Terminal Learning Objective • Upon completion of this lesson, you will understand the procedures to detect chemical agents using M8 or M9 detector paper. 031-503-1037 VG 1
Learning Objective A • This topic will address how to use M8 detector paper to identify chemical agents. 031-503-1037 VG 2
M8 Detector Paper • In plastic bag inside chemical agent detector kits (M256/M256A1) • There are 25 sheets per booklet • Detects liquid nerve and blister agents 031-503-1037 VG 3
Color Changes • Yellow-gold indicates G (nerve) agent • Red-pink indicates H (blister) agent • Dark green indicates V (nerve) agent • If any other color or no color change, liquid cannot be identified 031-503-1037 VG 4
False Negatives • WARNING—When conducting agent tests at night, remove any colored lens because it may provide a false negative response. 031-503-1037 VG 5
False Positives • WARNING—Some decontaminants give false positive readings. The M8 paper may indicate positive results if used in an area where decontaminants have been used. 031-503-1037 VG 6
When to Use M8 Paper • See a liquid that might be a chemical agent • Observe any color change on M9 detector paper • Notice chemical agent symptoms in soldiers 031-503-1037 VG 7
Procedures to Use M8 Paper • Immediately assume MOPP4 • Locate liquid contamination • Remove the M8 detector paper from mask carrier • Prepare M8 detector paper 031-503-1037 VG 8
Procedures to Use M8 Paper • Blot (DO NOT RUB) M8 paper on suspected liquid agent • Observe paper for a color change • Compare color on paper to color chart in booklet 031-503-1037 VG 9
Procedures to Use M8 Paper • Close/store booklet of M8 detector paper • Remain in MOPP4 • Use other chemical agent detectors to verify test results • Report test results to supervisor 031-503-1037 VG 10
Learning Objective B • This objective will address how to detect chemical agents using M9 detector paper. 031-503-1037 VG 11
M9 Detector Paper • In a dispenser roll • Detects chemical agents • Cannot be used to identify chemical agents • Used in all types of weather/temperatures • Sticks to clothing, vehicles, other equipment 031-503-1037 VG 12
Procedures to Use M9 Paper • Attach M9 detector paper to protective clothing • Wrap M9 paper around upper arm • Wrap M9 paper around wrist of jacket • Wrap M9 paper around ankle just above boot 031-503-1037 VG 13
Overlap of M9 Paper • CAUTION: Leave at least one inch of overlap when placing paper on MOPP gear to minimize the difficulties experienced while conducting MOPP gear exchange. 031-503-1037 VG 14
Procedures to Use M9 Paper • Attach M9 paper to surfaces most likely to encounter chemical agents • Note any color changes on M9 paper • Constantly monitor M9 paper for any color change • If color changes: mask, give the alarm, decon (as necessary), assume MOPP4 031-503-1037 VG 15
