The M8 Chemical Detection Paper is used to detect the presence of liquid nerve (V and G types) and blister (H-) chemical agents.The M8 booklet is made up of (25) M8 sheets. Each page has three sensitive indicator dyes on the page. When a sheet is brought into contact with liquid that contains nerve or blister agents, the indicator dyes in the paper react with the agents to produce colored dots. The color indicates the type of agent present.There is a color chart inside the front cover of the booklet to help identify the agent detected. The colors indicate the following:
- Yellow – G-type Nerve Agents
- Red – H-type Blister Agents
- Dark Green – V-type Nerve Agents
M8 is used by tearing out a sheet and attaching it to clothing, or some other surface so it can be exposed to drops of chemical liquid splash. The paper may also be placed in contact with a liquid that is suspected of contamination. If colored spots appear, a chemical agent is present.M8 Paper cannot be used to detect chemical agents in water, or aerosol agents in the air. It does not detect vapors.
