Which three methods can be used to determine the appropriate guide pages in the Emergency Response Guidebook (ERG)?

The correct choice involves using the UN/NA ID number, the name of the material, or a placard to determine the appropriate guide pages in the Emergency Response Guidebook (ERG). Each of these methods provides concrete information that helps responders quickly identify hazardous materials and access relevant safety information.

The UN/NA ID number is a crucial identifier assigned to hazardous substances and ensures that responders can locate specific data about that material quickly. This number is a standardized reference that enhances communication and accuracy in emergency situations.

The name of the material also serves as an immediate reference. It allows responders to cross-reference with the guides within the ERG, ensuring they have the correct information on handling procedures, potential hazards, and emergency response strategies.

The use of a placard, which is typically seen on transport vehicles carrying hazardous materials, acts as a visual cue that can assist responders in identifying the nature of the hazard. By quickly recognizing the placard symbols, responders can ascertain which guide to consult for tailored response actions.

Together, these three methods provide a reliable system for identifying hazards and formulating appropriate responses in emergency situations involving hazardous materials.
