Which activities are part of a basic CBRN hazard assessment for a facility?

• A. Plan and execute a drill
• B. Stockpile medicines
• C. Identify hazards, assess likelihood and consequences, map exposure pathways, determine protective measures
• D. Define decontamination efficacy and dwell time

Answer: (C)

At the heart of a basic CBRN hazard assessment is systematically evaluating what could threaten the facility and how to reduce that risk. You start by identifying potential hazards—the CBRN agents, release scenarios, and pathways that could affect people and operations. Then you assess both the likelihood of those scenarios occurring and the potential consequences if they do occur, so you can prioritize mitigation. Next, you map exposure pathways to understand exactly how people or systems could be exposed—through inhalation, dermal contact, ingestion, or contaminated surfaces—so you know where controls are most needed. Finally, you determine protective measures to lower risk, choosing appropriate controls such as engineering changes (ventilation, containment), administrative procedures (training, access controls), and personal protective equipment. Other activities fall into separate parts of preparedness and response. Planning and executing a drill tests readiness, not the intrinsic assessment of hazards. Stockpiling medicines relates to medical logistics and readiness, not identifying hazards or protective strategies. Defining decontamination efficacy and dwell time focuses on post-exposure cleanup and response operations rather than the initial hazard assessment.
