In the orange bordered pages initial isolation and protective action distances are provided under public safety. For those substances that are toxic inhalation hazard,s they are highlighted in the yellow and blue bordered pages and their evacuation distances are located in the green bordered pages.
Turn to the orange section of the Emergency Reponse Guidebook (ERG).
They are in the green section, Table of Initial Isolation and Protective Action Distances.

Green-bordered
The yellow pages of the Emergency Response Guidebook (ERG) provide initial isolation and protective action distances for specific hazardous materials. These distances help first responders to quickly identify safe distances to protect themselves and the public in case of a chemical spill or release.
Green section, Table of Initial Isolation and Protective Action Distances.
This section contains a table which lists, by ID number, TIH materials, including certain chemical warfare agents, and water-reactive materials which produce toxic gases upon contact with water. The table provides two different types of recommended safe distances which are "Initial isolation distances" and "Protective action distances."
100 Feet
Entries highlighted in green can be found listed by ID number in the Initial Isolation and Protective Action Distances section ( Green Section ) at the back of the ERG. All listings in this section are considered Toxic Inhalation Hazards (TIH) and have suggested isolation and protective distances following each (TIH) entry. The section is made up of two tables with Table 1 listing all (TIH)s including those that react when spilled in water. Table 2 lists only (TIH)s that produce large amounts of (TIH) Gases when spilled in water plus the gas produced during the reaction.
B. During the first 30 minutes of an incident.
