The M256A1 is a Chemical Warfare (CW) vapor detection kit for Nerve, "H" series Blisters, Lewisite and Blood Agents. It has been used by our ground troops as well as EOD and NBC Teams for decades. Due to the compactness of the kits and ease of use, ground troops are able to carry several of these on their person, allowing them to perform rapid area surveys to detect the release of a CW agent. The 256 kit does not contain any means for decontamination. only to detect the presence of the agent.
When M8 paper comes into contact with liquid "G" series Nerve agents, the paper will turn a yellow to Amber color. When exposed to liquid VX Nerve agent, the paper turns green. When exposed to liquid "H" Series Blister agent, the paper turns red. These are the only three agents the M8 paper will detect.
These kits are brand new and being sold as collectors items only
