1 Hydrogen Sulfide Suicide AKA Detergent Suicide By Michael Magda

2 History Japan 2008 – < – < – < – Michigan 1

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

4 H2S properties 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%

5 The concoction 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

6 Typical Chemicals Used 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

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

8 Decontamination 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

9 Exposure and Treatment

10 Pulmonary edema – Up to 72 hours Follow Protocols Support – Cardiovascular – Seizures – Hypotension

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

12 Warning Signs / Vehicle

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