Which step in the OEHSA process focuses on considering information that is already known about a site to identify present and past factors that could have adverse health effects?

• A. Site Reconnaissance
• B. Pre-Deployment/Baseline Activities
• C. Routine and Specialized Assessment
• D. Conceptual Site Model (CSM)

Answer: (B)

This item tests how OEHSA uses information already known about a site to identify present and past factors that could have adverse health effects. Pre-Deployment/Baseline Activities concentrate on reviewing existing site information—historical land use, prior contamination data, past incidents, exposure histories, and previous assessments—to establish what hazards might be present before new work begins. This helps set a baseline for comparison, guides planning and prioritization of monitoring or sampling, and informs protective measures. It differs from site reconnaissance, which focuses on observing current conditions in the field; routine and specialized assessments, which collect new data on hazards; and the conceptual site model, which integrates all information into a framework linking sources, pathways, and receptors.
