Learning Objective Task: Learn the components of the ICAM, how to properly perform PMCS on the ICAM, and also how to operate the ICAM. Conditions: In a classroom environment, you are given an Improved Chemical Agent Monitor and a Technical Manual (TM) 3-6665-343-10. The order has been given to perform monitoring procedures for personnel and equipment in a potentially contaminated area. Standards: Operate the ICAM by performing monitoring procedures for personnel and equipment that includes preparing the Improved Chemical Agent Monitor for operation and movement.

Description and Purpose of ICAM The Improved Chemical Agent Monitor is an improvement over the currently fielded CAM. The modular design is less expensive to repair, requires less maintenance, and eliminates depot level repair now required for the CAM. The ICAM also starts up faster after prolonged storage and is more reliable. The ICAM is a hand held, soldier operated post attack device for monitoring chemical agent contamination on personnel and equipment. The ICAM is for use by personnel who are in full NBC protective posture. It is employed in both monitoring and survey missions and is primarily used to sort contaminated versus clean vehicles, equipment, and personnel. It reduces the burden and enhances the efficiency of the decontamination process. It does not require a specific Military occupational Specialty to operate and is used by a wide variety of units. Also, it is a Non Developmental Item (NDI).

Confidence Sample (8) The round cross-section end marked G contains nerve agent simulant. The ribbed end marked H contains mustard agent simulant. Tests the CAM for its ability to detect G and H. Housed in carrying harness pocket. Spare Nozzle Protective Cap Assembly (9). Sealed container housing a spare nozzle protective cap assembly. The nozzle protective cap assembly cleans air circulating inside the CAM Nozzle Protective Cap Assembly (10). Protects nozzle assembly and ensures that clean air is sampled when CAM is started. Nozzle Assembly (11). Chemical agent vapors are drawn in through this inlet for analysis by the CAM. Battery (12). Lithium-sulfur dioxide battery BA-5800/U powers the CAM Battery Cap Assembly (13). Provides access to the battery compartment and holds battery in place. Environmental Cap (14). Protects electrical connector and provides a temporary storage place for the nozzle protective cap assembly when the CAM is in operation. The environmental cap is not removed during operation unless the buzzer is attached. Buzzer (15). Attaches to electrical connector and provides an audible alarm when CAM displays two or more bars.

Detect Low levels of nerve (G, Vx) and mustard (HD, HN3) Capabilities The ICAM detects vapors of chemical agents by sensing molecular ions of specific mobilities (time of flight) and uses timing and microprocessor techniques to reject interferences. Detect Low levels of nerve (G, Vx) and mustard (HD, HN3) Not affected by common battlefield interferences Differentiates between nerve and mustard agents Is a lightweight and handheld monitor Instantaneous feedback of chemical hazard level Quickly determine contamination (or none) of front-line assets (people and equipment) Reduces the need for decontamination operations Real-time detection of nerve and blister agents

Preventative Maintenance CAM-Inspect CAM for broken and/or cracked case. Inspect outside of CAM for dirt, corrosion, distortion, and cracked, broken, and/or missing parts including nozzle protective cap assembly, display, battery cap assembly, environmental cap, and two push-button switches with rubber covers. Battery-Twist (counterclockwise) and remove battery cap assembly. Inspect that a battery is installed in receptacle.

Preventative Maintenace Continued Spare Battery- Check that spare battery is in carrying harness pocket. Inspect battery for cracks, dents, bulging, and corrosion Confidence Sample- Check that confidence sample is in carrying harness pocket. Remove confidence sample from pocket and inspect for cracks, breakage, or other damage. Check that plunger (10) goes up and down for both modes. Return confidence sample to carrying harness pocket.

