Which organization developed the building marking system?

• A. FEMA
• B. OSHA
• C. NFPA
• D. ANSI

Answer: (A)

The reason this marking system exists is to give responders a quick, universal way to communicate interior conditions of a damaged building from the outside, so teams don’t duplicate work or miss hazards. It was developed by FEMA—the Federal Emergency Management Agency—for US&R operations. FEMA’s system standardizes marks (often placed on doors or exterior walls) that convey essential information such as search status, number of victims found, hazards present, and the time of the mark. This shared language across agencies improves coordination and safety during complex collapse operations.

Other organizations focus on different areas of safety and standards (for example, OSHA on workplace safety, NFPA on fire and rescue standards, ANSI on general standards). The building marking system used in US&R is specifically FEMA’s creation, which is why it’s the best answer.
