32. Summary • Hazardous materials incidents pose significant hazards to first responders. Awareness-Level first responders must know their primary responsibilities and their limitations in dealing with hazardous materials incidents. • Hazardous materials are regulated in both the U.S. and Canada by a number of agencies. (1 of 2) Awareness Level

33. Summary • Hazardous materials may be classified by their hazard. The NFA and NFPA have categories of hazardous materials classifications. • Hazardous materials pose significant health hazards that can range from minor to severe and even fatal. • Hazardous materials can enter the body through a number of routes.
