o Biological Toxins (Ricin, botulinum toxin, etc.)
o Describe differences between acute and chronic exposures

6

Define infectious materials

Human Pathogens
o Plant and Animal Pathogens (instructor should explain economic significance and

o Principals of Infection Control

7

What are human pathogens

(define “pathogen” as a “disease-causing organism”)

Incident command system

22

What is the initial assessment and response at an incident

Observations (Odors, noises, wind direction, placards, signs, etc.)
Assessment (Hazard level, casualties, need for additional resources, etc.)
Plan (Response, exit strategy, precautions, etc.)
Communicate (Dispatch, casualties, good Samaritans, etc.)
Respond (Establish perimeter, first aid, enable ICS, etc.)
