WARNING RADIATION HAZARD

NICKEL-63 (Ni-63) The Chemical Agent Monitor (CAM) contains a beta radiation source licensed for use by the Nuclear Regulatory Commission (NRC). Federal law mandates control of this radioactive material. The source is a plated cylinder of 10 millicuries of Nickel-63. If the CAM is lost or stolen, notify the NBC Officer/NCO and the local Radiation Protection Officer (RPO) immediately.

SAFETY PRECAUTIONS 1.

Handle the CAM carefully.

2.

DO NOT attempt to OPEN the CAM case.

3.

If the CAM case is broken or cracked, inform the NBC Officer/NCO, and if available, the local Radiation Protection Officer (RPO).

SAFETY PRECAUTIONS (CONT) 4. A broken or cracked CAM should be wrapped in a plastic bag and shipped in original packing container, if available, to Direct Support Maintenance for evaluation. If skin contact is made with any area thought to be contaminated with Nickel-63, wash immediately with nonabrasive soap and water. 5. Follow safety procedures for storage, shipment, and disposal in accordance with this manual, local regulations, AR 710-3, and AR 385-11.

WARNING FLAMMABLE AND CORROSIVE HAZARD Lithium-sulfur dioxide batteries contain lithium, sulfur dioxide and an electrolyte. Sulfur dioxide is an irritant gas. The electrolyte is flammable and highly corrosive. Do not immerse in water or decon solution, crush, or bum batteries. Do not attempt to recharge batteries or store at temperatures above 158°F (70°C). If a battery is mishandled or misused the lithium may rapidly vent out, carrying with it the sulfur dioxide gas and the electrolyte, and it may heat up.

b

If this happens, stay away until the smell of sulfur is gone. If you have to move the battery, move it outside by using a shovel or long tongs. Wear suitable protection when handling suspect batteries. A rapidly venting battery may create an explosive and corrosive hazard which may damage skin and eyes. If the skin or eyes come in contact with the electrolyte wash thoroughly with generous amounts of water, and seek medical attention. Dispose of batteries according to TB 43-0130 and local Standing Operating Procedures (SOP).

CAUTION Do not decontaminate CAM or Its accessories with M258A1 or M280 Decontamination Kits. These kits may cause false positives and temporarily render the CAM inoperative.

FIRST AID For first aid information, refer to FM 21-11.

1-11. SAFETY, CARE, AND HANDLING (CONT). a. Rules and Regulations (CONT). The license requires the cell, a component of the CAM, be wiped tested annually and tracked throughout its life cycle in accordance with AR 710-3. b. Posting Requirements. Federal law requires certain notices, instructions, and standards be made available to all users of items which contain licensed radioactive material. Contact Unit Maintenance or Direct Support for instructions about Title 10 Code of Federal Regulation, NRC Form 3 (Notice to Employees) and Public Law 93-438. c. Repair/Disposition. A malfunctioning CAM should be given to your NBC NCO for return to Direct Support Maintenance.

1-12

d. Emergency Procedures. WARNING In an emergency, contamination must be considered present until determined otherwise or contamination of personnel may result. (1) Fire. The basic concern is possible airborne contamination carried out of the flames by the heated air and in the smoke. Firefighters should fight the fire from upwind, and wear portable air systems, if available. After the fire Is extinguished, debris must be surveyed for the presence of equipment containing Nickel-63 sources. The RADIAC set ANNDR-2 (or equivalent) (with the beta shield open) is suitable for detecting the location of the Nlckel-63 sources. Wipes must be taken and evaluated to determine contamination. (2) Equipment Destruction. Parts of the equipment must be retrieved, and surveys for possible contamination must be done. (3) Accident Response in General. (a) Remove injured and spectators. (b) Establish exclusion area. (c) Notify authorities (NBC NCO or officer, and, if available, local RPO). 1-13

Section III. PRINCIPLES OF OPERATION 1-12. PRINCIPLES OF OPERATION. The CAM has two operating modes, selectable by means of the G/H mode pushbutton switch: in the G mode, the CAM monitors for nerve agents; in the H mode, the CAM monitors for mustard agents. The selected mode is indicated on the display assembly by G or H. An ON/OFF push-button switch applies 6 V dc battery power to the CAM. A nozzle protective cap assembly contains material to clean the air within the CAM; the cap assembly is located in the front of the CAM whenever the CAM is not being used to monitor for contamination. The CAM samples air in the immediate vicinity of the nozzle for the presence of G or H chemical agents. Air sample conditions a short distance away from the CAM may be quite different, and a change in wind direction could quickly bring a hazardous level of agent vapor to a previously safe area.

