Which document is used to guide hazmat incident initial actions and boundary decisions?

• A. International Fire Service Training Association Training Manual.
• B. National Fire Protection Association Guidebook.
• C. Emergency Response Guidebook.
• D. Environmental Protection Agency.

Answer: (C)

The key idea is having a quick, field-ready reference that translates hazmat knowledge into immediate actions and safe boundaries. The Emergency Response Guidebook is designed for that purpose. It lets responders identify a material from placards or shipping papers and then provides step-by-step guidance for the first actions to take, including how to control the scene and protect people. It also gives the recommended isolation or boundary distances to minimize exposure and determine whether to evacuate, shelter-in-place, or call for specialized resources. The other documents are more general training materials or regulatory in nature and do not serve as the primary on-scene guide for hazmat actions and boundary decisions.
