A first responder should use the Table of Isolation and Protective Action Distances during hazardous materials incidents, particularly when assessing the potential impact of a release of toxic substances. This table helps determine safe distances for evacuation and protective actions based on the specific hazardous material involved, its quantity, and the prevailing environmental conditions. It is crucial for ensuring the safety of both responders and the public in the vicinity of the incident.
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.
The Table of Initial Isolation and Protective Action Distances provides specific guidance for emergency responders on the distances that should be maintained from hazardous materials during an incident. It outlines recommended isolation zones and protective action distances based on the type and quantity of the substance involved, helping to ensure public safety and minimize exposure. This table aids in effective incident management and response planning in the event of chemical releases or spills.

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.
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."

B. During the first 30 minutes of an incident.
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.
To find protective distances if there is no fire at a hazardous materials incident, refer to the green section of the North American Emergency Response Guide.
The Emergency Response Guidebook (ERG) provides guidance for first responders during hazardous materials incidents. The specific section that lists hazmat emergency procedures is typically found in the "Table of Initial Isolation and Protective Action Distances" and the "Emergency Response Guide" section. This section includes instructions on how to handle different hazardous materials, including evacuation distances and protective measures. Always refer to the latest edition of the ERG for the most accurate and up-to-date information.
In the green section of the Emergency Response Guidebook (ERG), you will find information related to the initial isolation and protective action distances for specific hazardous materials. This section provides guidance on the recommended safety zones and evacuation distances for various incidents, helping responders determine how far to keep people away from the hazard. It is particularly useful for assessing risks during chemical spills or releases.