2-28

CAUTION 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). (3) Press firmly CAM nozzle assembly (1) in H end of confidence sample (2) for 1 second (confidence sample should touch filtered nozzle standoff). (4) Remove confidence sample (2).

2-29

2-5. CONFIDENCE TEST (CONT). (5) Verity that at least three bars (1) are displayed after a few seconds. Three dots may appear momentarily; ignore them. If fewer than three bars appear, refer to troubleshooting symptom 8 (para 3-3). If three or more bars appear, but the buzzer does not sound, refer to troubleshooting symptom 9 (para 3-3). (6) Display should clear to zero or one bar within 2 minutes; if CAM does not clear to zero or one bar within 2 minutes, refer to troubleshooting symptom 6 (para 3-3). (If display shows five or more bars (1) CAM may need approximately 5 minutes to clear.)

2-30

e. Press G/H mode push-button switch (1); verify mode changes from H to G (2). WAIT may be displayed for several seconds. When WAIT disappears, proceed. The three dots may also appear following the mode change - Ignore them. If display flashes on and off, go to troubleshooting symptom 4 (para 3-3).

2-31

2-5. CONFIDENCE TEST (CONT). f. Perform G confidence test the same as the H confidence test using the G end of the confidence sample. g. Place confidence sample (1) into pocket (2) of carrying harness (3). CAM is ready for operation.

2-32

2-6. OPERATING PROCEDURES. a. The CAM operating procedures consist of: (1) Changing mode (G to H or H to G) - procedures for changing from one mode to the other are given (para 2-6b). (2) General use - general use of the CAM is discussed (para 2-6c). Your Training Circular 3-4-1 will provide details on using the CAM during a mission. (3) Interferents - a few harmless vapors in the atmosphere can give false responses in CAM (para 2-6d). (4) Malfunction recognition - certain readings on the CAM display indicate a malfunction (para 2-6e) during operation. (5) Removing CAM from operation - procedures for decontaminating and cleaning the CAM are given (para 2-6f). (6) Shutdown - shutdown procedures are listed (para 2-6g). 2-33

2-6. OPERATING PROCEDURES (CONT). b. Changing Modes: G to H or H to G. NOTE If agent has been identified prior to switching modes, replace filtered nozzle standoff. To change modes, proceed as follows: (1) Observe the display (1) to see which mode is shown. Press G/H mode push-button switch (2); verify that display (1) indicates the other mode. WAIT will be displayed for several seconds. When WAIT has disappeared, proceed. The three dots may also appear following the mode change - ignore them. If display flashes on and off, go to troubleshooting symptom 4 (para 3-3). (2) Perform a confidence test (para 2-5d or 2-5f [1 thru 6 only]). (3) Place confidence sample (3) into pocket (4) of carrying harness (5).

2-34

2-35

2-6. OPERATING PROCEDURES (CONT). c. General Use. CAUTION Do not contaminate the filtered nozzle standoff by allowing it to come in contact with liquid agent. During operation in very dusty conditions, frequently inspect the filtered nozzle standoff for collection of dust. If dust is visible, remove and replace with a new filtered nozzle standoff. If possible, perform this action away from the dusty conditions. Avoid excessive exposure to simulant/agent. As soon as CAM responds to simulant/agent, back away from simulant/agent. Saturating CAM with simulant/agent will add to clear-down time and cause maintenance down-time. Handle CAM carefully. It is a sensitive instrument and can be damaged by dropping it or by bumping the nozzle.

2-36

NOTE Get to know your operating environment (know local interferents). Do not obstruct the filtered nozzle standoff. (1) If the operation of the CAM is in doubt at any time, the filtered nozzle standoff should be removed and the nozzle protective cap assembly replaced on the nozzle assembly. When the display has cleared down to zero or one bar, the nozzle protective cap assembly is removed and a new filtered nozzle standoff installed. A confidence test is performed, and monitoring can then continue. (2) When a constant number of bars are continually shown on the display, it usually Indicates that contamination is present in the surrounding area or on the nozzle. Discard filtered nozzle standoff as contaminated waste. Do not allow CAM to continuously monitor contamination of any kind. (3) Because the CAM is a point monitor and can report conditions only at the front of the nozzle assembly, it is necessary to move the CAM around the area when carrying out a complete reconnaissance. 2-37

2-6. OPERATING PROCEDURES (CONT). c. General Use. (Cont). NOTE If there is a source of vibration in the area, WAIT may be displayed momentarily. Searching for agent should cease until WAIT disappears. (4) When monitoring for contamination on a person, object, vehicle, aircraft or piece of equipment, it is essential to first establish what general vapor hazard (G or H) is suspected. Be aware of the wind speed and direction. CAUTION Do not switch CAM off for end of mission or storage if more than one bar is displayed. (5) Switch CAM off when not in use to extend battery life. (6) In cold weather, liquid contaminants may not release sufficient vapor to produce a reading on CAM.

