1 Presented by City of Raleigh Fire Department Hazmat Team “Detergent Suicide”Presented byCity of Raleigh Fire DepartmentHazmat Team
2 What is “Detergent Suicide?” Name comes from the type of “ingredients” usedMixture of toilet bowl cleaner and an organic phosphate – insecticide, fungicideSometimes Muriatic or Sulfuric Acid is substituted for cleanerOriginated in Japan – slowly proliferating all over the world
3 Hydrogen Sulfide What happens? Mixing the aforementioned chemicals together produces a deadly gas:Hydrogen Sulfide
4 What is Hydrogen Sulfide? Toxic, colorless gasSmells like rotten eggsExtremely flammable
5 Properties IDLH: 100 ppm Flammable Range: 4% to 46% Ignition temp approx. 5000FVapor Density: 1.2 (Heavier than air)Vapor 680F is 17.6 atmIt will dissipate quickly outside
6 Toxic Levels of Concern Odor Threshold: .001 to 0.13 ppmOlfactory Fatigue begins at about 20 ppmTen minute AEGL-2: 41 ppmIrreversible, serious, long-lasting effects or impaired ability to escape.
7 Signs and SymptomsTarget Organs: Eyes, Respiratory Tract, Central Nervous SystemSymptoms:Eye, mucous membrane and skin irritationMemory loss, confusion, headache, dizzinessShortness of breath, cough, tightness in the chest, pulmonary edemaDifficulty breathing/swallowing, abdominal pain, nausea, vomiting, diarrheaTremors, convulsions, coma
8 Basic Life Support Remove victim from exposure Decontaminate Brush solids from clothing (if any)Remove clothing – contain for disposal.Flush victim with copious amounts of water using mild detergent – minimum 15 minutesFlush eyes with lukewarm water – minimum 15 minutes
9 Basic Life Support, cont’d… Administer Oxygen, LPM via NRBTransport immediately to HospitalAdvanced Life Support…Refer to local protocol
10 Basic Life Support, cont’d… NOTE: Performing these BLS and decontamination functions should be performed wearing appropriate PPEThis includes;Level C PPE – Chemical splash suit, nitrile gloves, chemical boots, appropriate respiratorUse SCBA if victim’s area concentrations were greater than 100 ppm
11 Scene size-up Some scenes will be obvious… Well marked with warnings Obvious chemicals in the vehicle/structure
13 Things to consider Overall scene safety Does the scene appear to be unusual in any way? Signage, odors, victims?Inside or outside? The gas - if present – will persist much longer in an enclosed spaceAny indicators that chemicals are present?Victim slumped over steering wheel?Bystanders showing signs and symptoms of H2S?
14 Things to consider, cont’d… A yes to any one of the previous items would be cause for concernCall HazmatDO NOT make entry into the vehicle or building/room.Keep all ignition sources away from area
15 Things to consider, cont’d… Monitoring for H2S with a monitor calibrated with a gas other than H2S will require the use of a correction factorRae Systems correction factors for their MultiRae PID’s are as follows (if calibrated with 100ppm isobutylene):For 10.6 eV – 3.3For 11.7 eV – 1.5
16 Items for the futureWe have been lucky so far – incidents have been outside and marked with warning signsIn Japan, this occurs in apartment buildings – many others become involvedMeth labs could be “booby-trapped” with this type of deviceHostage situations may involve this – firing a “flash-bang” grenade into this type of environment would be very explosive
17 Recent OccurrencesYet another detergent suicide forced residents of an apartment building to evacuate on June 4, residents were evacuated and one woman was taken to the hospital. The suicide victim was in his late 20s.On May 1, 2008, 350 people had to be evacuated from their homes in Otaru, northern Japan - a man used this technique to kill himself.On April 23, 2008, in Konan, Japan, a 14-year-old girl killed herself by mixing laundry detergent with a liquid cleanser. The gas seeped out a window and into neighboring apartments, sickening 90 people and causing 10 to be admitted to the hospital.
18 DemonstrationThe video shows the reaction of 8 fl. oz. of Muriatic Acid mixed with 8 fl. oz. of Sulfur Lime. Enclosed in a compact car.A time line of the video is shown on the next slide
19 Time Line of Video Chemicals mixed at time (t)=o seconds (s) Vehicle door closed at t= 3 sMeter alarms at t = 14 sInitial meter spike at t = 17 sLevels drop initially, then begin to rise as vehicle fills with gasMeter level shows 171 ppm at t = 1 minuteMeter reading maintained approx. 171 ppm until vehicle doors opened
