Which of the following describes the High level FEMA marking?

• A. High- Square 2' x 2' with no marks
• B. High- Circle
• C. High- Triangle
• D. High- Square with "X" in middle

Answer: (D)

In the FEMA marking system used on collapse sites, the level of priority or importance is conveyed with simple shapes and a cross. The high level mark is represented by a square with an X in the middle. The cross through the square makes the message unmistakable and quickly readable by incoming teams and incident command, signaling a high-priority situation that needs attention. A plain square, a circle, or a triangle would not communicate the same high-priority status, and a square with no marks would convey nothing specific. So the square with an X in the middle is the standard way to indicate a high-level FEMA mark.
