What does the yellow section of the ERG provide information about?

The yellow section of the Emergency Response Guidebook (ERG) is specifically designed to provide information on hazardous materials, which are organized alphabetically by their chemical name or material. This allows first responders to quickly locate and access critical data related to a specific hazardous material they may encounter during an incident. Each entry includes the material's identification number along with essential details like its properties, potential hazards, and recommended response actions.

The other options pertain to other aspects of emergency response planning and procedures but do not accurately represent the focus of the yellow section. Emergency evacuation procedures are typically found in other sections designed for overall incident management. Personal protective equipment recommendations can be found in the blue section and specific guidance on protective measures tailored to particular threats. The incident command structure is addressed in various chapters that focus on the overall management of emergency incidents rather than in the numerically organized materials section.
