What is the purpose of M8 and M9 paper?

The purpose of M8 and M9 paper is specifically to detect chemical agents. M8 paper is designed to identify specific types of liquid chemical warfare agents, such as nerve agents and blister agents, by changing color when it comes into contact with these substances. M9 paper serves a slightly different function; it acts as a general indicator of the presence of a toxic chemical agent, changing color upon contact without the specificity provided by M8 paper.

These detection papers are crucial for ensuring the safety of personnel in combat situations where chemical agents may be used. By rapidly identifying the presence of these hazardous substances, military personnel can take appropriate protective measures and respond effectively to protect themselves and others, which underscores the strategic importance of M8 and M9 paper in chemical defense protocols.
