  1. Hazardous Materials Response Henderson Fire Department Tactical Standard 6th Edition

  2. Objectives • Explain Operations Level responsibilities • Identify hazmat jurisdictional Incident Command responsibilities • Describe the 3 levels of hazmat incidents • Name the resources utilized to identify hazardous materials • Recognize common hazmat containers • Define isolation perimeter, initial isolation zone and protective action distance • Explain the 3 scene control zones • Describe defensive control actions

  3. Objectives continued • Identify the differences between gross decon, emergency decon, technical (formal) decon, and mass decon. • Define the 3 hazmat incident strategies • Explain the difference between immediate concerns and primary objectives • Identify the 9 DOT/UN Hazard classes • Define a polymerization reaction • Explain the management components of a hazmat incident • Utilize Hazmat IQ system

  4. Overview • Henderson Fire Hazmat Training • Hazmat Potential • Training Level • Incident Command Responsibilities

  5. Incident Levels • Level I Incident • HFD only • Level II Incident • Hazmat Team • Level III Incident • State or Feds

  6. Identifying Hazmat • Marking Systems • DOT/UN Marking System • NFPA 704

  7. DOT/UN Marking System • 9 Hazard Classes • 3 Packing Groups • Placards • Labels • 2 Tables • Identification Numbers

  8. NFPA 704 System

  9. Reportable Quantity (RQ) • 5 Categories • National Response Center (NRC)

  10. Information Resources • Hazmat IQ System (HMIQ) • Emergency Response Guidebook (ERG) • NIOSH Pocket Guide (NPG) • Cameo Chemical Software • WISER online • Material Safety Data Sheets (MSDS) • Shipping Papers

  11. Scene Control • Isolation Perimeter • Solids – 75ft • Liquids – 150ft • Gases – 330ft • Explosives – ½ mile (800 yards) • Initial Isolation Zone • Protective Action Zone • Hazard Control Zones • Hot, Warm, Cold

  12. Isolation Perimeter • Unknown Chemical • Solids – 75ft • Liquids – 150ft • Gases – 330ft • Explosives – ½ mile (800 yards)

  13. Initial Isolation Zone • ERG • Known Chemical • Less than 30 minutes & not on fire

  14. Protective Action Zone • ERG • Less than 30 minutes & not on fire • Evacuation • Shelter-in-place

  15. Hazard Control Zones • Hot • Warm (contamination reduction zone) • Cold Zone (support)

  16. Spill Control/Confinement • Absorption • Blanketing/Covering • Dike/Dam/Diversion/Retention • Vapor Suppression • Ventilation • Vapor Dispersion • Dilution • Dissolution

  17. Decontamination • 4 Types • Gross Decon • Emergency Decon • Technical (formal) Decon • Mass Decon (wet & dry)

  18. Gross Decon

  19. HFD Emergency Decon • HFD Emergency Decon Procedure Clothes, PPE & Equip. Entry Team Litter Team Cleaning Team Rescue Crew Victim Hot Zone Cold Zone Warm Zone

  20. HFD HFD Emergency Decon – Single Engine Entry Clothes, PPE & Equip. Rescue Crew Entry Team Cleaning Team Victim Hot Zone Cold Zone Warm Zone

  21. Technical (formal) Decon

  22. Mass Decon (wet) Cold Zone Warm Zone Hot Zone

  23. Mass Decon (dry)

  24. 3 Hazmat Strategies • Non-intervention • Defensive • Offensive *Note: Line-of-sight Rescue

  25. Immediate Concerns & Primary Objectives • Immediate Concerns (Ops level) • Isolate the area & deny entry • Evacuate or shelter-in-place • Dike/dam/divert runoff • Eliminate ignition sources • Cool tanks if appropriate • Primary Objectives (typically not Ops level) • Extinguish fires • Control gas or vapor clouds • Stop leaks (plug or patch) • Turn off valves

  26. Hazard Classes • Explosives • Gases • Flammable & Combustible Liquids • Flammable Solids, Dangerous When Wet & Spontaneously Combustible • Oxidizers and Organic Peroxides • Poisonous (Toxic) and Infectious • Radioactive • Corrosive • Miscellaneous

  27. Class 1 - Explosives • Identification (1.1 – 1.6) • Initial Isolation Perimeter = ½ mile • Explosive incident – no fire • Explosive incident – involving fire • Explosives detonated

  28. Class 2 Gases • Identification: 2.1, 2.2, 2.3 • Initial Isolation Perimeter = Gases 330ft • Bleve concern • Do not extinguish flame from relief valve • Flammable gas incidents • No fire or with fire • LPG leaks • Natural gas leaks in a home • Natural gas leaks outside

  29. Class 3 Flammable & Combustible Liquids • Identification • Initial Isolation Perimeter = Liquids 150ft • Flammable & Combustible Liquid Incidents • No fire • Involving fire

  30. Class 4 Flammable Solids, Dangerous When Wet, Spontaneous Combustibles • Identification: 4.1, 4.2, 4.3 • Initial Isolation Perimeter = Solids 75ft • Incidents Involving Class 4 Materials • No fire • Involving fire

  31. Class 5 Oxidizers and Organic Peroxides • Identification: 5.1 & 5.2 • Initial Isolation Perimeter = Solids 75ft, Liquids 150ft • Incidents Involving Class 5 Materials • No fire • Involving fire

  32. Class 6 Poisonous & Infectious Materials (Toxic) • Identification: 6.1 & 6.2 • Initial Isolation Perimeter = Solids 75ft, Liquids 150ft • Incidents Involving Class 6 Substances • No fire • Involving fire

  33. Class 7 Radioactive • 3 Types: Alpha, Beta & Gamma • Identification: Radioactive I, II, III • 2 Packaging Categories: Type A & B • Initial Isolation Perimeter = Start at 330ft – refer to ERG • Incidents Involving Radioactive Material • ALARA • No fire • Involving fire

  34. Class 8 Corrosives • Identification: pH, placard, research • Initial Isolation Perimeter = Solids 75ft, Liquids 150ft • Incidents Involving Corrosives • No fire • Involving fire

  35. Class 9 Miscellaneous • Identification: placard (black & white vertical stripes on top – solid white lower) • Initial Isolation Perimeter = Solid 75ft, Liquid 150ft, Gases 330ft

  36. Polymerization • Identification: • “P” after ERG guide number, • Presence of “=“ sign in formula, • Stated in Incompatibilities/Reactivities (NIOSH), • Heat gun (increasing temp) • Incidents involving a polymerization reaction • Isolate area & deny entry • Confirm polymerization • Identify material • Evacuate area

  37. Managing Hazmat Incident • Basic Response • Know your limitations • Dispatch information • Additional information • Resources • Pre-entry observation stop • On scene

  38. Hazmat IQ • Hazmat IQ PowerPoint located on SharePoint.
