When encountering a substance, what group should one reference for information on immediate hazards?

• A. Blue Pages
• B. Yellow Pages
• C. Green Pages
• D. Orange Pages

Answer: (D)

The correct reference for information on immediate hazards when encountering a hazardous substance is the Orange Pages. These pages are part of the Emergency Response Guidebook (ERG) and provide essential information about specific hazardous materials, including their immediate health hazards, protective measures, and emergency response protocols.

When responders are faced with a hazardous situation, the Orange Pages help them quickly assess the risks associated with the substance they are dealing with. This information is vital for ensuring the safety of both the responders and the public, as it outlines necessary precautions and emergency actions.

In contrast, the other pages serve different purposes:

• The Blue Pages typically provide guidance on the proper response to specific incidents or accidents, focusing more on procedural aspects.

• The Yellow Pages are used for identifying hazardous materials by their UN (United Nations) number, which helps locate detailed information about a specific chemical.

• The Green Pages usually contain general information about emergency response procedures for specific types of incidents.

Therefore, the function of the Orange Pages in highlighting immediate hazards makes this choice the most relevant when handling hazardous substances.
