GENERAL HAZMAT RESPONSE • SIZE UP • The process of gathering and analyzing information • STRATEGY • The general plan or course of action for preventing or reducing effects of an incident • TACTICS • The methods and tasks used to accomplish the selected strategy
GENERAL HM RESPONSESize Up • Obtain and Evaluate as much information as time permits • the identity of the material • the hazards associated with each material • effects on public, property and environment • air, land, surface water, groundwater • determine options for control or mitigation • determine and initiate safety measures.
GENERAL HM RESPONSESize Up • Brief description of incident • location, date, time, identity, habitation • Terrain and Site Conditions • accessibility, dispersion paths, sensitive areas • Present status and current participation • Status of communications • Current / impending weather conditions
GENERAL HM RESPONSESize Up • Offsite Reconnaissance • general layout of the site • note # of containers, building, impoundment • look for placards, labels, markings • look for vapors, clouds, run-off, dead animals • not an unusual odors • off site samples • interview people in the area
GENERAL HM RESPONSESize Up • On Site Survey • confirm earlier observations • #’s, types, quantities, locations, dispersion paths • labels, markings, tags • determine condition of material and container • assess behavior • foaming, vaporizing, corroding • consider air monitoring • approach from upwind • assume plume dispersion and set boundaries
GENERAL HM RESPONSESize Up • Determine Hazardous Nature of Material • Toxicity, Corrosivity, Radioactivity • Biological Hazards, Asphyxiating Hazards • Flammable Hazards, Explosion hazards • reactive or unstable materials, oxidizers • Type, Condition, Behavior of Containers • under stress from heat or fire • under stress from mechanical damage • under stress from chemical reactions
GENERAL HM RESPONSEStrategy • Based on priorities established by size up • rescue, life saving, responder safety • prevention/mitigation of explosion/fire • protection of property • protection of environment • potential for container failure (additional loss) • availability of resources and time • weather conditions
GENERAL HM RESPONSETactics • Life Savings Operations • Rescue • endangered persons • Evacuation • affected persons • needs to be an early decision, expect delays • Taking Shelter
GENERAL HM RESPONSETactics • Actions/Tasks employed to prevent or reduce the hazards of the chemcials • extinguishing fires, wetting areas • controlled burning/detonation • cooling containers, removing materials • plugging, patching original containers • dikes, berms, dams to confine materials to smallest possible area • chemical/physical methods
GENERAL HM RESPONSETactics • Prevent container Failure • Cool containers • use stress barriers • remove uninvolved materials • Contain Confine the Hazard • stop the leak • construct a barrier • remove ignition sources • controlled burning
GENERAL HM RESPONSETactics • Extinguish Fires • Use Proper Extinguishing Agent • Remove Fuel/Oxygen Supply • Let substance burn • Exposure Protection • PPE, CPC, Heat Stress, Decon • Tactical Withdrawal • Explosion Barriers
GENERAL HM RESPONSESummary • Size up the conditions present • Define the problems • Establish priorities • Evaluate possible courses of action • Determine if SOPs are applicable • Determine the best course of action • Put the strategy in operation • Review results and Revise
