

(2)  Ensure that each marker is placed so the next one can be seen from the one previously emplaced.
