Damaged structures are evaluated and labeled based on the FEMA marking system. There are 3 levels, what are they? (Risk and shape)

• A. Low- Square 2' x 2'; Medium- Square with one diagonal line; High- Square with "X" in middle
• B. Minor- Circle; Moderate- Triangle; Severe- Rectangle
• C. Level One- Square; Level Two- Circle; Level Three- Diamond
• D. Tier A- Square; Tier B- Diamond; Tier C- Cross

Answer: (A)

Understanding this question starts with how FEMA communicates damage and risk at a collapse site. The marking system uses a simple visual code on the structure to indicate how safe or dangerous it is for responders to approach or enter.

A plain 2-foot by 2-foot square represents a low risk: the structure is considered relatively stable and hazards are minimal. Adding a diagonal line through the square signals a moderate risk: hazards exist, and entry may be possible but requires caution and precautions. A square marked with an X denotes the highest risk: serious instability or danger, and entry is typically restricted until stabilization or further assessment is done.

So this option aligns with the standard FEMA marking scheme, using the size 2' x 2' square as the baseline and progressively adding lines to convey increasing danger. The other patterns—using circles, triangles, rectangles, or different tier names—do not match FEMA’s agreed-upon marks, which is why this one is correct.
