Answer: (B)

The Emergency Response Guidebook is a quick-reference resource designed for first responders to hazardous materials incidents, providing guidance across several critical aspects of an emergency. It covers spills and leaks, helping responders identify the hazard, assess the scene, and outline containment and safety actions. It also includes information on evacuation and other protective actions, guiding decisions about when to evacuate or shelter in place based on the material and situation. Additionally, it offers first-aid and medical guidance for exposure, so responders can recognize symptoms and support decontamination and treatment. Because it supports multiple facets of an incident—containment, protective actions, and medical response—“All of the above” best reflects what the book contains.
