  1. CBRNE Training Academy Hazards

  2. Lecture Goals • Define what a hazard is • Define “all hazards” approach • Describe where hazards exist • Explain hazard recognition

  3. What is a hazardous substance? • Any substance . . . • Solid • Liquid • Gas • Other • Capable of harming . . . • People • Property • Environment

  4. What is a hazardous substance? • Any substance to which exposure • “Results or may result in adverse affects on the health or safety of employees” • “Any chemical which is a physical hazard or a health hazard” • OSHA 29 CFR 1910.1200 (c) • Bottom line: Adversely affects health or safety (not only chemicals . . .)

  5. “All Hazards”

  6. “All Hazards” • Knowledge that you have • Applied to unknown situations • Common, standard approach • Instills confidence • Quells fear • Ensures safety, always Prepared for the mundane = Prepared for the exotic

  7. Hazards = Potential Events • Awareness identifies hazards • “Guns don’t kill people . . .” • Potential depends on scale and scope • Spill coffee • Spill sarin • Spill oil (tanker)

  8. Lab Pharmacy OR Building Services Engineering Environmental Services Bio-med Central Supply Respiratory Dietary Radiology Nuclear Medicine Oncology Laundry EMS ED Med Air / O2 What’s in your hospital?

  9. Where do hazards exist? EVERYWHERE • Setting is artificial distinction • Familiarity creates false comfort • Things we know, context we don’t • Medical O2 vs. Industrial O2 • Location doesn’t modify nature* • Awareness recognizes potential harm

  10. All Hazards • People at risk = hazard • Site independent • Preparation and prevention is the same • Scale and scope is different • Intent is the confounding factor • Remove intent, left with event

  11. Specific hazards • Things that are infectious • Things that explode • Things that burn, shock • Things that are corrosive • Things that are radioactive • Things that cause cancer • Things that are poisonous through other means • “Others”

  12. D.O.T. Classification

  13. Specific examples • Scale, scope and intent • Things that are familiar • Things in unfamiliar context • Things with malicious intent

  14. Flammable liquids • Found in all environments • Often overlooked, ignored as risk • Fire and explosive risk • Let’s take a look at a familiar example…

  15. Flammable liquids Ethyl alcohol

  16. Flammable liquids Gasoline

  17. Flammable liquids

  18. All Hazards • Everything is a potential hazard • Hazards have many faces • Recognize the potential exists • Remove the intent • Prepared and ready

  19. Gases • Found everywhere in a hospital • Flammable, compressed • Boiling Liquid Expanding Vapor Explosion (B.L.E.V.E.) • Some are toxic • Let’s take a look at another familiar example…

  20. Normal chest x-ray ARDS chest x-ray Chlorine gas • Severe pulmonary toxin • Causes delayed lung injury Cl2 + =

  21. HCl + HOCl Cl2 My bathroom January 10, 2005

  22. South Carolina January 6, 2005

  23. Ypres, Belgium April 22, 1915

  24. Other gas examples Oxygen & other compressed gases

  25. In a different context

  26. All Hazards • Everything is a potential hazard • Hazards have many faces • Recognize the potential exists • Remove the intent • Prepared and ready

  27. Oxidizers • Enhance / cause combustion of others • Cause fire by itself, or by releasing O2 • Involved in reactive processes

  28. Oxidizers Ammonium nitrate

  29. Oxidizers Ammonium nitrate

  30. Oxidizers

  31. All Hazards • Everything is a potential hazard • Hazards have many faces • Recognize the potential exists • Remove the intent • Prepared and ready

  32. Toxins or poisons • Vast category, hard to generalize • Found everywhere • Especially in healthcare • Home • Industry • Lets take a look at an example from the hospital lab . . .

  33. Toxins or poisons

  34. Toxins or poisons

  35. Toxins or poisons

  36. All Hazards • Everything is a potential hazard • Hazards have many faces • Recognize the potential exists • Remove the intent • Prepared and ready

  37. Radioactivity • Cause harm through energy • Background radiation and specific sources • Radiology department • Nuclear medicine • Power plants • Industry • Lets take a look at an example from the nuclear medicine department . . .

  41. All Hazards • Everything is a potential hazard • Hazards have many faces • Recognize the potential exists • Remove the intent • Prepared and ready

  42. Where can we learn more? • On-scene personnel • Police, Fire, EMS, HazMat, etc. • Industrial Safety officer • Poison Control Center • Labels • Material Safety Data Sheets (MSDS) • Emergency Response Guidebook (ERG) • Agency for Toxic Substance & Disease Registry (ATSDR) • Internet resources
