The Hazmatcad is a chemical agent detector for first responders.
Always deploy the Hazmatcad device in a safe zone.
Insert two Sony lithium-ion batteries (model NP-550) into the battery compartment and close the door.
Slide the three-position sample port cover on top of the device to the DUST FILTER position. This prevents particulates from entering the unit during startup.
Press the ON button on the front of the device.
The unit will cycle through a series of diagnostics.
When the self-test has completed successfully, the LED beside SYS OK will begin to flash green. This indicates that the device is functioning properly.
In the event of a fault detection, information will appear on the display.
Next, the current operation mode will flash on the display. FAST indicates Fast Mode (default) and HI S indicates Hi S Mode.
After this, the device will perform a system purge to remove accumulated contaminants. The message WARM UP will flash on the display (illustrated to the left).
When the display goes blank, the device is operational. The LED beside SYS OK will flash again and the first sample analysis will begin. The LED beside ALL CLEAR will be solid green if the area is free of contamination.
Note that if a hazardous agent is present where the device has been deployed, the LED beside ALARM will flash red instead. The type and level of the chemical agent will appear on the display.
Which setting should you move the three-position sample port cover to before starting the Hazmatcad?
- Dust Filter
Vapor Stimulant Check
Before leaving the safe zone, test the device to ensure that it is properly detecting nerve and blister agents.
- Slide the three-position sample port cover to OPEN.
- Remove the caps from the stimulant check source and hold the tube against the sample inlet port for 3 to 4 seconds.
- If successful, the device will read G on the display and the LED beside ALARM will glow red. This indicates that nerve and blister agents were detected. Levels include LOW, MED, and HIGH and chemical agent codes are G, H, TOX, BLoD, CHOK, HYdr, and HALO.
- Run the device until the LED beside ALL CLEAR glows green steadily.
- Slide the three-position sample port cover back to DUST FILTER.
Note: To check halogen cell response, instead hold a cotton swab dipped in chlorine bleach close to the sample inlet port. Repeat steps 4 and 5 after the agent has been detected.
Ready For Use
As you proceed into the potentially hazardous area, the device will respond with either a continuous ALL CLEAR response or with an alarm.
The alarm is indicated by a red LED and the associated type and level of the chemical agent.
The levels are indicated as LOW, MED, or HIGH and the chemical agent codes are G, H, TOX, BLoD, CHOK, HYdr, and HALO.
