Upon finding a 4-digit ID number on an orange panel at a hazardous material incident, where should guidance be sought in the Emergency Response Guidebook?

• A. In the green section
• B. In the yellow section
• C. In the blue section
• D. In the orange section

Answer: (B)

The correct approach when discovering a 4-digit ID number on an orange panel is to consult the yellow section of the Emergency Response Guidebook. This section is specifically designed to provide information based on the unique identification numbers associated with hazardous materials. These numbers correlate with specific chemicals or materials, allowing responders to quickly identify the substance involved in the incident.

The yellow section guides users through the process of understanding the identified material’s properties, associated hazards, and recommended initial actions to take. This is critical for ensuring safety and effective response in a hazardous materials situation.

Reference materials that might seem relevant, such as the orange section, primarily offer general response guides on specific hazards and protective actions but do not focus on identifying materials through their ID numbers. This distinction highlights why the yellow section is the appropriate resource for this situation.
