HazMat/WMD Awareness Unit 2 slide 1 UNIT TWO Understanding Hazardous Materials

HazMat/WMD Awareness Unit 2 slide 2 Potential Outcomes TRACEM Thermal (Fire and/or Explosion) Radiological Chemical exposure Asphyxiation (Oxygen Deficiency) Etiological (Biological Hazards) Mechanical

HazMat/WMD Awareness Unit 2 slide 3 Thermal (Fire and/or Explosion) Heat from a fire or the heat released by a chemical reaction Extreme cold, such as liquefied gas or cryogenic liquids

HazMat/WMD Awareness Unit 2 slide 4 Radiological Alpha - Most damaging, but least penetrating Hazard – Internal Shielding – Paper, dead layer of skin, travels 1 to 2 cm in air +  Beta - Small particle; low penetration Hazard - Primarily external, but also internal Shielding - Plastic, safety glasses, travels several feet in air - --

HazMat/WMD Awareness Unit 2 slide 5 Neutron - Highly penetrating Hazard - External - most external dose due to gamma Shielding – plastic, water N Gamma / X - Highly penetrating Hazard - External - most external dose due to gamma Shielding - Lead, steel, concrete, thick layers of water  Radiological (cont.)

HazMat/WMD Awareness Unit 2 slide 6 Asphyxiation Oxygen Deficiency Chemical Reaction THE RELEASE OF CERTAIN PRODUCTS (I.E. NITROGEN) CAN DEPLETE THE OXYGEN LEVEL BELOW SURVIVAL LIMITS.

HazMat/WMD Awareness Unit 2 slide 7 Chemical Toxic or poisonous effects Destructive effects from the exposure of the chemical on human tissue

HazMat/WMD Awareness Unit 2 slide 15 Exposure to Hazards Acute Chronic Both types of exposures can have acute (immediate) and/or chronic (long term) effects.

HazMat/WMD Awareness Unit 2 slide 16 Terrorist Events Intentional release Secondary devices Inflict mass casualties

HazMat/WMD Awareness Unit 2 slide 17 Terrorist Chemical Agents Choking Agents Blood Agents Blister Agents Nerve Agents The symptoms of these exposures can range from a runny nose to rapid death and are considered to be available to terrorist groups worldwide.

HazMat/WMD Awareness Unit 2 slide 18 Emergency Medical Care Treatment only after emergency decon “Safety First”

HazMat/WMD Awareness Unit 2 slide 19 Emergency Decon If a rescue is attempted and is successful the victim and the rescuer should be flushed with copious amounts of water Strip their outer level of clothing await hazardous materials operations level responders to arrive THE RESCUER NOW BECOMES A VICTIM BECAUSE OF UNKNOWN HAZARD EXPOSURE!!!
