In CBRN sampling, which role typically determines which sampling supplies are required?

• A. Field Supervisor
• B. Safety Officer
• C. Sample Collector
• D. Lab Technician

Answer: (C)

In field sampling for CBRN work, the person actually collecting the samples is the one who determines what supplies are needed. They execute the sampling plan and handle the real-world conditions, so they know exactly what containers, preservatives, swabs, filters, absorbent materials, PPE, labels, chain-of-custody forms, and decontamination supplies are required for each matrix and method. The field supervisor provides overall oversight and safety, but doesn’t typically decide the specific kit contents. The safety officer focuses on risk assessment and protective measures, not the exact sampling supplies. The lab technician designs and performs the analysis after sampling, so they’re not selecting field collection materials.
