M8 Detector Paper

O In plastic bag inside chemical agent detector kits (M256/M256A1) O There are 25 sheets per booklet O Detects agents

liquid

nerve

and

blister

Color Changes O Yellow-gold indicates G (nerve) agent O Red-pink indicates H (blister) agent O Dark green indicates V (nerve) agent O If any other color or no color change, liquid cannot be identified

4

False Negatives

WARNING—When conducting agent tests at night, remove any colored lens because it may provide a false negative response.

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.

Learning Objective B

This objective will address how to detect chemical agents using M9 detector paper.

031-503-1037 VG 11

M9 Detector Paper O In a dispenser roll O Detects chemical agents O Cannot be used to identify chemical agents O Used in all types of weather/temperatures O Sticks to clothing, vehicles, other equipment 031-503-1037 VG 12

Procedures to Use M9 Paper O Attach M9 detector paper to protective clothing O Wrap M9 paper around upper arm O Wrap M9 paper around wrist of jacket O 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.

Procedures to Use M9 Paper O Attach M9 paper to surfaces most likely to encounter chemical agents O Note any color changes on M9 paper O Constantly monitor M9 paper for any color change O If color changes: mask, give the alarm, decon (as necessary), assume MOPP4 031-503-1037 VG 15
