The section of the Emergency Response Guidebook (ERG) that utilizes a color-coded system for identifying materials is indeed the yellow section. This section is particularly focused on hazardous materials classified by their UN (United Nations) numbers. By using this system, first responders can quickly locate and identify substances present at an incident scene.

The inclusion of a specific color-coded approach enhances the efficiency of emergency responders by allowing them to effectively match the UN number with the corresponding material and its associated risks, response recommendations, and protective actions. This system is designed to facilitate rapid action under stressful conditions, making the yellow section a vital resource in hazardous material incidents.

In contrast, the other sections of the ERG serve different functions: the green section provides information on evacuation and isolation distances; the red section outlines a list of dangerous goods; and the blue section is organized by the names of dangerous goods, which doesn’t employ a color-code format in the same way as the yellow section does.
