An Introduction To Hazardous Materials

  1. 1. An Introduction to Hazardous Materials The Brentwood Fire Department’s Citizen Fire Academy Class of 2004
  2. 2. Your Instructor LT Scott Ellis Hazardous Materials Technician
  3. 3. Agenda The Hazardous Materials Problem Brentwood’s Response to Hazardous Materials The Hazardous Materials Response Process
  4. 4. The Hazardous Materials Problem Approximately 50% of all hazardous materials that are released are hydrocarbon based fuels – gasoline, diesel, natural gas, propane, et cetera Approximately 25% of all hazardous materials that are released are commonly encountered chemicals
  5. 5. Common Chemicals Explosives Flammable Solids Acids Bases Poisons Radioactive The remaining 25% are truly exotic of which we have little experience.
  6. 6. What are HazMat’s? U.S. DoT categorizes HM’s into 9 different categories: 1 – Explosives 2 – Flammable gases 3 – Flammable and combustible liquids 4 – Flammable solids 5 – Oxidizers 6 – Poisons 7 – Radioactive 8 – Corrosives 9 – “Other Regulated Materials” or ORM’s
  7. 7. Explosives
  8. 8. Flammable Gases
  9. 9. Flammable and Combustible Liquids
  10. 10. Flammable Solids
  11. 11. Oxidizers
  12. 12. Poisons
  13. 13. Radioactive
  14. 14. Corrosives
  15. 15. ORM’s
  16. 16. Unique Situations in Brentwood Very little industrial I-65 Three railroads - CSX Approach for Nashville International - FedEx shipments Household hazmats Mutual Aid – County HM Group
  17. 17. Household HazMat’s Pesticides Fertilizers Ammunition Cleaning products Pool chemicals Fuels (gasoline, alcohols, propane)
  18. 18. Brentwood’s Response to Hazardous Materials Three components – talent, tools, and techniques… Talent - Departmental Hazardous Materials Response Team Tools - Departmental Hazardous Materials Equipment and Assets Technique – Departmental Hazardous Materials Operational Guidelines
  19. 19. BFD’s HazMat Response Team Sixteen members All members are HazMat Technicians Some are TEMA certified – remainder are OSHA certified by U.S. EPA All have basic WMD training Some have specialized WMD training, to include chemical and biological weapons, explosives, and EMS response to WMD
  20. 20. Williamson County HazMat Response Group Co-lead by Deputy Chief Todd Horton, Franklin Fire Department and Lieutenant Russell Peterson, Brentwood Fire Department Six person Management Team includes Operations Officer, Safety Officer, and Medical Officer Ten person Technical Support Team includes Chemical, Biological, Radiological, Nuclear, and Explosives Specialists, Decon Specialist, Medical Specialist, and other technical specialists
  21. 21. Williamson County HazMat Response Group Response Teams will include members from the Brentwood Fire Department, the Franklin Fire Department, the Williamson County Emergency Medical Services, and the Williamson County Emergency Management Agency. Will be a regional response team – able to respond wherever needed
  22. 22. Brentwood HazMat Equipment and Assets Rescue 1 is primary HM response vehicle  Carries PPE and decontamination equipment  Also carries HazCat kit and sampling equipment Each Engine carries air monitoring equipment and foam Car 2 carries air monitoring, radiological monitoring, and information resources
  23. 23. Training Requirements OSHA training levels include:  HM Awareness (no minimum hours)  HM Operations (minimum 8 hours)  HM Technician (minimum 24 hours)  HM Specialist (minimum 24 hours) OSHA-only certification/Not NFPA level  HM Incident Commander
  24. 24. Training Requirements TEMA training levels include:  HM Operations (32 hours)  HM Technician (additional 96 hours)  HM Specialist (additional 192 hours)
  25. 25. Certifications OSHA v. NFPA  NFPA 472  29 CFR 1910.120 Where?  TEMA  FEMA  USEPA
  26. 26. HM Awareness May come upon spill or leak during duty times (PD & Public Works) Protect nearby public and property by isolation and evacuation Defensive mode only Cannot contain or confine
  27. 27. HM Operations Respond to releases as the initial response (firefighters; some EMT’s) Protect nearby public and property by isolation and evacuation Defensive mode only Can contain but cannot confine
  28. 28. HM Technician Respond for the purpose of stopping the spill or leak (HM team members) Offensive role; confine the spill/leak Training requirements include:  HM Team Operations (TEMA)  Radiological Monitor (TEMA)
  29. 29. HM Specialist Provide support to HM Technicians (HM team leaders) More specific knowledge of detection and tactics Training requirements include:  Chemistry of HM (NFA)  HM Operating Site Practices (NFA)  Radiological Response Team (TEMA)
  30. 30. HM Incident Manager Specialized management of the HM incident (HM team officers) Most are higher trained than HM - Operations level 24 additional hours of training in HM incident management
  31. 31. Incident Management Model Isolation Notification Identification Protection Spill and Leak Control Fire Control Recovery and Termination
  32. 32. Isolation is Scene Control!!!
