Which type of material would you NOT expect to find in the yellow-bordered section of the ERG?

Answer: D — Non-hazardous materials

The yellow-bordered section of the Emergency Response Guidebook (ERG) is specifically designed to address materials that pose substantial risks in a hazardous materials incident. This section focuses on hazardous materials that are classified as either flammable or reactive, including corrosive substances, flammable gases, and liquids with flash points that can create significant risks during emergencies. Non-hazardous materials would not be included in this section because they do not pose a threat to health, safety, or the environment. The purpose of separating hazardous from non-hazardous materials is to ensure first responders can quickly access and utilize the appropriate procedures for responding to incidents involving dangerous substances. Thus, the inclusion of non-hazardous materials would defeat the primary aim of the yellow-bordered section, which is to provide guidance on handling and mitigating the effects of hazardous materials.
