Which step in the OEHSA process follows intelligence and, generally includes a written and graphical depiction of OEH threats and how people come into contact with the threats?

• A. Conceptual Site Model (CSM)
• B. Site Reconnaissance
• C. Routine and Specialized Assessment
• D. Reassessment

Answer: (A)

The step after gathering intelligence is the Conceptual Site Model. It creates a written and graphical depiction of OEH threats and how people come into contact with them, stitching together sources, media, exposure routes, and receptors into a single coherent picture. This model uses both diagrams and narrative to show where hazards originate, how they move through the environment, what routes people might take to contact them (such as inhalation, ingestion, or dermal contact), and which populations are at risk. Why this is the best fit: it explicitly produces a combined visual and textual representation of threats and exposure pathways, which guides prioritization for further investigation and risk assessment. It also helps reveal gaps in knowledge so next steps—like field reconnaissance or targeted testing—can be focused and efficient. Site reconnaissance is about the actual field observation and data collection from the site, which comes after forming an initial understanding. Routine and specialized assessments are the measurements and analyses used to quantify hazards and exposures. Reassessment updates the model as new information becomes available.
