031-503-3004 (SL2) - Supervise the Crossing of a Contaminated Area

Standards: Supervised a unit crossing or passing through a nuclear, biological, or chemical contaminated area without producing additional casualties or spreading contamination.

Conditions: You receive orders to cross a nuclear, biological, or chemical contaminated area. Given a unit with mission-oriented protection posture (MOPP) gear; organic decontamination equipment (such as M13 decontaminating apparatus portable (DAP) and individual decontaminating kits), chemical (such as M256 chemical agent detector kit, M8 chemical agent detector paper, and M9 chemical detector tape) and radiological (such as IM174-series radiation, detection, indication, and computation [RADIAC] meter, AN/UDR-13 and AN/VDR-2 RADIAC sets, and IM93 dosimeter) detection and/or warning devices; shielding material (such as sandbags); and a defined NBC contaminated area.

Standards: Supervised a unit crossing or passing through a nuclear, biological, or chemical contaminated area without producing additional casualties or spreading contamination.

Performance Steps

1.   Supervise a unit crossing a nuclear contaminated area.

a. Before crossing-

(1)  Provide shielding for personnel. Use vehicles if possible. Place sandbags on the floor and sides of all vehicles (within reason for nonarmored vehicles).

(2)  Tell vehicle operators to close all doors, windows, hatches, and vents on their vehicles.

(3)  Have soldiers cover all exposed skin by rolling down their sleeves and buttoning their collars. Ensure that they wear handkerchiefs or similar cloths over their noses and mouths to keep from breathing radioactive dirt or dust.

(4)  Select the shortest possible route that would cause the least contamination and permit the fastest travel based on mission, enemy, terrain, troops, time available, and civilian considerations (METT-TC).

(5)  Ensure that IM93 dosimeters are available and charged to zero.

(6)  Ensure that AN/UDR-13 and AN/VDR-2 RADIAC sets are available and operational.

(7)  Delay entry into the area as long as possible within the limits of the mission.

b. During crossing-

(1)  Perform continuous monitoring.

(2)  Have the monitors watch the dose rate on the AN/UDR-13 or AN/VDR-2 RADIAC set. Instruct them to keep you informed. Ensure that the commander's turn-back dose rate is not exceeded without approval.

(3)  Have all personnel with dosimeters check them often to ensure that the commander's turn-back dose is not exceeded without approval.

(4)  Move through the area as quickly as possible. Do not forget safety or security.

(5)  Ensure that vehicles are far enough apart during movement to minimize dust. Consider the tactical situation, the command, and the control when spacing the vehicles.

c. After crossing-

(1)  Have personnel check themselves and their equipment for contamination. Have everyone brush the dust from his or her clothing.

(2)  Determine if decontamination is required.

2.   Supervise a unit crossing a chemical contaminated area.

a. Before crossing-

(1)  Select the shortest possible route that would cause the least contamination and allow the fastest travel based on METT-TC.

(2)  Tell vehicle operators to close all doors, windows, hatches, and vents on their vehicles.

(3)  Assume MOPP 4.

(4)  Have soldiers attach M9 detector paper to their clothing and equipment.

b. During crossing-

(1)  Ensure that vehicles are far enough apart during movement to minimize dust. Consider the tactical situation, the command, and the control when spacing vehicles.

(2)  Move through the area as quickly as possible. Do not forget safety or security. Continuously monitor personnel for chemical agent symptoms, and give first aid as required.

(3)  Ensure that soldiers avoid touching anything in the area if possible.

(4)  Monitor personnel closely for symptoms of heat stress, and minimize excessive heat buildup.

c. After crossing-

(1)  Continue to monitor soldiers for chemical agent symptoms, and give first aid as required.

(2)  Have soldiers use detector paper to check themselves and their equipment for contamination.

(3)  Have soldiers use their decontaminating kits to decontaminate any contaminated skin or personal equipment. Seek medical aid as required.

(4)  Have vehicle operators use available decontaminating equipment to decontaminate their vehicles, if required.

3.   Supervise a unit crossing a biological contaminated area.

a. Before crossing-

(1)  Select the shortest possible route that would cause the least contamination and allow the fastest travel based on METT-TC.

(2)  Tell vehicle operators to close all doors, windows, hatches, and vents on their vehicles.

(3)  Assume the appropriate MOPP level, as required.

b. During crossing-

(1)  Move through the area as quickly as possible. Do NOT forget safety or security.

(2)  Ensure that personnel do NOT touch anything in the area that can be avoided.

(3)  Ensure that vehicles are far enough apart during movement to minimize dust.  Consider the tactical situation, the command, and the control when spacing vehicles.

c. After crossing-

(1)  Decontaminate personnel and equipment by washing them thoroughly with hot, soapy water, if time and mission permit.

(2)  Do as many of the steps as possible for the types of contamination present in the area.

(3)  Seek medical aid if required.

Evaluation Preparation:

Setup: Evaluate this task during a field exercise or a normal training session. The contaminated area may have been marked with the appropriate markers, or a diagram may have been prepared showing the boundary of the contaminated area, the soldier's present location, and the desired direction of travel. Gather the necessary equipment and personnel to conduct the movement. Obtain, for training purposes, fictitious commander's operational exposure guidance (OEG) on the turn-back dose and the turn-back dose rate.

Note. Before conducting this task, ensure that soldiers have been trained on the following tasks: 031-503-2020, 031-503-2001, 031-503-2013, 031-503-1037, 031-503-1013, and 031-503-2023.

Brief Soldier: Tell the soldier to supervise the movement of a unit through a nuclear, biologically, or chemically contaminated area by performing the appropriate measures before, during, and after the movement through the area. Give the soldier an illustration, showing the boundary of the contaminated area, the soldier's present location, and desired direction of travel through the contaminated area.