2-38

d. Interferents. NOTE Monitoring with CAM is usually done outdoors while in Mission Oriented Protective Posture (MOPP IV). Cleaning materials or perfumes may be a problem. (1) There are a few vapors present in the atmosphere that can, in some circumstances, give a false response in CAM. The situations most likely to give a false response are in enclosed spaces or when sampling near strong vapor sources, for example, in a motor pool engine test bay. If it is possible, get to know your local environment during training periods. Determine if, for example, there are any responses in the galley, the sick bay or the hangar. Some of the types of vapors that have been found to give false readings are given in the following paragraphs:

2-39

2-6. OPERATING PROCEDURES (CONT). d. Interferents (Cont). (a) Cleaning compounds. Some cleaning compounds and disinfectants contain additives which give them a pleasing smell. Some of these additives such as menthol and methyl salicylate (MS) can give false responses in the H or G mode. Cleaning materials are by their very nature spread over large surface areas and, therefore, provide a considerable vapor source, particularly in enclosed spaces. (b) Aromatic vapors. Included in this group of materials are perfumes and food flavorings. Some brands of aftershave and perfume can give a response in G mode when CAM is held close to the skin, for example, in casualty handling procedures. Some sweets, such as peppermints, cough lozenges and menthol cigarettes can cause a response in G mode if the breath is exhaled directly into the CAM nozzle.

2-40

(c) Smoke and fumes. The exhaust from some rocket motors and the fumes from some munitions can give responses. (2) If you suspect your CAM is giving a false reading: (a) Stay masked. (b) Check for obvious vapor sources - smoke, etc., and known interferents. (c) Remove and discard the filtered nozzle standoff, place nozzle protective cap assembly onto the front of CAM case and reestablish a clean air background. (d) Remove nozzle protective cap assembly. If false response recurs, CAM may not be operable in the immediate area. Remove source of interferent (if possible) or replace nozzle protective cap and remove CAM from area.

2-41

2-6. OPERATING PROCEDURES (CONT). e. Malfunction Recognition. If one or more of the following symptoms occur during operation, refer to the troubleshooting symptom index in para 3-3.

(1) Backlight not operating. (2) BL shown on display during operation. (3) Display disappears.

(4) Display flashes on and off.

(5) Does not change mode from G to H or H to G. (6) Does not clear down to zero or one bar in 2 minutes (or 5 minutes for five or more bars). 2-42

f.

Removing CAM from Operation. WARNING A contaminated CAM can cause death or injury to personnel. (1) If contamination is suspected, refer to para 2-17 for decontamination procedures. If CAM is not contaminated proceed to step 2. NOTE In conditions below 40°F (4°C) take CAM to a warm area, if possible, to carry out the shutdown procedure. When operating in wet conditions, try to avoid trapping moisture on nozzle assembly or inside the nozzle protective cap assembly. Trapping of water in this way may result in increased start-up time or reduced sensitivity.

2-43

2-6. OPERATING PROCEDURES (CONT). f.

Removing CAM from Operation (Cont). (2) Remove and discard filtered nozzle standoff (1) from nozzle assembly (2). (3) Inspect nozzle assembly for indications of moisture. If droplets of water are noticed, attempt to shake off moisture. (4) Twist (counterclockwise) and remove nozzle protective cap (3) from environmental cap (4). (5) Twist and install nozzle protective cap (3) onto CAM (5). (6) Remove buzzer (6) from electrical connector and install environmental cap (4) on electrical connector. CAUTION

Do not switch CAM off when one or more bars are showing because this action stops the purging of any contaminant remaining, this would extend the warm-up time on future use.

2-44

NOTE CAM normally clears down to zero or one bar within 2 minutes. If CAM is contaminated, it may take at least 1 hour to clear down to zero or one bar. (7) Observe display (7). If display shows zero or one bar, press G/H pushbutton switch to change modes of operation. Observe display (7). If display shows zero or one bar, CAM is ready for shutdown procedure. If more than one bar shows, let CAM run until display shows zero or one bar. Allow CAM to run an additional 5 minutes after the display has cleared to zero or one bar.

