If given a chemical name, which color section in the ERG would you use to find the guide page?

In the Emergency Response Guidebook (ERG), the blue section is utilized for locating the guide page based on the provided chemical name. This section contains an alphabetical listing of hazardous materials, which allows responders to quickly identify the specific substance they are dealing with. Once the chemical name is located in this section, responders can turn to the corresponding guide number to find detailed information on safety measures, initial response actions, and potential hazards associated with that chemical.

The other sections of the ERG serve different purposes: the red section outlines potential hazards based on the UN (United Nations) number, the yellow section organizes materials by their numerical classification, and the green section provides information related to evacuation distances for specific hazardous materials. Therefore, based on the need to find a guide page using a chemical name, the blue section is the appropriate choice.
