When dealing with hazardous vapors at an incident scene, which color pages in the ERG provide evacuation distances?

The correct reference to evacuation distances for hazardous vapors in the Emergency Response Guidebook (ERG) is indeed found in the green pages. These pages are specifically designated for guidance related to toxic inhalation hazards, which include information on potential distances for evacuation based on the type of chemical involved.

The green pages provide information on safe distances that responders and the public should maintain to avoid exposure to harmful compounds. This is crucial for ensuring the safety of both emergency personnel and civilians in the vicinity of a hazardous materials incident.

On the other hand, the other color pages serve different purposes: the red pages provide information on specific incidents and the appropriate emergency response actions, while the blue pages are a general index for identifying hazardous materials. The yellow pages list dangerous goods in numerical order by the UN/NA numbers but do not specifically address evacuation distances. Understanding the specific functions of each section within the ERG is crucial for effective incident management and ensuring the safety of everyone involved.