2-45

2-6. OPERATING PROCEDURES (CONT). f.

Removing CAM from Operation (Cont). (8) If CAM fails to clear down, in either mode, within 1 hour, refer to troubleshooting symptom 7 (para 3-3). (9) Perform shutdown procedure (para 2-6g).

g. Shutdown. Make sure you have completed “removing CAM from operation" (para 2-6f). When the display (1) shows zero or one bar (in both modes), press ON/OFF push-button switch (2) to shut CAM off. Remove battery before storing CAM in the case.

2-46

2-7. PREPARATION FOR MOVEMENT OF CAM. Do the following to prepare the CAM for movement to a new location and to return the CAM to operation at the new location. a. Remove the CAM from operation (para 2-6f). Shut down the CAM (para 2-6g). b. If carrying case is available, proceed as follows: (1) Inspect the two filtered nozzle package assemblies in the carrying harness. If either package Is empty, replace the package(s) with a new one from the lid of the carrying case assembly (para 3-5d). (2) Inspect nozzle protective cap assembly; If cap is physically damaged, replace it with the spare nozzle protective cap assembly stored in the carrying case assembly (para 3-5b).

2-47

2-7. PREPARATION FOR MOVEMENT OF CAM (CONT). b. If carrying case is available, proceed as follows (Cont): (3) Place CAM (1) into carrying case assembly (2). (4) Place buzzer (6) into carrying case assembly (2). (5) Close lid (3) on carrying case (2). Slide hand along hook-and-loop fastener (4) to secure carrying case. (6) Snap buckle halves (5) together.

Section IV. OPERATION UNDER UNUSUAL CONDITIONS 2-9. INTRODUCTION. Operation under unusual conditions includes operations in temperatures below 40°F (4°C); in temperatures above 100°F (38°C); in darkness (night operations); in blowing sand or dust; and operation where common sense dictates not operating. WARNING Individual cells within the battery contain lithium, sulfur dioxide, and an electrolyte. Sulfur dioxide is an irritant gas and the electrolyte is flammable and highly corrosive. A mishandled battery may explode or vent, release dangerous fumes, and bum. Do not crush or burn battery. Do not attempt to recharge batteries. In the event that a battery is shorted or starts to heat up, it should be removed from the CAM and taken to the outdoors or to a well-ventilated area to cool down. Tongs or a shovel are recommended for this purpose. Once the temperature has dropped or the odor of sulfur dioxide reaches a tolerable level, the battery can be disposed of according to TB 43-0130 and local SOP. Suitable protective clothing should be worn when handling suspected batteries. If the skin comes in contact with the electrolyte, wash thoroughly with water.

2-52

2-10.

OPERATION IN TEMPERATURES BELOW 40°°F (4°°C).

CAM may require a longer warm-up period in temperatures below 40°F (4°C). Before operating the CAM in temperatures below -10°F (-23°C), try to warm the battery and confidence sample by some method such as putting them in a warm facility or vehicle. They can also be placed in your pocket. A battery and/or confidence sample that is not “cold” to the touch may be considered acceptable. Never attempt to heat the battery or the confidence sample with a flame.

2-11.

OPERATION IN TEMPERATURES ABOVE 100°°F (38°°C).

In temperatures above 100°F (38°C), keep the CAM out of direct sunlight whenever possible; try to keep the CAM shaded. Don’t store the CAM in the sun. Minimize moving the CAM to and from areas of large temperature differentials (as from a cool enclosure to direct sunlight).

Change 1

2-53

2-12. OPERATION IN DARKNESS. The display contains light emitting diodes (LED) that light the display in darkness. The diodes are activated anytime that the CAM is operating.

2-13. OPERATION IN BLOWING SAND OR DUST. During operation in blowing sand or dust, check the filtered nozzle standoff for collection of dust; if dust is visible, remove and replace the filter with a new filtered nozzle standoff (para 3-5e).

2-14. COMMON SENSE OPERATION. Unless absolutely necessary, the CAM should not be used in conditions where common sense advises you not to use it. For example, don't use the CAM: a. In blowing rain or snow. b. Downwind from, or in, dense smoke or fumes. c. In enclosed spaces where there are vapor sources known to give false responses.

2-54

2-15. OPERATION WHEN FORDING AND SWIMMING. If you have to cross a river or submerse the CAM, follow the procedures for removing CAM from operation (para 2-6f) and for shutdown (para 2-6g).

