When does the site survey team decontaminate during dismounted CBRN search and survey reconnaissance?

The site survey team decontaminates during the Clear phase because this is when the team ensures that the area is free from hazardous materials and is safe for further operations or personnel entry. The Clear phase focuses on identifying contamination and ensuring that the site is secure. Decontamination during this phase is crucial to prevent the spread of chemical, biological, radiological, or nuclear contaminants and to protect the safety of the personnel involved in the operation.

In contrast, during the Sample phase, the primary emphasis is on taking samples of suspected contaminants for analysis, while the Collection phase concentrates on gathering evidence and materials after contamination has been identified. The Recovery phase typically involves actions taken after the immediate threat has been assessed and does not prioritize onsite decontamination as a critical mission requirement. Therefore, the Clear phase is the appropriate stage for decontamination activities within the context of CBRN reconnaissance operations.
