There are three major elements to CBRN Passive Defense measures. Based on the criteria described, what is this situation describing? 'Taking protective actions in advance based on the immediacy and nature of the threat. These actions could include increased MOPP levels and actions taken in advance to protect aircraft and equipment from contamination.'

• A. Contamination Avoidance
• B. Decontamination
• C. Containment
• D. Recovery

Answer: (A)

Contamination Avoidance. The scenario centers on taking protective actions before any contamination occurs, based on how immediate and what kind of threat is present. Raising protective postures such as MOPP levels and taking steps to shield aircraft and equipment from potential contamination are preventive measures designed to minimize exposure. This is different from decontamination, which happens after exposure to clean equipment or personnel; from containment, which aims to stop the spread once contamination has occurred; and from recovery, which focuses on restoring operations after an incident.
