  1. Hydrogen Sulfide Suicide AKA Detergent Suicide By Michael Magda

  2. History • Japan 2008 • <2000 • 2009 • <3 • 2010 • <30 • 2011 • Michigan 1

  3. Colorless gas Rotten eggs odor Smell .02- .2 ppm Biological decay Sulfur-containing goods Sewage Manure Leafs, wood, animals Olfactory Deaden sense of smell .02-2. ppm Chemical asphyxiate Rendering cells dead Chemical irritant Eye and upper airway Hydrogen Sulfide (H2S)

  4. Vapor density 1.19 heaver than air Low to the ground Vapor knockdown Water spray Venting May not work Consider PPV Absorption Poisonous IDLH 100 ppm Autoignition 500°F Flammable gas LEL 4% UEL 44% H2S properties

  5. Mix Hydrochloric acid Sulfur compound Acid and base Exothermic Somewhat violent reaction ½ cup of each Produces 1000 ppm Average sized vehicle or 3,500 cubic feet of a confine space The concoction

  6. Acid Sources Muriatic acid Sulfuric acid Lysol disinfectant Lysol toilet bowl cleaner The Works, toilet bowl cleaner Kaboom Shower, Tub and Tile cleaner Tile and Stone cleaners Sulfur Sources Artist oil paints Dandruff shampoos Pesticides Spackling paste Latex paints Garden fungicides Lime Sulfur Bath Salts Typical Chemicals Used

  7. PPE • Incidents dictates PPE • Solids • liquids • Gases • Body fluids • SCBA • <100 ppm • Turnout or Tyvek

  8. First Responder Appropriate for contamination Victim Remove clothing Double-bag Follow SOG Off-gassing Lungs Clothing Notify Hospital Morgue Transport deceased in Body bag Enclosed vehicle Wrapped in sheets Open vehicle Preferred method Decontamination

  9. Exposure and Treatment

  10. Exposure and Treatment • Pulmonary edema • Up to 72 hours • Follow Protocols • Support • Cardiovascular • Seizures • Hypotension

  11. Decay 12-37 hours Colder= longer Warmer=shorter Internet sites Encourage warning signs Slowdown 10 seconds rule Size-up Look for clues Signage HCN or H2S Response

  12. Warning Signs / Vehicle

  13. Warning Signs / Vehicle • Subject slumped over in the vehicle • Suicide notes taped to the window • Suicide note inside vehicle • Yellow or green residue

  14. Warning Signs / Vehicle • Windows taped • Doors taped • Vents taped up

  15. Warning Signs / Vehicle • Tools used to mix the chemicals • Bottles of household chemicals • Containers used to mix the chemicals

  16. Warning Signs / Building • Motel • Doors and windows • Odors • Persons inside • DIB

  17. Trends • Increased internet activity • Younger people • Middle and high schools • Suicide pacts • Hydrogen cyanide

  18. Recap • ½ cup • Acid and sulfur compound • 1000 ppm • 3,500 cf • Several gallons • Linger for hours

  19. Slowdown Look for clues signs Pails, buckets mixing vessels Acids and pesticides PPE SCBA Air monitoring Follow SOG’s Protect yourself Recap
