ERG Yellow Section contains what type of information?

ERG Yellow Section contains what type of information?

• A. Chemical Names organized alphabetically
• B. UN ID numbers organized numerically
• C. Guide pages with information
• D. Table of evacuation and isolation distances

Answer: (B)

The Yellow Section is designed as a numeric index keyed by UN identification numbers. This lets responders quickly locate the exact substance using the UN number found on labels or shipping papers, then access the initial emergency information tied to that UN entry. Since UN numbers are universal identifiers for hazardous materials, organizing the yellow section in numerical order supports fast, accurate lookup and immediate guidance on hazards and initial actions to take at the scene. Other organization methods, like alphabetizing by chemical name, would slow down identification, which is why this numeric UN-number arrangement is used.