Preventative Maintenance Continued Spare Nozzle Protective Cap Assembly- Inspect packing can to ensure no punctures. DO NOT OPEN PACKING CAN UNTIL SPARE NOZZLE PROTECTIVE CAP IS REQUIRED. Buzzer- Inspect for cracked, broken, or missing parts. Install battery Battery Assembly, Training- Inspect the BAT for dirt and cracked, broken, or missing parts. Remove all dirt from the BAT prior to use CAUTION- Make this inspection as quickly as possible to avoid possible contamination of the nozzle protective cap assembly.

To start self-test, press ON/OFF push-button switch (3). Pre-Operation Tests Self- Test: This procedure applies power to your system. Look for visual indications to ensure CAM is operating property. Ensure nozzle protective cap (1) is in position on monitor case assembly (2). To start self-test, press ON/OFF push-button switch (3).

Markers A and B (6) are shown. All eight bars (7) are shown. Self-Test Continued H mode (4) is shown. If G mode is shown, press G/H mode push-button switch. Turn CAM off, then on again. Verify H mode is shown. Markers A and B (6) are shown. All eight bars (7) are shown. Three vertical dots (8) are shown. BL (9) is shown. WAIT (10) is shown. Display will clear from self-test after 30 seconds (H mode, WAIT and A and B markers remain). WAIT clears from display within 2 minutes.

Confidence Test This test uses a confidence sample (simulant) to detect and display the presence of hazardous chemical nerve or mustard agents. It is performed after completing a selftest or changing modes. Twist (counterclockwise) and remove nozzle protective cap (1) from front of CAM (2); place nozzle protective cap onto CAM environmental cap (3) and twist clockwise. Place a filtered nozzle standoff onto CAM nozzle assembly, as follows: Pull one filtered nozzle package assembly (4) from pocket (5) of carrying harness.

Confidence Test Continued Peel back covering from top of filtered nozzle package assembly until one filtered nozzle standoff is exposed. Quickly press CAM nozzle assembly into exposed filtered nozzle standoff and remove. Lay covering back in place across top of filtered nozzle package assembly. Slide package assembly back into pocket of carrying harness. Remove environmental cap and nozzle protective cap combination by twisting counterclockwise. Install buzzer onto electrical connector by twisting the ring clockwise.

Confidence Test Continued Make sure CAM display indicates H mode. Perform H confidence test as follows: Remove confidence sample from carrying harness Grasp confidence sample with H end exposed Do not allow the CAM to sample the confidence sample for more than 1 second. Longer than 1 second will saturate the CAM with vapor. It is only necessary that at least three bars show for test verification (do not attempt to have all bars show) Press firmly CAM nozzle assembly in H end of confidence sample for 1 second Remove confidence sample

Confidence Test Continued Verity that at least three bars (1) are displayed after a few seconds. Three dots may appear momentarily; ignore them Display should clear to zero or one bar within 2 minutes Press G/H mode push-button switch; verify mode changes from H to G. WAIT may be displayed for several seconds. When WAIT disappears, proceed. The three dots may also appear following the mode change - Ignore them.

Confidence Test Continued Perform G confidence test the same as the H confidence test using the G end of the confidence sample Place confidence sample (1) into pocket (2) of carrying harness (3). CAM is ready for operation.

Proper Procedures When Using the ICAM Proper personnel detection using ICAM Turn ICAM on Perform self test (performed in H Mode) Perform confidence test Place ICAM in H Mode Hold ICAM 1/2 inch from the object being monitored To change from H Mode to G Mode, press G H Mode pushbutton switch; verify display indicates G Mode. WAIT may be displayed for several seconds. When WAIT has disappeared, proceed. The three dots may also appear following the mode change. Wait until the dots disappear Hold CAM 1/2 inch away and monitor object in G Mode If the operation of the CAM is in doubt at any time, the filtered nozzle standoff should be removed and the protective cap assembly replaced on the nozzle assembly. When the display has cleared down to one or zero bars, the nozzle protective cap assembly is removed and a new filtered nozzle standoff installed. A confidence test is performed and monitoring can then continue
