If a portion of a contaminated area is marked with a single sign, what is the likely deficiency?

• A. It would not meet the minimum number of markers
• B. It would be sufficient for identification
• C. It would cause no impact
• D. It would confuse forces

Answer: (A)

The important idea here is that a contaminated area needs a sufficient number of markers to clearly define its boundaries and ensure reliable recognition by responders. A single sign does not meet the required minimum, so the marked area isn’t clearly delineated and could be missed, damaged, or misinterpreted. This weakens identification and safe control of entry and exit, increasing risk to personnel. The other options imply the marking would be adequate or have no effect, but the core deficiency is simply not meeting the minimum number of markers.