2-16. EMERGENCY PROCEDURES. During an emergency, a partially malfunctioning CAM may be operated under the conditions listed below. Replace the CAM with a good unit as soon as possible. a. If CAM checks out with the confidence sample in one mode (G or H) but not In the other mode, then use the CAM In the good mode until a replacement CAM can be obtained. NOTE A constant two or three bar reading may indicate the CAM is contaminated. b. When a constant number of bars are continually shown on the display, it usually indicates that contamination is present in the surrounding area or on the nozzle. Do not allow the CAM to continuously monitor contamination of any kind. Check troubleshooting symptom 6 (para 3-3). 2-55

2-16. EMERGENCY PROCEDURES (CONT). CAUTION If dust is present, operation of the CAM without a filtered nozzle standoff can damage the CAM. Frequent confidence tests should be performed during this type of emergency operation. c. If all filtered nozzle standoffs have been used, the CAM may be operated without one. In this case, take extra precautions to prevent the nozzle assembly from touching a surface that may have liquid chemical agent on it. d. If one of the bars or the A or the B marker does not display, the CAM can be used until a replacement is available. e. If there is a crack in part of the CAM, it can still be operated if the CAM passes the self-test (para 2-4) during start up and confidence test (para 2-5). f. If the CAM display backlight (light emitting diode) is not lighting the display, the display can be observed at night by using a flashlight with a filter lens. The CAM can be used in the daylight even if the backlight is not working.

2-56

2-17. NUCLEAR, BIOLOGICAL AND CHEMICAL (NBC) DECONTAMINATION. a. Nuclear. For radiological contamination, brush, wipe or vacuum contamination from equipment. The contamination is not destroyed - just moved from one place to another - so control the runoff as contaminated waste. b. Biological and Chemical. If CAM or its accessories appear to be contaminated, the procedure described in the following paragraphs must be carried out. CAUTION Do not decontaminate CAM or its accessories with M258A1 or M280 Decontamination Kits. These kits may cause false positives and temporarily render the CAM inoperative.

3-5. OPERATOR MAINTENANCE (CONT). a. Replace Battery (Cont). WARNING FLAMMABLE AND CORROSIVE HAZARD Lithium-sulfur dioxide batteries contain lithium, sulfur dioxide and an electrolyte. Sulfur dioxide is an irritant gas. The electrolyte is flammable and highly corrosive. Do not immerse in water or decon solution, crush, or bum batteries. Do not attempt to recharge batteries or store at temperatures above 158°F (70°C). If a battery is mishandled or misused the lithium may rapidly vent out carrying with it the sulfur dioxide gas and the electrolyte, and it may heat up. If this happens, stay away until the smell of sulfur is gone. If you have to move the battery, move it outside by using a shovel or long tongs. Wear suitable protection when handling suspect batteries. A rapidly venting battery may damage skin and eyes. If the skin or eyes come in contact with the electrolyte, wash thoroughly with generous amounts of water, and seek medical attention. Dispose of batteries according to TB 43-0130 and local SOP.

E-5. OPERATOR MAINTENANCE. There is no operator maintenance for the BAT beyond the inspections identified in the operator PMCS. No repair parts are available for the nonstandard power source. NOTE If the BAT becomes contaminated during use, the operator should not attempt to decontaminate it. The BAT should be removed from the CAM and handled as contaminated waste. After replacing the battery cap assembly, the CAM may be decontaminated.

E-6. OPERATOR TROUBLESHOOTING. NOTE If any symptoms listed in para 3-3 are present, conduct troubleshooting procedures with the standard CAM battery (BA 5800/U) installed. After the CAM operates correctly with the standard CAM battery, insert the BAT. E-7

E-6. OPERATOR TROUBLESHOOTING (CONT). NOTE (CONT) If the CAM operates correctly with the standard CAM battery but malfunctions when the BAT is installed, check to make sure batteries BA 3030/U are not depleted and are installed correctly. If the CAM still does not operate correctly, dispose of the BAT and replace with standard CAM battery or another BAT. CAUTION If the CAM shows an intermittent battery low (BL) indicator, replace batteries immediately. Do not attempt to continue to operate the CAM, even if the indicator turns off temporarily. CAM may not give accurate readings.

E-7. OPERATION UNDER UNUSUAL CONDITIONS. Operations In temperatures below 50°F (10.0°C). Below 50°F (10.0°C), the alkaline D cell batteries (BA 3030/U) have a short service life. The standard CAM battery (BA 5800/U) should be used below 50°F (10.0°C). E-8
