Task: Detect chemical agents using M8 or M9 detector paper.
Conditions: You are in mission oriented posture 2 (MOPP2) in a tactical environment or an area where there is a chemical threat. You are given a protective mask, a booklet of M8 detector paper, a dispenser of M9 detector paper, an M256A1 chemical-agent detector kit.
Standards: Detect chemical agents using M8 and M9 detector paper. Ensure the M9 detector paper is attached properly. Detect and identify all liquid agents in the area that are within the capabilities of the M8 or M9 detector paper.
Always wear protective gloves when touching M9 detector paper. Do not get M9 detector paper in or near your mouth or on your skin. The M9 detector paper dye may cause cancer, but the risk is small because very little dye is used.
Note: M8 and M9 detector paper will not detect chemical agent vapors.
Note: M8 detector paper will not detect chemical agents in water, vapor, or aerosol form.
Note: When using M9 detector paper hot, dirty, oily, greasy surfaces, petroleum products and DS2 (decon solution 2) may give a false positive reading.
When using M9 detector paper ensure you use protective gloves to avoid contact with your skin.
If you are right handed, apply M9 detector paper to your right upper arm, left wrist, and right ankle. These are the locations you are most likely to come into contact with a chemical agent.
If left handed, M9 should be applied to left upper arm, right wrist, and left ankle.
If M9 detector paper turns pink, red, reddish brown, or purple, suspect the presence of chemical agents and take appropriate protective measures. Then confirm with M8 detector paper or preferably with M256 kit.
During night operations, white light is required to properly read M9 detector paper.
To use, tear a sheet of M8 detector paper from the booklet, using a stick, cleaning rod, etc. poke through the paper for your protection to avoid contact with suspected agent.
Dab or blot paper on suspected surface. Do Not rub paper against surface because false positive red streaks are produced.
M8 detector paper reacts to three types of chemical agents:
V-Type Nerve Agents Dark Green
G-Type Nerve Agents Yellow
Blister Agents Red
Note: During night operations, white light is required to properly read M8 detector paper.
Answer: Red, Reddish brown, Pink, Purple
Answer: Right upper arm, left wrist, right ankle
Answer: V-type Green, G-type Yellow, Blister Red
Answer: Use a stick or cleaning rod to poke through paper to avoid direct contact, ensuring to dab or blot not rub.
