WARNINGRADIATION HAZARD

NICKEL-63 (Ni-63)

The Chemical Agent Monitor (CAM) contains a beta radiation source licensed for use bythe Nuclear Regulatory Commission (NRC). Federal law mandates control of thisradioactive material. The source is a plated cylinder of 10 millicuries of Nickel-63. If theCAM is lost or stolen, notify the NBC Officer/NCO and the local Radiation ProtectionOfficer (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 originalpacking container, if available, to Direct Support Maintenance for evaluation. If skincontact is made with any area thought to be contaminated with Nickel-63, washimmediately with nonabrasive soap and water.

5. Follow safety procedures for storage, shipment, and disposal in accordance with thismanual, local regulations, AR 710-3, and AR 385-11.

WARNING

FLAMMABLE AND CORROSIVE HAZARD

Lithium-sulfur dioxide batteries contain lithium, sulfur dioxide and anelectrolyte. Sulfur dioxide is an irritant gas. The electrolyte is flammableand highly corrosive. Do not immerse in water or decon solution, crush,or bum batteries. Do not attempt to recharge batteries or store attemperatures above 158°F (70°C). If a battery is mishandled or misusedthe lithium may rapidly vent out, carrying with it the sulfur dioxide gasand 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 thebattery, move it outside by using a shovel or long tongs. Wear suitable protection whenhandling suspect batteries. A rapidly venting battery may create an explosive andcorrosive hazard which may damage skin and eyes. If the skin or eyes come in contactwith the electrolyte wash thoroughly with generous amounts of water, and seek medicalattention. Dispose of batteries according to TB 43-0130 and local Standing OperatingProcedures (SOP).

CAUTION

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

Section III. PRINCIPLES OF OPERATION

1-12. PRINCIPLES OF OPERATION.

The CAM has two operating modes, selectable by means of the G/H mode push-button switch: in the G mode, the CAM monitors for nerve agents; in the H mode, theCAM monitors for mustard agents. The selected mode is indicated on the displayassembly by G or H. An ON/OFF push-button switch applies 6 V dc battery power to theCAM. 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 usedto monitor for contamination.

The CAM samples air in the immediate vicinity of the nozzle for the presence of Gor H chemical agents. Air sample conditions a short distance away from the CAM may bequite different, and a change in wind direction could quickly bring a hazardous level ofagent vapor to a previously safe area.

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 onemode to the other are given (para 2-6b).

(2) General use - general use of the CAM is discussed (para 2-6c). YourTraining Circular 3-4-1 will provide details on using the CAM during amission.

(3) Interferents - a few harmless vapors in the atmosphere can give falseresponses in CAM (para 2-6d).

(4) Malfunction recognition - certain readings on the CAM display indicate amalfunction (para 2-6e) during operation.

(5) Removing CAM from operation - procedures for decontaminating andcleaning 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 nozzlestandoff.

To change modes, proceed as follows:

(1) Observe the display (1) to see which mode is shown. Press G/H modepush-button switch (2); verify that display (1) indicates the other mode.WAIT will be displayed for several seconds. When WAIT hasdisappeared, proceed. The three dots may also appear following themode change - ignore them. If display flashes on and off, go totroubleshooting 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


c. General Use.

CAUTION

Do not contaminate the filtered nozzle standoff by allowing it to come in contactwith liquid agent.

During operation in very dusty conditions, frequently inspect the filtered nozzlestandoff for collection of dust. If dust is visible, remove and replace with a newfiltered nozzle standoff. If possible, perform this action away from the dustyconditions.

Avoid excessive exposure to simulant/agent. As soon as CAM responds tosimulant/agent, back away from simulant/agent. Saturating CAM withsimulant/agent will add to clear-down time and cause maintenance down-time.

Handle CAM carefully. It is a sensitive instrument and can be damaged bydropping it or by bumping the nozzle.

2-36

NOTE

Get to know your operating environment (know local interferents). Do not obstruct thefiltered nozzle standoff.

(1) If the operation of the CAM is in doubt at any time, the filtered nozzlestandoff should be removed and the nozzle protective cap assemblyreplaced on the nozzle assembly. When the display has cleared down tozero or one bar, the nozzle protective cap assembly is removed and a newfiltered nozzle standoff installed. A confidence test is performed, andmonitoring can then continue.

(2) When a constant number of bars are continually shown on the display, itusually Indicates that contamination is present in the surrounding area oron the nozzle. Discard filtered nozzle standoff as contaminated waste. Donot allow CAM to continuously monitor contamination of any kind.

