CHEMICAL DETECTION & IDENTIFICATION CATEGORIES
answer
-STANDOFF - POINT - MONITORING
question
Purpose of Standoff Detection
answer
- provides advanced warning - Tactical intelligence determines level of countermeasure preparation - Conserves critical manpower resources
question
Purpose of Point Detection
answer
- to identify the physical arrival of chemical agents at a designated location
question
Purpose of Monitoring
answer
- To establish the presence or absence of chemical agent in vapor form in the atmosphere or in liquid form on a surface.
question
Methods of Point Detection
answer
- Automatic (IPDS/IPDS-LR)/Manual (M-8/M-9) -Periodic monitoring (M-8/M-9)
question
Methods of Monitoring
answer
Detectors: M-8, M-9, M256-A1/A2
question
IPDS stands for and is used for :
answer
IMPROVED (CHEMICAL AGENT) POINT DETECTION SYSTEM (IPDS) IPDS is a fixed-point detection system used to detect and alarm for chemical nerve and blister agent vapor hazards. Provides real time response to low concentrations of G & V series nerve agents (0.1 mg/m3) and H series blister agents (10 mg/m3 in 60 seconds).
question
IPDS is directly wired into the:
answer
ship's chemical alarm.
question
IMS Stands for:
answer
ION MOBILITY SPECTROSCOPY
question
IMS is used to:
answer
analyze the air sample, and, if chemical agent vapors are detected, provide digital signals to activate visual and audible alarms at the CDU and RDU.
question

answer
IMS Cells used in IPDS
question
IPDS Modes of Operation
answer
- Standby Mode CMWD - Running Sample Mode - Confidence Test Mode - Manual Self-Test Mode
question
What is the utility of IPDS-LR
answer
- a fixed-point detection system used to detect and alarm for chemical nerve, blister, and blood agent vapor hazards. - real time response to low concentrations of G & V series nerve, H series blister, and AC and CK series blood agents.
question
IPDS-LR Modes of Operation
answer
- Standby Mode CMWD - Running/Sampling Mode - DU Confidence Test - Built In Test (BIT)
question
What is Ships force not permitted to work on because of Nickle-63?
answer
IMS Cells in IPDS-LR
question
M9 Chemical Detection Paper Characterisitics
answer
- Detects the presence liquid nerve & blister agents (G&V Series and H&L agents) (doesn't identify) - droplets >100microns - response time <10 sec - Chemical agent sensitive dye on paper - protective layer - adhesive coating - Carcinogenic (old)

question
M-8 Chemical detection paper detects what types of liquid agents?
answer
Blister (H & L) Nerve (G & V)
question
M9 Paper Detects what type of liquid agents?
answer
G&V Series and H&L agents)
question
Who is on the CHEMICAL DETECTION SURVEY AND MONITORING TEAM
answer
1 Team leader 2 samplers 1 Messenger/marker
question
Steps to CONTAMINATIONLOCATION AND ISOLATION in Chemical Agent Detection
answer
Location - Stations set in CBRD bill - Post M-8/M-9 paper - Re-verify with M256A1/A2 - Inside to outside Isolation - when located - rope off all accesses and mark with signs - pass word Deploy Decontamination Teams - If necessary
question
Detection Kits to use in Chemical Surveys
answer
Periodic Monitoring (Point Detection) Prior/During attack (M8/M9, IPDS, IPDS-LR) On-Station Monitoring During attack (M256A1/A2/M8/M9) Rapid Internal Survey After attack (M256A1/A2) Rapid External Survey After RIS (M8/M9) Supplemental Surveys As required/as time permits
question
M256A1 & M256A2 Response Time
answer
17-20 Mins
question
M-8 Paper Response Time
answer
20 sec
question
M-9 Paper Response Time
answer
10 sec
question
Whats the difference between M8 and M9 paper?
answer
M8 paper identifies the type of agent present, M9 Paper just determines an agent is present.
