Respiratory system problems were the National Center for Biotechnology Information most often reported injury. The respiratory irritants, ammonia, methamphetamine-related chemicals, and carbon monoxide were the chemicals more often associated with injuries. National Center for Biotechnology Information Most of the incidents with responder injuries were caused by human error or equipment failure. National Center for Biotechnology Information Firefighters wore personal protective equipment most frequently and police officers did so rarely. National Center for Biotechnology Information Police officers’ injuries were mostly associated with exposure to ammonia and methamphetamine-related chemicals. National Center for Biotechnology Information Most responders did not receive basic, awareness-level hazardous material training. Anhydrous Ammonia Illinois State Police What is HAZMAT? (Know this) “ Any biological agent and other disease-causing agent which after release into the environment and upon exposure, ingestion, inhalation, or Occupational Safety and assimilation into any person, either directly from the environment or indirectly by ingestion through food chains, will or may reasonably be Health Administration anticipated to cause death, disease, behavioral 29 CFR 1910.120 (a) (3) abnormalities, cancer, genetic mutation, ” physiological malfunctions (including malfunctions in reproduction) or physical deformations in such persons or their offspring… “ (Know this too) …any item or agent (biological, chemical, Institute of Hazardous Materials Management radiological, and/or physical), which has the potential to cause harm to humans, animals, or the environment, either by itself or ” through interaction with other factors. (Know this) A guidebook intended for use by f rst responders during the initial phase of a transportation incident involving hazardous materials/dangerous goods 2020 EMERGENCY RESPONSE GUIDEBOOK U.S. Department of Transportation A substance or material capable of posing an unreasonable risk to health, safety, or property when transported in commerce. The term includes hazardous substances, hazardous wastes, marine pollutants, elevated temperature materials, and materials designated as hazardous in the Hazardous Materials Table (see 49 CFR 172.101).

A hazard class is a group of hazardous materials that share dangerous characteristics. There are nine hazard classes based on the dangers posed in transportation. Class 1 – Explosives Class 2 - Gases Class 3 - Flammable and Combustible Liquids Hazardous Materials Classifications Class 4 - Flammable Solids Class 5 - Oxidizers and Organic Peroxides Class 6 – Poison (Toxic) and Toxic Inhalation Hazard Class 7 - Radioactive Class 8 - Corrosive Class 9 – Miscellaneous They are in the ERG. Hazard Classes & Emergency Response Guide HAZARD CLASS 1 EXPLOSIVES 1.1 - Mass Detonation Hazard 1.2 - Projection Hazard 1.3 - Predominantly a Fire Hazard 1.4 - No Significant Blast Hazard 1.5 - Very Insensitive Blasting Agents 1.6 - Extremely Insensitive Detonating Articles HAZARD CLASS 2 GASES 2.1 - Flammable 2.2 - Non-Flammable 2.3 - Poisonous Gas If I knew then what I know now, this video would never have been taken. I could have died. – Joel Hershberger HAZARD CLASS 3 FLAMMABLE HAZARD CLASS 4 4.1 - Flammable Solids 4.2 - Spontaneously Combustible 4.3 - Dangerous When Wet FLAMMABLE HAZARD CLASS 3 HAZARD CLASS 4 HAZARD CLASS 3 HAZARD CLASS 4     HAZARD CLASS 5 OXIDIZERS 5.1 - Oxidizers 5.2 – Organic Peroxides HAZARD CLASS 5 OXIDIZERS A group of chemicals that do not burn on their own, but when in combination with other chemicals may cause them to burn or burn at a higher-than-normal temperature. These chemicals can cause materials that would not ordinarily catch fire to begin to burn readily. HAZARD CLASS 6 POISON 6.1 - Poisonous 6.2 – Infectious Substances TOXIC TOXIC I H “Police officers’ injuries were mostly associated with exposure to ammonia and methamphetamine-related chemicals." GREEN HIGHLIGHTS = TOXIC INHALATION HAZARD TOXIC INHALATION HAZARD HAZARD CLASS 7 RADIOACTIVE HAZARD CLASS 8 CORROSIVE HAZARD CLASS 9 MISCELLANEOUS HAZARD CLASS 8 CORROSIVE Chemical materials that may attack and destroy living tissue (such as skin). Some of these materials may also attack and destroy metals, glass, or plastics through chemical reaction. Please be back and ready to go at the agreed upon time! Weekend at CBRNE  Another way to break down hazard categories is with the acronym CBRNE CBRNE  Chemical  Biological  Radiological  Nuclear  Explosive CBRNE  This term takes the nine hazard classes and breaks them into groupings that are more useful to the first responder.  These definitions purposely do not address the additional hazardous threat caused by human actions, such as; active killer/shooter, suicide bombing or other mass casualty situations caused by human actions. It should by noted that in many of these cases, the response principals addressed here may be successfully applied. CHEMICAL HAZARDS Toxic/Poisonous Substances  Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism.  Toxic materials can come in solid, liquid and/or gas states.  The term toxic is synonymous with poisonous.

A guidebook intended for use by f rst responders during the initial phase of a transportation incident involving hazar dous materials/danger ous goods 2020 EMERGENCY RESPONSE GUIDEBOOK NATIONAL INCIDENT MANAGEMENT SYSTEM Purpose and Directive for NIMS 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— regardless of cause, size, location, or complexity—in order to reduce loss of life, property and harm to the environment. Purpose and Directive for NIMS Purpose/Motivation (FEMA) The NIMS is the essential foundation to the National Preparedness System (NPS) and provides the template for the management of incidents and operations in support of all five National Planning Frameworks. Benefits of NIMS  Unified approach – all responders on the same page  Standardized command structure  Emphasis on preparedness  Mutual aid  Resource management  Flexible and standardized Components of NIMS   Command and Management  Incident Command System driven  Includes Multiagency Coordination System (MACS) Preparedness  Proactive, not reactive  Resource Management  Communications and Information Management  Based on the concepts of interoperability, reliability, scalability, portability, and resiliency and redundancy  Ongoing Maintenance and Management  NIMS Integration Center (NIC)  Supporting Technologies INCIDENT COMMAND SYSTEM (ICS) WHAT IS YOUR PLACE WITHIN IT? Incident Command System 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. Purpose of the ICS Used for agencies to be able to work together much more efficiently during an incident. Incident Command System Integrated organizational structure A system used to coordinate emergency preparedness and incident management among various federal, state, and local agencies. ICS as a part of NIMS A standardized on-scene emergency management of resources during incidents. The ICS model is used by jurisdictions and agencies, both public and private, to organize field-level incidentmanagement operations. Do you understand the difference between NIMS and ICS yet? NIMS History The NIMS is the organization through which disaster management is coordinated. Designed after the World Trade Center attacks in September 2001 and implemented starting in 2005, NIMS is designed to prepare for, prevent, and manage response to emergency and disaster situations, and to coordinate emergency response disaster responders on the local, state and federal levels. Do you understand the difference between NIMS and ICS yet? ICS History The ICS is a personnel management structure through which disaster response is controlled. ICS was developed by the State of California as a method by which earthquakes and other emergencies could be handled efficiently. Flexibility is a main tenet of ICS. When properly implemented, the system allows the development of a command chain of any size that can include government agencies and non-governmental organizations alike. Do you understand the difference between NIMS and ICS yet? Interaction NIMS offers training to disaster response personnel in using the ICS. ICS provides a standardized framework through which various agencies can coordinate command in a disaster situation. In the event of a disaster, NIMS interacts with agencies responding to the disaster as part of the ICS chain of command. QUESTIONS? Please contact me at (512) 974-0240.
