AWARENESS

O SHA - Hazardous chemical EPA - hazardous substance DOT - Hazardous material CBRNE - Chemical Biological Radiological Nuclear Explosive Evacuation and sheltering in place factors - Materials involved Population threatened Responders resources and capabilities Time factors involved Current and predicted weather Ability to communicate with the public SAFE - Safety always Analyze all info Focus on FRO Enthusiasm Truck - Bill of lading In cab near driver seat or with driver Air - Air bill With pilot in cockpit Raik - Waybill and consist With conductor Vessel - Dangerous cargo manifest On bridge Hot zone - Exclusion Warm zone - Contamination reduction Cold zone - Support

Objectives of perimeter and control zones - Control entry points Control perimeter Control access Major elements of hazmat problems - Volume of hazardous material Variety of hazardous material Widespread presence of hazardous material Human factor 3 primaries of hazmat events - Fire, health, and reactivity risks HAZWOPER - Hazardous waste operations and emergency response FED - 29 CFR 1910. State - Title 8 What 3 activities does HAZWOPER regulate? - Hazardous waste cleanup Operation of treatment, storage, and disposal facilities Emergency response to hazmat releases LEVELS of HAZWOPER - First responder awareness FRO Technicians Specialist IC Skilled support personnel Respond at safe distance - Uphill, upwind, upstream 6 ways hazmat can kill you - Toxicity Radioactivity Asphyxiation Explosion Fire And corrosion Three types of notifications to alert others of hazmat events - Mandatory notifications Resource request Report in conditions ICS general staff - Operations section Planning/ intel Logistics Financial/ admin
