What is the first step when using the Emergency Response Guidebook (ERG) with a UN/NA ID number?

• A. Contact local authorities for assistance
• B. Look up the material in the yellow pages
• C. Examine the material’s container for warnings
• D. Review the blue pages for specific hazards

Answer: (B)

The Emergency Response Guidebook (ERG) is designed to provide essential information for first responders dealing with hazardous materials incidents. When a responder encounters a situation involving a material with a UN/NA ID number, the correct initial step is to look up the material in the yellow pages of the ERG. This section is specifically set up to provide a quick reference to hazardous materials based on their identification numbers, which helps responders determine the appropriate response actions and hazards associated with the substance.

By starting with the yellow pages, responders can quickly access critical information regarding the specific material involved, including its properties, potential hazards, and necessary precautions to take. This foundational understanding is crucial for ensuring safety and effective management of the incident.

While contacting local authorities, examining containers, and reviewing specific hazards are also important aspects of managing hazardous materials incidents, they come into play after identifying the material and understanding its risks using the ERG. Thus, the yellow pages serve as the essential first step for responders in these scenarios.
