M8 Chemical Detection Paper

M8 is a three‑colour chemical detection paper used to identify the family of liquid nerve (V‑ and G‑type) and blister (H‑series) agents on contact. Each sheet contains indicator dyes that change to characteristic colours when blotted onto a suspect liquid, allowing a quick read in the field without instrumentation. The booklet format is simple to carry and deploy at an incident scene or entry control point.

Why teams choose M8

• Identify the agent family (not just “present/absent”) via distinct colour changes for V, G and H agents.
• Book of sheets for rapid issue to team members; designed to blot, not rub—minimising spread of contamination.
• Compact and robust for patrol carry, checkpoints and hot‑zone screening.

How it works

Blot the paper onto a visible liquid or surface droplet, then compare the colour to the chart inside the booklet cover. Typical reactions: yellow‑gold (G nerve), dark green (V nerve), red‑pink (H blister).

Key details

• NSN: 6665‑00‑050‑8529.
• Use: identification of liquid CW agents on non‑porous surfaces; single‑use sheets in a 25‑sheet booklet (manufacturer format).

Typical applications

On‑scene liquid spills, contact‑trace verification at door handles or vehicle panels, and confirmation after an M9 tape alert.