  33. 33. Initial Isolation Distances …are found in the North American Emergency Response Guidebook
  34. 34. Rule of Thumb Initial Isolation Distance is at least 150 feet…
  35. 35. THE NAERG A practical exercise…
  36. 36. Scene Control Scene control is accomplished by:  scene security isolation via PD  control zones hot, warm, and cold zones  safe response practices environmental health and safety medical control and surveillance
  37. 37. Control Zones Hot Zone = Exclusion zone Warm Zone = Contamination Reduction Zone Cold Zone = Support Zone
  38. 38. Hot Zone determined by air monitoring, meteorological conditions, geography, and HM product characteristics One way in - one way out Work area only in required PPE No eating, drinking, chewing, or “carrying on” “Get in then get out!”
  39. 39. Warm Zone  decontamination occurs here  PPE is required here  PPE level is generally one level below level required in the Hot Zone
  40. 40. Cold Zone The Command Post, the Incident Manager, support staff, and media are here No PPE is required! If it is, MOVE!!!
  41. 41. Notification Who you gonna call?
  42. 42. Notification Contacts Williamson County Emergency Management Agency  your “one stop shop!”  they will notify TEMA and others, if needed Responders can call the shipper, carrier, or CHEMTREC if they need to!!!
  43. 43. Identification What is that stuff?
  44. 44. On Scene Indicators  Occupancy/location  Placards/labels  Container shape  Shipping papers  Markings/colors  Senses
  45. 45. Occupancy/Location
  46. 46. Container Shape
  47. 47. Markings/Colors
  48. 48. Placards/Labels
  49. 49. Shipping Papers
  50. 50. Senses Sight – vapor clouds, fire, heat waves Sound – cracking, popping, creaking Smell – garlic, almonds, bleach Touch – hot, cold, stinging Taste – one word – “Don’t!” The most important sense is “Common”…
  51. 51. Instruments Air Monitoring Equipment Colorimetric tubes Radiological Detection Equipment Chemistry – HazCat Kit
  52. 52. Protection “Time, distance, and shielding…”
  53. 53. Protection Safety is increased by using:  the incident management system  an accountability system  “Two In-Two Out”  standardized procedures and techniques  effective decontamination  medical support and surveillance
  54. 54. Personal Protective Equipment “Asta lasagna, don’t get any onya”
  55. 55. Four Levels of PPE Level A - fully encapsulated Level B - non-encapsulated Level C - APR Level D - work clothing
  56. 56. Level A PPE Used in acidic and poisonous gaseous Used in unknown environments Maximal level of protection
  57. 57. Level B Uses Initial site entry Decontamination  decontamination of Level A  mass decontamination Patient care
  58. 58. Level C
  59. 59. Level D
  60. 60. Accountability
  61. 61. Decontamination
  62. 62. Medical Surveillance and Monitoring
  63. 63. Spill and Leak Control “Damming and Diking…”
  64. 64. Containment
  65. 65. Confinement
  66. 66. Fire Control “Hot stuff…”
  67. 67. Recovery
  68. 68. Termination “All good things must come to an end…”
