VG Terminal Learning Objective Upon completion of this lesson, you will understand the procedures to detect chemical agents using M8 or M9 detector paper.

VG Learning Objective A This topic will address how to use M8 detector paper to identify chemical agents.

VG M8 Detector Paper OIn plastic bag inside chemical agent detector kits (M256/M256A1) OThere are 25 sheets per booklet ODetects liquid nerve and blister agents

VG Color Changes OYellow-gold indicates G (nerve) agent ORed-pink indicates H (blister) agent ODark green indicates V (nerve) agent OIf any other color or no color change, liquid cannot be identified

VG False Negatives WARNINGWhen conducting agent tests at night, remove any colored lens because it may provide a false negative response.

VG False Positives WARNINGSome decontaminants give false positive readings. The M8 paper may indicate positive results if used in an area where decontaminants have been used.

VG When to Use M8 Paper OSee a liquid that might be a chemical agent OObserve any color change on M9 detector paper ONotice chemical agent symptoms in soldiers

VG Procedures to Use M8 Paper OImmediately assume MOPP4 OLocate liquid contamination ORemove the M8 detector paper from mask carrier OPrepare M8 detector paper

VG Procedures to Use M8 Paper OBlot (DO NOT RUB) M8 paper on suspected liquid agent OObserve paper for a color change OCompare color on paper to color chart in booklet

VG Procedures to Use M8 Paper OClose/store booklet of M8 detector paper ORemain in MOPP4 OUse other chemical agent detectors to verify test results OReport test results to supervisor

VG Learning Objective B This objective will address how to detect chemical agents using M9 detector paper.

VG M9 Detector Paper OIn a dispenser roll ODetects chemical agents OCannot be used to identify chemical agents OUsed in all types of weather/temperatures OSticks to clothing, vehicles, other equipment

VG Procedures to Use M9 Paper OAttach M9 detector paper to protective clothing OWrap M9 paper around upper arm OWrap M9 paper around wrist of jacket OWrap M9 paper around ankle just above boot

VG 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.

VG Procedures to Use M9 Paper OAttach M9 paper to surfaces most likely to encounter chemical agents ONote any color changes on M9 paper OConstantly monitor M9 paper for any color change OIf color changes: mask, give the alarm, decon (as necessary), assume MOPP4
