Which of the following is NOT listed as a type of emergency response incident?

• A. Major accidents
• B. Terrorist use of CBRN materials
• C. Natural disasters
• D. Pandemic influenza

Answer: (C)

Emergency response incident types are categories planners use to organize rapid, coordinated actions. The listed groups—major accidents, terrorist use of CBRN materials, and pandemic influenza—are singled out because they represent events with the potential for widespread harm, complex hazards, and multi-agency response needs, requiring specialized coordination and rapid decision-making. Natural disasters, while they clearly require substantial response, are not included in this specific set of incident types, as they’re typically treated under separate disaster-management categories. So natural disasters are the one not listed here.
