What are three colors that M-8 paper can display?

The correct answer identifies the three colors that M-8 paper can display, which are yellow, green, and red. M-8 paper is a crucial tool used by Navy personnel to detect the presence of certain chemical agents. When exposed to these agents, the paper reacts and changes color, specifically indicating the type of agent present.

When the paper turns yellow, it indicates the presence of the nerve agent VX. A green color indicates that the agent is a nerve agent like G-series agents (e.g., Sarin or Tabun). Red signifies the presence of a blister agent, such as mustard gas. This functionality is critical for personnel to quickly identify threats and take appropriate precautions in a chemical, biological, radiological, or nuclear (CBRN) environment.

Understanding these color indicators is essential for effective chemical detection and response in the field, ensuring that the crew can differentiate between threats and act accordingly to protect themselves and manage damage control effectively.
