Role of Awareness Trained Personnel Recognize –Hazardous Materials using various clues. Isolate –the site using distances in the ERG –remove persons in the isolation area –Deny Entry to ALL unauthorized personnel
Role of Awareness Trained Personnel Isolate –Establish & Mark zones Police Barricades / Banner Tape Other personnel
Role of Awareness Trained Personnel Initial Isolation Distances –Use distances in Orange border guide for products not highlighted at al times. –Use distances in orange guides for all products on FIRE. –Use distances in Green border (Initial Isolation & Protective Action Section) if material is highlighted yellow or blue, not on fire, first 30 minutes.
Role of Awareness Trained Personnel Notify –Call for Help CFPD / MFD Haz-Mat Technicians Lake County Haz-Mat Team –Identify Survey Scene from a safe distance ID Material –Protective Action Do not place responders or others in danger.
Role of Awareness Trained Personnel Evacuation –Takes time –Start with people in most danger, expand downwind & crosswind. –Send evacuees to a specific location upwind. –Most desirable action to take if you have time.
Role of Awareness Trained Personnel Shelter-in-Place –Close all door & windows –Control ventilation systems –Use if evacuation would be greater danger –Not an option with explosive gases. Protective Action Distances –taken from DOT ERG
Know the PLAN Operate under SOG’s Use pre-plans, check off forms, other resources. Know your role as a Haz-Mat Awareness responder.
Incident Concerns Safety –Responders –Others –Environment Provide Medical Care –De-Con Eliminate Ignition Sources –Flares, vehicles, etc.
