Which kit is designed to detect nerve, blister, cyanide (blood), or lewisite chemical warfare agents in water?

• A. Water Quality Test Kit
• B. The M-272 Water Test Kit
• C. Nerve Agent Detector Kit
• D. VOCs Test Kit

Answer: (B)

In field detection of chemical warfare agents in water, you need a kit that can screen for multiple agent classes in one test. The M-272 Water Test Kit is designed specifically for this purpose, offering rapid detection of several CW agent types in water—nerve agents, blister agents, cyanide-based blood agents, and lewisite. It uses field-compatible colorimetric indicators that produce a visible change when these agents are present, allowing quick screening without complex equipment.

Other kits shown target different purposes: a Water Quality Test Kit focuses on general water quality parameters (like pH, chlorine, hardness) rather than CW agents; a Nerve Agent Detector Kit would detect only nerve agents and miss other classes; a VOCs Test Kit looks for volatile organic compounds, not chemical warfare agents.
