3 What is the HAZMATCADTM?
The HAZMATCAD™ is a next generation handheld trace chemical agent detector for Nerve (G) and Blister (H) agents as well as Hydrogen Cyanide (AC) or Phosgene (CG). The HAZMATCAD™ is designed to detect for these warfare agent gases with minimal interference from other chemicals which are often present in the battlefield or urban environment.


5 What is the HAZMATCAD™ Plus?
The HAZMATCAD™ Plus expands the performance of HAZMATCAD™ by adding the ability to detect selected TICs (Toxic Industrial Chemicals). These chemicals are detected and reported by class identification (hydride and halogen gases).

6 HAZMATCAD™ Configurations
HAZMATCAD™ Plus SAW (nerve and blister) Four electrochemical cells (blood, choke, halogen and hydride gases) HAZMATCAD™ SAW (nerve and blister) One electrochemical cell (blood or choke)

7 False Alarms vs. Analysis Time
Fast Response Time – IMS – Typically (5 to 30 sec) Direct readout of total contamination No sample pre-collection or clean up Increased risk of false positives HAZMATCAD™ Analysis Time – SAW (20 to 120 sec) Fast Mode (20 sec) or High Sensitivity Mode (120 sec) Sample collection on absorbant media Sample control Reduced risk of false positives

8 How Does a SAW Sensor Work?
Small Piezoelectric Crystal Interdigital Array Polymer Surface Coating RF Electronics to Drive SAW Data Collection - frequency changes as mass absorbs into polymer

9 SAW Sensor Fundamentals

10 Benefits of SAW Technology
Long Term Sensor Stability Semi Selective Chemical Detection Partition Coefficient Equilibrium Detection Mechanism Quick Response and Fast Recovery Better Sample Characterization

20 HAZMATCAD™ User Interface
Controls  On / Off Switch  Battery Door  External Communication / RS-232 Connection − DIN 9-Pin or IrDA (Optional Accessory) Sample Inlet Port Three Position  Open, Closed, and Dust Filter Information / Status Panel  Display LED 4-Character Alphanumeric

21 HAZMATCAD™ Analysis Cycle – Fast Mode
Analysis Cycle is 20 Seconds  Sample Collection − Pump On − 1-11 Seconds  Sample Preheat − Pump Off / Concentrator On − Seconds  Sample Injection − Seconds Repeats Cycle Sequence Until Turned Off

22 HAZMATCAD™ Analysis Cycle - High Sensitivity Mode
Analysis Cycle is 120 Seconds  Sample Collection − Pump On − Seconds  Sample Preheat − Pump Off / Concentrator On − Seconds  Sample Injection − Seconds Repeats Cycle Sequence Until Turned Off

23 HAZMATCAD™ Change Mode Cycle
Press “MODE” Button Current Mode will display on LED  “FAST” or “HI S” (High Sensitivity) While “Mode” is displayed, press “MODE” again New Mode will flash on LED A purge cycle will begin (i.e. Start Over)

24 HAZMATCAD™ Training Mode
Press the ON Button HAZMATCAD will perform a self test When /////// is displayed on the LED, press and hold the “Mode Select” button Audible alarm will beep to confirm training mode has started After warm up, HAZMATCAD will chirp every three seconds Turn off HAZMATCAD to deactivate

31 Check Source Verification
Chemical Simulant for “G” Agent Dimethyl Methlyphosphonate (DMMP) Verify Check Source Expiration Date 6 months from date on tube MSDS - Appendix A in Operation Manual A Successful Test indicates the HAZMATCADTM is fully operational for Nerve and Blister Agent Detection No need to test separately for Blister

32 How to use Simulant Check Source
Power Up HAZMATCADTM Allow HAZMATCADTM to report “ALL CLEAR” Prepare Check Source - remove vinyl end caps Position Sample Inlet to “OPEN” position Listen for Pump Operation When pump pauses, wait 10 seconds Hold Simulant Check Source to Sample Inlet for 3 seconds then remove “G” Alarm should be indicated on next analysis Allow HAZMATCADTM to return to “ALL CLEAR”

2 SONY NP-F550 Rechargeable Lithium Ion Batteries Can operate on one battery 8 to 12 hours of operation (dependent on Mode) Fast Mode = 8 hours High Sensitivity Mode = 12 hours Can remove batteries while operating (HOT SWAP) NP-F550 batteries require periodic charging Typical recharge time is approximately 1 hour Battery charger will indicate charge level

34 HAZMATCADTM Decontamination
Turn HAZMATCAD OFF Place the three position sample port in the CLOSED position Wipe down completely with moist, soapy cloth Shake HAZMATCAD briskly to remove residual liquid Place three position sample port in OPEN position and invert HAZMATCAD for two minutes Wipe dry with clean towel, paper towel or clean rag Place the HAZMATCAD in a sealed bag for one hour Sample the headspace of the bag using another HAZMATCAD, M256 kit or other appropriate device If residual contamination is detected, repeat steps 1 thru 8

35 HAZMATCADTM Check for Internal Contamination
Place an operating HAZMATCAD in a large plastic bag and seal it Let the HAZMATCAD run for 60 minutes Sample the headspace of the bag with another HAZMATCAD, M256 kit or other appropriate device for trace contamination If contamination is detected, run the HAZMATCAD in clean air for several hours and repeat steps 1 thru 3 If HAZMATCAD still shows traces of contamination, contact Microsensor Systems, Inc. or the appropriate government agency
