End the Exposure
The "__________" is a systematic, proactive approach to guide departments and agencies at all levels of government, nongovernmental organizations, and the private sector to work together seamlessly and manage incidents involving all threats and hazards—regardless of cause, size, location, or complexity—in order to reduce loss of life, property and harm to the environment.

"____________" - management system designed to enable effective and efficient domestic incident management by integrating a combination of facilities, equipment, personnel, procedures, and communications operating within a common organizational structure.
Incident Command System (ICS)
What is the purpose of the ICS?
Used for agencies to be able to work together much more efficiently during an incident.
True or False: NIMS is a response plan.
False
Study Notes
Hazardous Materials
- A hazardous material is a substance or material capable of posing an unreasonable risk to health, safety, or property when transported in commerce.
- A hazardous class is a group of hazardous materials that share dangerous characteristics.
Hazard Classes
- The United States Department of Transportation (DOT) identifies 9 hazard classes.
Hazardous Materials Definitions
- A simplified form of definition for hazardous materials is "chemical and biological substances that pose a risk to human life".
- CBRNE stands for Chemical, Biological, Radiological, Nuclear, and Explosive materials.
Hazard Class 1-9
- Hazard class 1: Explosives
- Hazard class 2: Gases
- Hazard class 3: Flammable liquids
- Hazard class 4: Flammable solids
- Hazard class 5: Oxidizers
- Hazard class 6: Toxic substances
- Hazard class 7: Radioactive materials
- Hazard class 8: Corrosive materials
- Hazard class 9: Miscellaneous hazardous materials
Hazardous Materials Types
- Toxic materials: materials that may cause injury or death to living organisms
- Acute effects: short-term, high-dose events with harmful consequences
- Chronic effects: long-term, low-dose exposure with harmful consequences
- Flammable materials: materials that have a high hazard due to ease of ignition, high burning temperature, or difficulty in extinguishment
Hazardous Materials Examples
- Gasoline, propane, and magnesium are examples of flammable materials
- Oxygen, hydrogen peroxide, and halogens are examples of oxidizers
- Ammonium hydroxide and Sodium hydroxide are examples of corrosive materials
- Foot and Mouth Disease (FMD), Exotic Newcastle Disease (END), and Classical Swine Fever (CSF) are examples of biological substances
CBRNE
- CBRNE materials include chemical, biological, radiological, nuclear, and explosive materials
- The study of adverse effects of chemicals or physical agents on living organisms is called toxicology
- The level to which it is believed a worker can be exposed day after day for a working lifetime without adverse health effects is called the Threshold Limit Value (TLV)
- A document that contains information on the potential health effects of exposure to chemicals, or other potentially dangerous substances, and on safe working procedures when handling chemical products is called a Material Safety Data Sheet (MSDS)
Safeguarding Lives during CBRNE Events
- The RAIN Principle is used to safeguard lives during a CBRNE event: Recon, Avoid, Isolate, and Notify
- Staying uphill or upwind from a CBRNE incident is an example of the RAIN Principle
- The first Decontamination Concept an officer should concern themselves with is the removal of contaminated clothing and personal protective equipment (PPE)
Incident Management
- The National Incident Management System (NIMS) is a systematic, proactive approach to guide departments and agencies at all levels of government, nongovernmental organizations, and the private sector to work together seamlessly and manage incidents involving all threats and hazards.
- The Incident Command System (ICS) is a management system designed to enable effective and efficient domestic incident management by integrating a combination of facilities, equipment, personnel, procedures, and communications operating within a common organizational structure.
- The purpose of the ICS is to reduce loss of life, property, and harm to the environment.