(3) Because the CAM is a point monitor and can report conditions only at thefront of the nozzle assembly, it is necessary to move the CAM around thearea when carrying out a complete reconnaissance.

2-37


c. General Use. (Cont).

NOTE

If there is a source of vibration in the area, WAIT may be displayedmomentarily. Searching for agent should cease until WAITdisappears.

(4) When monitoring for contamination on a person, object, vehicle, aircraft orpiece of equipment, it is essential to first establish what general vaporhazard (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 isdisplayed.

(5) Switch CAM off when not in use to extend battery life.

(6) In cold weather, liquid contaminants may not release sufficient vapor toproduce a reading on CAM.

2-38

d. Interferents.

NOTE

Monitoring with CAM is usually done outdoors while in Mission OrientedProtective Posture (MOPP IV). Cleaning materials or perfumes may bea problem.

(1) There are a few vapors present in the atmosphere that can, in somecircumstances, give a false response in CAM. The situations most likely togive a false response are in enclosed spaces or when sampling nearstrong vapor sources, for example, in a motor pool engine test bay. If it ispossible, get to know your local environment during training periods.Determine if, for example, there are any responses in the galley, the sickbay or the hangar. Some of the types of vapors that have been found togive false readings are given in the following paragraphs:

2-39


d. Interferents (Cont).

(a) Cleaning compounds. Some cleaning compounds and disinfectantscontain additives which give them a pleasing smell. Some of theseadditives such as menthol and methyl salicylate (MS) can give falseresponses in the H or G mode. Cleaning materials are by their verynature spread over large surface areas and, therefore, provide aconsiderable vapor source, particularly in enclosed spaces.

(b) Aromatic vapors. Included in this group of materials are perfumes andfood flavorings. Some brands of aftershave and perfume can give aresponse 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 Gmode if the breath is exhaled directly into the CAM nozzle.

2-40

(c) Smoke and fumes. The exhaust from some rocket motors and thefumes 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 knowninterferents.

(c) Remove and discard the filtered nozzle standoff, place nozzleprotective cap assembly onto the front of CAM case and reestablish aclean air background.

(d) Remove nozzle protective cap assembly. If false response recurs,CAM may not be operable in the immediate area. Remove source ofinterferent (if possible) or replace nozzle protective cap and removeCAM from area.

2-41


e. Malfunction Recognition.

If one or more of the following symptoms occur during operation, refer to thetroubleshooting symptom index in para 3-3.

(1) Backlight not operating.

(2) BL shown on display duringoperation.

(3) Display disappears.

(4) Display flashes on and off.

(5) Does not change mode from Gto H or H to G.

(6) Does not clear down to zero orone bar in 2 minutes (or 5minutes 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 decontaminationprocedures. 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 carryout the shutdown procedure. When operating in wet conditions, try to avoidtrapping moisture on nozzle assembly or inside the nozzle protective capassembly. Trapping of water in this way may result in increased start-up time orreduced sensitivity.

2-43


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 arenoticed, attempt to shake off moisture.

(4) Twist (counterclockwise) and remove nozzle protective cap (3) fromenvironmental 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 actionstops the purging of any contaminant remaining, this would extend the warm-uptime on future use.

2-44

NOTE

CAM normally clears down to zero or one bar within 2 minutes. If CAM iscontaminated, 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/Hpushbutton switch to change modes of operation. Observe display (7). Ifdisplay shows zero or one bar, CAM is ready for shutdown procedure. Ifmore 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 tozero or one bar.

WARNING

FLAMMABLE AND CORROSIVE HAZARD

Lithium-sulfur dioxide batteries contain lithium, sulfur dioxide and anelectrolyte. Sulfur dioxide is an irritant gas. The electrolyte is flammable andhighly corrosive. Do not immerse in water or decon solution, crush, or bumbatteries. Do not attempt to recharge batteries or store at temperatures above158°F (70°C). If a battery is mishandled or misused the lithium may rapidly ventout carrying with it the sulfur dioxide gas and the electrolyte, and it may heatup. If this happens, stay away until the smell of sulfur is gone. If you have tomove the battery, move it outside by using a shovel or long tongs. Wearsuitable protection when handling suspect batteries. A rapidly venting batterymay damage skin and eyes. If the skin or eyes come in contact with theelectrolyte, wash thoroughly with generous amounts of water, and seekmedical attention.
