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.

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).

What is the HAZMATCAD™ Plus?

HAZMATCAD™

SAW (nerve and blister)

One electrochemical cell (blood or choke)

HAZMATCAD™ Plus

SAW (nerve and blister)

Four electrochemical cells (blood, choke, halogen and hydride gases)

HAZMATCAD™ Configurations

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

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

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”

HAZMATCADTM Li-Ion Battery

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

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

HAZMATCADTM Check forInternal 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
